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
Tsar 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 pursued him to the easternmost frontier of his realm. In Tilsit, he ceded about half of his pre-war territories.
