This chapter traces the extant historical literature on the growth and development of party politics in colonial Nigeria. These parties were led by formidable personalities who played an essential role in the formation of national consciousness crucial for the formation of an independent Nigeria. While historians have classified it into four phases, the chapter proposes that the growth of political parties should be analyzed into two generational periods: the 1920s and 1930s, and the 1940s and 1950s. The former period is marked by the promulgation of the Clifford Constitution that led to the creation of the first-ever nationalist parties, such as the Nigerian National Democratic Party and The Lagos Youth Movement which, though claiming nationalist status, was, however, confined to the Lagos area. The latter commenced after the enactment of the Richards Constitution which witnessed the growth of regional political parties such as the National Council of Nigeria and the Cameroons, the Northern People’s Congress, and the Action Group all of which espoused ethnic nationalism. By engaging with historical works produced on nationalist movements in colonial Nigeria, the chapter places their value beyond the simplistic teleological development of politics of nationalism in Nigeria.
