The Second Coalition War (1798-1802) was a conflict involving a coalition of European powers against the French Republic. The main participants included Austria, Russia, Britain, and Naples, who aimed to curb the expansion of French influence following the French Revolution. The war saw several significant battles, including the Battle of Marengo, where the French, led by Napoleon Bonaparte, achieved a decisive victory. The war ended with the signing of the Treaty of Amiens in 1802, which temporarily established peace between France and Britain. However, the underlying tensions remained unresolved, setting the stage for future conflicts in Europe.
