Supported by neither noblesse nor emperor, he was backed solely by the lowest classes. In 1172, Frederick, son of Ladislaus II, succeeded his abdicating father. Frederick Barbarossa, the Holy Roman Emperor, held a diet at Hermsdorf in September 1173 and deposed Frederick, nominating Oldrich, son of Sobeslav I. Oldrich immediately abdicated in favour of his elder brother Sobeslav II. Sobeslav had been imprisoned since 1161. Sobeslav 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 the 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.
