The Triple Alliance was the association of Tenochtitlan, Texoco, and Tlacopan, three city states in Central Mexico that came together in the early 1400s CE. This association ruled over much of central Mexico for the next hundred years, with authority vested in the king of Tenochtitlan, although most associated city states had some authority. When Hernan Cortes first encountered and then conquered the Alliance in the early sixteenth century, he and his fellow Spaniards related to it as an "Empire," which they named after the largest ethnic group in the Alliance, the Azteca.

The Seven Years' War was fought between England and France from 1756 to 1763. In the United States, the conflict is more commonly called the French and Indian War. The conflict had many direct consequences across the globe, notably the British gaining the Indian subcontinent from France, the reduction of French influence in North America, and deteriorating relationships between the American colonies and Britain. Many colonists resented the British imposition of taxes, tariffs, and quartering laws, whereas in Britain many people felt that the war had been fought in part to protect the colonists from French and Native American invasion, and therefore the colonists ought to help pay for the conflict. The relationship between the colonies and the metropole would never heal, and the build-up of tension eventually led to the American War of Independence, also called the American Revolutionary War.
