Title:
French_and_Indian_War

Context:
The War of the Austrian Succession (whose North American theater is known as King George's War) formally ended in 1748 with the signing of the Treaty of Aix-la-Chapelle. The treaty was primarily focused on resolving issues in Europe. The issues of conflicting territorial claims between British and French colonies in North America were turned over to a commission to resolve, but it reached no decision. Frontiers from between Nova Scotia and Acadia in the north, to the Ohio Country in the south, were claimed by both sides. The disputes also extended into the Atlantic Ocean, where both powers wanted access to the rich fisheries of the Grand Banks off Newfoundland.
