Bretislaus had to secure his duchy by force of arms. By Christmas 1193, he was keeping court at Prague. In 1195, he drove Vladislaus out of Moravia and installed one of his supporters in the march. Bretislaus also took part in an Imperial campaign in Meissen, where his army plundered the churches. To make amends, he planned to take part in the German Crusade of 1197, decided on at the diet of Worms of December 1195, but due to his prolonged illness it was never actualised. When Ottokar marched against Prague, Henry Bretislaus proceeded to the Imperial Palace in Eger (Cheb), where he died on 15 or 19 June 1197. He is buried in the Doksany monastery church.
