Nigeria joined the Organisation of Petroleum Exporting Countries (OPEC) in__________

Nigeria joined the Organisation of Petroleum Exporting Countries (OPEC) in 1971. OPEC is a group of oil-producing countries that work together to manage the supply and price of oil. By joining OPEC, Nigeria became a part of this group and agreed to coordinate with other member countries to help regulate the oil market. This means that Nigeria would limit its own oil production to support the stability of oil prices globally. Joining OPEC was an important decision for Nigeria, as the country is one of the largest oil-producing nations in the world and oil exports play a significant role in its economy. By being a part of OPEC, Nigeria has a voice in the global oil market and can work to protect its own interests and those of other oil-producing countries.
