This article's aim is to gather examples of transcontinentalroyal intermarriages, that is, royal intermarriage between royal families originating from different continents. One of the best-known instances of transcontinental royal intermarriage is the one between Alexander the Great, king of Macedon, and his three Persian wives, Roxana, Stateira and Parysatis.
Around 732, to solidify an alliance with Khazaria, the future emperor Constantine V married Tzitzak, daughter of khagan Bihar. Tzitzak was later renamed "Irene". The marriage produced Byzantine emperor Leo IV, who was given the epithet "the Khazar" referencing his maternal descent.[7][9]
Due to the closeness of the empire with the two realms, Byzantine royals often married with Armenian and Georgian dynasties. Here follows a list of documented marriages:
Around 1265, Byzantine Emperor Michael VIII attempted to start diplomatic relationships with the Mongol Ilkhanate. A marriage was combined between Ilkhan Hulagu, and Michael's illegitimate daughter, Maria Palaiologina. Maria left Costantinople in 1265, but when she arrived in Caesarea she was informed that Hulagu had died, so it was decided for her to marry Hulagu's son, Abaqa. The Mongols called Maria "Despina Khatun". The marriage produced a daughter, Theodora Ara Qutlugh.[16][17][18][19]
Michael VIII also tried to form an alliance with the Golden Horde. In 1266, he gave another illegitimate daughter, Epuhrosyne Palaiologina, in marriage to the khanNogai. There are no known children resulting from this marriage.[20]
In a negotiation between Richard the Lionheart and Saladin during the third crusade, it was proposed to arrange a marriage between al-Adil, Saladin's brother, and either Richard's sister Joan or his niece Eleanor. The arrangement however failed for religious reasons.[21]
Around 1238, Béla IV of Hungary arranged a marriage between his son, future Stephen V, and Elizabeth, the daughter of a Cuman leader whom he had invited to settle in the plains along the river Tisza. This leader is either khan Köten or a man named Seyhan. The marriage resulted in 4 daughters and 2 sons, among whom there is Laudislaus IV, who succeeded his father, and who was nicknamed "the Cuman" for his mother's origins.[22][23][24][25]
In 1315, Yury, prince of Moscow, sealed an alliance with khan Uzbeg of the Golden Horde by marrying his sister Konchaka. Konchaka then converted to orthodoxy and was renamed "Agafiia". She was imprisoned in a war to take the principality of Vladimir and died before she could give Yury any sons.[26][27]
