Churches in Russia entered its final chapter by the year 1929. What started out as a decree by the Soviet government on the separation of Church and state ended with a violent attack on church property. The resistance to religion stemmed from a Marxist belief that “existence determines consciousness, and only knowledge derived from observed reality, without the intercession of any external force or mover is valid.” Thus, since religious belief has always been largely based on unwavering support of an idea without a known, proper source, the Bolsheviks saw this as a superstitious idea and as a source that could hamper the progress of a scientific state.
By 1923, the state had already increasingly placed restrictions on the church. The local police were recruited to close churches, using whatever methods necessary to do so. There were even mobs of citizens and anti-religious militants during the Russian civil war who vandalized churches and monasteries and went so far as to even kill bishops and priests.
Clearly, much of the damage of ridding the country of religious influence and propaganda had been successful. However, by the year 1929, the government placed even stricter restrictions on the church and imposed new and stiffer penalties. They also began using materials from churches for industry. For example, it was not uncommon to melt the metal from church bells for additional metal.
The Soviet Union certainly saw a significant amount of change in the year 1929 with the introduction of the first Five-Year Plan and the announcement to plan mass collectivization. However, it would seem that the anti-religious campaign had already been aggressively pursued and this important year for Russian history and the Soviet Union did not actually see much change on the religious front.
