Boleslaus II was a duke and king of Poland 1058-1079 (crowned 1076). In Polish he is known as Bolesław Śmiały (the Bold), Szczodry (the Generous), or Okrutny (the Cruel).
He supported pope Gregory VII in his struggle with the Emperor, but had the Bishop of Krakow St. Stanislaus put to death as a traitor. The king was forced into exile and Ladislaus Herman of Poland, 1079-1102, became duke of Poland. After him, two brothers, Zbigniew and Boleslaus, ruled jointly from 1102-1107.
