Sukhrangpha
Sukhrangpha was the king of Ahom kingdom from 1332 CE to 1364 CE. He had to face the revolt led by his youngest brother Chao Pulai or Tai Sulai (there are confusion in Ahom historians whether Chao Pulai and Tai Sulai were same or different personality. Eventually he came in terms with Chao Pulai (or Tai Sulai) by appointing him as Charing Raja, a newly created official post to administer the region of Charing. Later the post of Charing Raja was usually conferred to the heir apparent to the throne. It can be compared with the title of Prince of Wales of England, where the heir apparent to the throne was conferred with this title.
