The correct answer is "self-determination." The Proclamation Line of 1763 was a boundary set by the British government in an attempt to limit westward expansion by the American colonists. It prohibited settlement beyond the Appalachian Mountains to maintain control over the territories acquired from France after the French and Indian War. However, the American colonists were determined to have the freedom to expand and govern themselves. Consequently, when they achieved independence from Britain during the American Revolution, the Proclamation Line of 1763 was rendered void as it no longer had the authority to restrict their actions.
