Duchy of Warsaw
The Duchy of Warsaw was born from a treaty signed on a raft moored in the middle of the Niemen River. In 1807, Napoleon Bonaparte and Tsar Alexander I of Russia met at Tilsit and redrew the map of Europe. For the Polish people, who had watched their homeland carved up and erased from the map in three successive partitions during the late 18th century, what emerged from that meeting was something close to a miracle. A Polish state existed again. It was small. It was a client of France. Its ruler, Frederick Augustus I of Saxony, was a German king compelled by Napoleon to govern from afar. But it was there.
What follows is the story of that state: how it was built on French ambitions rather than Polish ones, how it raised an army of extraordinary size from a population of just over four million people, and how the dream it carried outlasted the man who created it.
Frederick Augustus I of Saxony did not choose to become Duke of Warsaw. Napoleon chose him. The King of Saxony was compelled to make his new realm a constitutional monarchy, complete with a parliament called the Sejm of the Duchy of Warsaw. On paper, this was a liberal arrangement. The constitution provided for a bicameral Sejm, divided into a Senate and a Chamber of Deputies, with a Council of Ministers serving as the executive body. Serfdom was partially abolished; serfs gained personal freedom, though not economic liberty. All classes were declared equal before the law, even as the nobility retained a privileged grip on Sejm membership. Roman Catholicism was the state religion, but the constitution also guaranteed religious tolerance.
The reality of governance, however, was something else entirely. Frederick Augustus's rule was subordinated at every turn to French strategic needs. The most powerful figure in the duchy was not the duke but the French ambassador, stationed in Warsaw. The duchy was denied its own diplomatic representation abroad. It was formally allied to France and described variously as a satellite state, a puppet state, and a client state. Napoleon's creation met with genuine enthusiasm from Polish republicans and from the large Polish diaspora in France, who had long seen Napoleon as the only figure capable of restoring Polish sovereignty. But the duchy they celebrated was never going to be allowed to grow into a truly independent nation. The French ambassador in Warsaw had more practical authority than the duke himself.
In 1809, a short war with Austria tested the young state. Polish and French forces won the Battle of Raszyn, but Austrian troops entered Warsaw anyway. The outcome tilted when Polish and French forces outflanked the Austrians and captured Kraków, Lwów, and areas that Austria had taken during the partitions. German colonists who had settled in Prussian-held lands during the partitions openly rose against the duchy during the conflict, revealing the ethnic fault lines that ran through the region.
When the Battle of Wagram ended the wider war, the Treaty of Schönbrunn handed the duchy a substantial territorial prize. West Galicia and the district of Zamość, which had been part of Austria's 1795 partition, were absorbed into the state. The duchy's initial area of around 104,000 square kilometres grew to roughly 155,000 square kilometres. The population climbed from approximately 2,600,000 to around 4,300,000. The six original departments, each named after its capital city, became ten. New departments centred on Kraków, Lublin, Radom, and Siedlce joined the original six that had governed the state since January 1807. The 1810 census put the population at 4,334,000, of whom 79 percent were ethnic Poles. Jews made up 7 percent of inhabitants, a figure the census likely underestimated. Germans accounted for 6 percent, and Lithuanians and Ruthenians each made up 4 percent.
Prince Józef Poniatowski commanded the duchy's armed forces as war minister, and he held the rank of Marshal of France. That dual role captured the duchy's fundamental tension: its military was formidable by any measure, yet it answered ultimately to Paris rather than Warsaw. At its founding, the army numbered 30,000 regular soldiers, drawn from both cavalry and infantry. By 1810, that figure had risen to over 60,000. By 1812, the year of Napoleon's invasion of Russia, the duchy had mobilized almost 120,000 troops from a population of just 4.3 million.
