How did the march revolution end the reign of czar nicholas ii?

In March 1917, the army barracks at Petrograd united striking workers in challenging socialist reforms, and Czar Nicholas II was enforced to step down from his leadership. Nicholas and his family were first detained at the Czarskoye Selo palace, then in the Yekaterinburg palace near Tobolsk. In July 1918, the improvement of anti-revolutionary forces caused the Yekaterinburg Soviet forces to fear that Nicholas might be set free.
