During the Second World War, Stalin reopened the churches. One reason could have been to motivate the majority of the population who had Christian beliefs. The reasoning behind this is that by changing the official policy of the party and the state towards religion, the Church and its clergymen could be to his disposal in mobilizing the war effort. On 4 September 1943, Stalin invited Metropolitan Sergius, Metropolitan Alexius and Metropolitan Nicholas to the Kremlin and proposed to reestablish the Moscow Patriarchate, which had been suspended since 1925, and elect the Patriarch. On 8 September 1943, Metropolitan Sergius was elected patriarch.
