The Brześć Kujawski Voivodeship (, ) was a unit of administrative division and local government in the Kingdom of Poland (later Polish–Lithuanian Commonwealth), from the 14th century to the Second Partition of Poland in 1793. It was part of the historic Kujawy region and the Greater Polish prowincja. Originally, its name was Brzesc Voivodeship (Wojewodztwo brzeskie), but after the 1569 Union of Lublin, it was renamed into Brzesc Kujawski Voivodeship, to distinguish it from Lithuanian Brest Litovsk Voivodeship (Polish: Wojewodztwo brzesko-litewskie). Geography Its area was 3,276 sq. kilometers, divided into five counties. The seat of the voivode was at Brześć Kujawski, while local sejmiks for both Brześć Kujawski and Inowrocław Voivodeships took place at Radziejow. It was one of the smallest and most densely populated voivodeships of the Commonwealth. Zygmunt Gloger in his monumental book Historical Geography of the Lands of Old Poland provides this description of Brześć Kujawski Voivodeship: “East of the land of the Polans lies the region of Kujawy, most of which stretches along left bank of the Vistula. The region was divided into two voivodeships: those of Brześć Kujawski, and Inowrocław. Third part of historic Kujawy, the Dobrzyn Land, lies on the right bank of the Vistula. Duke Boleslaw Krzywousty, while writing his testament in 1138, united Kujawy and Mazovia, giving it to his son Boleslaw IV the Curly (...) The dynasty of Mazovian Piasts lasted until the 16th century, while the Kujawian Piasts died out in the 14th century. As a result, Kujawy returned to the Crown of the Kingdom of Poland in 1434, two hundred years before Mazovia. It is not known when the province was divided into two voivodeships, but in Horodlo in 1413 (see Union of Horodlo), two Kujawian voivodes were already present: Maciej of Labiszyn was the voivode of Brześć, and Janusz of Koscieliska was the voivode of Gniewkowo, later Inowrocław (...) The area of Brześć Kujawski Voivodeship was almost 60 sq. miles, with 67 Roman-Catholic parishes, 13 towns and 567 villages. It was divided into five counties: Brześć Kujawski, Radziejow, Przedecz, Kowal and Kruszwica. All counties were among the smallest in the Province of Greater Poland, as Przedecz County had the area of 9 sq. miles, while Kruszwica County was even smaller, with 6 sq. miles. At the same time, however, Brześć Kujawski Voivodeship (together with Łęczyca Voivodeship) was most densely populated of all voivodeships of the Polish–Lithuanian Commonwealth. Its
