The Grand Triumverate was an alliance formed in 1863 between the United States of America, Prussia (later the German Empire), and the Russian Empire. The alliance was formed at the height of the Great War and its purpose was to make sure neither country left the war and abandoned its allies once each country achieved its own goals. While these three weren't the only ones on this side they were the only three to remain allied after the war's end. After the war the alliance's purpose was to help preserve and protect each nation's interests. For much of the later half of the 19th century the alliance was the dominant political force on the international stage. The alliance would serve as the basis for its rival The League of Great Powers.
