Historical Dictionary of Morocco (3rd ed.)

A historical reference work on Morocco must take as its subject al-maghrib al-aqsa (the far west) as the Arabic scholars have generally referred to the approximate region of present-day Morocco, roughly the north-west corner of Africa but at times including much of the Iberian peninsula, because the modern nation-state is a relatively recent creation owing much to events in the late 19th and early 20th centuries. External influences on Morocco tend to come across the narrow straits of Gibraltar
