nIn 1917, the tsar abdicated and a
provisional government, headed
by Alexander Kerensky, struggled
to maintain control of the
country.
nWhen reforms seemed slow in coming,
popular unrest ensued and by the
end of the year a second
revolution occurred, bringing
into power a radical new form of
government—Communism.
nUnder the Bolshevik banner, Vladimir
Lenin signed a treaty ending
hostilities with Germany and
ended any semblance of a multiparty
system.
nAn ensuing civil war killed millions,
but the Communist Red Army
prevailed, under the leadership
of Leon Trotsky.
