Why is English Nigeria’s official language?

English is the official language of Nigeria primarily as a legacy of British colonial rule. During the period of colonial administration, the British government introduced and promoted the English language alongside Western education and administrative systems.123

Following the amalgamation of the northern and southern protectorates in 1914, English became the language of the central government and the colonial civil service. Because Nigeria is home to a vast array of indigenous languages—classified into the Niger-Congo, Nilo-Saharan, and Afro-Asiatic groups—English serves as a neutral, unifying medium for communication, governance, and education across the country's diverse ethnic and linguistic regions.312
