(Saint) László, who was king of Hungary and Croatia from 1077 to 1095, was born as the second son of the Árpád house. His father was King Béla I of Hungary and his mother was Princess Adelaide of Poland. During the reign of King László, he carried out significant territorial expansions and consolidated the internal order of the kingdom. According to legend, he is known for his fight against a "kun" (Turkish nomadic raider) who kidnapped a Hungarian girl. After the death of his brother Géza, he was crowned king. King László sided with the Pope in the investment dispute, although he was in conflict with the Holy Roman Emperor IV. He also reconciled with Henrik. In 1085, he canonized the first Hungarian saints, including King István I and Duke Imre. King László introduced strict laws that punished those who violated property rights with death or mutilation. In 1091, he almost completely invaded Croatia, which marked the beginning of the period of expansion of the medieval Kingdom of Hungary. His victories over the Pechenegs and Kunks ensured the security of the eastern borders of his kingdom for about 150 years. King László died suddenly while preparing for the First Crusade. As the ideal Hungarian knight, the nation revered him as a saint, even before his official canonization. After his death, he was canonized in 1192, his feast day is June 27.
