Capetian House of Anjou
The Capetian House of Anjou, or House of Anjou-Sicily was a royal house and cadet branch of the Capetian dynasty. It is one of three separate royal houses referred to as Angevin, meaning "from Anjou" in France. Founded by Charles I of Anjou, the youngest son of Louis VIII of France, the Capetian king first ruled the Kingdom of Sicily during the 13th century. The War of the Sicilian Vespers later forced him out of the island of Sicily, leaving him with the southern half of the Italian Peninsula, known as the Kingdom of Naples. The house and its various branches would go on to influence much of the history of Southern and Central Europe during the Middle Ages until it became extinct in 1435.
Historically, the house ruled the Counties of Anjou, Maine, Touraine, Provence and Forcalquier; the Principalities of Achaea and Taranto; and the Kingdoms of Sicily, Naples, Hungary, Croatia, Albania and Poland.
Rise of Charles I and his sons
A younger son of the House of Capet king Louis VIII of France the Lion, Charles was first given a noble title by his brother, Louis IX of France who succeeded to the French throne in 1226. Charles was named Count of Anjou and Maine; the feudal County of Anjou was a western vassal state of the Kingdom of France, which the Capetians had wrested from the House of Plantagenet only a few decades earlier. Charles married an heiress of the County of Provence named Beatrice of Provence. She was a member of the House of Barcelona; this meant Charles' holdings were growing as Count of Provence. After fighting in the Seventh Crusade, Charles was offered the Kingdom of Sicily by Pope Clement IV. At the time this included not only the island of Sicily but also the southern half of the Italian Peninsula. Pope Clement IV offered it to Charles because of a conflict between the papacy and the Holy Roman Empire, and the latter was represented by the ruling House of Hohenstaufen.It was at the Battle of Benevento that the Guelph Capetians gained the Sicilian kingdom from the Ghibelline Swabians, this was cemented after victory at Tagliacozzo. In keeping with the political landscape of the period, Charles is described by scholars as shrewd, energetic and highly ambitious. He signed the Treaty of Viterbo in 1267 with Baldwin II of Courtenay and William II of Villehardouin, the political alliance gave many of the rights of the Latin Empire to Charles and a marriage alliance for his daughter Beatrice of Sicily. The Byzantines had taken back the city of Constantinople in 1261 and this was a plan to take it back from Michael VIII Palaiologos. It also recognised Charles' possession of Corfu and cities in the Balkans such as Durazzo, as well as giving him suzerainty over the Principality of Achaea and sovereignty of the Aegean islands aside from those already held by the Republic of Venice. For a while Charles was preoccupied helping his French brother in the unsuccessful Eighth Crusade on Tunis. After this he once again focused on Constantinople, but his fleet was wrecked in a freak storm off the coast of Trapani. With the elevation of Pope Gregory X, there was a truce between Charles and Michael in the form of the Council of Lyons, as Christians focused on improving ecumenical relations, with hopes of regaining the Kingdom of Jerusalem back from the Muslims.
Charles had fully solidified his rule over Durazzo by 1272, creating a small Kingdom of Albania for himself, out of previously Despotate of Epirus territory; he was well received by local chiefs.
Charles's regime was driven out of Sicily after Sicilian Vespers in 1282, but his house ruled Naples until 1435, when René of Anjou inherited the kingdom.
Charles II and division of the inheritance
This House of Anjou included the branches of Anjou-Hungary, which ruled Hungary and Poland, Anjou-Taranto, which ruled the remnants of the Latin Empire and Anjou-Durazzo, which ruled Naples and Hungary.The senior line of the House of Anjou-Durazzo became extinct in the male line with the death of King Ladislaus of Naples in 1414, and totally extinct with the death of his sister Joanna II in 1435.
Cadet branches
Hungary
During the Middle Ages, there were several marriages between the Árpád dynasty and the House of Capet. Charles I, founder of the House of Anjou-Sicily, with his first wife, Beatrice of Provence fathered his eldest son, Charles II of Naples.. In 1270, Charles II married Mary of Hungary, daughter of Stephen V of Hungary and Elizabeth the Cuman. They had fourteen children which provided the House of Anjou-Sicily with a secure position in Naples.The childless Ladislaus IV of Hungary, was succeeded by Andrew III as King of Hungary. He was the son of Stephen the Posthumous, considered by Stephen's much older half-brothers a bastard son of infidelity. For this reason, after the death of Ladislaus IV. some of the Árpád dynasty's cognates sought the family as extinct. In Naples, Charles Martel of Anjou, the eldest son of Mary of Hungary announced his claim to the Hungarian crown, backed by his mother, and the Pope. He started to style himself King of Hungary, but he never managed to gain enough support from the Hungarian magnates to realize his claim.
With Andrew III's death, the "last golden branch" of the tree of King Saint Stephen's family ended. The Hungarian diet was determined to keep the blood of Saint Stephen on the throne in the maternal line at least. In the upcoming years, a civil war followed between various claimants to the throne. After the short period of rule of Wenceslaus of Bohemia, and Otto of Bavaria the civil war ended with Charles Robert's victory, the son of Charles Martel of Anjou, but he was forced to continue fighting against the powerful Hungarian lords up to the early 1320s.

