Vistula Land,[1][2] also known as Vistula Country (Russian: Привислинский край, romanized: Privislinskiy kray; Polish: Kraj Nadwiślański),[3] was the name applied to the lands of Congress Poland from 1867, following the defeats of the November Uprising (1830–1831) and January Uprising (1863–1864) as it was increasingly stripped of autonomy and incorporated into Imperial Russia.
In 1831, in the aftermath of the November Uprising, the Polish Army, the Constitution of the Kingdom of Poland, its parliament (Sejm) and local self-administration were disbanded.
The former Kingdom of Poland continued to use the Polish currency (złoty) and the Administrative Council retained some of its privileges (although it was directly controlled by the Russian governor Field Marshal Ivan Paskevich).
The 1867 reform, initiated after the failure of the January Uprising, was designed to tie the Kingdom of Poland more tightly to the administration structure of the Russian Empire.
[6] During the Imperial Russian Army's subsequent Great Retreat, it looted and abandoned the Kingdom of Poland, trying to emulate the scorched-earth policy adopted during the 1812 invasion.
In the March 1918 Treaty of Brest-Litovsk, Russia (by then embroiled in a civil war), effectively ceded all Polish territories it had formerly possessed to the German Empire and Austria-Hungary.
The sources are also unclear as to when the Kingdom of Poland (or Vistula land) officially ceased to exist; some argue it ended with the assumption of control by the German and Austro-Hungarian occupying authorities; others, that it ended with the proclamation of the Regency Kingdom of Poland in 1916; finally, some argue that it occurred only with the creation of the independent Second Polish Republic in 1918.
