In the early to mid 20th century, two seperate politic powers formed in China; the nationalists and communists. The Nationalists (also known as the Kuomintang) formed a political party under Sun-Yatsen in 1912, the first year of the People's Republic of China. The Communists were started by a group of young radicals from Beijing University in 1921. These two powers would fight for control over all of China. Each group had different things to bring to society's 'table' and helped to characterize this warring period. The fight for China was characterized by reform movements, special military tactics and operations, and changes in social classes in society.
