Bolko I of Opole

Bolko I of Opole (before 1258–1313), third son of Vladislaus I of Opole, ruled Opole from 1282, initially jointly with his brother Casimir, who took Bytom in 1284. An ally of Henry IV Probus of Wrocław, he was captured fighting at Siewierz in 1289 and ransomed a year later by Władysław I the Elbow-high.

In 1291 he did homage to Wenceslaus II of Bohemia, attended the king's coronations in 1297 and 1300, and was made starosta of Kraków. He died in 1313.
