The Kingdom of Württemberg was a German state that existed from 1805 to 1918, located within the area that is now Baden-Württemberg. The kingdom was a continuation of the Duchy of Württemberg, which existed from 1495 to 1805. Prior to 1495, Württemberg was a county in the former Duchy of Swabia, which had dissolved after the death of Duke Conradin in 1268.

The Treaty of Schönbrunn, sometimes known as the Peace of Schönbrunn or the Treaty of Vienna, was signed between France and Austria at Schönbrunn Palace near Vienna on 14 October 1809. The treaty ended the Fifth Coalition during the Napoleonic Wars, after Austria had been defeated at the decisive Battle of Wagram on 5–6 July.
