Formed in February 2013, the party is the result of an a merger of Nigeria’s three biggest opposition parties – the Action Congress of Nigeria (ACN), the Congress for Progressive Change (CPC), the All Nigeria Peoples Party (ANPP) – and a faction of the All Progressives Grand Alliance (APGA). The three political parties organized their conventions and passed resolutions giving the go ahead to forgo their individual identities and merge into one big party, the All Progressives Congress (APC).
The party received approval from the nation’s electoral umpire Independent National Electoral Commission (INEC) on 31 July 2013 to become a political party and subsequently withdrew the operating licenses of the three legacy parties (the ACN, CPC and ANPP).
In March 2013, it was reported that two other associations – African Peoples Congress and All Patriotic Citizens – also applied for INEC registration, adopting APC as an acronym as well, reportedly “a development interpreted to be a move to thwart the successful coalition of the opposition parties, ahead of the 2015 general elections.” It was reported in April 2013 that the party was considering changing their name to the All Progressive Congress of Nigeria (APCN) to avoid further complications.
In November 2013, five serving Governors, along with Alhaji Atiku Abubakar, former vice president of Nigeria, from the governing PDP defected to the APC, as well as 49 legislators who joined the ranks of 137 legislators in the APC as a result of the prior merger of the smaller opposition parties.
This initially gave the APC a slim majority of 186 legislators in the Lower House out of a total of 360 legislators; however, subsequent political wrangling and pressure from political factions and interests outside the National Assembly of Nigeria, gave the party only 37 additional legislators thus giving the APC a nominal majority of 172 out of 360 Legislators, as opposed to the PDP’s 171 (though some smaller PDP-allied parties hold the balance of the other seats.
This was further confirmed when the party seated 179 members on January 15, 2015 when the House resumed after a long recess to finally affirm its majority. The governors who defected to the APC were Rotimi Amaechi of Rivers State, Abdulfatah Ahmed of Kwara State, Rabiu Kwankwaso of Kano State, Murtala Nyako of Adamawa State and Aliyu Wamakko of Sokoto State. It had been previously reported that Governors Mu’azu Babangida Aliyu of Niger State and Sule Lamido of Jigawa State were to set to defect from the People’s Democratic Party to the APC; however, both ended up remaining with the People’s Democratic Party.
In the 2015 elections, Mu’azu Babangida Aliyu ran as a senatorial nominee of the People’s Democratic Party for the Niger State east senatorial district, losing in a landslide to the APC’s David Umaru.
