Hundred Days' Reform
This movement, generously supported by overseas Chinese funds, also gained political support with regional military officers and some of the reformers who had fled China after the Hundred Days' Reform. Sun's political philosophy was conceptualized in 1897, first enunciated in Tokyo in 1905 and modified through the early 1920s. It centered on the Three Principles of the People: "nationalism, democracy, and people's livelihood".
