Sun Yat-sen (12 November 1866 12 March 1925) was a Chinese revolutionary and political leader. As the foremost pioneer of Nationalist China, Sun is frequently referred to as the Founding Father of Republican China. Sun played an instrumental role in inspiring the overthrow of the Qing Dynasty, the last imperial dynasty of China. He was the first provisional president when the Republic of China (ROC) was founded in 1912 and later co-founded the Chinese National People's Party or Kuomintang (KMT) where he served as its first leader. Sun was a uniting figure in post-Imperial China, and remains unique among 20th-century Chinese politicians for being widely revered amongst the people from both sides of the Taiwan Strait.
