Boles?aw I of Masovia (Polish: Boles?aw I Mazowiecki; 1208 - ca. 25 February 1248), was Polish prince member of the Polish House of Piast, Duke of Sandomierz (only a part) during 1229-1232, Duke of Dobrzy? during 1233-1247 and Duke over whole Masovia during 1247-1248.

He was the second son of Konrad I of Masovia and Agafia of Rus. He was probably named after his great-grandfather, Boles?aw III Wrymouth. The death of his older brother Przemys? in 1228 left him as the eldest surviving child of his family.

Life

From a young age, Boles?aw I became part of the ambitious political projects of his father. In 1227, after the assassination of the High Duke of Poland Leszek I the White, he accompanied his father to Lesser Poland to participate in negotiations on the succession with his widow Grzymis?awa. In view of the failure of the talks, Boles?aw I received from his father the stronghold of Dobrzy? nad Wis until 1229, when Konrad I finally forced Grzymis?awa to surrender to Boles?aw I a part of the Duchy of Sandomierz, the district of Radom. Immediately, Boles?aw gave Dobrzy? nad Wis to his youngest brother, Siemowit I.

In 1231, Boles?aw I became involved with his father and brothers in the installation of the Teutonic Knights in the region of Che?mno Land. At the same time, he supported his father in the war to conquer Kraków, after the death of W?adys?aw III Spindleshanks in 1231. However, the quick intervention of Henry I the Bearded (High Duke of Poland from 1232 to 1238) and the invasion of Masovia by Prussians forced to Konrad I to abandon his plans; in addition, Henry I was able to take control of the entire Duchy of Sandomierz.

To compensate for the loss of the Duchy of Sandomierz, Konrad I offered his son parts of Masovia, with the district of Sieradz as the capital. Nevertheless, Konrad I retained control of foreign policy and of the army.

In 1234, Boleslaw received the north of Masovia of the Vistula and Bug Rivers in exchange for the region of Sieradz (who was strategically most closer to Lesser Poland and thus being more important for his father in his fights for the throne of Kraków), while his other brother Casimir I received Kujawy. This distribution of lands must be only temporary, because it was implicit that after the death of their father, the three surviving brothers (Boles?aw I, Casimir I and Siemowit I) had to make a new equitable re-distribution of the lands.

In subsequent years, Boles?aw I attacked his Prussian and Russian neighbors. He supported the Order of Dobrzy? and in 1238 he took part in the war against Daniel of Halych and Mindaugas of Lithuania.

In 1241, after the death of his father-in-law Henry II the Pious at the Battle of Legnica, Boles?aw I supported his father's military seizure of Kraków, who this time was able to conquer the Seniorate. His rule lasted only two years, until the Battle of Suchodo?y on 25 May 1243, when Konrad I was defeated and forced to retire to Sieradz.

With the death of Konrad I on 31 August 1247, new horizons opened for Boles?aw I. In his father's will, he received most of Masovia; shortly after, he had to face an attack of his brother Casimir I, because he was dissatisfied with his portion of their paternal inheritance. However, before the open war began, Boles?aw I died unexpectedly during the spring of 1248 (probably around 25 February).

By 1232 Boles?aw I married firstly with Gertrude (1218/20 - 23/30 April 1244/47), daughter of Henry II the Pious. They had no children.

Between 1245 and July 1247, Boles?aw I married secondly with his first cousin once removed[1] Anastasia, daughter of Alexander Vsevolodich, Prince of Bielsk (in turn a son of Vsevolod Mstislavich, Prince of Volhynia and Bielsk). They had no children. After her husband's death, she remarried with a Hungarian magnate called Demetri, probably member of the Aba family.

With no offspring from any of his marriages, in his will Boles?aw I bequeathed all his possessions to his younger brother Siemowit I. This however annoyed Casimir I, and soon the war continued between the surviving brothers.[2]
