Eastern Arabia
Before the 7th century CE, the population of Eastern Arabia consisted of partially Christianized Arabs, Arab Zoroastrians, 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.
