Following the Congress, Russia gained a larger share of Poland (with Warsaw) and, after crushing an insurrection in 1831, the Congress Kingdom's autonomy was abolished. Poles faced confiscation of property, deportation, forced military service, and the closure of their own universities. The Congress was important enough in the creation of the state to cause the new country to be informally named for it. The Kingdom lost its status as a sovereign state in 1831 and the administrative divisions were reorganized. It was sufficiently distinct that its name remained in official Russian use, although in the later years of Russian rule it was replaced with the "Vistula Land" (Russian: Привислинский Край). Following the defeat of the November Uprising its separate institutions and administrative arrangements were abolished as part of increased Russification to be more closely integrated with the Russian Empire. However, even after this formalized annexation, the territory retained some degree of distinctiveness and continued to be referred to informally as Congress Poland until the Russian rule there ended as a result of the advance by the armies of the Central Powers in 1915 during World War I.
