Bolesław II of Masovia or Bolesław II of Płock (pl: Bolesław II mazowiecki (płocki); ca. 1253/58 – 20 April 1313), was a Polish prince member of the House of Piast, Duke of Masovia during 1262-1275 jointly with his brother, since 1275 sole ruler over Płock, since 1294 ruler over all Masovia and Duke of Kraków and Sandomierz during 1288-1289. In 1310 he gave to his sons the districts of Warsaw and Czersk.
He was the eldest son of Siemowit I of Masovia and Pereyaslava, a daughter of Prince Daniel of Halych.
Nothing is known from Bolesław II's first years, except that in 1262 he wasn't with his father and older brother Konrad II during the siege and battle of Jazdów, where Siemowit I was killed and Konrad II was captured by the Lithuanians. Because Bolesław II was too young to rule by himself, the regency was exercised by his mother Pereyaslava and his late father's ally, Bolesław the Pious, Duke of Greater Poland, until 1264, when his brother Konrad II was liberated and returned to assume the government.
When Bolesław II attained his majority in 1275, he demanded from his brother his part over their paternal inheritance. As a result, he received the western part of Masovia, with his capital in Płock. However he was not satisfied with this distribution, evidenced in his long-standing conflict with Konrad II; during this fight, Bolesław II did not hesistate to ask for the help of the murders of his father, the Lithuanians. The alliance between Bolesław II and Lithuania was strengthened in 1279 when he married with Gaudemantė, the daughter of Grand Duke Traidenis, who in her baptism took the name of Sophia.
Another ally of Bolesław II was his cousin Władysław I the Elbow-high, who was then Duke of Kujawy. The war between Bolesław II and Konrad exented during the second half of the 1270s and the first half of the 1280s and didn't bring any real benefits for any of the parties, only caused destruction in extended parts of Masovia.
