European Theater was a theater of operations during The Great War (1861 - 1867) set in Europe. The war in Europe was fought mostly between Russia and Prussia on one side and France and Austria on the other, with limited support from the British Empire. The goal of the Grand Triumverate in Europe was to knock France out the war and threaten Great Britain with a naval blockade by Prussian and Russian fleets. Also to encourage outright rebellion by the long-oppressed populace of Ireland, forcing the British to draw troops away from the North American Theater.
