After the establishment of the Republic of China, the Tongmenghui transformed itself into a political party on 3 March 1912, in preparation for participation in constitutional and parliamentary activities. It issued a Provisional Constitution of the Republic of China, which consisted of 34 articles, meaning it had 10 more than the constitutional proposal made when the Tongmenghui was a secret society. The leadership election was held on the same day, with Sun Yat-sen elected as Chairman, Huang Xing and Li Yuanhung as Vice-Chairmen.
