The indigenous pre-colonial Nigerian economy did not include oil mining. Prior to the arrival of Europeans, Nigeria had a thriving economy that was largely based on agriculture, crafts, and local industries. Agriculture was the backbone of the economy, with farmers producing a wide variety of crops such as yams, cassava, and maize. Craftsmanship was also an important part of the economy, with skilled artisans producing a range of goods such as textiles, pottery, and metalwork. Additionally, local industries such as mining and trade played a significant role in the economy, with people extracting minerals like tin and selling them in local and regional markets. Oil mining only became a major part of the Nigerian economy in the 20th century, following the discovery of oil reserves.
