Andrzej Tadeusz Bonawentura Kościuszko (English: Andrew Thaddeus Bonaventure Kosciuszko; 4 or 12 February 1746 – 15 October 1817) was a Polish military engineer, statesman, and military leader who then became a national hero in Poland, the United States, and Belarus. He fought in the Polish–Lithuanian Commonwealth's struggles against Russia and Prussia, and on the U.S. side in the American Revolutionary War. As Supreme Commander of the Polish National Armed Forces, he led the 1794 Kościuszko Uprising.

Kościuszko was born in February 1746, in a manor house on the Mereczowszczyzna estate in Brest Litovsk Voivodeship, then Grand Duchy of Lithuania, a part of the Polish–Lithuanian Commonwealth, now the Ivatsevichy District of Belarus. At age 20, he graduated from the Corps of Cadets in Warsaw, Poland. After the start of the civil war in 1768, Kościuszko moved to France in 1769 to study. He returned to the Commonwealth in 1774, two years after the First Partition, and was a tutor in Józef Sylwester Sosnowski's household. In 1776, Kościuszko moved to North America, where he took part in the American Revolutionary War as a colonel in the Continental Army. An accomplished military architect, he designed and oversaw the construction of state-of-the-art fortifications, including those at West Point, New York. In 1783, in recognition of his services, the Continental Congress promoted him to brigadier general. (Full article...)

Raymond III (1140 – September/October 1187) was count of Tripoli from 1152 to 1187. He was a minor when Nizari Assassins murdered his father, Raymond II of Tripoli. Baldwin III of Jerusalem, who was staying in Tripoli, made Raymond's mother, Hodierna of Jerusalem, regent. Raymond spent the following years at the royal court in Jerusalem. He reached the age of majority in 1155, after which he participated in a series of military campaigns against Nur ad-Din, the Zengid ruler of Damascus. In 1161 he hired pirates to pillage the Byzantine coastline and islands to take vengeance on Byzantine emperor Manuel I Komnenos, who had refused to marry his sister Melisende. He was captured in the Battle of Harim by Nur ad-Din's troops on 10 August 1164, and imprisoned in Aleppo for almost ten years. During his captivity, Amalric I of Jerusalem administered the county of Tripoli on his behalf.

Raymond was released for a large ransom which he had to borrow from the Knights Hospitaller. He married Eschiva of Bures, making him prince of Galilee and one of the wealthiest noblemen in the Kingdom of Jerusalem. Amalric died in 1174, leaving a minor son, Baldwin IV, as his successor. As the child-king's closest male relative, Raymond was elected bailiff (or regent). Raymond remained neutral during the conflicts between Nur ad-Din's successors and his former commander, Saladin, which facilitated the unification of Egypt and a significant part of Syria under Saladin. When Baldwin reached the age of majority in 1176, Raymond's regency ended and he returned to Tripoli. Baldwin was ailing, and Raymond and Bohemond III of Antioch sought to diminish the influence of his mother, Agnes of Courtenay, and her brother, Joscelin III of Edessa, over the government. Before Easter 1180, they marched to Jerusalem, but their arrival had the opposite effect: Baldwin promptly arranged for his sister and heir Sibylla to be married to Guy of Lusignan, a supporter of the Courtenays, and Raymond had to leave the kingdom. In the following years, relations between Baldwin IV and Guy became tense, and the dying king disinherited his sister in favour of her son Baldwin V. On his deathbed In 1185, the king made Raymond bailiff for Baldwin V. Raymond's authority would be limited, because Joscelin III of Edessa was made the child's guardian, and all royal fortresses were placed into the custody of the military orders. (Full article...)

Muhammad II (Arabic: محمد الثاني) (also known by the epithet al-Faqih, "the canon-lawyer", c. 1235 – 8 April 1302; reigned from 1273 until his death) was the second Nasrid ruler of the Emirate of Granada in Al-Andalus on the Iberian Peninsula, succeeding his father, Muhammad I. Already experienced in matters of state when he ascended the throne, he continued his father's policy of maintaining independence in the face of Granada's larger neighbours, the Christian kingdom of Castile and the Muslim Marinid state of Morocco, as well as an internal rebellion by his family's former allies, the Banu Ashqilula.

