Richard I of England - lionheart
Richard I (8 September 1157 – 6 April 1199) was King of England from 6 July 1189 until his death. He also ruled as Duke of Normandy, Aquitaine and Gascony, Lord of Cyprus, Count of Poitiers, Anjou, Maine, and Nantes, and Overlord of Brittany at various times during the same period. He was the third of five sons of King Henry II of England and Duchess Eleanor of Aquitaine. He was known as Richard Cœur de Lion or Richard the Lionheart because of his reputation as a great military leader and warrior. He was also known in Occitan as Oc e No (Yes and No), because of his reputation for terseness.
By the age of 16, Richard had taken command of his own army, putting down rebellions in Poitou against his father. Richard was a central Christian commander during the Third Crusade, leading the campaign after the departure of Philip II of France and scoring considerable victories against his Muslim counterpart, Saladin, although he did not retake Jerusalem from Saladin.
Richard spoke both French and Occitan. He was born in England, where he spent his childhood; before becoming king, however, he lived for most of his adult life in the Duchy of Aquitaine in the southwest of France. Following his accession he spent very little time, perhaps as little as six months, in England; most of his life as king was spent on Crusade, in captivity, or in actively defending his lands in France. Rather than regarding his kingdom as a responsibility requiring his presence as ruler, he has been perceived as preferring to use it merely as a source of revenue to support his armies. Nevertheless, he was seen as a pious hero by his subjects. He remains one of the few kings of England remembered by his epithet, rather than regnal number, and is an enduring iconic figure both in England and in France.
Early life and accession in Aquitaine
Childhood
Richard was born on 8 September 1157,probably at Beaumont Palace, in Oxford, England, son of King Henry II and Eleanor of Aquitaine. He was a younger brother of Count William IX of Poitiers, Henry the Young King and Duchess Matilda of Saxony. As the third legitimate son of King Henry II, he was not expected to ascend the throne. He was also an elder brother of Duke Geoffrey II of Brittany; Queen Eleanor of Castile; Queen Joan of Sicily; and Count John of Mortain, who succeeded him as king. Richard was the younger maternal half-brother of Countess Marie of Champagne and Countess Alix of Blois. The eldest son of Henry II and Eleanor, William, died in 1156, before Richard's birth. Richard is often depicted as having been the favourite son of his mother. His father was Angevin-Norman and great-grandson of William the Conqueror. Contemporary historian Ralph of Diceto traced his family's lineage through Matilda of Scotland to the Anglo-Saxon kings of England and Alfred the Great, and from there linked them to Noah and Woden. According to Angevin legend, there was even infernal blood in the family.
While his father visited his lands from Scotland to France, Richard probably spent his childhood in England. His first recorded visit to the European continent was in May 1165, when his mother took him to Normandy. His wet nurse was Hodierna of St Albans, whom he gave a generous pension after he became king. Little is known about Richard's education. Although he was born in Oxford and brought up in England up to his eighth year, it is not known to what extent he used or understood English; he was an educated man who composed poetry and wrote in Limousin (lenga d'òc) and also in French. During his captivity, English prejudice against foreigners was used in a calculated way by his brother John to help destroy the authority of Richard's chancellor, William Longchamp, who was a Norman. One of the specific charges laid against Longchamp, by John's supporter Hugh, Bishop of Coventry, was that he could not speak English. This indicates that by the late 12th century a knowledge of English was expected of those in positions of authority in England.
Richard was said to be very attractive; his hair was between red and blond, and he was light-eyed with a pale complexion. He was apparently of above average height: according to Clifford Brewer he was 6 feet 5 inches (1.96 m). As with his supposed lack of English, the question of his stature is one made from a lack of evidence as his remains have been lost since at least the French Revolution, and his exact height is unknown. John, his youngest brother (by the same father and mother), was known to be only 5 feet 5 inches (1.65 m). The Itinerarium peregrinorum et gesta regis Ricardi, a Latin prose narrative of the Third Crusade, states that: "He was tall, of elegant build; the colour of his hair was between red and gold; his limbs were supple and straight. He had long arms suited to wielding a sword. His long legs matched the rest of his body."
From an early age he showed significant political and military ability, becoming noted for his chivalry and courage as he fought to control the rebellious nobles of his own territory. His elder brother Henry the Young King was crowned king of England during his father's lifetime.
