However, after the death in 1247 of Vladislaus, Margrave of Moravia, Ottokar's older brother and the heir of Bohemia, Ottokar became the heir. According to popular oral tradition, Ottokar was profoundly shocked by his brother's death and did not involve himself in politics, becoming focused on hunting and drinking. In 1248 he was enticed by discontented nobles to lead a rebellion against his father, King Wenceslaus. During this rebellion he received the nickname "the younger King" (mlad í král).
