Date: July 12, 1971.
Nigeria officially joined the Organization of the Petroleum Exporting Countries (OPEC) on July 12, 1971. As Africa’s largest oil producer, Nigeria’s membership in OPEC marked a significant step in strengthening its influence in the global oil market.
The reason for joining is to align with other oil-producing nations in regulating oil production, stabilizing prices, and ensuring a fair return on petroleum exports.
