Frederick Augustus was proclaimed King of Saxony on 20 December 1806. After the [[Treaties of Tilsit|Treaty of Tilsit]], which [[Frederick William III of Prussia]] and Tsar [[Alexander I of Russia]] concluded with Napoleon in July 1807, Frederick Augustus was also named Grand Duke of Warsaw. Although he had rejected the offer of the throne of Poland in 1795 by the Sejm, he could not refuse a Polish title a second time.<ref name="Flathe" /><ref name="Schaefer" />

Article V of the [[Constitution of the Duchy of Warsaw]], which Napoleon dictated to Saxony, was linked to the Polish Constitution of 1791 and joined the Duchy of Warsaw hereditarily to the [[House of Wettin|Royal House of Saxony]]. Geopolitically the Duchy of Warsaw comprised the areas of the 2nd and 3rd [[Partitions of Poland|Prussian partitions]] (1795), with the exception of [[Gdańsk|Danzig]], which was made into the [[Free City of Danzig (Napoleonic)|Free City of Danzig]] under joint French and Saxon "protection", and the district around [[Białystok]], which was given to Russia. The area under Prussian control was made up of territory from the former Prussian provinces of [[New East Prussia]], [[Southern Prussia]], [[New Silesia]], and [[West Prussia]]. In addition, the new state was given the area along the [[Noteć]] river and the "[[Chełmno Land|Land of Chełmno]]".

Altogether, the Duchy had an initial area of around 104,000&nbsp;km<sup>2</sup>, with a population of approximately 2,600,000. The bulk of its inhabitants were Poles.

In 1809, [[Austrian Empire|Austria]] was successfully [[War of the Fifth Coalition|defeated]] by Polish–Saxon troops when it attempted to take possession of the Duchy and for its part had to cede to the Duchy of Warsaw Polish regions absorbed up to 1795, among them the old Polish royal city of [[Kraków]]. In July 1812 Frederick Augustus ratified a proclamation of the [[Sejm of the Duchy of Warsaw]] that restored the Kingdom of Poland. Napoleon lodged a protest against this action.
