Sun Yat-sen (born Sun Deming; 12 November 1866 – 12 March 1925) was a Chinese statesman, physician, and political philosopher, who served as the provisional first president of the Republic of China and the first leader of the Kuomintang (Nationalist Party of China). He is called the "Father of the Nation" in the Republic of China, and the "Forerunner of the Revolution" in the People's Republic of China.

The Double Ten Revolution was launched by the Chinese under the leadership of Dr. Sun Yat-Sen known as the "Father of China's Independence". He wanted the Chinese to be able to establish a republican government and abolish that monarchy that believed that Emperors were appointed by God in accordance with the Mandate of Heaven.

On October 10, 1911 he launched the Double Ten Revolution against the Manchu government in collaboration with Tomenghui groups and forced Henry Pu Yi to leave the rule as emperor and live as a common citizen. Despite the victory of the revolution of Sun Yat-Sen found it difficult to establish an centralized government because he could not get the support of the people from different provinces of China.

Sun is considered to be one of the greatest leaders of modern China, but his political life was one of constant struggle and frequent exile. After the success of the revolution in 1911, he quickly resigned as President of the newly founded Republic of China and relinquished it to Yuan Shikai.
