The Duchy of Warsaw (Polish: Księstwo Warszawskie, French: Duché de Varsovie, German: Herzogtum Warschau), also known as the Grand Duchy of Warsaw and Napoleonic Poland, was a Polish client state of the French Empire established by Napoleon Bonaparte in 1807, during the Napoleonic Wars. It comprised the ethnically Polish lands ceded to France by Prussia under the terms of the Treaties of Tilsit. It was the first attempt to re-establish Poland as a sovereign state after the 18th-century partitions and covered the central and southeastern parts of present-day Poland. The duchy was held in personal union by Napoleon's ally, Frederick Augustus I of Saxony, who became the Grand Duke of Warsaw and remained a legitimate candidate for the Polish throne. Following Napoleon's failed invasion of Russia, the duchy was occupied by Prussian and Russian troops until 1815, when it was formally divided between the two countries at the Congress of Vienna. The east-central territory of the duchy acquired by the Russian Empire was subsequently transformed into a polity called Congress Poland, and Prussia formed the Grand Duchy of Posen in the west. The city of Kraków, Poland's cultural centre, was granted "free city" status until its incorporation into Austria in 1846.

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 and successor to Napoleon's Duchy of Warsaw. It was established in the ethnically Polish lands ceded by the French to the Russian Empire following Napoleon's defeat. 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 state for 123 years. The territory, with its native population, was split between 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 and subsequently the German Empire had little autonomy and was merely a province – the Province of Posen. 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 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 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.

The Siege of Warsaw took place between April 24 and July 1, 1656. Swedish Empire forces had occupied the Polish capital without fighting in early September 1655 (see Deluge (history)). In late April 1656, Poles and Lithuanians began the siege, with the purpose of recapturing their capital. They were successful, but later lost the city for a second time after a battle held on July 28–30, 1656 (see Battle of Warsaw (1656)).

Masovian Voivodeship (Polish: Województwo Mazowieckie) was an administrative region of the Kingdom of Poland, and of the Polish–Lithuanian Commonwealth, from the 1526 to the partitions of the Polish–Lithuanian Commonwealth (1795). Together with Płock and Rawa Voivodeships, it formed the province of Masovia. Its area was 23,200 km2., divided into ten lands (see ziemia). The seat of the voivode was Warsaw, local sejmiks also convened in Warsaw, at St. Martin's church.

The Capital City of Warsaw, simply known as Warsaw, was an independent city of Warsaw, that functioned as the voivodeship of Poland, from 1919 to 1939. In 1931, it had a population of 1 171 898, and the area of 123 km². It was an enclave surrounded by the Warsaw Voivodeship.

Warsaw I is a Polish parliamentary constituency in the Masovian Voivodeship. It elects twenty members of the Sejm.The district has the number '19' for elections to the Sejm, and is named after the country's capital city, Warsaw. It covers the city county of Warsaw.

The Warsaw metropolitan area (known in Polish as: Aglomeracja Warszawska) is the metropolitan area of Warsaw, the capital of Poland. The metropolitan area covers ten counties in the Masovian Voivodeship, with an area of 6,100 km² and a population of around 3 million in 2019.The largest cities or towns within the metropolitan area are Warsaw, Pruszków, Legionowo, Otwock, Mińsk Mazowiecki, Piaseczno and Wołomin. Public transport in the metropolitan area is served by the Warsaw Transport Authority (Zarząd Transportu Miejskiego).

The Battle of Warsaw was fought in September 1831 between Imperial Russia and Poland. After a two-day assault on the city's western fortifications, the Polish defences collapsed and the city was evacuated. It was the largest battle and the final episode of the Polish–Russian War of 1830–31, a conflict that became better known as the November Uprising. After almost a year of heavy fighting, a large Russian force crossed the Vistula and besieged the capital of Poland on 20 August. Although the siege was partially lifted soon afterwards and a successful sortie allowed a communication route between the city and the rest of Poland, a large Russian force remained on the left bank of the Vistula and continued to threaten the city. Russian commander Ivan Paskevich counted on Polish surrender as his Polish counterpart, Jan Krukowiecki, was known to be a member of the moderate political forces, willing to negotiate with Russian tsar Nicholas I, who had been deposed from the Polish throne in January 1831 by the Sejm (Polish parliament). When a less conciliatory faction gained power in Warsaw and the Russian offer of surrender was refused, Paskevich ordered his forces to launch an assault against Warsaw's western defences. The assault started on 6 September 1831. Russian forces surprised the Poles by attacking the strongest Polish position in the suburb of Wola. Despite staunch defence of some of the ramparts, especially Fort 54 and Fort 56, after the first day the outer line of Polish defences had been breached by Russian infantry and artillery. The following day fights resumed, but this time Russian artillery was close enough to shell the western boroughs of the city itself. Although losses were similar on both sides, Polish authorities decided not to risk another Massacre of Praga and ordered the evacuation of the city. On 8 September 1831 Warsaw lay in Russian hands, and the remainder of the Polish Army retreated to Modlin. The November Uprising ended soon afterwards, with the remnants of the Polish Army crossing the borders of Prussia and Austria, to avoid being captured by the Russians. In the 19th century the fight for Warsaw became one of the icons of Polish culture, described by, among others, Polish romantic poets Adam Mickiewicz and Juliusz Słowacki. It was also the main inspiration behind Chopin's Revolutionary Étude, initially called the Étude on the Bombardment of Warsaw. The fall of Warsaw also garnered sympathy for the Poles and their quest for independence.
