French Emperor Napoléon Bonaparte's Grande Armée occupied Moscow from 14 September to 19 October 1812 during the Napoleonic Wars. It marked the summit of the French invasion of Russia. During the occupation, which lasted 36 days, the city was devastated by fire and Napoleon ordered a systematic looting of the churches to fill his war chest with silver.

The French invasion of Russia, also known as the Russian campaign and in Russia as the Patriotic War of 1812, was initiated by Napoleon with the aim of compelling the Russian Empire to comply with the continental blockade of the United Kingdom. Widely studied, Napoleon's incursion into Russia stands as a focal point in military history, recognized as among the most devastating military endeavors globally. In a span of fewer than six months, the campaign exacted a staggering toll, claiming the lives of nearly a million soldiers and civilians.
