King George III did not agree to the colonists' demands due to the insufficiency of the Conciliatory Proposition presented by Prime Minister Lord North, which failed to meet colonial expectations. This disagreement led to escalating tensions and confrontations between the colonies and Britain.
King George III did not agree to the colonists' demands primarily because the provisions offered by the British, such as taxing to regulate trade and emphasizing individual colonies' defense responsibilities, fell short of colonial expectations. The Conciliatory Proposition presented by Prime Minister Lord North was the extent to which Parliament was willing to meet the American demands.
These proposals, viewed as reasonable by the British, were far from satisfactory for the colonies. Consequently, the Second Continental Congress faced both an unsatisfactory response and British 'aggression' at Lexington and Concord, leading to the escalation of tensions between the colonies and Britain.
