Sun Yat-sen’s Four-Point Plan was based on the Three Principles of the People, a political theory developed by Sun Yat-sen, the founding father of the Republic of China.
The Three Principles of the People are: nationalism, democracy, and people’s livelihood. Nationalism advocates for the overthrow of the Qing dynasty and the establishment of a republic. Democracy advocates for the establishment of a constitutional government based on the principles of popular sovereignty and the rule of law. People’s livelihood advocates for the improvement of the living standards of the Chinese people.
