British prime minister that passes American revenue act in 1764?

The British Prime Minister who was in office when the American Revenue Act, also known as the Sugar Act, was passed in 1764 was George Grenville. The act aimed to reduce the previously high tax on molasses imported into the colonies and enforce stricter measures against smuggling. Grenville's policies, including the Sugar Act, were part of a broader effort to generate revenue from the American colonies to help pay off debts from the French and Indian War. This act contributed to growing tensions between Britain and the American colonies, eventually leading to the American Revolution.
