The Proclamation of 1763 was a document issued by King George III of Great Britain following the British victory in the Seven Years' War. The proclamation had a number of effects on the American colonies:
- It established a boundary line along the Appalachian Mountains. This line was intended to prevent colonists from settling in the Ohio River Valley, which the British considered to be Indian territory.
- It required all colonists who had settled west of the Appalachian Mountains to move back east. This provision was unpopular with the colonists, who had already invested a great deal of time and money into developing their new settlements.
- It imposed a new tax on all goods imported into the colonies. This tax was also unpopular with the colonists, who felt that they were being taxed without their consent.
These provisions of the Proclamation of 1763 were widely resented by the colonists, and helped to fuel the growing movement for independence from Great Britain.
