Answer: Letters granting special privileges and liberties
Explanation:
Fuero in Moorish Spain was a municipal franchise granted to a community by the Crown or a Bishop or Nobel which granted legal status such as CONFIRMATION OF LOCAL CUSTOMS, RIGHTS TO TAXATION AND SELF GOVERNANCE, etc.
The Various Christian Kings during the Christian reconquest of Spain from the Muslims, granted these Fueros to provide incentives to settlers to take over land especially those far from the crown.
More than 800 Fueros we're granted between the 11th and 14th century.
