Among those who did supported Henry II's claims, however, were Duke Mieszko I of Poland and Duke Boleslaus II of Bohemia.

Mieszko I, then a pagan, would married Boleslaus I's Christian daughter Dobrawa in 965, and would convert to Christianity in 966, bringing Poland closer to the Christian states of Bohemia and the Empire.

When Wenceslaus I was assassinated in 935, his brother Boleslaus I succeeded him as Duke and refused to continue paying the annual tribute to Germany.

Following the initial invasion, the conflict deteriorated into a series of border raids which lasted until 950 when Otto I and Boleslaus I signed a peace treaty.
