The tsar lost control of his soldiers during the february revolution and could not enforce his rule, so he was forced to flee russia. step down. establish a new government. lead a militia to fight to regain power.

The tsar lost control of his soldiers during the February Revolution and could not enforce his rule, so he was forced to "step down from his throne" or the second option. forced to abdicate, renounce his throne, and then about a year later was executed with his family members.

Hope this helps!
