The Duchy of Masovia (Polish: Ksi?stwo Mazowieckie) was a medieval duchy formed when the Polish Kingdom of the Piasts fragmented in 1138. It was located in the historic Masovian region of northeastern Kingdom of Poland. The duchy was re-incorporated into the Jagiellonian Kingdom of Poland by 1526.

Partitions of Masovia

The Duchy went through various border changes in the coming years, sometimes losing and sometimes gaining territory.

History

The lands of the Masovians east of the Vistula river had been conquered by the Piast duke Mieszko I of Poland (960–992) and formed a constituent part of his Civitas Schinesghe. The Masovian Diocese of P?ock was established in 1075.

Fragmentation of Poland in 1138:
  Duchy of Masovia of Boles?aw IV

Following the death of Duke Boles?aw III Wrymouth in 1138, as specified by his testament, the Masovian province was governed by his second son Boles?aw IV the Curly, who, after he had expelled his elder half-brother W?adys?aw II, in 1146 became Grand Prince (High Duke) of Poland. His Masovian realm also comprised the adjacent lands of Kujawy (Kuyavia) on the west bank of the Vistula.

Among the Piast Dukes of Masovia, Boles?aw's IV nephew Konrad I was Polish high duke from 1229 to 1232 and again from 1241 to 1243; he was the ruler who in 1226 called the Teutonic Order for help against the pagan Old Prussians threatening the northern borders of his territory. In turn he ceded the Prussian Che?mno Land (Kulmerland) to the knights in 1230; according to the Golden Bull of Rimini (dated 1226), issued by the Hohenstaufen emperor Frederick II, these lands became the nucleus of the Order State. In 1233 Konrad gave Kujawy to his second son Casimir I, while Masovia passed to the first-born Boles?aw I upon his death in 1247, succeeded by the youngest brother Siemowit I the next year.

While Siemowit's son Duke Konrad II (1264–1294) moved his residence to Czersk he and his brother Boles?aw II entered into a long-term conflict over the Polish seniorate with their Kujawy relatives and the Silesian Piasts, which estranged them from the Piast monarchy. When the kingdom was finally restored in 1295 by the coronation of Duke Przemys? II of Greater Poland, the Duchy of Masovia remained independent.

1313 partition:
  Duchy of P?ock under Wenceslaus
  Duchy of Rawa under Siemowit II
  Duchy of Czersk under Trojden I

Upon the death of Duke Boleslaus II in 1313, Masovia was divided among his sons:

As neither Siemowit II nor Boles?aw III of P?ock left any heirs, Trojden's son Duke Siemowit III (1341–1381) was able to re-unite most of the Masovian lands under his rule; in 1351 he and his brother Casimir became vassals of the Polish kings, while the Bishopric of P?ock had always been part of the Polish Archdiocese of Gniezno. Upon Siemowit's III death in 1381 however, Masovia was again partitioned between his sons:

Since the Polish-Lithuanian Union of 1385, Masovia was localized between the joined Jagiellonian states. The Dukes of Masovia also ruled the Duchy of Belz until 1462.

After the establishment of the Rawa and P?ock Voivodeships, in 1495 the last surviving son of Boleslaus IV, Duke Konrad III Rudy, once again united the remaining Masovian lands under his rule. However, the male line of the Masovian Piasts became extinct upon the death of his son Duke Janusz III in 1526, whereafter the duchy as a reverted fief became the Masovian Voivodeship of the Polish Crown.

Parts of the southern region of neighboring East Prussia received settlers and Protestant religious refugees who became known as the Mazurs. By the 18th century the portion of East Prussia in which they settled was sometimes referred to as Masuria (Masuren), and inhabited by a Protestant population of Germans and Poles.
