The Audumbras, or Audumbaras (Hindi;ओदुम्बर) were a north Indian tribal nation east of the Punjab, in the Western Himalaya region.

They were the most important tribe of the Himachal, and lived in the lower hills between Sirmaur, Chamba and Yamuna.

Kotesvara was a celebrated place of pilgrimage on the western shore of Kachh, close to Indus and to the great ocean.

The word Rann is evidently a corruption of Irana, which means a salt land (Amarkosha).

It was also known as Dahmeri, Dhamari, Dhammeri etc., which is apparently a corruption of Sanskrit name Audumvara of the country and tribe, whose coins have been found in Kangra (In Himachal Pradesh), Pathankot, Ropar and Hoshairpur (Punjab).

The Prakrit legends Aduinvarisa – ‘of the Audumvara’ appears on the copper coins and pieces of Audumbara tribe in Punjab.

It appears that a section of Audumvara tribe migrated to Gujarat, may be due to internal conflict or some aggression.
