Duchy of Warsaw in the context of "Congress Poland"

Warsaw, officially the Capital City of Warsaw, is the capital and largest city of Poland. The metropolis stands on the River Vistula in east-central Poland. Its population is officially estimated at 1.86 million residents within a greater metropolitan area of 3.27 million residents, which makes Warsaw the 6th most-populous city in the European Union. The city area measures 517 km (200 sq mi) and comprises 18 districts, while the metropolitan area covers 6,100 km (2,355 sq mi). Warsaw is classified as an alpha global city, a major political, economic and cultural hub, and the country's seat of government. It is also the capital of the Masovian Voivodeship.

Warsaw traces its origins to a small fishing town in Masovia. The city rose to prominence in the late 16th century, when Sigismund III decided to move the Polish capital and his royal court from Kraków. Warsaw surpassed Gdańsk as Poland's most populous city by the 18th century. It served as the capital of the Polish–Lithuanian Commonwealth until 1795, and subsequently as the seat of Napoleon's Duchy of Warsaw. The 19th century and its Industrial Revolution brought a demographic boom, which made it one of the largest and most densely populated cities in Europe. Known then for its elegant architecture and boulevards, Warsaw was bombed and besieged at the start of World War II in 1939. Much of the historic city was destroyed and its diverse population decimated by the Ghetto Uprising in 1943, the general Warsaw Uprising in 1944, and systematic razing.

The War of the Fifth Coalition was a European conflict in 1809 that was part of the Napoleonic Wars and the Coalition Wars. The main conflict took place in Central Europe between the Austrian Empire of Francis I and Napoleon's French Empire. The French were supported by their client states—the Kingdom of Italy, the Confederation of the Rhine and the Duchy of Warsaw. Austria was supported by the Fifth Coalition which included the United Kingdom, Portugal, Spain, and the Kingdoms of Sardinia and Sicily, although the latter two took no part in the fighting. By the start of 1809 much of the French army was committed to the Peninsular War against Britain, Spain and Portugal. After France withdrew 108,000 soldiers from Germany, Austria attacked France to seek the recovery of territories lost in the 1803–1806 War of the Third Coalition. The Austrians hoped Prussia would support them, having recently been defeated by France, but Prussia chose to remain neutral.

On 10 April 1809, Austrian forces under Archduke Charles crossed the border of Bavaria, a French client state. The French response, under Louis-Alexandre Berthier, was disorganised but order was imposed with the arrival of Napoleon on 17 April. Napoleon led an advance to Landshut, hoping to cut off the Austrian line of retreat and sweep into their rear. Charles crossed the Danube at Regensburg, which allowed him to retreat eastwards, although he failed to reach the Austrian capital, Vienna, before the French. A French assault across the Danube was repulsed on 21–22 May at the Battle of Aspern-Essling but a repeat attack was successful in July. Napoleon won a major victory at the 5–6 July Battle of Wagram, which forced the Austrians to sign the Armistice of Znaim on 12 July. Austrian invasions of the Duchy of Warsaw and Saxony (where they fought alongside the Black Brunswickers) were repulsed and they were driven out of their territories in Italy. British forces landed in Walcheren, in the French client state of Holland, but were unable to seize their objective of capturing Antwerp and later withdrew.

The French invasion of Russia, also known as the Russian campaign, the Second Polish War, and in Russia as the Patriotic War of 1812, was initiated by Napoleon with the aim of compelling the Russian Empire to comply with the continental blockade of the United Kingdom. Widely studied, Napoleon's incursion into Russia remains a focal point in military history, recognized as among the most devastating military endeavors to ever unfold. In a span of fewer than six months, the campaign exacted a staggering toll, claiming the lives of nearly a million soldiers and civilians.

Beginning on 24 June 1812, the initial wave of the multinational Grande Armée crossed the Neman River, marking the entry from the Duchy of Warsaw into Russia. Employing extensive forced marches, Napoleon rapidly advanced his army of nearly half a million individuals through Western Russia, encompassing present-day Belarus, in a bid to dismantle the disparate Russian forces led by Barclay de Tolly and Pyotr Bagration totaling approximately 180,000–220,000 soldiers at that juncture. Despite losing half of his men within six weeks due to extreme weather conditions, diseases and scarcity of provisions, Napoleon emerged victorious in the Battle of Smolensk. However, the Russian Army, now commanded by Mikhail Kutuzov, opted for a strategic retreat, employing attrition warfare against Napoleon compelling the invaders to rely on an inadequate supply system, incapable of sustaining their vast army in the field.

