Born in Nuremberg, Sigismund was a son of the emperor Charles IV and Elizabeth of Pomerania, daughter of Bogislaw V of Pomerania. In 1374 was betrothed to Mary, eldest surviving daughter of king Louis I of Hungary and Poland, who intended Mary to succeed him in the hereditary kingdom of Poland with her future husband as was the custom of the time. Sigismund became margrave of Brandenburg on his father's death in 1378. Sent to the Hungarian court, Sigismund became thoroughly Magyarized and entirely devoted to his adopted country.

In 1381, the then 13-year-old Sigismund was sent to Krakow by his eldest brother and guardian king Venceslaus IV of Bohemia, to learn Polish and to become acquainted with the land and its people. King Venceslaus also gave him Neumark to facilitate communication between Brandenburg and Poland. Because of his intrigues, Sigismund was expelled from Poland, which was then given to Mary's younger sister Jadwiga I of Poland, who married Jogaila of Lithuania. When an opposing candidate for the Árpád throne appeared, Sigismund fled, leaving his wife Mary and her mother, widow of King Louis, Elisabeth of Bosnia (Elizabeta Kotromanic) at the mercy of conspirators. Years of civil war followed.

Ladislaus I, or László was a king of the Kingdom of Hungary, 1077–1095 A.D. He was the son of Bela I, king of Hungary, and a Polish princess (Richeza - Rixa or Adelaida). His maternal grandparents were Polish king Mieszko II Lambert and Richensa of Lotharingia. He was born in Poland, where his father had sought refuge, and named according to his mother's kin's Slavic traditions (thus he brought the name Laszlo to yet increasing Hungarian use) - but was recalled by his father's elder brother Andrew I to Hungary and brought up there. He succeeded to the throne on the death of his brother Geza in 1077, as the eldest member of the royal family, and speedily won for himself a reputation scarcely inferior to that of Stephen I, by nationalizing Christianity and laying the foundations of Hungary's political greatness. Recognizing that the Holy Roman Empire was a natural enemy of the Kingdom of Hungary, Ladislaus formed a close alliance with the pope and other enemies of Henry IV, Holy Roman Emperor, including the anti-emperor Rudolph of Swabia and his chief supporter Welf, duke of Bavaria. He married Rudolph's daughter Adelaide, and she bore him one son and three daughters. His daughter Piroska of Hungary, married the Byzantine emperor John II Comnenus.
