The Three Principles of the People (Chinese: 三民主義; pinyin: Sānmín Zhǔyì; also translated as the Three People's Principles, San-min Doctrine, or Tridemism[1]) is a political philosophy developed by Sun Yat-sen as part of a philosophy to improve China made during the Republican Era. The three principles are often translated into and summarized as nationalism, democracy, and the livelihood of the people (or welfarism). This philosophy has been claimed as the cornerstone of the nation's policy as carried by the Kuomintang; the principles also appear in the first line of the national anthem of Taiwan.
