Arab dynasties originating from modern-day Saudi Arabia founded the Rashidun (632–661), Umayyad (661–750), Abbasid (750–1517) and the Fatimid (909–1171) caliphates as well as numerous other dynasties in Asia, Africa and Europe.
The area of modern-day Saudi Arabia formerly consisted of mainly four distinct regions: Hejaz, Najd and parts of Eastern Arabia (Al-Ahsa) and Southern Arabia (‘Asir). The Kingdom of Saudi Arabia was founded in 1932 by Ibn Saud.