After he took the throne, he negotiated a treaty with Alfonso X of Castile, in which Castile agreed to end support for the Banu Ashqilula in exchange for payments. When Castile took the money but maintained its support for the Banu Ashqilula, Muhammad turned towards Abu Yusuf of the Marinids. The Marinids sent a successful expedition against Castile, but relations soured when the Marinids treated the Banu Ashqilula as Muhammad's equals. In 1279, through diplomatic manoeuvring, Muhammad regained Málaga, formerly the centre of Banu Ashqilula power. In 1280, his diplomacy backfired when Granada faced simultaneous attacks from Castile, the Marinids and the Banu Ashqilula. Attacked by his more powerful neighbours, Muhammad exploited the rift between Alfonso and his son Sancho, as well as receiving help from Volunteers of the Faith, soldiers recruited from North Africa. The threat subsided when Alfonso died in 1284 and Abu Yusuf in 1286; their successors (Sancho and Abu Yaqub, respectively) were preoccupied with domestic matters. In 1288 the Banu Ashqilula emigrated to North Africa at Abu Yaqub's invitation, removing Muhammad's biggest domestic concern. In 1292, Granada helped Castile take Tarifa from the Marinids on the understanding that the town would be traded to Granada, but Sancho reneged on the promise. Muhammad II then switched to the Marinid side, but a Granadan–Marinid attempt to retake Tarifa in 1294 failed. In 1295, Sancho died and was succeeded by Ferdinand IV, a minor. Granada took advantage by conducting a successful campaign against Castile, taking Quesada and Alcaudete. Muhammad also planned a joint offensive with Aragon against Castile, but he died in 1302 before the operation took place. (Full article...)

Seleucus VI Epiphanes Nicator (Ancient Greek: Σέλευκος Ἐπιφανής Νικάτωρ, romanized: Séleukos Epiphanís Nikátor; between 124 and 109 BC – 94 BC) was a Hellenistic Seleucid monarch who ruled Syria between 96 and 94 BC. He was the son of Antiochus VIII and his Ptolemaic Egyptian wife Tryphaena. Seleucus VI lived during a period of civil war between his father and his uncle Antiochus IX, which ended in 96 BC when Antiochus VIII was assassinated. Antiochus IX then occupied the capital Antioch while Seleucus VI established his power-base in western Cilicia and himself prepared for war. In 95 BC, Antiochus IX marched against his nephew, but lost the battle and was killed. Seleucus VI became the master of the capital but had to share Syria with his brother Demetrius III, based in Damascus, and his cousin, Antiochus IX's son Antiochus X.

According to the ancient historian Appian, Seleucus VI was a violent ruler. He taxed his dominions extensively to support his wars, and resisted allowing the cities a measure of autonomy, as had been the practice of former kings. His reign did not last long; in 94 BC, he was expelled from Antioch by Antiochus X, who followed him to the Cilician city of Mopsuestia. Seleucus took shelter in the city where his attempts to raise money led to riots that eventually claimed his life in 94 BC. Ancient traditions have different versions of his death, but he was most probably burned alive by the rioters. Following his demise, his brothers Antiochus XI and Philip I destroyed Mopsuestia as an act of revenge and their armies fought those of Antiochus X. (Full article...)

Edward III (13 November 1312 – 21 June 1377), also known as Edward of Windsor before his accession, was King of England from January 1327 until his death in 1377. He is noted for his military success and for restoring royal authority after the disastrous and unorthodox reign of his father, Edward II. Edward III transformed the Kingdom of England into one of the most formidable military powers in Europe. His fifty-year reign is one of the longest in English history, and saw vital developments in legislation and government, in particular the evolution of the English Parliament, as well as the ravages of the Black Death. He outlived his eldest son, Edward the Black Prince, and was succeeded by his grandson, Richard II.

Edward was crowned at age fourteen after his father was deposed by his mother, Isabella of France, and her lover, Roger Mortimer. At the age of seventeen, he led a successful coup d'état against Mortimer, the de facto ruler of the country, and began his personal reign. After a successful campaign in Scotland, he declared himself rightful heir to the French throne, starting the Hundred Years' War. Following some initial setbacks, this first phase of the war went exceptionally well for England, and would become known as the Edwardian War. Victories at Crécy and Poitiers led to the highly favourable Treaty of Brétigny, in which England made territorial gains, and Edward renounced his claim to the French throne. Edward's later years were marked by foreign policy failure and domestic strife, largely as a result of his increasing inactivity and poor health. (Full article...)