Marriage alliances were common among medieval royalty: they led to political alliances and peace treaties, and allowed families to stake claims of succession on each other's lands. In March 1159 it was arranged that Richard would marry one of the daughters of Ramon Berenguer IV, Count of Barcelona; however, these arrangements failed, and the marriage never took place. Henry the Young King was married to Margaret, daughter of Louis VII of France, on 2 November 1160. Despite this alliance between the Plantagenets and the Capetians, the dynasty on the French throne, the two houses were sometimes in conflict. In 1168, the intercession of Pope Alexander III was necessary to secure a truce between them. Henry II had conquered Brittany and taken control of Gisors and the Vexin, which had been part of Margaret's dowry.
Early in the 1160s there had been suggestions Richard should marry Alys, Countess of the Vexin (Alice), fourth daughter of Louis VII; because of the rivalry between the kings of England and France, Louis obstructed the marriage. A peace treaty was secured in January 1169 and Richard's betrothal to Alys was confirmed. Henry II planned to divide his and Eleanor's territories among their three eldest surviving sons: Henry would become King of England and have control of Anjou, Maine, and Normandy; Richard would inherit Aquitaine and Poitiers from his mother; and Geoffrey would become Duke of Brittany through marriage with Constance, heir presumptive of Conan IV. At the ceremony where Richard's betrothal was confirmed, he paid homage to the King of France for Aquitaine, thus securing ties of vassalage between the two.
After Henry II fell seriously ill in 1170, he put in place his plan to divide his kingdom, although he would retain overall authority over his sons and their territories. In 1171 Richard left for Aquitaine with his mother, and Henry II gave him the duchy of Aquitaine at the request of Eleanor. Richard and his mother embarked on a tour of Aquitaine in 1171 in an attempt to pacify the locals. Together they laid the foundation stone of St Augustine's Monastery in Limoges. In June 1172 Richard was formally recognised as the Duke of Aquitaine when he was granted the lance and banner emblems of his office; the ceremony took place in Poitiers and was repeated in Limoges, where he wore the ring of St Valerie, who was the personification of Aquitaine.
Revolt against Henry II
According to Ralph of Coggeshall, Henry the Young King instigated rebellion against Henry II; he wanted to reign independently over at least part of the territory his father had promised him, and to break away from his dependence on Henry II, who controlled the purse strings. There were rumors that Eleanor might have encouraged her sons to revolt against their father.
Henry the Young King abandoned his father and left for the French court, seeking the protection of Louis VII; his younger brothers, Richard and Geoffrey, soon followed him, while the five-year-old John remained in England. Louis gave his support to the three sons and even knighted Richard, tying them together through vassalage.Jordan Fantosme, a contemporary poet, described the rebellion as a "war without love".
The three brothers made an oath at the French court that they would not make terms with Henry II without the consent of Louis VII and the French barons. With the support of Louis, Henry the Young King attracted many barons to his cause through promises of land and money; one such baron was Philip, Count of Flanders, who was promised £1,000 and several castles. The brothers also had supporters ready to rise up in England. Robert de Beaumont, 3rd Earl of Leicester, joined forces with Hugh Bigod, 1st Earl of Norfolk, Hugh de Kevelioc, 5th Earl of Chester, and William I of Scotland for a rebellion in Suffolk. The alliance with Louis was initially successful, and by July 1173 the rebels were besieging Aumale, Neuf-Marché, and Verneuil, and Hugh de Kevelioc had captured Dol in Brittany. Richard went to Poitou and raised the barons who were loyal to himself and his mother in rebellion against his father. Eleanor was captured, so Richard was left to lead his campaign against Henry II's supporters in Aquitaine on his own. He marched to take La Rochelle but was rejected by the inhabitants; he withdrew to the city of Saintes, which he established as a base of operations.
