Charles Gravier Vergennes
Charles Gravier, comte de Vergennes (December 20, 1717—February 13, 1787) was a French statesman and diplomat. His rivalry with the British, and his desire to avenge the disasters of the Seven Years' War, led to his support of the Thirteen Colonies in the American War of Independence, a step which would help bring about the French Revolution of 1789.
