After the founding of the Republic of China in 1912, a plethora of parties appeared to compete for the upcoming National Assembly elections. The four largest winners were the Nationalist Party representing revolutionaries, the Republican Party representing militarists, the Unity Party representing the gentry, and the Democratic Party representing former constitutional monarchists. The latter three merged to form the Progressive Party in 1913. After the failed Second Revolution against Yuan Shikai, the Nationalist leadership fled China and regrouped as the Chinese Revolutionary Party. The Progressives were split into pro- and anti-Yuan factions during the National Protection War.
