In 1793 western Mazovia, and two years later the rest of the region were annexed by the Kingdom of Prussia in the Second and Third Partitions of Poland, while the south-eastern portion was annexed by Austria. In 1807 it became part of the Duchy of Warsaw. In 1815 the region was incorporated into the Congress Kingdom of Poland, which was dependent on Russia. In the 19th century Mazovia was the site of large Polish uprisings (November Uprising and January Uprising) against Russian rule. In that era pre-partition Mazovia was divided among Warsaw, Płock and Augustów (the last one replaced later by Łomża).
