Terminology

In page 9 of Best Divisions for Knowledge of the Regions, 10th century Arab geographer Al Maqdisi used the term Arab regions (Arabic: أَقَالِيمُ ٱلْعَرَبِ) to refer to the lands of the Arabian Peninsula (Bahrain, Iraq, Jordan, Kuwait, Oman, Qatar, Saudi Arabia, United Arab Emirates and Yemen). He also considered Iraq, alongside Upper Mesopotamia (Iraq, Syria and Turkey), Ash-Sham (Israel, Jordan, Lebanon, Palestine, Syria and Turkey), Egypt and the Maghreb (Algeria, Libya, Mauritania, Morocco, Tunisia and Western Sahara Sahrawi Arab Democratic Republic) to be part of the Arab regions.

Malta, an island country in Southern Europe whose national language derives from Arabic (through Sicilian Arabic), is not included in the region. Similarly, Chad, Eritrea and Israel recognize Arabic as one of their official or working languages but are not included in the region because they are not members of the Arab League.
