After 1837 all voivodeships that constituted the Kingdom of Poland were turned into gubernias and became an integral part of Russia, ruled directly by the Russian tsars. In 1831 the Polish Army, constitution, Sejm and local self-administration were disbanded. Also all universities were closed, only to be reopened several years later as purely-Russian high schools.
Initially the territory maintained certain degree of autonomy than other gubernias. 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). However, by 1832 the currency and the customs border were abolished, as was the metric system and penal code. Also the Catholic Church was persecuted and most monasteries were closed and nationalised. In 1839 following the Synod of Polotsk the Greek-Catholic Church self-disbanded and united under the Russian Orthodox Church.
After the January Uprising in 1863, the coat of arms of the Congress Kingdom was abandoned, the Polish language was banned from office and education and the process of incorporation of the Polish gubernias and Russification of its administration was completed.
After the reform of 1867 (see Administrative division of Congress Poland) it consisted of 10 Governorates: Сувалкская (Suvalskaya), Ломжинская (Lomzhinskaya), Плоцкая (Plotskaya), Седлецкая (Sedletskaya) and Люблинская (Lublinskaya) by the right side of the Vistula River, and the remaining 5 by the left side: Калишская (Kalishskaya), Варшавская (Varshavskaya), Петроковская (Petrokovskaya), Радомская (Radomskaya) and Келецкая (Keletskaya).
The territory was a namestnichestvo until 1875 and later Governorate General - see Namestnik of the Kingdom of Poland.
During World War I, in 1915 the area was occupied by the Central Powers who proposed the Kingdom of Poland (1916–1918). In 1917 Russia ceded all Polish territories it had possessed to the German Empire and Austria-Hungary.
