The most widely documented significant outcome of the Russian Revolution of 1917 is the fall of the Russian Empire and the beginning of Marxian socialism under Vladimir Lenin and his Bolshevik revolutionaries. This marked the beginning of a new era in Russia, especially regarding its political and economic relations with other nation-states.
The Russian Revolution ended the rule of a dynasty that had lasted three hundred years. In the years preceding the 1917 revolution, Tsar Nicholas II had become increasingly unpopular with the working class majority, who suffered from poverty and famine. Though class struggle had long been marked by temporary but frequent conflicts between workers and police, it reached a head in 1917 when a spontaneous "bread riot" escalated into a large-scale revolutionary protest. As a result of this riot, the Tsar stepped down from power.
In the years following, Russia became symbolic of the spread of communism throughout the world.
