Some of the associations decided to re-align. The People's Front of Nigeria, People's Solidarity Party and the Nigerian Labor Party were the three main inchoate groups that emerged to form the core constituency of the new SDP. The leadership of the party was mostly dominated by Northern Nigerians, with Babagana Kingibe elected party chairman in 1990 over his rival Mohammed Arzika. On the other hand, the electoral strength of the party lain in the Yoruba states and Imo and Anambra states. The party won 57% of the Senate seats in the 1992 National Assembly election, and won 53% of the seats of the House of Representatives in the same election. The party was largely financed by the Federal Government and a few individuals, such as Shehu Musa Yar'Adua, Francis Nzeribe and M.K.O. Abiola. The first presidential primary election conducted by the party, Yar'adua collated about 480,000 votes dominating his primary opponent, Olu Falae in the first round. However, those elections were cancelled by Babangida. In second primary election under an adopted system called Option A4, another financier, Abiola (a former member of the National Council of Nigeria and the Cameroons and once a state chairman of the National Party of Nigeria) won the primary election on March 1993, after the first election was canceled.

Nationalism has also led to active secessionist movements such as MASSOB, Nationalist movements such as Oodua Peoples Congress, Movement for the Emancipation of the Niger Delta and a civil war. Nigeria's three largest ethnic groups (Hausa, Igbo and Yoruba) have maintained historical preeminence in Nigerian politics; competition amongst these three groups has fuelled corruption and graft.
