The Capetian dynasty, also known as the "House of France", is a dynasty of European origin, and a branch of the Robertians and the Karlings. It is among the largest and oldest royal houses in Europe and the world, and consists of Hugh Capet, the founder of the dynasty, and his male-line descendants, who ruled in France without interruption from 987 to 1792, and again from 1814 to 1848. The senior line ruled in France as the House of Capet from the election of Hugh Capet in 987 until the death of Charles IV in 1328. That line was succeeded by cadet branches, the Houses of Valois and then Bourbon, which ruled without interruption until the French Revolution abolished the monarchy in 1792. The Bourbons were restored in 1814 in the aftermath of Napoleon's defeat, but had to vacate the throne again in 1830 in favour of the last Capetian monarch of France, Louis Philippe I, who belonged to the House of Orléans. Cadet branches of the Capetian House of Bourbon are still reigning over Spain and Luxembourg.
John IV Doukas Laskaris was emperor of Nicaea from August 16, 1258, to December 25, 1261. This empire was one of the Greek states formed from the remaining fragments of the Byzantine Empire, after the capture of Constantinople by Roman Catholics during the Fourth Crusade in 1204.
Baldwin II, also known as Baldwin of Courtenay, was the last Latin Emperor ruling from Constantinople.
The Latin Empire, also referred to as the Latin Empire of Constantinople, was a feudal Crusader state founded by the leaders of the Fourth Crusade on lands captured from the Byzantine Empire. The Latin Empire was intended to replace the Byzantine Empire as the Western-recognized Roman Empire in the east, with a Catholic emperor enthroned in place of the Eastern Orthodox Roman emperors. The main objective of the Latin Empire was planned by Venice, which promoted the creation of this state for their self-benefit.
The Empire of Nicaea or the Nicene Empire was the largest of the three Byzantine Greek rump states founded by the aristocracy of the Byzantine Empire that fled when Constantinople was occupied by Western European and Venetian armed forces during the Fourth Crusade, a military event known as the Sack of Constantinople. Like the other Byzantine rump states that formed due to the 1204 fracturing of the empire, such as the Empire of Trebizond and the Despotate of Epirus, it was a continuation of the eastern half of the Roman Empire that survived well into the medieval period. A fourth state, known in historiography as the Latin Empire, was established by an army of Crusaders and the Republic of Venice after the capture of Constantinople and the surrounding environs.
The Principality of Achaea or Principality of Morea was one of the vassal states of the Latin Empire, which replaced the Byzantine Empire after the capture of Constantinople during the Fourth Crusade. It became a vassal of the Kingdom of Thessalonica, along with the Duchy of Athens, until Thessalonica was captured by Theodore, the despot of Epirus, in 1224. After this, Achaea became for a while the dominant power in Greece.
Charles of Valois, the fourth son of King Philip III of France and Isabella of Aragon, was a member of the House of Capet and founder of the House of Valois, whose rule over France would start in 1328.
Philip I of Taranto, of the Angevin house, was titular Latin Emperor of Constantinople by right of his wife Catherine of Valois–Courtenay, Despot of Romania, King of Albania, Prince of Achaea and Taranto.
The King of Thessalonica was the ruler of the Kingdom of Thessalonica, one of the crusader states founded in Greece in the aftermath of the Fourth Crusade (1202–1204). The King of Thessalonica was not an independent ruler; the Kingdom of Thessalonica was one of several vassal states created by the crusaders, subservient to the new Latin Empire of Constantinople, which had supplanted the Byzantine Empire.
Philip, also Philip of Courtenay, held the title of Latin Emperor of Constantinople from 1273–1283, although Constantinople had been reinstated since 1261 AD to the Byzantine Empire; he lived in exile and only held authority over Crusader States in Greece. He was born in Constantinople, the son of Baldwin II of Constantinople and Marie of Brienne.
Robert II of Taranto, of the Angevin family, Prince of Taranto (1331–1346), King of Albania (1331–1364), Prince of Achaea (1332–1346), and titular Latin Emperor.
Catherine II, also Catherine of Valois or Catherine of Taranto, was the recognised Latin Empress of Constantinople from 1307–1346, although she lived in exile and only had authority over Crusader States in Greece. She was Princess consort of Achaea and Taranto, and also regent of Achaea from 1332–1341, and Governor of Cephalonia from 1341–1346.
Catherine I, also Catherine of Courtenay, was the recognised Latin Empress of Constantinople from 1283 to 1307, although she lived in exile and only held authority over Crusader States in Greece. In 1301, she became the second wife of Charles of Valois, by whom she had one son and three daughters; the eldest of these, Catherine II of Valois, Princess of Achaea succeeded her as titular empress.
The Treaty of Viterbo was a pair of agreements made by Charles I of Sicily with Baldwin II of Constantinople and William II Villehardouin, Prince of Achaea, on 24 and 27 May 1267, which transferred much of the rights to the defunct Latin Empire from Baldwin to Charles.
The Capetian House of Anjou, or House of Anjou-Sicily, or House of Anjou-Naples 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, which left him with the southern half of the Italian Peninsula, 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.
Marie of Brienne was Latin Empress as the wife of Baldwin II of Courtenay. She served as regent during the absence of Baldwin II twice: in 1237–1239, and in 1243–1257.
Marie of Bourbon was the sovereign baroness of Vostitsa in 1359-1370. She was princess consort of Achaea and titular Latin empress consort by marriage to Robert of Taranto, Prince of Achaea and titular Latin Emperor of Constantinople. Upon the death of Robert in 1364, she became princess regnant of Achaea until her death.
Philippe de Toucy was a French Crusader nobleman and Bailli of the Latin Empire.
