Besides the famous socialists we focused on, there were many other influential individuals that contributed a great part into socialism.
Plato (circa 428-c. 347 BC): Greek philosopher explained his ideal state of society in The Republic. The economic structure of the state is maintained by the merchant class. Security needs are met by the military class, and political leadership is provided by the philosopher-kings.
Sir Thomas More (1478-1535): English statesman and writer, who began the thought of socialism with his idea of Utopia, ideal and perfect communities that put society in the first place above the interest of individual.
Mao Tse-tong or Mao Zedong (1893-1976): Chinese Communist leader who was chairman of the Communist Party of China and the principal founder of the People's Republic of China. In Maoism, two types of "contradictions" must included in a communist (socialist) society, antagonistic contradictions and nonantagonistic contradictions. His socialist reforms such as The Great Leap Forward and the Great Proletarian Cultural Revolution moulded the modern Communist China.
Vladimir Ilich Lenin (1870-1924): Russian revolutionary and political theoretician, founder of the former USSR. His plans for revolution centred on a highly disciplined party of professional revolutionaries, who lead the working masses to an inevitable victory over Czarist absolutism. Lenin is considered one of the foremost revolutionary figures of 20th century Europe.
