Soběslav II, called Prince of the Peasants or King of the Peasants, was the Duke of Bohemia from 1173 to 1178. He was the second son of Soběslav I. Supported by neither nobles nor emperor, he was backed solely by the lowest classes.
Soběslav granted a charter to the town of Prague, but he entered into a fight with Henry II, Duke of Austria, in 1175. In summer 1176, an army led by Duke Conrad Otto of Znojmo devastated the country to the north of the Danube. Churches and monasteries were attacked and Pope Alexander III excommunicated the duke. Barbarossa intervened in 1177 and recognised Frederick as duke. By 1179, Soběslav was removed and he died in "some part of a foreign land" on 29 January 1180 without heirs from his union with Elisabeth (d.1209), daughter of Mieszko III of Poland.
