Lihyan
Lihyan (Arabic: لحيان, Liḥyān; Greek: Lechienoi), also called Dadān or Dedan, was an ancient Arab kingdom that played a vital cultural and economic role in the north-western region of the Arabian Peninsula and used Dadanitic language. The kingdom flourished for at least a century and a half, at some point between the 5th and 1st centuries BC. The Lihyanites ruled over a large domain from Yathrib in the south and parts of the Levant in the north.