King Arthur (Welsh: Brenin Arthur, Cornish: Arthur Gernow, Breton: Roue Arzhur, French: Roi Arthur) is a legendary king of Britain, a hero of English mythology, and a central figure in the medieval literary tradition known as the Matter of Britain.

In Welsh sources, Arthur is portrayed as a leader of the post-Roman Britons in battles against Anglo-Saxon invaders of Britain in the late 5th and early 6th centuries. He first appears in two early medieval historical sources, the Annales Cambriae and the Historia Brittonum, but these date to 300 years after he is supposed to have lived, and most historians who study the period do not consider him a historical figure. His name also occurs in early Welsh poetic sources such as Y Gododdin. The character developed through Welsh mythology, appearing either as a great warrior defending Britain from human and supernatural enemies or as a magical figure of folklore, sometimes associated with the Welsh otherworld Annwn.

Æthelred, Lord of the Mercians (or Ealdorman Æthelred of Mercia; died 911) became ruler of English Mercia shortly after the death or disappearance of its last king, Ceolwulf II in 879. Æthelred's rule was confined to the western half, as eastern Mercia was then part of the Viking-ruled Danelaw. His ancestry is unknown. He was probably the leader of an unsuccessful Mercian invasion of Wales in 881, and soon afterwards he acknowledged the lordship of King Alfred the Great of Wessex. This alliance was cemented by the marriage of Æthelred to Alfred's daughter Æthelflæd.

In 886, Alfred took possession of London, which had suffered greatly from several Viking occupations. Alfred then handed London over to Æthelred, as it had traditionally been a Mercian town. In 892, the Vikings renewed their attacks, and the following year, Æthelred led an army of Mercians, West Saxons and Welsh to victory over a Viking army at the Battle of Buttington. He spent the next three years fighting them alongside Alfred's son, the future King Edward the Elder. At some time after 899 Æthelred's health may have declined, and Æthelflæd may have become the effective ruler of Mercia. (Full article...)

Abu al-Hajjaj Yusuf ibn Ismail (Arabic: أبو الحجاج يوسف بن إسماعيل; 29 June 1318 – 19 October 1354), known by the regnal name al-Muayyad billah (المؤيد بالله, "He who is aided by God"), was the seventh Nasrid ruler of the Emirate of Granada on the Iberian Peninsula. The third son of Ismail I (r. 1314–1322), he was Sultan between 1333 and 1354, after his brother Muhammad IV (r. 1325–1333) was assassinated.

Coming to the throne at age fifteen, he was initially treated as a minor and given only limited power by his ministers and his grandmother Fatima. In February 1334, his representatives secured a four-year peace treaty with Granada's neighbours Castile and the Marinid Sultanate. Aragon joined in the treaty in May. After gaining more control of the government, in 1338 or 1340 he expelled the Banu Abi al-Ula family, who had masterminded the murder of his brother and had been the leaders of the Volunteers of the Faith—North African soldiers who fought for Granada. After the treaty expired, he allied himself with Abu al-Hasan Ali (r. 1331–1348) of the Marinids against Alfonso XI of Castile (r. 1312–1350). After winning a major naval victory in April 1340, the Marinid–Granadan alliance was decisively defeated on 30 October in the disastrous Battle of Río Salado. In its aftermath, Yusuf was unable to prevent Castile from taking several Granadan castles and towns, including Alcalá de Benzaide, Locubín, Priego and Benamejí. In 1342–1344, Alfonso XI besieged the strategic port of Algeciras. Yusuf led his troops in diversionary raids into Castilian territory, and later engaged the besieging army, but the city fell in March 1344. A ten-year peace treaty with Castile followed.

