Treaty of Moscow (A Greater War)

Causes
After the successful Napoleon's invasion of Russia that he called "Second Polish war" Alexander I, tsar of Russia, was captured in Moscow before he managed to escape and was forced to surrender and divide his land.

The Treaty
Negotiations began on the 13th of September 1812, Napoleon asked first for an independent satellite state in the Baltic and finally the Twin duchies of Curonie and Estonia were created, both governed by a transitional local government until a Duke was appointed. Frederick William III, king of Prussia, successfully asked for some lands in Lithuania so the province of Klaipeda was granted to him. Napoleon then claimed the lands of Grodno, Volkovysk and Brest-Litovsk for the Duchy of Warsaw.
