In 1905, together with Sun Yat-sen, Song helped to found and was a leading activist in the "Tongmenghui", which was an organization dedicated to the overthrow of the Qing dynasty and the formation of a republic. Song returned to China in 1910 after the Xinhai Revolution and traveled to Hong Kong the next year to organize the Second Guangzhou Uprising. After the 1912 declaration of the Republic of China, Song helped to transform the "Tongmenghui" into the Kuomintang, also known as the KMT or Chinese Nationalist Party.