The three surviving sons of Charles Robert were Louis I of Hungary, Andrew, Duke of Calabria, and Stephen, Duke of Slavonia. Louis I had only two surviving daughters, Mary of Hungary, who married the future Holy Roman Emperor Sigismund of Luxembourg, and Hedwig of Poland, who was given in marriage to the Grand Duke of Lithuania Władysław II Jagiełło, the future King of Poland. After Louis I's death without male heirs, Mary's husband, Sigismund of Luxembourg managed to be accepted as Mary's co-ruler, by the Hungarian lords. When the queen died the Hungarian crown passed over to the House of Luxembourg.
In 1333, the six years old second son of Charles Robert, Andrew was taken to the court of Naples by his father for dynastic purposes, who put him under guardianship of Robert the Wise. Andrew was betrothed in 1334 to his cousin Joanna, granddaughter and heiress apparent of King Robert of Naples; Andrew's father was a fraternal nephew of King Robert. At the age of 15 he married Joanna I of Naples. After the death of Robert, the King of Naples, Andrew became a victim of power clashes in the court of Naples.
Robert's claim to the throne was rather tenuous and did not follow primogeniture. Andrew's grandfather, Charles Martel of Anjou, had died young; therefore, the throne should have passed to Andrew's father. However, due to fears of impending invasion from Sicily, it was felt that a seven-year-old heir was too risky and would not be able to hold off invasions. The throne was offered to the next son of Charles II of Naples, Louis, but he refused on religious grounds, and it thus passed to Robert. To recompense Andrew's father, Charles II decided to assign him the claim to Hungary.
Stephen of Anjou, Duke of Slavonia, the third surviving son of Charles Robert, died before his older brother. For this reason, he had no chance to take over the rule neither in Hungary, nor in Poland. In 1350, he married Margaret of Bavaria. His marriage with a German princess made him unpopular in Poland. The Polish noblemen acknowledged Louis as Casimir III's sole heir in July 1351 only after he had promised that he would not allow Stephen to participate in the government of Poland. Margaret gave birth to a daughter Elizabeth, and a son John, who inherited Croatia, Dalmatia and Slavonia from his father, but he was still a child when he died in 1360.
On the death of Louis I of Hungary, Charles III of Naples, son of Louis of Durazzo, the great-grandson of Charles II of Naples and Mary of Hungary, claimed the Hungarian throne as the senior Angevin male, and ousted Louis' daughter Mary of Hungary in December 1385. It was not difficult for him to reach the power, as he counted with the support of several Croatian lords, and many contacts which he made during his period as Duke of Croatia and Dalmatia. However, Elizabeth of Bosnia, widow of Louis and mother of Mary, arranged to have Charles assassinated on 7 February 1386. He died of wounds at Visegrád on 24 February. His son, Ladislaus of Naples would try to obtain the crown of Hungary in the future, but never reached his goal.
Poland
In 1355, the last Piast king of Poland, Casimir III, designated his sororal nephew, the Angevin king Louis I of Hungary, as his heir presumptive by the Privilege of Buda. Upon the death of Casimir, who left no legitimate sons, Louis ascended the Polish throne virtually unopposed. The Polish nobility welcomed his accession, rightly believing that Louis would be an absentee king who would not take much interest in Polish affairs. He sent his mother Elizabeth, sister of Casimir III, to govern Poland as regent. Louis probably considered himself first and foremost king of Hungary; he visited his northern kingdom three times and spent there a couple of months altogether. Negotiations with the Polish nobility frequently took place in Hungary. Hungarians themselves were unpopular in Poland, as was the king's Polish mother who governed the kingdom. In 1376, circa 160 Hungarians in her retinue were massacred in Kraków and the queen returned to Hungary disgraced. Louis replaced her with their relative, Vladislaus II of Opole.The Hungarian-Polish union fell apart after Louis died in 1382. The dissatisfied Polish nobles demanded that his successor in Hungary, Mary, move to Kraków and reign over Hungary and Poland from there. Mary's mother, Elizabeth of Bosnia, knew that the lack of supporters would render her influence at least as restricted as that of her mother-in-law and refused to move. She abandoned the idea of attempting to subdue the Polish nobility by force and agreed to send her younger surviving daughter, Hedwig, to be crowned as Louis' successor in Poland.
Hedvig was crowned "king" in Poland's capital, Kraków, on 16 October 1384. Her coronation either reflected the Polish nobility's opposition to her intended husband, William, becoming king without further negotiation, or simply emphasized her status as queen regnant. With her mother's consent, Jadwiga's advisors opened negotiations with Jogaila, Grand Duke of Lithuania, who was still a pagan, concerning his potential marriage to Jadwiga. Jogaila signed the Union of Krewo, pledging to convert to Roman Catholicism and to promote his pagan subjects' conversion. Jogaila, who took the baptismal name Władysław, married Jadwiga on 15 February 1386. Jogaila, now in Polish styled Władysław Jagiełło, was crowned King of Poland on 4 March 1386. As Jadwiga's co-ruler, Jagiełło worked closely with his wife. Hedvig was childless for over a decade. She became pregnant in late 1398 or early 1399. A newborn princess named Elizabeth Bonifacia was delivered on 22 June 1399 at Wawel Castle. However, the infant died after only three weeks, on 13 July 1399. Jadwiga, too, was on her deathbed. She died on 17 July 1399, four days after her newborn daughter. Thus, the Polish throne went over to the Jagiellonian dynasty of Lithuanian origin. The union of Poland and Lithuania was a decisive moment in the histories of both countries; it marked a beginning of the four centuries of shared history. By 1569, the Polish–Lithuanian union grew into a new state, the Polish–Lithuanian Commonwealth, and lasted until the Third Partition in 1795.