The Treaties of Tilsit (French: Traités de Tilsit), also collectively known as the Peace of Tilsit (German: Friede von Tilsit; Russian: Тильзитский мир, romanized: Tilzitski mir), were two peace treaties signed by French Emperor Napoleon in the town of Tilsit in July 1807 in the aftermath of his victory at Friedland, at the end of the War of the Fourth Coalition. The first was signed on 7 July, between Napoleon and Russian Emperor Alexander I, when they met on a raft in the middle of the Neman river. The second was signed with Prussia on 9 July. The treaties were made at the expense of King Frederick William III of Prussia, who had already agreed to a truce on 25 June after the Grande Armée had captured Berlin and pursued him to the easternmost frontier of his realm.

In Tilsit, Prussia ceded about half of its pre-war territories. From these territories, Napoleon had created French client states, which were formalized and recognized at Tilsit: the Kingdom of Westphalia, the Duchy of Warsaw and the Free City of Danzig; the other ceded territories were awarded to existing French client states and to Russia.

Łódź is a city in central Poland and a former industrial centre. It is the capital of Łódź Voivodeship, and is located 120 km (75 mi) south-west of Warsaw. As of 2024, Łódź has a population of 645,693, making it the country's fourth largest city.

Łódź first appears in records in the 14th century. It was granted town rights in 1423 by the Polish King Władysław II Jagiełło and it remained a private town of the Kuyavian bishops and clergy until the late 18th century. In the Second Partition of Poland in 1793, Łódź was annexed to Prussia before becoming part of the Napoleonic Duchy of Warsaw; the city joined Congress Poland, a Russian client state, at the 1815 Congress of Vienna. The Second Industrial Revolution (from 1850) brought rapid growth in textile manufacturing and in population owing to the inflow of migrants, a sizable part of which were Jews and Germans. Ever since the industrialization of the area, the city had been multinational and struggled with social inequalities, as documented in the novel The Promised Land by Nobel Prize–winning author Władysław Reymont. The contrasts greatly reflected on the architecture of the city, where luxurious mansions coexisted with red-brick factories and dilapidated tenement houses.

The first Battle of Raszyn was fought on 19 April 1809 between armies of the Austrian Empire under Archduke Ferdinand Karl Joseph of Austria-Este and the Duchy of Warsaw under Józef Antoni Poniatowski, as part of the War of the Fifth Coalition in the Napoleonic Wars. The battle was not decisive, but it did result in the Austrians obtaining their goal by capturing the Polish capital Warsaw.

Uhlan (/ˈuːlɑːn, ˈjuːlən/; French: uhlan; German: Ulan; Lithuanian: ulonas; Polish: ułan) is a type of light cavalry, primarily armed with a lance. The uhlans started as Lithuanian irregular cavalry, that were later also adopted by other countries during the 18th century, including Poland, France, Russia, Prussia, Saxony, and Austria. The term "lancer" was often used interchangeably with "uhlan"; the lancer regiments later formed for the British Army were directly inspired by the uhlans of other armies (even though they were never known by that name).

Uhlans traditionally wore a double-breasted short-tailed jacket with a coloured plastron panel at the front, a coloured sash, and a square-topped Polish lancer cap (rogatywka, also called czapka). This cap or cavalry helmet was derived from a traditional Polish cap design, formalised and stylised for military use. Their lances were traditionally topped with a small, swallow-tailed flag (pennon) just below the spearhead.

The Battle of Leipzig, also known as the Battle of the Nations, was fought from 16 to 19 October 1813 at Leipzig, Saxony. The Coalition armies of Austria, Prussia, Sweden, and Russia, led by Tsar Alexander I, Karl von Schwarzenberg, and Gebhard von Blücher, decisively defeated the Grande Armée of French Emperor Napoleon Bonaparte. Napoleon's army also contained Polish and Italian troops, as well as Germans from the Confederation of the Rhine (mainly Saxony and Württemberg). The battle was the culmination of the German campaign of 1813 and involved about 560,000 soldiers, 2,200 artillery pieces, the expenditure of 400,000 rounds of artillery ammunition, and 133,000 casualties, making it the largest battle of the Napoleonic Wars, and the largest battle in Europe prior to World War I.

Decisively defeated, Napoleon was compelled to return to France while the Sixth Coalition kept up its momentum, dissolving the Confederation of the Rhine and invading France early the next year. Napoleon was forced to abdicate and was exiled to Elba in May 1814.