Frederick III or Friedrich III (Friedrich Wilhelm Nikolaus Karl; 18 October 1831 – 15 June 1888) was German Emperor and King of Prussia for 99 days between March and June 1888, during the Year of the Three Emperors. Known informally as "Fritz", he was the only son of Emperor Wilhelm I and was raised in his family's tradition of military service. Following the unification of Germany in 1871 his father, then King of Prussia, became German Emperor. Upon Wilhelm's death at the age of ninety on 9 March 1888, the thrones passed to Frederick, who had been German Crown Prince for seventeen years and Crown Prince of Prussia for twenty-seven years. Frederick was suffering from cancer of the larynx when he died, aged fifty-six, following unsuccessful medical treatments for his condition.

Frederick married Victoria, Princess Royal, oldest child of Queen Victoria of the United Kingdom. The couple were well-matched; their shared liberal ideology led them to seek greater representation for commoners in the government. Despite his conservative militaristic family background, Frederick had developed liberal tendencies as a result of his ties with Britain and his studies at the University of Bonn. As crown prince, he often opposed the conservative German chancellor Otto von Bismarck, particularly in speaking out against Bismarck's policy of uniting Germany through force, and in urging that the power of the chancellorship be curbed. Liberals in both Germany and Britain hoped that as emperor, Frederick would move to liberalise the German Empire. (Full article...)

Ramesses VI Nebmaatre-Meryamun (sometimes written Ramses or Rameses, also known under his princely name of Amenherkhepshef C) was the fifth ruler of the Twentieth Dynasty of Egypt. He reigned for about eight years in the mid-to-late 12th century BC and was a son of Ramesses III and queen Iset Ta-Hemdjert. As a prince, he was known as Ramesses Amunherkhepeshef and held the titles of royal scribe and cavalry general. He was succeeded by his son, Ramesses VII Itamun, whom he had fathered with queen Nubkhesbed.

After the death of the ruling pharaoh, Ramesses V, who was the son of Ramesses VI's older brother, Ramesses IV, Ramesses VI ascended the throne. In the first two years after his coronation, Ramesses VI stopped frequent raids by Libyan or Egyptian marauders in Upper Egypt and buried his predecessor in what is now an unknown tomb of the Theban necropolis. Ramesses VI usurped KV9, a tomb in the Valley of the Kings planned by and for Ramesses V, and had it enlarged and redecorated for himself. The craftsmen's huts near the entrance of KV9 covered up the entrance to Tutankhamun's tomb, saving it from a wave of tomb robberies that occurred within 20 years of Ramesses VI's death. Ramesses VI may have planned and made six more tombs in the Valley of the Queens, none which are known today. (Full article...)

Wulfhere or Wulfar (died 675) was King of Mercia from 658 until 675 AD. He was the first Christian king of all of Mercia, though it is not known when or how he converted from Anglo-Saxon paganism. His accession marked the end of Oswiu of Northumbria's overlordship of southern England, and Wulfhere extended his influence over much of that region. His campaigns against the West Saxons led to Mercian control of much of the Thames valley. He conquered the Isle of Wight and the Meon valley and gave them to King Æthelwealh of the South Saxons. He also had influence in Surrey, Essex, and Kent. He married Eormenhild, the daughter of King Eorcenberht of Kent.

Wulfhere's father, Penda, was killed in 655 at the Battle of Winwaed, fighting against Oswiu of Northumbria. Penda's son Peada became king under Oswiu's overlordship but was murdered six months later. Wulfhere came to the throne when Mercian nobles organized a revolt against Northumbrian rule in 658 and drove out Oswiu's governors. (Full article...)

Edward VI (12 October 1537 – 6 July 1553) was King of England and Ireland from 28 January 1547 until his death in 1553. He was crowned on 20 February 1547 at the age of nine. The only surviving son of Henry VIII by his third wife, Jane Seymour, Edward was the first English monarch to be raised as a Protestant. During his reign, the realm was governed by a regency council because Edward never reached maturity. The council was first led by his uncle Edward Seymour, 1st Duke of Somerset (1547–1549), and then by John Dudley, 1st Duke of Northumberland (1550–1553).

Edward's reign was marked by economic problems and social unrest that in 1549 erupted into riot and rebellion. An expensive war with Scotland, at first successful, ended with military withdrawal from Scotland and Boulogne-sur-Mer in exchange for peace. The transformation of the Church of England into a recognisably Protestant body also occurred under Edward, who took great interest in religious matters. His father, Henry VIII, had severed the link between the English Church and Rome, but continued to uphold most Catholic doctrine and ceremony. It was during Edward's reign that Protestantism was established for the first time in England with reforms that included the abolition of clerical celibacy and the Mass, and the imposition of compulsory English in church services.

