The son of Bretislaus, Vratislaus II, supported Henry against the Pope, anti-kings, and rebellions in Saxony in his long reign. The Bohemian troops showed conspicuous bravery and, in 1083, he entered Rome with Henry and their armed forces. Henry gave Vratislaus a lifetime appointment as the first King of Bohemia in 1085 out of gratitude. For his successor Bretislaus II foreign policy was largely concerned with the Silesian conflict, when the Poles did not pay a fee for areas once resigned by Bretislaus I.
