After his father's death in 1356, Bolko III and his brothers
Władysław Opolczyk and
Henry inherited
Opole as co-rulers; however, the full government was held by the oldest brother, Władysław Opolczyk. The independent rule of Bolko III began only around 1375, when he inherited
Strzelce after the death of his uncle
Albert without male issue. During his reign, he didn't play any political role. Bolko III spent much of his time at the courts of
King Charles in
Prague and
King Louis I in
Buda. In 1355, Bolko III, with several other Silesian Dukes, went to
Italy with King Charles of Bohemia, who came to
Rome for his coronation as
Holy Roman Emperor; ten years later, in 1365, he made a journey from
Luxembourg to
Avignon, and in 1377, together with King Louis I of Hungary and Władysław Opolczyk, he made a military expedition to
Bełz. Bolko III died on 21 September 1382 and was buried in the
Franciscan chapel of St. Anna in
Opole. Upon his death, his title passed to his four sons as co-rulers. Because his sons were minors, their guardianship was held by his uncle
Władysław Opolczyk. ==Marriage and issue==
