However, the First World War and the Russian Revolution created turmoil in his native land. On 21 June 1917, the Diocesan Congress of clergy and laity elected Tikhon the ruling bishop of Moscow. On 14 August 1917 (OS), Tikhon was raised to the dignity of Metropolitan of Moscow. On the next day, the Local Council of the ROC, the first such convention since the late 17th century, opened in Moscow. The council's major decision that passed on 28 October 1917, days after the Bolsheviks seized power in Petrograd, was to restore the Patriarchy in the ROC. On 5 November 1917, after his election by vote as one of the three candidates for the reinstated Moscow Patriarchate, Metropolitan Vladimir of Kiev announced that Metropolitan Tikhon had been selected for the position after a drawing of lots as the new Patriarch of Moscow and All Russia.
