The Treaties of Tilsit were two agreements signed by Napoleon I of France in the town of Tilsit in July 1807 in the aftermath of his victory at Friedland. The first was signed on 7 July, between Emperor Alexander I of Russia and Napoleon I of France, when they met on a raft in the middle of the Neman River. The second was signed with Prussia on 9 July. The treaties were made at the expense of the Prussian king, who had already agreed to a truce on 25 June after the Grande Armée had captured Berlin and pursued him to the easternmost frontier of his realm. In Tilsit, he ceded about half of his pre-war territories.

Key Findings:

• Napoleon cemented his control of Central Europe
• Napoleon had created French sister republics, which were formalized and recognized at Tilsit: the Kingdom of Westphalia, the Duchy of Warsaw as a French satellite state and the Free City of Danzig
• Tilsit also freed French forces for the Peninsular War.
• Russia becomes an ally of France
• Prussia looses approximately 50% of her territory
• Napoleon is able to enforce the Continental System in Europe(with the exception of Portugal)
