 While Aranese is the mother tongue of 62.87% of people born in the region, it is less frequent among residents born outside the valley.In 1313, James II of Aragon granted administrative and political autonomy to the Aran Valley, the legal details of which are described in a Latin manuscript called the Querimonia.The devolution of power was a reward for the Aranese pledging allegiance to James II in a dispute with the kingdoms of France and Mallorca over control of the valley.
