The Duchy of Württemberg was a state in south-western Germany. It was a member of the Holy Roman Empire from 1495 to 1806. The dukedom's long survival for nearly four centuries was mainly due to its size, being larger than its immediate neighbors. During the Protestant Reformation, Württemberg faced great pressure from the Holy Roman Empire to remain a member. Württemberg resisted repeated French invasions in the 17th and 18th centuries. Württemberg was 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 of the Holy Roman Empire, and when he abolished the Empire in 1806, the Electorate was elevated as the Kingdom of Württemberg.
