How did the postwar oil boom strengthen Nigeria’s federal government?

Following the Nigerian Civil War, the postwar oil boom provided the federal government with the financial resources necessary to consolidate its authority and implement various development programs.12

By generating significant revenue, the petroleum industry allowed the central government to expand its influence and fund national initiatives, which helped strengthen its position relative to the regions. This economic influx, particularly following world oil price increases in the 1970s, fueled rapid growth in sectors such as construction, manufacturing, and government services, further centralizing the role of the federal government in the nation's economy.123
