Eastern Arabia
The Arab states of the Persian Gulf are solely Eastern Arabia, the borders of the Arabic-speaking Gulf do not extend beyond Eastern Arabia. The modern-day states of Bahrain, Kuwait, Oman, Qatar and UAE are the archetypal Gulf Arab states. Saudi Arabia is often considered a Gulf Arab state although most of the country's inhabitants do not live in Eastern Arabia with the exception of the Bahrani people who live in Qatif and al-Hasa oases and who historically inhabited the entire region of Eastern Arabia before the establishment of the modern day political borders.
