By 1322, relations between Bolesław and his younger brother Henry VI began to deteriorate. Henry refused to support the aggressive politics of his brother when he signed a peace treaty with Konrad of Oleśnica regarding the possession of Wrocław (Breslau). Bolesław offered to exchange his district of Legnica (Liegnitz) for Wrocław (Breslau). Henry VI refused, and the war between the brothers was imminent. Henry established contacts with the new King of Poland Władysław I Łokietek, promised him homage and was named his heir in exchange for aid. Władysław declined the offer because he feared a direct confrontation with the Kingdom of Bohemia. Henry then asked the help of Emperor Louis IV. On 20 April 1324, the Duke of Wrocław declared himself a vassal of the Empire. In return, Louis IV guaranteed the succession of Henry VI's lands to his daughters, prompting Bolesław to attack. Wrocław's defenses held, and Henry VI maintained control.
