The Coalition was one of the two major alliance of the Great War, and where the victors in the war. The initial founders were the Ottoman Empire, French Empire, and the United States. The Persian Empire later joined following the sinking of Persian merchant ship by an British warship, causing anti-British sentiment in the nation.


The Coalition was founded after France, the United States, and Ottoman Empire signed separate alliances to protect themselves from the "imperialist" British and Russians, as well as the Prussians and Austrians. The Coalition was originally comprised of the United States, France and Ottoman Empire, and then smaller French-dependent countries joined the Coalition. The exact formation date is unclear, but is determined to be between November and December of 1805.
