due to otto's early death in 1002, his "renovatio" policies were not fully realized. king henry ii, otto's successor, changed the empire's policies. bolesław supported henry's rival, margrave eckard i of meissen, expanded the polish realm into the march of lusatia and the milceni lands, and also took the bohemian throne at prague, interfering with henry's interests. during a meeting with henry ii in merseburg, bolesław was attacked by henry's men and narrowly escaped with his life. as a consequence, the excellent relations between the empire and poland marked by the congress of gniezno turned into a state of hostility that soon emerged into a german-polish war which finally ended with the 1018 peace of bautzen.