In the meantime Henry II had raised a very expensive army of more than 20,000 mercenaries with which to face the rebellion. He marched on Verneuil, and Louis retreated from his forces. The army proceeded to recapture Dol and subdued Brittany. At this point Henry II made an offer of peace to his sons; on the advice of Louis the offer was refused. Henry II's forces took Saintes by surprise and captured much of its garrison, although Richard was able to escape with a small group of soldiers. He took refuge in Château de Taillebourg for the rest of the war. Henry the Young King and the Count of Flanders planned to land in England to assist the rebellion led by the Earl of Leicester. Anticipating this, Henry II returned to England with 500 soldiers and his prisoners (including Eleanor and his sons' wives and fiancées), but on his arrival found out that the rebellion had already collapsed. William I of Scotland and Hugh Bigod were captured on 13 and 25 July respectively. Henry II returned to France and raised the siege of Rouen, where Louis VII had been joined by Henry the Young King after abandoning his plan to invade England. Louis was defeated and a peace treaty was signed in September 1174, the Treaty of Montlouis.
When Henry II and Louis VII made a truce on 8 September 1174, its terms specifically excluded Richard. Abandoned by Louis and wary of facing his father's army in battle, Richard went to Henry II's court at Poitiers on 23 September and begged for forgiveness, weeping and falling at the feet of Henry, who gave Richard the kiss of peace.Several days later, Richard's brothers joined him in seeking reconciliation with their father. The terms the three brothers accepted were less generous than those they had been offered earlier in the conflict (when Richard was offered four castles in Aquitaine and half of the income from the duchy): Richard was given control of two castles in Poitou and half the income of Aquitaine; Henry the Young King was given two castles in Normandy; and Geoffrey was permitted half of Brittany. Eleanor remained Henry II's prisoner until his death, partly as insurance for Richard's good behaviour.

Alexander the Great - King of Macedon
Accession
In summer 336 BC, while at Aegae attending the wedding of his daughter Cleopatra to Olympias's brother, Alexander I of Epirus, Philip was assassinated by the captain of his bodyguards, Pausanias. As Pausanias tried to escape, he tripped over a vine and was killed by his pursuers, including two of Alexander's companions, Perdiccas and Leonnatus. Alexander was proclaimed king by the nobles and armyat the age of 20.
Consolidation of power
Alexander began his reign by eliminating potential rivals to the throne. He had his cousin, the former Amyntas IV, executed. He also had two Macedonian princes from the region of Lyncestis killed, but spared a third, Alexander Lyncestes. Olympias had Cleopatra Eurydice and Europa, her daughter by Philip, burned alive. When Alexander learned about this, he was furious. Alexander also ordered the murder of Attalus, who was in command of the advance guard of the army in Asia Minor and Cleopatra's uncle.
Attalus was at that time corresponding with Demosthenes, regarding the possibility of defecting to Athens. Attalus also had severely insulted Alexander, and following Cleopatra's murder, Alexander may have considered him too dangerous to leave alive. Alexander spared Arrhidaeus, who was by all accounts mentally disabled, possibly as a result of poisoning by Olympias.
News of Philip's death roused many states into revolt, including Thebes, Athens, Thessaly, and the Thracian tribes north of Macedon. When news of the revolts reached Alexander, he responded quickly. Though advised to use diplomacy, Alexander mustered 3,000 Macedonian cavalry and rode south towards Thessaly. He found the Thessalian army occupying the pass between Mount Olympus and Mount Ossa, and ordered his men to ride over Mount Ossa. When the Thessalians awoke the next day, they found Alexander in their rear and promptly surrendered, adding their cavalry to Alexander's force. He then continued south towards the Peloponnese.
Alexander stopped at Thermopylae, where he was recognized as the leader of the Amphictyonic League before heading south to Corinth. Athens sued for peace and Alexander pardoned the rebels. The famous encounter between Alexander and Diogenes the Cynic occurred during Alexander's stay in Corinth. When Alexander asked Diogenes what he could do for him, the philosopher disdainfully asked Alexander to stand a little to the side, as he was blocking the sunlight.This reply apparently delighted Alexander, who is reported to have said "But verily, if I were not Alexander, I would like to be Diogenes." At Corinth, Alexander took the title of Hegemon ("leader") and, like Philip, was appointed commander for the coming war against Persia. He also received news of a Thracian uprising.

