, the commander-in-chief of the Duchy of Warsaw's army The area of the duchy had already been liberated by
a popular uprising that had escalated from anti-conscription rioting in 1806. One of the first tasks for the new government included providing food to the French army fighting the Russians in
East Prussia. The Duchy of Warsaw was created by French Emperor
Napoleon I, as part of the
Treaty of Tilsit with
Prussia. Its creation met the support of both local republicans in partitioned Poland and the large Polish diaspora in France, who openly supported Napoleon as the only man capable of restoring Polish sovereignty after the
Partitions of Poland of the late 18th century. However, it was created as a
satellite state (and was only a
duchy, rather than a kingdom). The Duchy has also been described as a
puppet state or a
client state of Napoleon's France. The newly recreated state was formally an independent duchy, allied to
France, and in a
personal union with the
Kingdom of Saxony. King
Frederick Augustus I of Saxony was compelled by Napoleon to make his new realm a
constitutional monarchy, with a parliament (the
Sejm of the Duchy of Warsaw). The Varsovian duchy was never allowed to develop as a truly independent state; Frederick Augustus' rule was subordinated to the requirements of the French ''
raison d'état'', who largely treated the state as a source of resources. The most important person in the duchy was, in fact, the French ambassador, based in the duchy's capital, Warsaw. Significantly, the duchy lacked its own diplomatic representation abroad. In 1809, a short war with
Austria started. Although the Duchy of Warsaw won the
Battle of Raszyn, Austrian troops entered Warsaw, but Varsovian and French forces then outflanked their enemy and captured
Kraków,
Lwów and some of the areas annexed by Austria in the
Partitions of Poland. During the war, the German colonists settled in Prussia during the Partitions, and openly rose up against the Varsovian government. After the
Battle of Wagram, the ensuing
Treaty of Schönbrunn allowed for a significant expansion of the duchy's territory southwards with the regaining of once-Polish and Lithuanian lands.
Peninsular War Napoleon's campaign against Russia As a result of Napoleon's campaign in 1812 against Russia, the Poles expected that the duchy would be upgraded to the status of a kingdom and that during Napoleon's invasion of Russia, they would be joined by the liberated territories of the
Grand Duchy of Lithuania, Poland's historic partner in the
Polish–Lithuanian Commonwealth. On 28 June, the Sejm formed the
General Confederation of the Kingdom of Poland, establishing a system of government similar to the former commonwealth with the hope of reclaiming the partitioned territories. However, Napoleon did not want to make a permanent decision that would tie his hands before his anticipated peace settlement with Russia, and did not recognize the
confederation. Nevertheless, he proclaimed the attack on Russia as a
second Polish war and allowed the
Lithuanian Provisional Governing Commission to fall under Polish influence. Any peace settlement or restoration of Poland-Lithuania was not to be, however. Napoleon's
Grande Armée, including a substantial contingent of Polish troops, set out with the purpose of bringing the Russian Empire to its knees, but his military ambitions were frustrated by his failure to supply the army in Russia and Russia's refusal to surrender after the capture of Moscow; few returned from the march back. The failed campaign against Russia proved to be a major turning point in Napoleon's fortunes. After Napoleon's defeat in the east, most of the territory of the Duchy of Warsaw was occupied by Russia in January 1813 during their advance on France and its allies. The rest of the duchy was restored to Prussia. Although several isolated fortresses held out for more than a year, the existence of the Varsovian state in anything but name came to an end.
Alexander I of Russia created a Provisional Highest Council of the Duchy of Warsaw to govern the area through his generals.
The Congress of Vienna and the Fourth Partition Although many European states and ex-rulers were represented at the
Congress of Vienna in 1815, the decision-making was largely in the hands of the major powers. It was perhaps inevitable, therefore, that both Prussia and Russia would effectively partition Poland between them; Austria was to more or less retain its gains of the First Partition of 1772. Russia sought all territories of the Duchy of Warsaw. It kept all its gains from the three previous partitions, together with Białystok and the surrounding territory that it had obtained in 1807. Its demands for the whole Duchy of Warsaw were denied by other European powers. Prussia regained some of the territory it had lost to the Duchy of Warsaw in 1807: a portion of what it had conquered in the Second Partition. The
Kulmerland and
Gdańsk (Danzig) became part of the
Province of West Prussia; the remaining territories (i.e.,
Greater Poland/Poznań), which covered an area of approximately , were reconstituted into the
Grand Duchy of Posen. The Grand Duchy and its populace had some nominal autonomy (although it was
de facto subordinate to Prussia) but following the
1848 Greater Poland Uprising was fully integrated into Prussia as the
Province of Posen. The city of Kraków and some surrounding territory, previously part of the Duchy of Warsaw, were established as the semi-independent
Free City of Cracow, under the "protection" of its three powerful neighbors. The city's territory measured some , and had a population of about 88,000 people. The city was eventually annexed by Austria in 1846, becoming the
Grand Duchy of Kraków. Finally, the bulk of the former Duchy of Warsaw, measuring some , was re-established as what is commonly referred to as the "
Congress Kingdom" of Poland, in a
personal union with the
Russian Empire. This broadly corresponded to the Prussian and Austrian portions of the Third Partition (apart from the area around Białystok), plus around half of Prussia's Second Partition conquests and a small part of Austria's First Partition gains.
De facto a Russian
puppet state, it maintained its separate status only until 1831 when it was effectively annexed to the Russian Empire. Its constituent territories became the
Vistula Land in 1867. == Government and politics ==
