Tanlis Mardates is among the least-documented rulers in the Indo-Parthian succession, known almost exclusively through his coinage rather than any surviving textual record. His issues with Raggodeme — likely a sub-king or regional co-ruler governing Aria or Margiana — reflect the fragmented administrative reality of the eastern Parthian fringe during the first century, where authority was routinely delegated across overlapping territorial claims.
The Aria/Margiana attribution remains unresolved in the scholarship, with Senior and Alram differing on precise provenance.
