Congress Poland language used Polish
Congress Poland, Congress Kingdom of Poland, or Russian Poland, formally known as the Kingdom of Poland, was a polity created in 1815 by the Congress of Vienna as a semi-autonomous Polish state, a successor to Napoleon's Duchy of Warsaw. It was established when the French ceded a part of Polish territory to the Russian Empire following France's defeat in the Napoleonic Wars. In 1915, during World War I, it was replaced by the German-controlled nominal Regency Kingdom until Poland regained independence in 1918.
Following the partitions of Poland at the end of the 18th century, Poland ceased to exist as an independent nation for 123 years. The territory, with its native population, was split among the Habsburg monarchy, the Kingdom of Prussia, and the Russian Empire. After 1804, an equivalent to Congress Poland within the Austrian Empire was the Kingdom of Galicia and Lodomeria, also commonly referred to as "Austrian Poland". The area incorporated into Prussia initially also held autonomy as the Grand Duchy of Posen outside of German Confederation, but later was demoted to merely a Prussian province (the Province of Posen), and was subsequently annexed in 1866 into the North German Confederation, the predecessor of the German Empire.
The Congress Kingdom of Poland was theoretically granted considerable political autonomy by the liberal constitution. However, its rulers, the Russian emperors, generally disregarded any restrictions on their power. It was, therefore, little more than a puppet state in a personal union with the Russian Empire. The autonomy was severely curtailed following uprisings in 1830–31 and 1863, as the country became governed by viceroys, and later divided into governorates (provinces). Thus, from the start, Polish autonomy remained little more than fiction.The capital was located in Warsaw, which towards the beginning of the 20th century became the Russian Empire's third-largest city after St. Petersburg and Moscow. The moderately multicultural population of Congress Poland was estimated at 9,402,253 inhabitants in 1897. It was mostly composed of Poles, Polish Jews, ethnic Germans, Ukrainians, Lithuanians, and a small Russian minority. The predominant religion was Roman Catholicism and the official language used within the state was Polish until the failed January Uprising (1863) when Russian became co-official as a consequence. Yiddish and German were widely spoken by their native speakers.
The territory of Congress Poland roughly corresponds to modern-day Kalisz Region and the Lublin, Łódź, Masovian, Podlaskie and Holy Cross Voivodeships of Poland as well as southwestern Lithuania and a small part of the Grodno District of Belarus.
The Kingdom of Poland effectively came to an end with the Great Retreat of Russian forces in 1915 and was succeeded by the Government General of Warsaw, established by the Germans. In 1917, part of this was renamed as the short-lived Kingdom of Poland, a client state of the Central Powers, which had a Regency Council instead of a king.
