In two of history’s more renowned revolutions‚ the French and Russian‚ two great thinkers pushed the revolution onward‚ Robespierre and Lenin‚ respectively.

extent did Lenin establish Communism in Russia from 1920-1924? From an early age‚ Lenin opposed the Romanov autocratic regime‚ even more so following the execution of his brother for the assassination of Tsar Alexander III. Lenin was an avid follower of the writings of Karl Marx and believed communism was the way forward. He believed that everything should be owned by the government and then distributed evenly amongst the people. During the February 1917 revolution in Russia‚ Lenin was in exile

They were socially‚ economically and politically behind in many aspects; industrialising was a huge problem due to problems with serfdom as well as poor infrastructure and transport links which made industrialising uneven across the whole of Russia.

In this time period America faced a lot with the wars. Some of our states were being targeted by British Soldiers in the war. In 1780 the patriots from America tried to push the British soldiers out of our country. The American soldiers were to tired and hungry to fight anymore. Most of the soldiers tried to escape‚ but couldn’t. According to General Nathanael Greene‚ he had never witnessed such scenes before in his life. General Greene was very discouraged when he arrived to the scene. America finally

However‚ Lenin was not simply a catalyst in the many changes Russia faced; he was a most volatile reactant in the chemistry of Russian and world politics. Breaking the barrier between attaining both economic success and political achievement‚ Vladimir Lenin almost singlehandedly ended the Tsardom and brought the socialist “Bolshevik” party to power in Russia. Lenin’s unique

relationship to the war played a key role in setting the stage for revolution in Russia. Lenin‚ the leader of the radical Bolsheviks‚ was an outlaw and actually lived in Galicia and Switzerland at the beginning of World War I. He carried on a lively debate with the more moderate wing of the Russian Social Democrats called Mensheviks. The key issue was the relationship of revolution to war. Unlike the other socialist‚ Lenin actually was in favor of war at this time‚ because he thought it would weaken

Japan faced many political challenges during the allied occupation post World War 2‚ one of the primary challenges that were faced was the land reform that was introduced by the Japanese Government and furthermore implemented by the SCAP.
