Its mainland is bordered to the south and east by the Mediterranean Sea except for a small land boundary with Gibraltar; to the north and northeast by France, Andorra, and the Bay of Biscay; and to the west and northwest by Portugal and the Atlantic Ocean. It is the only European country to have a border with an African country (Morocco) and its African territory accounts for nearly 5% of its population, mostly in the Canary Islands but also in Ceuta and Melilla.  - Morocco (', lit. "The West"; '), officially known as the Kingdom of Morocco (', lit. "The Western Kingdom"; '), is a sovereign country located in the Maghreb region of North Africa.

All of which exacerbated by, a context of chaos that ensued a plague pandemic which left a third of the country dead, the end of the Anglo-Spanish war (Treaty of London (1604)) which broke the Anglo-Dutch axis that Morocco was relying upon as a means of protection from Spain, and so caused the Spanish navy to resume devastating raids on the Moroccan coast and the rebellion of one of his provincial governors who established his own independent republic between Azemmour and Salé.

Ahmad al-Mansur was an important figure in both Europe and Africa in the sixteenth century, his powerful army and strategic location made him an important power player in the late Renaissance period.  - Abu Faris Abdallah , nicknamed al - Wathik Billah ( 1564 -- 1608 ) was a ruler of the Saadi dynasty . He was one of the three sons of Ahmad al - Mansur and reigned in different parts of the country ( 1603 -- 1608 ) , the South , Marrakesh and Fez .
