What happened
In 1956, after decades of exploration that began with an exclusive license granted to Shell D'Arcy in 1937, Shell-BP made Nigeria's first commercially viable oil discovery at Oloibiri, in what is now Bayelsa State in the Niger Delta. The find ended fifty years of unsuccessful prospecting hampered by poor infrastructure and the Delta's swampy, difficult terrain. By 1958, the first barrels of Nigerian crude oil were exported, just two years before independence. Government revenue from oil grew enormously over the following decades: annual federal revenue rose from around 590 million dollars in 1965 to roughly 5 billion dollars by 1976, by which point Nigeria had become the world's seventh-largest oil producer, exporting two million barrels of crude a day.
Why it matters
Oil transformed Nigeria's economy from one based on agricultural exports into a petrostate whose government budget depends overwhelmingly on crude revenue, a shift that took hold in the same decade the country gained independence and endured its first coups. That dependence concentrated enormous wealth in the hands of whichever government or military faction controlled the state, while communities in the oil-producing Niger Delta itself saw comparatively little of the benefit, a tension that has fed decades of Delta unrest.
How we know
The 1956 Oloibiri discovery and its production timeline are documented in the official history maintained by Nigeria's Federal Ministry of Petroleum Resources, and the resulting growth in oil revenue is independently confirmed through national budget figures analyzed by international policy institutions.
