拉瓦省
The voivodeship had its capital in the town of Rawa Mazowiecka, and its origins date back to the second half of the 15th century. In 1462, after the deaths of local Piast dynasty dukes, Mazovian lands of Rawa and Gostynin were incorporated into the Crown of the Kingdom of Poland. In 1476, the Land of Sochaczew returned to Poland as well. Borders of Rawa Voivodeship remained unchanged for more than 300 years, until the second partition of Poland in 1793, when it was annexed by the Kingdom of Prussia.
