The Sugar Trade and cotton were the main reasons for the Triangular Trade. The British demanded high amounts of sugar for tea, food, and other goods, the more they needed the more the workers were needed to obtain this high quantity of sugar. So the British started bringing slaves to the British Caribbean and the Colonies. The colonies and the Caribbean out put sugar and tobacco and cotton. While the British supplied rum, textiles (clothes, shoes, etc.) and other manufactured goods to the African slaves. It was just a revolving door after that, the process would start over.
