During the revolution, discontent grew; factory workers had gone on strike due to pay disparities, therefore causing grief amongst the country. By 25 February, Petrograd was shut down, causing further chaos. The Tsar had by then ordered soldiers to shoot demonstrators. During this time, the government had collapsed. As a result, the State Duma called for Nicholas to abdicate -- on 2 March, Nicholas abdicated, and the Tsar would be replaced by the Provisional Government.
