Ladislaus I or
Ladislas I, also
Saint Ladislaus or
Saint Ladislas (; ; ; 1040 – 29 July 1095) was
King of Hungary from 1077 and
King of Croatia from 1091. He was the second son of King
Béla I of Hungary. After Béla's death in 1063, Ladislaus and his elder brother,
Géza, acknowledged their cousin,
Solomon as the lawful king in exchange for receiving
their father's former duchy, which included one-third of the Kingdom of Hungary. Géza and Ladislaus cooperated with Solomon during the next decade. Ladislaus's
most popular legend, which narrates his fight with a "Cuman" (a
Turkic nomad marauder) who abducted a Hungarian girl, is connected to this period. Géza's and Ladislaus's relationship with Solomon deteriorated in the early 1070s. They rebelled against Solomon, and Géza was proclaimed king in 1074, but Solomon maintained control of the western regions of his kingdom. During Géza's reign, Ladislaus was his brother's most influential adviser.
