The Three Principles of the People (三民主義), or collectively known as the San-min Doctrine, is a political philosophy developed by Sun Yat-sen as part of a program to make China a free, prosperous, and powerful nation. Its legacy of implementation is most apparent in the governmental organization of the Republic of China, which administers Taiwan, Penghu, Quemoy, and Matsu Islands. The principles also appear in the first line of the National Anthem of the Republic of China.
