Some of these tribes were dominating others, but they all, as a matter of course, suffered certain discriminatory measures (cf. infra) under both the Rai and Brahman dynasties and the Arabs. The territories of the Lohana, Lakha and Samma are also described as separate jurisdictions under the governor of Brahmanabad in the pre-Muslim era. Whatever may be the original distinction between Samma and Jat - the two tribes from which the majority of Sindhis descend - , in later times it became completely blurred and the same people may be classed as Samma and Jat.
