The Treaty of Campo Formio was signed on October 17, 1797, between the French Republic and the Austrian Empire. This agreement marked the end of the War of the First Coalition, which involved several European powers opposing France. The treaty resulted in significant territorial changes, with Austria ceding territories in northern Italy to France and recognizing French control over various regions. As part of the treaty, the French gained control of the regions of Lombardy and Venetia, while Austria retained Venice and its surrounding territories. The treaty also established a new political landscape in Europe, influencing future conflicts and alliances.
