The Congress of Vienna was a conference of ambassadors of European states chaired by Austrian statesman Klemens Wenzel von Metternich, and held in Vienna from September 1814 to June 1815. The objective of the Congress was to provide a long-term peace plan for Europe by settling critical issues arising from the French Revolutionary Wars and the Napoleonic Wars. The goal was not simply to restore old boundaries, but to resize the main powers so they could balance each other off and remain at peace. The leaders were conservatives with little use for republicanism or revolution. France lost all its recent conquests, while Prussia, Austria and Russia made major territorial gains. Prussia added smaller German states in the west and 40% of the Kingdom of Saxony; Austria gained Venice and much of northern Italy. Russia gained parts of Poland.
