How much of Britain and economy was dependent upon the slave trade?

The British economy in the 18th and early 19th centuries was significantly influenced by the slave trade, particularly through its connection to the sugar, tobacco, and cotton industries in the colonies. At its peak, the transatlantic slave trade accounted for a substantial portion of Britain's wealth, with estimates suggesting that it contributed to around 5% of Britain's national income at certain times. The profits from slavery helped finance industrialization, banking, and shipbuilding, making it an integral part of Britain's economic development during that era. However, the extent of dependence varied across regions and over time.
