Treaty of Campo Formio is signed between France and Austria, ending the War of the First Coalition.

The Treaty of Campo Formio was signed on 17 October 1797 by Napoleon Bonaparte and Count Philipp von Cobenzl as representatives of the French Republic and the Austrian monarchy, respectively. The treaty followed the armistice of Leoben, which had been forced on the Habsburgs by Napoleon's victorious campaign in Italy. It ended the War of the First Coalition and left Great Britain fighting alone against revolutionary France.
