1754 Albany Congress, Pennsylvania colonist Benjamin Franklin proposed the Albany Plan which would have created a unified government of the Thirteen Colonies for coordination of defense and other matters, but the plan was rejected by the leaders of most colonies. In the Treaty of Paris (1763), France formally ceded to Britain the eastern part of its vast North American empire, having secretly given to Spain the territory of Louisiana west of the Mississippi River the previous year. Before the war, Britain held the thirteen American colonies, most of present-day Nova Scotia, and most of the Hudson Bay watershed. Following the war, Britain gained all French territory east of the Mississippi River, including Quebec, the Great Lakes, and the Ohio River valley. Britain also gained Spanish Florida, from which it formed the colonies of East and West Florida.

The colonists' loyalty to the mother country was stronger than ever before. However, disunity was beginning to form. British Prime Minister William Pitt the Elder had decided to wage the war in the colonies with the use of troops from the colonies and tax funds from Britain itself. This was a successful wartime strategy but, after the war was over, each side believed that it had borne a greater burden than the other. The British elite, the most heavily taxed of any in Europe, pointed out angrily that the colonists paid little to the royal coffers. The colonists replied that their sons had fought and died in a war that served European interests more than their own. This dispute was a link in the chain of events that soon brought about the American Revolution.

They imposed several new taxes, beginning with the Sugar Act of 1764. Later acts included the Currency Act of 1764, the Stamp Act of 1765, and the Townshend Acts of 1767. Colonial newspapers and printers in particular took strong exception against the Stamp Act which imposed a tax on newspapers and official documents, and played a central role in disseminating literature among the colonists against such taxes and the idea
