The Treaties of Tilsit were two agreements signed by Napoleon I of France in July 1807 in the town of Tilsit after his victory in Friedland. The first was signed on July 7 between Emperor Alexander I of Russia and Napoleon I of France, when they found themselves on a raft in the middle of the Neman River. The second was signed on 9 July with Prussia. The treaties came at the expense of the King of Prussia, who had already agreed to a ceasefire on 25 June, after the Grand Army conquered Berlin and pursued it to the easternmost frontier of his empire. At Tilsit, he ceded about half of his pre-war territories.

Canning, who had just been foreign minister, wanted to be there before. The Baltic powers were valuable allies and the Danish navy would be an important complement to the fleets already available to Napoleon. He therefore proposed a defence alliance for Denmark and promised its armed support and a large grant, provided that it had sent its fleet “as a sacred pawn” to a British port during the war. He hoped that the appearance of 80 ships and 15,000 soldiers before Copenhagen would immediately overburden the Danes and give them an apology for the submission, but he was disappointed. The Prince Regent of Denmark rejected the British proposals and gave in only after four days and four nights of bombing Copenhagen in September 1807. The 22 Danish Navy ships were then captured and transported to Portsmouth Harbour.
One wonders, however, whether Britain has really won something in the long run. Denmark remained hostile for the rest of the war; Sweden was defenceless and Napoleon had an excuse to describe the British as insidious and ruthless. Alexander instructed his envoy to tell Napoleon that an alliance between France and Russia “will guarantee the happiness and tranquillity of the world.” To find itself on neutral ground, the conference took place on a raft hastily built by the French in the middle of the river, with two large white tents on it. The main tent had a large green letter N on it overlooking the French side of the river and a large A on Russian. The Prussians discovered angrily that there was no initial for their king, and they must indeed receive the worst. For the first meeting, on June 25, the participants were transported by boat to the raft. Agreement between Russia and France, as well as Prussia and France. Napoleon I, after winning the Battle of Friedland, agreed to meet Alexander I on a raft on the Niemen River near the town of Tilsit, now in Russia, in East Prussia. Their negotiations, accompanied by Frederick William III of Prussia, resulted in both treaties. Prussia lost more than a third of its assets, had to pay heavy compensation to France and was forced to support a large French army on its soil.
The Polish lands annexed by Prussia under divisions were transformed into a French puppet state, the Grand Duchy of Warsaw. Russia recognized the Rhine Federation and was forced to join the continental system. Prussia abrogated its treaty in 1813, when it left the French after its invasion of Russia and joined the Russian emperor in a campaign against Napoleon in Germany.