For scale, consider that Napoleon had a similar number of troops available at Austerlitz, drawn from a country of more than 25 million people. The duchy was giving France a proportionally extraordinary share of its young men. That sacrifice was grounded in hope. Poles expected that participation in the Russian campaign would earn their state an upgrade from duchy to kingdom. On the 28th of June, the Sejm formed the General Confederation of the Kingdom of Poland, establishing a government modeled on the old Polish-Lithuanian Commonwealth, with the aim of reclaiming the partitioned territories. Napoleon neither recognized the confederation nor committed to restoring Poland-Lithuania. He proclaimed the Russian campaign a second Polish war and allowed Polish influence over the Lithuanian Provisional Governing Commission, but he refused to make any permanent decision before a peace settlement with Russia.
Military recruitment was not the only drain on the duchy's people. In 1808, the French Empire imposed an agreement at Bayonne that forced the duchy to purchase from France the debts that Prussia owed to it. The debt totaled more than 43 million francs in gold. The duchy bought this obligation at a discounted rate of 21 million francs. Payments were made in installments over four years. Prussia, meanwhile, was unable to repay the duchy because it owed France a very large indemnity of its own. The Polish economy absorbed the loss.
That financial wound, combined with forced military recruitment and a drop in grain exports, pushed the duchy toward bankruptcy. The authorities responded with intensified agricultural development and modernization, and introduced protectionist policies to shield domestic industry. They succeeded in stabilizing the economy, but the damage was lasting enough that the phrase "sum of Bayonne" entered the Polish language as a synonym for a staggeringly large sum of money, a usage that persists to the present day. Inflation and over-taxation became defining features of life inside the duchy's borders.
Napoleon's Grande Armée marched into Russia in 1812 with a large Polish contingent among its ranks, driven by the hope of liberation. Russia refused to surrender after Moscow fell. The army's supply lines gave out. Few returned from the retreat. By January 1813, Russian forces had occupied most of the Duchy of Warsaw during their advance westward. The remainder of the duchy was handed back to Prussia. Some isolated fortresses held out for more than a year, but the duchy had ceased to function as a state in anything but name. Alexander I of Russia installed a Provisional Highest Council to govern the occupied territory through his generals.
At the Congress of Vienna in 1815, the major powers settled the duchy's fate. Russia sought all of the duchy's territory. Its demands were denied, but it retained its gains from the earlier partitions plus Białystok and the surrounding territory it had taken in 1807. The bulk of the former duchy, measuring some 128,000 square kilometres, became the Congress Kingdom of Poland, nominally in personal union with Russia, but de facto a puppet state. It retained separate status only until 1831, when Russia effectively annexed it. Its territories became the Vistula Land in 1867. Prussia regained a portion of what it had ceded in 1807: the Kulmerland and Gdańsk became part of the Province of West Prussia, while Greater Poland, covering approximately 29,000 square kilometres, was reconstituted as the Grand Duchy of Posen. That entity had nominal autonomy until the 1848 Greater Poland Uprising, after which it was fully absorbed into Prussia as the Province of Posen. Kraków, with a territory of some 1,164 square kilometres and a population of about 88,000, became the Free City of Cracow under the joint protection of its three powerful neighbors, a status it held until Austria annexed it in 1846 as the Grand Duchy of Kraków.
The Duchy of Warsaw lasted only eight years. At the 200th anniversary of its creation, commemorative events were held in Warsaw, and the Polish Ministry of Defense invited French and Polish soldiers to march together in a joint parade. President Nicolas Sarkozy agreed to the honor. That commemoration pointed to something the duchy's brief life had accomplished beyond its years: it demonstrated that Polish statehood was recoverable, even after catastrophe.
The duchy's creation came little more than a decade after the Second and Third Partitions had appeared to erase Poland from the map permanently. Even after Napoleon's defeat, a Polish state persisted in some form until the Russian Empire eliminated it as a separate entity. Counting the duchy and what followed, an identifiable Polish state remained in existence for at least a quarter of a century. The area that had already been liberated by a popular uprising against conscription rioting in 1806, even before Napoleon formalized the state, showed that the desire for Polish sovereignty predated and outlasted any single emperor's ambitions.
