The Duchy of Warsaw (; ; ), also known as the Grand Duchy of Warsaw and Napoleonic Poland, was a French client state established by Napoleon Bonaparte in 1807, during the Napoleonic Wars. It initially comprised the ethnically Polish lands ceded to France by Prussia under the terms of the Treaties of Tilsit, and was augmented in 1809 with territory ceded by Austria in the Treaty of Schönbrunn. 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 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.
History
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 officially 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 by Prussia during Partitions 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 June 28, 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 of June 28. Nevertheless, he proclaimed the attack on Russia as a second Polish war and allowed the Lithuanian Provisional Governing Commission to fall under Polish influence.