Edmund I or Eadmund I (920/921 – 26 May 946) was King of the English from 27 October 939 until his death. He was the elder son of King Edward the Elder and his third wife, Queen Eadgifu, and a grandson of King Alfred the Great. After Edward died in 924, he was succeeded by his eldest son, Edmund's half-brother Æthelstan. Edmund was crowned after Æthelstan died childless in 939. He had two sons, Eadwig and Edgar, by his first wife Ælfgifu, and none by his second wife Æthelflæd. His sons were young children when he was killed in a brawl with an outlaw at Pucklechurch in Gloucestershire, and he was succeeded by his younger brother Eadred, who died in 955 and was followed by Edmund's sons in succession.

Æthelstan had succeeded as the king of England south of the Humber and he became the first king of all England when he conquered Viking-ruled York in 927, but after his death Anlaf Guthfrithson was accepted as King of York and extended Viking rule to the Five Boroughs of north-east Mercia. Edmund was initially forced to accept the reverse, the first major setback for the West Saxon dynasty since Alfred's reign, but he was able to recover his position following Anlaf's death in 941. In 942 Edmund took back control of the Five Boroughs and in 944 he regained control over the whole of England when he expelled the Viking kings of York. Eadred had to deal with further revolts when he became king, and York was not finally conquered until 954. Æthelstan had achieved a dominant position over other British kings and Edmund maintained this, perhaps apart from Scotland. The north Welsh king Idwal Foel may have allied with the Vikings as he was killed by the English in 942. The British kingdom of Strathclyde may also have sided with the Vikings as Edmund ravaged it in 945 and then ceded it to Malcolm I of Scotland. Edmund also continued his brother's friendly relations with Continental rulers, several of whom were married to his half-sisters. (Full article...)

Wallis, Duchess of Windsor (born Bessie Wallis Warfield, later Spencer and then Simpson; June 19, 1896 – April 24, 1986) was an American socialite and wife of former king Edward VIII. Their intention to marry and her status as a divorcée caused a constitutional crisis that led to Edward's abdication.

Wallis grew up in Baltimore, Maryland. Her father died shortly after her birth, and she and her widowed mother were partly supported by their wealthier relatives. Her first marriage, to United States Navy officer Win Spencer, was punctuated by periods of separation and eventually ended in divorce. In 1931, during her second marriage, to Ernest Simpson, she met Edward, then Prince of Wales. Five years later, after Edward's accession as King of the United Kingdom, Wallis divorced Ernest to marry Edward. (Full article...)

Catherine de' Medici (Italian: Caterina de' Medici, pronounced [kateˈriːna de ˈmɛːditʃi]; French: Catherine de Médicis, pronounced [katʁin də medisis]; 13 April 1519 – 5 January 1589) was an Italian (Florentine) noblewoman born into the Medici family. She was Queen of France from 1547 to 1559 by marriage to King Henry II and the mother of French kings Francis II, Charles IX, and Henry III. The years during which her sons reigned have been called "the age of Catherine de' Medici" since she had extensive, if at times varying, influence on the political life of France.

Catherine was born in Florence to Lorenzo de' Medici, Duke of Urbino, and Madeleine de La Tour d'Auvergne. In 1533, at the age of 14, Catherine married Henry, the second son of King Francis I and Queen Claude of France, who would become Dauphin of France upon the death of his elder brother Francis in 1536. Catherine's marriage was arranged by her uncle Pope Clement VII. During his reign, Henry excluded Catherine from state affairs and instead showered favours on his chief mistress, Diane de Poitiers, who wielded much influence over him. Henry's death in 1559 thrust Catherine into the political arena as mother of the frail 15-year-old Francis II. When Francis II died in 1560, she became regent on behalf of her 10-year-old son Charles IX and was thus granted sweeping powers. After Charles died in 1574, Catherine played a key role in the reign of her third son, Henry III. He dispensed with her advice only in the last months of her life but outlived her by just seven months. (Full article...)
