Answer:
Granada
Explanation:
The part of Muslim Spain that resisted the Christians the longest is GRANADA.
Following the rule of Muslims in Spain for over 700 years, the Christians began to conquer the Muslim states in the Iberian peninsula particularly modern-day Spain.
In the period known as Reconquista around the 13th century, it was only Granada that remains out of all the city-states being ruled by the Muslims. Granada eventually falls during the Granada war in the late 15th century.