Alexander the Great And his early life
Alexander III of Macedon (20/21 July 356 BC – 10/11 June 323 BC), commonly known as Alexander the Great (Greek: Ἀλέξανδρος ὁ Μέγας, Aléxandros ho Mégas Koine Greek: [a.lék.san.dros ho mé.gas] ), was a king (basileus) of the Ancient Greek kingdom of Macedon and a member of the Argead dynasty. Born in Pella in 356 BC, Alexander succeeded his father, Philip II, to the throne at the age of twenty. He spent most of his ruling years on an unprecedented military campaign through Asia and northeast Africa, and by the age of thirty he had created one of the largest empires of the ancient world, stretching from Greece to northwestern India. He was undefeated in battle and is widely considered one of history's most successful military commanders.
During his youth, Alexander was tutored by the philosopher Aristotle until the age of 16. After Philip's assassination in 336 BC, Alexander succeeded his father to the throne and inherited a strong kingdom and an experienced army. Alexander was awarded the generalship of Greece and used this authority to launch his father's Panhellenic project to lead the Greeks in the conquest of Persia. In 334 BC, he invaded the Achaemenid Empire, and began a series of campaigns that lasted ten years. Following the conquest of Asia Minor, Alexander broke the power of Persia in a series of decisive battles, most notably the battles of Issus and Gaugamela. He subsequently overthrew the Persian King Darius III and conquered the Achaemenid Empire in its entirety. At that point, his empire stretched from the Adriatic Sea to the Indus River.
Seeking to reach the "ends of the world and the Great Outer Sea", he invaded India in 326 BC, but eventually turned back at the demand of his homesick troops. Alexander died in Babylon in 323 BC, the city he planned to establish as his capital, without executing a series of planned campaigns that would have begun with an invasion of Arabia. In the years following his death, a series of civil wars tore his empire apart, resulting in several states ruled by the Diadochi, Alexander's surviving generals and heirs.
Alexander's legacy includes the cultural diffusion his conquests engendered, such as Greco-Buddhism. He founded some twenty cities that bore his name, most notably Alexandria in Egypt. Alexander's settlement of Greek colonists and the resulting spread of Greek culture in the east resulted in a new Hellenistic civilization, aspects of which were still evident in the traditions of the Byzantine Empire in the mid-15th century and the presence of Greek speakers in central and far eastern Anatolia until the 1920s. Alexander became legendary as a classical hero in the mold of Achilles, and he features prominently in the history and mythic traditions of both Greek and non-Greek cultures. He became the measure against which military leaders compared themselves, and military academies throughout the world still teach his tactics. He is often ranked among the most influential people in human history, along with his teacher Aristotle.
Lineage and childhood
Alexander was born on the sixth day of the ancient Greek month of Hekatombaion, which probably corresponds to 20 July 356 BC, although the exact date is disputed,in Pella, the capital of the Kingdom of Macedon. He was the son of the king of Macedon, Philip II, and his fourth wife, Olympias, the daughter of Neoptolemus I, king of Epirus. Although Philip had seven or eight wives, Olympias was his principal wife for some time, likely a result of giving birth to Alexander.
Several legends surround Alexander's birth and childhood. According to the ancient Greek biographer Plutarch, Olympias, on the eve of the consummation of her marriage to Philip, dreamed that her womb was struck by a thunder bolt, causing a flame that spread "far and wide" before dying away. Sometime after the wedding, Philip is said to have seen himself, in a dream, securing his wife's womb with a sealengraved with a lion's image. Plutarch offered a variety of interpretations of these dreams: that Olympias was pregnant before her marriage, indicated by the sealing of her womb; or that Alexander's father was Zeus. Ancient commentators were divided about whether the ambitious Olympias promulgated the story of Alexander's divine parentage, variously claiming that she had told Alexander, or that she dismissed the suggestion as impious.
On the day Alexander was born, Philip was preparing a siege on the city of Potidea on the peninsula of Chalcidice. That same day, Philip received news that his general Parmenion had defeated the combined Illyrian and Paeonian armies, and that his horses had won at the Olympic Games. It was also said that on this day, the Temple of Artemis in Ephesus, one of the Seven Wonders of the World, burnt down. This led Hegesias of Magnesia to say that it had burnt down because Artemis was away, attending the birth of Alexander. Such legends may have emerged when Alexander was king, and possibly at his own instigation, to show that he was superhuman and destined for greatness from conception.
