The Tridemism, or Three Principles of the People, also known as the San-min Doctrine, is a Left-wing political philosophy made by Sun Yat-sen to make a free, strong and rich country.[1]
Sun Yat-sen's idea was that the people should start a nationalist revolution and replace a bad or weak government with a people's republic led by the people's party.
In this new government, capitalism would change into a mixed socialism. The goal was to make society and the economy more equal but without using violence to end class struggle, which is different from Marxism.[2]
