Give me a title for this text:
The French and Indian War came to an end in 1763 with the signing of the Treaty of Paris, which was followed by the Proclamation of 1763. Due to their enormous debt from the war, the British government had to implement new laws in the occupied countries in order to curb colonial expansion and raise money. The proclamation specified boundaries for colonial settlement with the goal of fostering harmonious ties with Native American tribes. The colonists were irritated by the policy of restricting westward expansion because they believed it to be a breach of their natural rights and ambitions to possess property. Tensions between the American colonists and the British authority increased after the Proclamation of 1763.
