). The following year, Henry III invaded again, skirted the border defences and laid siege to Bretislav in Prague. Forced by a mutiny among his nobles and betrayed by Bishop Šebíř of Prague, Bretislav had to renounce all of his conquests save for Moravia and recognize Henry III as his sovereign. In 1042, Emperor Henry III granted Bretislav Silesia as a lien.
In 1047, Emperor Henry III negotiated a peace treaty between Bretislav and the Poles. This pact worked in Bretislav's favour, as the Polish ruler swore never again to attack Bohemia in return for an annual subsidy to Gniezno.

through a marriage to Judith in 1020. Judith was a desirable bride, but
Oldřich of Bohemia had only one son, Bretislav, and he was of illegitimate birth, thus complicating the prospect of a marriage with the high-born Judith. Bretislav solved the problem by kidnapping Judith from a monastery in Schweinfurt. He was never punished for this crime, and he married Judith some time later. Their first son
Spytihněv was born after almost ten years, which led to the hypothesis that the kidnapping happened in 1029, although Judith may have given birth to daughters before her first son. In all, there were five sons from the marriage that survived into adulthood:
