Communism is a revolutionary socialist and leftist movement to create a classless and stateless social order, structured upon common ownership of the means of production, as well as a social, political and economic ideology that aims at the establishment of this social order. The ideology exists in many different forms.
Towards the end of the 19th century, the Russian revolutionary Vladimir Lenin developed his own form of Communism, known as Leninism, which eventually became the dominant ideology of the Soviet Union.
Communism became the favored form of government in Russia during the Russian Revolution of the early 20th century. The Bolsheviks, a division of the Russian Social Democratic Labour Party that split from the Menshevik faction at the Second Party Congress in 1903, rose up against the authoritarian Tsardom in 1917. The Russian Assassins supported the Bolsheviks and Lenin - whose brother, Aleksandr Ulyanov, was an Assassin - to replace the royal house with a populist government.
After many Russians migrated to the United States in fear of the Industrial Revolution, the fear of socialism and communism grew among the American populace. This became known as the Red Scare, which culminated in the Palmer Raids organized by Attorney General Alexander Mitchell Palmer. Numerous immigrants were arrested on suspicion of spreading radical leftist ideals, and deported back to Europe.
Lenin's successor, Joseph Stalin, was a puppet for the Templar Order, aiding in igniting the Second World War. While the Templar leadership of Abstergo Industries took up an anti-communist perspective towards their employees, they nonetheless used communism as a means to achieve their desired New World Order.
