Bolesław II of Masovia

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, after 1275 sole ruler over Płock, after 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. Also High duke of Poland twice (1288, 1289).

Life

Early years He was younger son of Siemowit I of Masovia and Pereyaslava, a Rus' princess, who was according to some historians a daughter of Prince Daniel of Halych or according to others his distant relative. He was born around 1253-1258.

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.

Duke of Płock

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 hesitate to ask for the help from the murderers of his father, the Lithuanians. The alliance between Bolesław II and Lithuania was strengthened in 1279 when he married 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 during the second half of the 1270s and the first half of the 1280s didn't benefit any party, only causing destruction in extended parts of Masovia.

Death of Leszek II the Black. Fighting for Kraków and Sandomierz

On 30 September 1288 Leszek II the Black died childless. Part of the local nobility, led by Paweł of Przemankowo, Bishop of Kraków and the Topór family supported the succession of Bolesław II.

However, he wasn't the only candidate for the Seniorate. Henryk IV Probus, Duke of Wrocław, also advanced his claims. At first, it seemed that Bolesław II was able to master Lesser Poland without obstacles, as his troops in 1288 captured Kraków and Sandomierz. However, later in the same year he was expelled from Kraków by the troops of Henryk IV Probus, who gained the decisive favor of the castellan Sulk the Bear (pl: Sułk z Niedźwiedzia), who opened the gates of Wawel Castle to him. After this victory, Henryk IV Probus returned to Wrocław, and Bolesław II managed to say in Sandomierz. In early February 1289 a coalition of Piast princes (Henry III of Głogów, Przemko of Ścinawa and Bolko I of Opole) organized an expedition to Kraków with the purpose of consolidating the rule of Henryk IV Probus. At the sime time Bolesław II, who still wanted to recover Kraków, organized a coalition with Władysław I the Elbow-high and Casimir II of Łęczyca, Unexpectedly, he also received the support of his brother Konrad II and Kievan Rus' troops. In this way, Bolesław II was able to organized a powerful army with the main objective of reconquering the Seniorate. The army of Henryk IV Probus withdrew from Kraków, and on 26 February the bloody Battle of Siewierz took place, which ended with the defeat of Henryk IV's allies; during the fight, was killed Przemko of Ścinawa and Bolko I of Opole was captured. After the battle, Bolesław II occupied Kraków, where he triumphantly entered in the summer of 1289. Shortly after, he gave Sandomierz to his brother Konrad II as they had previously accorded in exchange of his military support. This action caused outrage among the Lesser Poland nobility (accustomed to see the Duke of Kraków reign over Sandomierz), who utterly refused to recognize Bolesław II as their ruler, and proclaimed Władysław I the Elbow-high as the new Duke of Kraków. For unknown reasons, Bolesław II refused to fight and retreated to his domains in Płock, and in August 1289 Władysław I the Elbow-high was in turn expelled by Henryk IV Probus, who became in the new ruler over Kraków and Sandomierz.

Bolesław II died on 20 April 1313 in Wyszogród and was buried at Płock Cathedral.
