Stalin helped organise the July Days uprising, an armed display of strength by Bolshevik supporters. After the demonstration was suppressed, the Provisional Government initiated a crackdown on the Bolsheviks, raiding "Pravda". During this raid, Stalin smuggled Lenin out of the newspaper's office and took charge of the Bolshevik leader's safety, moving him between Petrograd safe houses before smuggling him to Razliv. In Lenin's absence, Stalin continued editing "Pravda" and served as acting leader of the Bolsheviks, overseeing the party's Sixth Congress, which was held covertly. Lenin began calling for the Bolsheviks to seize power by toppling the Provisional Government in a "coup d'état". Stalin and a fellow senior Bolshevik Leon Trotsky both endorsed Lenin's plan of action, but it was initially opposed by Kamenev and other party members. Lenin returned to Petrograd and secured a majority in favour of a "coup" at a meeting of the Central Committee on 10 October.
