Islam
In Spain, Islam is represented, in both of its components, throughout the country. However, naturalised Islam is highest in the provinces of Andalusia where it has historical roots, Cordoba, Granada and Seville, and in the cities of Ceuta and Melilla, where Moroccan Muslims settled between 1960 and 1970, and through the Ley de Extranjería en España promulgated in 1985, they obtained Spanish citizenship.
Immigrant Islam is higher in the regions of Catalonia, Madrid and Andalusia where the first Muslim immigrant communities settled in the 80s.
The highest Muslim population densities are located, in decreasing order, in the provinces of Barcelona, Madrid, Murcia, Almeria, Gerona, Tarragona, Alicante and Malaga.
