In 1791, the Legislative Assembly replaced the National Assembly. France was now a constitutional monarchy. The king remained head of state. Apart from a suspensive veto, however, he had little influence on politics. The parliament consisted of new deputies, most of whom were politically inexperienced. The most consequential decision of the Legislature was the declaration of war on Austria in April 1792. The war went badly and deepened the internal crisis. Radical forces took the initiative. On August 10, 1792, the people of Paris stormed the Tuileries Palace. The monarchy was thus effectively ended. New elections were called for a National Convention.
