The Duchy of Württemberg (German: Herzogtum Württemberg) was a duchy located in the south-western part of the Holy Roman Empire. It was a state of the Holy Roman Empire from 1495 to 1806. The dukedom's long survival for over three centuries was mainly due to its size, being larger than its immediate neighbors. During the Protestant Reformation, Württemberg faced great pressure from the Catholic emperors to remain loyal. Württemberg resisted repeated French invasions in the 17th and 18th centuries, the duchy being directly in the path of French and Austrian armies who were engaged in the long rivalry between the House of Bourbon and the House of Habsburg. In 1803, Napoleon raised the duchy to be the Electorate of Württemberg. On 1 January 1806, the last elector assumed the title of King of Württemberg. Later that year, on 6 August 1806, the last Emperor, Francis II, abolished (de facto) the Holy Roman Empire. Source: Wikipedia (en)
