The Soviet Union was established by the Bolsheviks in 1922, in place of the Russian Empire. At the time of the 1917 Revolution, the Russian Orthodox Church was deeply integrated into the autocratic state, enjoying official status. This was a significant factor that contributed to the Bolshevik attitude to religion and the steps they took to control it. Thus the USSR became the first state to have, as an ideological objective, the elimination of religion and its replacement with universal atheism. The communist regime confiscated religious property, ridiculed religion, harassed believers, and propagated atheism in schools. The confiscation of religious assets was often based on accusations of illegal accumulation of wealth.
