During the mid 1700s, Britain was making great efforts to strengthen its global naval supremacy. In order to prep and increase their chances of success in the 7 years war, alliances were formed between Britain and Prussia as well as France and Austria. Initially, it seemed that France had the advantage over the rest as they had an additional alliance with the First Nations’ natives. However, they made the costly mistake of leaving their colonies to fend for themselves while the majority of their troops were fighting battles in Europe. Thus, while the battle on the Plains of Abraham was taking place, the french fleet was decimated by two other battles in Lagos, Portugal and Quiberon Bay, France. This opened up the door of opportunity for the British to gain naval supremacy on the Atlantic Ocean and cut off the supply lines to the French troops in New France. Without any weapons or food, the French troops had no choice but to surrender and sign the Treaty of Paris, officially ending the French-Indian War. One of the major impact of the war was the huge debt that followed after. In order to elevate the debt and recoup their losses, Britain introduced the Royal Proclamation in 1763. This document sought to limit land claims and settlement of Western territories, partly to avoid conflict with Native American tribes there.
