From Encyclopedia Britannica Online, article titled "Boleslaw III:"

"byname BOLESLAW THE WRY-MOUTHED, POLISH BOLESLAW KRZYWOUSTY, prince of Poland who introduced into his country the senioriate system, by which the eldest son received the major part of the royal inheritance. He also converted the Pomeranians to Christianity.

"Son of Wladyslaw I Herman, ruler of Poland, and Judith of Bohemia, Boleslaw III and his illegitimate elder half brother, Zbigniew, each ruled a Polish province during their father's lifetime. Boleslaw III succeeded to his father's princely title (no Polish ruler assumed the title of king from 1082 to 1296) in 1102 and spent the next several years fighting Zbigniew for control of the country. After repelling an invasion of Silesia (1109) by the German king Henry V, Boleslaw, who had exiled Zbigniew in 1107, recalled him in 1112; soon, however, he accused Zbigniew of treason and had him blinded. Zbigniew died soon thereafter.

"For the next 22 years (1113-35) Boleslaw sought control of Poland's former province of Pomerania; he conquered Eastern Pomerania in 1122 but did not secure Western Pomerania until he had sworn fealty to the Holy Roman emperor Lothair II in 1135. Boleslaw sent missionaries into Pomerania, converted the pagan tribes there to Christianity, and integrated the people into the Polish state. He then enacted legislation to secure Pomerania and Silesia for his eldest son and lesser provinces for his younger sons. The senioriate system, a halfway measure between primogeniture and equal distribution among all male heirs, was devised to satisfy all princely heirs; yet it caused dissension and eventually led to the disintegration of the state."