In his early years, Alexander was raised by a nurse, Lanike, sister of Alexander's future general Cleitus the Black. Later in his childhood, Alexander was tutored by the strict Leonidas, a relative of his mother, and by Lysimachus of Acarnania. Alexander was raised in the manner of noble Macedonian youths, learning to read, play the lyre, ride, fight, and hunt.
When Alexander was ten years old, a trader from Thessaly brought Philip a horse, which he offered to sell for thirteen talents. The horse refused to be mounted and Philip ordered it away. Alexander however, detecting the horse's fear of its own shadow, asked to tame the horse, which he eventually managed. Plutarch stated that Philip, overjoyed at this display of courage and ambition, kissed his son tearfully, declaring: "My boy, you must find a kingdom big enough for your ambitions. Macedon is too small for you", and bought the horse for him. Alexander named it Bucephalas, meaning "ox-head". Bucephalas carried Alexander as far as India. When the animal died (due to old age, according to Plutarch, at age thirty), Alexander named a city after him, Bucephala.
Adolescence and education
When Alexander was 13, Philip began to search for a tutor, and considered such academics as Isocrates and Speusippus, the latter offering to resign to take up the post. In the end, Philip chose Aristotle and provided the Temple of the Nymphs at Mieza as a classroom. In return for teaching Alexander, Philip agreed to rebuild Aristotle's hometown of Stageira, which Philip had razed, and to repopulate it by buying and freeing the ex-citizens who were slaves, or pardoning those who were in exile.
Mieza was like a boarding school for Alexander and the children of Macedonian nobles, such as Ptolemy, Hephaistion, and Cassander. Many of these students would become his friends and future generals, and are often known as the 'Companions'. Aristotle taught Alexander and his companions about medicine, philosophy, morals, religion, logic, and art. Under Aristotle's tutelage, Alexander developed a passion for the works of Homer, and in particular the Iliad; Aristotle gave him an annotated copy, which Alexander later carried on his campaigns.

Scientific revolution - part 3
Chemistry
Chemistry, and its antecedent alchemy, became an increasingly important aspect of scientific thought in the course of the 16th and 17th centuries. The importance of chemistry is indicated by the range of important scholars who actively engaged in chemical research. Among them were the astronomer Tycho Brahe, the chemical physician Paracelsus, Robert Boyle, Thomas Browne and Isaac Newton. Unlike the mechanical philosophy, the chemical philosophy stressed the active powers of matter, which alchemists frequently expressed in terms of vital or active principles—of spirits operating in nature.
Practical attempts to improve the refining of ores and their extraction to smelt metals was an important source of information for early chemists in the 16th century, among them Georg Agricola (1494–1555), who published his great work De re metallica in 1556. His work describes the highly developed and complex processes of mining metal ores, metal extraction and metallurgy of the time. His approach removed the mysticism associated with the subject, creating the practical base upon which others could build.
English chemist Robert Boyle (1627–1691) is considered to have refined the modern scientific method for alchemy and to have separated chemistry further from alchemy. Although his research clearly has its roots in the alchemical tradition, Boyle is largely regarded today as the first modern chemist, and therefore one of the founders of modern chemistry, and one of the pioneers of modern experimental scientific method. Although Boyle was not the original discover, he is best known for Boyle's law, which he presented in 1662: the law describes the inversely proportional relationship between the absolute pressure and volume of a gas, if the temperature is kept constant within a closed system.
Boyle is also credited for his landmark publication The Sceptical Chymist in 1661, which is seen as a cornerstone book in the field of chemistry. In the work, Boyle presents his hypothesis that every phenomenon was the result of collisions of particles in motion. Boyle appealed to chemists to experiment and asserted that experiments denied the limiting of chemical elements to only the classic four: earth, fire, air, and water. He also pleaded that chemistry should cease to be subservient to medicine or to alchemy, and rise to the status of a science. Importantly, he advocated a rigorous approach to scientific experiment: he believed all theories must be proved experimentally before being regarded as true. The work contains some of the earliest modern ideas of atoms, molecules, and chemical reaction, and marks the beginning of the history of modern chemistry.
