Fought over the course of 12 long years, the Napoleonic Wars marked a period of relentless conflict between Napoleon’s France and a variety of coalitions that involved more or less every country in Europe at some stage.

Coming after from the War of the First Coalition (1793-97), and the start of the War of the Second Coalition in 1798, the Battle of Marengo was both a vital victory for France and a transformative moment in Napoleon’s military career. It makes for a fitting place to begin our timeline of the Napoleonic Wars.
