The Constitution of the Kingdom of Poland (Polish: Konstytucja Królestwa Polskiego) was granted to the 'Congress' Kingdom of Poland by the King of Poland, Alexander I of Russia, who was obliged to issue a constitution to the newly recreated Polish state under his domain as specified by the Congress of Vienna. It was considered among the most liberal constitutions of its time; however, it was never fully respected by the government. It was modified during the November Uprising by the revolutionary government and discarded afterwards by the victorious Russian authorities.
The Congress of Vienna obliged Emperor Alexander I of Russia, in his role as King of Poland, to issue a constitution to the newly recreated Polish state under Russian domination. The new state would be one of the smallest Polish states ever, smaller than the preceding Duchy of Warsaw and much smaller than the Polish-Lithuanian Commonwealth. Because it was the Congress of Vienna which de facto created the Kingdom of Poland, it became unofficially known as the Congress Poland (Kongresówka).
A significant contributor to the constitution was Prince Adam Czartoryski, although the text was edited by the Emperor himself and his advisors. The constitution, promising freedom of speech and religious tolerance, among other freedoms, was considered to be among the most liberal in contemporary Europe, reflecting much of the thought of the Polish and Russian Enlightenments. Compared to the Constitution of the Duchy of Warsaw, the document which governed the lands that became part of the Kingdom of Poland during their time as the Duchy of Warsaw, it however prioritized the nobility (szlachta) and revoked some rights given to the Polish Jews and peasants. It was never fully respected by the Russian authorities, and increasingly its liberal but ambiguous provisions became manipulated, avoided and violated by the government. The parliament was supposed to have been called into session every two years, but after it became the scene of many clashes between liberal deputies and conservative government officials, it was in fact called only four times (1818, 1820, 1826, and 1830, with the last two sessions being secret). This disregard for the promised rights, among other factors, led to increasing discontent within Poland, eventually culminating in the failed November Uprising in 1830. The constitution was modified during the uprising, and in its aftermath, the constitution was superseded on 26 February 1832 by the much more conservative Organic Statute of the Kingdom of Poland granted by Tsar Nicholas I of Russia and never actually implemented.
The Constitution had 165 articles in seven titles.
The Kingdom of Poland was a constitutional monarchy in a personal union with the Russian Empire, with a common foreign policy. Each Emperor of Russia was also King of Poland. The parliament, military, administration and judiciary remained separate.
