Acadia was claimed by the French, who had explored and occupied it periodically since 1524, following the expedition of Giovanni da Verrazzano. However, the English also considered this land to be theirs, in accordance with the charter drawn up in 1606 by James I, which granted to the Virginia Company a territory that extended to the 45th parallel and thus included La Baie Française (Bay of Fundy) and Port Royal. The lack of clear boundaries was a source of endless conflict between France and England, as well as numerous clashes between French settlers and their New England neighbours. Neither the Treaty of Utrecht (1713), nor the Treaty of Aix-la-Chapelle (1748) were able to define the borders of Acadia more precisely. Although France and England studied the problem in the 1750s; only war would put an end to these discussions.
