The sedentary people of pre-Islamic Eastern Arabia were mainly Aramaic, Arabic and to some degree Persian speakers while Syriac functioned as a liturgical language. In pre-Islamic times, the population of Eastern Arabia consisted of Christianized Arabs (including Abd al-Qays), Aramean Christians, Persian-speaking Zoroastrians and Jewish agriculturalists. According to Robert Bertram Serjeant, the Baharna may be the Arabized "descendants of converts from the original population of Christians (Aramaeans), Jews and ancient Persians (Majus) inhabiting the island and cultivated coastal provinces of Eastern Arabia at the time of the Arab conquest". Other archaeological assemblages cannot be brought clearly into larger context, such as the Samad Late Iron Age.
