The February Revolution (sometimes called the March Revolution,
due to discrepancies between the Russian and Western calendars)
was a large protest against Czar Nicholas II of Russia in March
1917. It forced the Czar to abdicate the throne and did not
allow his heir, Alexis, to inherit it. A provisional government
was established with Alexander Kerensky as the leader. The
ineffective new government was later overthrown in the October
Revolution, which installed the Bolshevik Party under V.I.
Lenin.
