Action Congress of Nigeria

The Action Congress of Nigeria (ACN), formerly known as Action Congress (AC), was a Nigerian political party formed via the merger of a faction of Alliance for Democracy, the Justice Party, the Advance Congress of Democrats, and several other minor political parties in September 2006. The party controlled Lagos. It was regarded as a natural successor to the progressive politics more closely associated with the Action Group and Unity Party of Nigeria (UPN) led by Chief Obafemi Awolowo in the First and Second Republics respectively. However, criticism of the party's more pragmatic and less ideological political outlook associated with AG and UPN, has made many argue it was less of a worthy political heir. The Party had strong presence in the South West (5 Governors, 15 Senators and 6 State Houses), Mid-West (1 Governor) and North Central Regions (3 Senators). Lagos, Edo, Ekiti, Kogi, Ondo, Bauchi, Plateau, Niger, Adamawa, Oyo and Osun states by far accounts for majority of the party's presence and discernible power base.

In February 2013 the party merged with the Congress for Progressive Change, the All Nigeria Peoples Party, and the All Progressives Grand Alliance to form the All Progressives Congress.
