While Stalin was in exile, Russia entered the First World War, and in October 1916 Stalin and other exiled Bolsheviks were conscripted into the Russian Army, leaving for Monastyrskoe. They arrived in Krasnoyarsk in February 1917, where a medical examiner ruled Stalin unfit for military service because of his crippled arm. Stalin was required to serve four more months on his exile, and he successfully requested that he serve it in nearby Achinsk. Stalin was in the city when the February Revolution took place; uprisings broke out in Petrograd — as Saint Petersburg had been renamed — and Tsar Nicholas II abdicated to escape being violently overthrown. The Russian Empire became a "de facto" republic, headed by a Provisional Government dominated by liberals. In a celebratory mood, Stalin travelled by train to Petrograd in March. There, Stalin and a fellow Bolshevik Lev Kamenev assumed control of "Pravda", and Stalin was appointed the Bolshevik representative to the Executive Committee of the Petrograd Soviet, an influential council of the city's workers. In April, Stalin came third in the Bolshevik elections for the party's Central Committee; Lenin came first and Zinoviev came second. This reflected his senior standing in the party at the time.
