The Russian Empire (also known as Russia) was a state that existed from 1721 until it was overthrown by the short-lived February Revolution in 1917. One of the largest empires in world history, stretching over three continents, the Russian Empire was surpassed in landmass only by the British and Mongol empires. The rise of the Russian Empire happened in association with the decline of neighboring rival powers: the Swedish Empire, the Polish–Lithuanian Commonwealth, Persia and the Ottoman Empire. It played a major role in 1812–14 in defeating Napoleon's ambitions to control Europe, and expanded to the west and south.
Russia does not play a major role in the series. The only role it plays is that they are (propably) allied against Germany.
