The Albany Plan of Union was a rejected plan to create a unified government for the Thirteen Colonies at the Albany Congress on July 10, 1754 in Albany, New York. The plan was suggested by Benjamin Franklin, then a senior leader and a delegate from Pennsylvania. Franklin spent much time among the Iroquois observing their deliberations and pleaded with the colonial leaders to consider the plan. More than twenty representatives of several Northern Atlantic colonies had gathered to plan their defense related to the French and Indian War (1754–1763), the front in North America of the Seven Years' War between Great Britain and France, spurred on by George Washington's recent defeat in the Ohio valley. The Plan represented one of multiple early attempts to form a union of the colonies "under one government as far as might be necessary for defense and other general important purposes." The plan was rejected but it was a forerunner for the Articles of Confederation and the United States Constitution.

The Thirteen Colonies were a group of British colonies on the Atlantic coast of North America during the 17th and 18th centuries. Grievances against the imperial government led the 13 colonies to begin uniting in 1774, and expelling British officials by 1775. Assembled at the Second Continental Congress in Philadelphia, they appointed George Washington as commander-in-chief of the Continental Army to fight the American Revolutionary War. In 1776, Congress adopted the Declaration of Independence as the United States of America. Defeating British armies with French help, the Thirteen Colonies gained sovereignty with the Treaty of Paris in 1783.
