George Grenville was the British Prime Minister from 1763-1765. To obtain funds for Britain after the costly 7-Years War, in 1763 he ordered the Navy to enforce the unpopular Navigation Laws, and in 1764 he got Parliament to pass the Sugar Act, which increased duties on sugar imported from the West Indies. He also, in 1765, brought about the Quartering Act, which forced colonists to provide food and shelter to British soldiers, who many colonists believed were only present to keep the colonists in line. In 1765, he imposed the Stamp Act, which put taxes on everything from newspapers to marriage licenses. These measures disgruntled the colonists, created anger towards the mother country, unified them, and helped provide the beginnings of the American Revolution.
