Eastern Arabia
Before the 7th century CE, the population of Eastern Arabia consisted of Christian Arabs, Zoroastrian Arabs, Jews, and Aramaic-speaking agriculturalists. Some sedentary dialects of Eastern Arabia exhibit Akkadian, Aramaic and Syriac features. The sedentary people of ancient Bahrain were Aramaic speakers and to some degree Persian speakers, while Syriac functioned as a liturgical language.
