His most famous book, "The Communist Manifesto"4 was a great example of his economic thoughts. In terms of social matters, Marxism was suppose to create a sense of equality for all men and women in society and class structures were destroyed. Religion in society was considered as "a response to pain of being alive, the response to earthly suffering." In Towards a Critique of Hegel's Philosophy of Right (1844), Marx wrote, "Religion is the sigh of the oppressed creature, the feeling of a heartless world, and the soul of soulless circumstances."5 Marx acquired the need for religion, but regarded religion as a subtle part to his ideologies. He believes economic realities forestall the middle class to their happiness, and religion is provided as a solace to their distress. In terms of politics, Marxism has created socialism 6and evolved into communism7. Many countries up to present day has developed their government on the basis of Marxism and declared themselves as communists, socialists or social democrats. Marxism has influenced the politics of many countries up until today, such as Russia and China and many historic events of these nations. An example include China's Great Leap Forward (1958-1961), led by the Communist Party of China. Mao Zedong was the leader of this economic and social campaign to rapidly transform the country's agrarian economy into a communist society through immense industrialization8 agriculture and collectivization9. Private ownerships were abolished, and agricultural collectives were created. People gave up all sense of private ownership, referring to properties, tools, furnitures, jewelry and even their farm animals to the ownership of the commune. All public services were provided by the communes and all materials required for daily life is provided by the communes as well. However, as the Great Leap Forward carried on, at around 1959, people within the communes were faced with impossible tasks in labor ordered by the commune leaders.
