The nationalist struggles in Nigeria, spanning roughly the 1920s to 1960, produced several concrete political gains. One of the most significant was the formation of political parties. Nationalist leaders recognised that organised political platforms were essential to challenge colonial rule and negotiate constitutional advances.
Key parties that emerged from the movement include the Nigerian National Democratic Party (NNDP, 1923), the National Council of Nigeria and the Cameroons (NCNC, 1944), the Action Group (AG, 1951), and the Northern People's Congress (NPC, 1951). These parties gave Nigerians a formal vehicle for articulating demands, contesting elections introduced under successive colonial constitutions, and building the institutional framework for self-government.
The return of ex-servicemen after World War II was a catalyst for nationalism, not a gain of it. The independence of Ghana (1957) was an achievement of Ghanaian nationalism, not Nigerian. Problems of regionalism were a negative consequence of how politics developed, not a gain. Of the options given, the formation of political parties is the recognised positive outcome of Nigerian nationalist struggles.
