State elections and three parties emerge

In January 1999, Nigeria held state-level elections that crystallized the political landscape of the emerging Fourth Republic. Three major parties dominated the contests: the People's Democratic Party (PDP), the Alliance for Democracy (AD), and the All People's Party (APP). The elections saw the PDP winning control of most states across the country, while the AD established itself as the dominant force in the Yoruba-speaking Southwest, and the APP secured victories primarily in northern states.

These elections followed nearly sixteen years of military rule and represented the final stage of General Abdulsalami Abubakar's transition program back to civilian government. The military government had lifted the ban on political activities in 1998 and registered these three parties from among numerous applicants. The state elections served as a crucial test run before the presidential election scheduled for February 1999, allowing parties to demonstrate their organizational capacity and regional appeal while giving voters their first opportunity to participate in democratic governance since 1983.
