The All Progressives Congress (APC) is a centrist political party in Nigeria, founded on 6 February 2013. The party united the Action Congress of Nigeria, Congress for Progressive Change, and the All Nigeria Peoples Party, the three biggest opposition parties in the country, with the goal of blocking the People's Democratic Party of Nigeria's ability to pass legislation. The All Progressives Congress had numerous factions, with the majority of its members supporting social conservatism and progressivism, and a minority of APC members supporting social liberalism and social democracy. The party was a consultative member of Socialist International due to its center-left economic views.
The party won the 2015 elections, and the APC presided over the first peaceful transition of power in Nigerian governmental history, unseating the ruling party without the use of violence. However, the party was unable to block all of the PDP's legislation, as it lacked an absolute majority in the parliament. The party had center-left economic views and right-wing social views; it supported controlled market economic policies, strong government regulations, and social conservatism. In 2017, the APC held 225/360 House of Representatives seats, 60/109 Senate seats, and 22/36 governorships.
