The Congress of Vienna was one of the most important international conferences in European history after the downfall of the French Emperor Napoleon. It was a meeting of ambassadors of European states chaired by Austrian statesman Klemens von Metternich, and held in Vienna for seven months, from November 1814 to June 1815. The objective of the Congress was to settle critical issues arising from the French Revolutionary  and the Napoleonic Wars. The leaders were conservatives who did not want to upset the status quo in Europe.
