Why did the west African slave traders get their slaves to sell to europeans?

West African slave traders captured and sold slaves to Europeans primarily for economic gain. The transatlantic slave trade became a lucrative business, as European demand for labor in the Americas increased due to the expansion of plantations producing sugar, tobacco, and cotton. Local tribes and kingdoms often engaged in the trade to acquire goods such as firearms, textiles, and other valuables, further incentivizing the capture and sale of enslaved people. This exploitative system ultimately benefitted both the slave traders and European colonizers at the expense of countless individuals and communities.
