What decree did King George III issue forbidding settlement west of the Allegheny Mountains?

The Proclamation of 1763 was a significant decree issued by King George III in response to the aftermath of the French and Indian War. This proclamation aimed to stabilize relations with Native American tribes by limiting colonial expansion into the lands west of the Allegheny Mountains. The British government recognized that uncontrolled settlement could lead to conflicts with Native Americans and sought to prevent further hostilities. The proclamation established a boundary line that forbade settlers from crossing into those western territories, thereby attempting to control colonial growth and manage relationships with indigenous peoples.

This decree is important in the context of colonial history as it was one of the first instances where the British crown attempted to regulate colonial expansion directly, and it contributed to growing tensions between the colonies and the British government, eventually leading to greater unrest and the push for independence.