Optics
Important work was done in the field of optics. Johannes Kepler published Astronomiae Pars Optica (The Optical Part of Astronomy) in 1604. In it, he described the inverse-square law governing the intensity of light, reflection by flat and curved mirrors, and principles of pinhole cameras, as well as the astronomical implications of optics such as parallax and the apparent sizes of heavenly bodies. Astronomiae Pars Optica is generally recognized as the foundation of modern optics (though the law of refraction is conspicuously absent).
Willebrord Snellius (1580–1626) found the mathematical law of refraction, now known as Snell's law, in 1621. Subsequently René Descartes (1596–1650) showed, by using geometric construction and the law of refraction (also known as Descartes' law), that the angular radius of a rainbow is 42° (i.e. the angle subtended at the eye by the edge of the rainbow and the rainbow's centre is 42°). He also independently discovered the law of reflection, and his essay on optics was the first published mention of this law.
Christiaan Huygens (1629–1695) wrote several works in the area of optics. These included the Opera reliqua (also known as Christiani Hugenii Zuilichemii, dum viveret Zelhemii toparchae, opuscula posthuma) and the Traité de la lumière.
Isaac Newton investigated the refraction of light, demonstrating that a prism could decompose white light into a spectrum of colours, and that a lens and a second prism could recompose the multicoloured spectrum into white light. He also showed that the coloured light does not change its properties by separating out a coloured beam and shining it on various objects. Newton noted that regardless of whether it was reflected or scattered or transmitted, it stayed the same colour. Thus, he observed that colour is the result of objects interacting with already-coloured light rather than objects generating the colour themselves. This is known as Newton's theory of colour. From this work he concluded that any refracting telescope would suffer from the dispersion of light into colours. The interest of the Royal Societyencouraged him to publish his notes On Colour (later expanded into Opticks). Newton argued that light is composed of particles or corpuscles and were refracted by accelerating toward the denser medium, but he had to associate them with waves to explain the diffraction of light.
In his Hypothesis of Light of 1675, Newton posited the existence of the ether to transmit forces between particles. In 1704, Newton published Opticks, in which he expounded his corpuscular theory of light. He considered light to be made up of extremely subtle corpuscles, that ordinary matter was made of grosser corpuscles and speculated that through a kind of alchemical transmutation "Are not gross Bodies and Light convertible into one another, ...and may not Bodies receive much of their Activity from the Particles of Light which enter their Composition?"
Electricity
Dr. William Gilbert, in De Magnete, invented the New Latin word electricus from ἤλεκτρον (elektron), the Greek word for "amber". Gilbert undertook a number of careful electrical experiments, in the course of which he discovered that many substances other than amber, such as sulphur, wax, glass, etc. were capable of manifesting electrical properties. Gilbert also discovered that a heated body lost its electricity and that moisture prevented the electrification of all bodies, due to the now well-known fact that moisture impaired the insulation of such bodies. He also noticed that electrified substances attracted all other substances indiscriminately, whereas a magnet only attracted iron. The many discoveries of this nature earned for Gilbert the title of founder of the electrical science. By investigating the forces on a light metallic needle, balanced on a point, he extended the list of electric bodies, and found also that many substances, including metals and natural magnets, showed no attractive forces when rubbed. He noticed that dry weather with north or east wind was the most favourable atmospheric condition for exhibiting electric phenomena—an observation liable to misconception until the difference between conductor and insulator was understood.
Robert Boyle also worked frequently at the new science of electricity, and added several substances to Gilbert's list of electrics. He left a detailed account of his researches under the title of Experiments on the Origin of Electricity. Boyle, in 1675, stated that electric attraction and repulsion can act across a vacuum. One of his important discoveries was that electrified bodies in a vacuum would attract light substances, this indicating that the electrical effect did not depend upon the air as a medium. He also added resin to the then known list of electrics.
This was followed in 1660 by Otto von Guericke, who invented an early electrostatic generator. By the end of the 17th Century, researchers had developed practical means of generating electricity by friction with an electrostatic generator, but the development of electrostatic machines did not begin in earnest until the 18th century, when they became fundamental instruments in the studies about the new science of electricity. The first usage of the word electricity is ascribed to Sir Thomas Browne in his 1646 work, Pseudodoxia Epidemica. In 1729 Stephen Gray (1666–1736) demonstrated that electricity could be "transmitted" through metal filaments.
