Sun Yat-sen 孫逸仙 (November 12, 1866–March 12, 1925) was a Chinese revolutionary and political leader who had a significant role in the overthrow of the Qing Dynasty. A founder of the Kuomintang, Sun was the first provisional president when the Republic of China was founded in 1912. He developed a political philosophy known as the Three Principles of the People which still heavily influences Chinese governments today.

Sun was a uniting figure in post-imperial China, and remains unique among 20th century Chinese politicians for being widely revered in both mainland China and Taiwan. In Taiwan, he is known by the posthumous name National Father, Mr. Sun Chungshan (國父　孫中山先生). On the mainland, Sun is also seen as a Chinese nationalist, and is highly regarded as the Forerunner of the Revolution (革命先行者). (source: Wikipedia)
