The Treaty of Tilsit, signed on July 7 and 9, 1807, was a series of agreements between Napoleon Bonaparte of France and Alexander I of Russia, along with Frederick William III of Prussia. These treaties were named after the town of Tilsit (now Sovetsk, Russia), where they were concluded.
Following the Battle of Friedland on June 14, 1807, where Napoleon's forces decisively defeated the Russians, Alexander I sought peace. This defeat, combined with the earlier losses at Austerlitz, left Russia in a vulnerable position, prompting the need for a peace settlement.
The Treaty of Tilsit marked a high point in Napoleon's domination of Europe, but it also sowed the seeds for future conflicts. The treaty's terms were seen as harsh by many European states, leading to a shift in European politics and the eventual downfall of the French Empire.
