What was one reason for the growth of the democratic slave trade?

One reason for the growth of the transatlantic slave trade was the increasing demand for labor in the Americas, particularly in the agricultural sector. The establishment of cash crops like sugar, tobacco, and cotton required a large workforce, which led plantation owners to seek enslaved Africans as a more profitable and controllable labor source compared to indentured servants. Additionally, advancements in maritime technology and the establishment of trade networks facilitated the transportation of enslaved individuals across the Atlantic.
