Since 1815, following Napoleon's defeat, Rawa became part of the Russian-controlled Congress Poland. In 1822, a town hall was built together with tenement houses in the main town square, and in 1829-1830 a hospital was completed. Rawa quickly modernized, but this process was halted by the Tsarist repression after the failed November Uprising of 1830. On February 4, 1863, Rawa was captured by the rebels of the January Uprising. The town was almost completely destroyed in 1915 during World War I. After the war, in 1918, it was reintegrated with Poland, as the country regained independence.
