Arghunid

The Arghunids were the family of the Mongol amirs Arghun Aqa, his son Nawrūz and his grandson Arghun Shah, who led the Ja'un-i Qurban, a Mongol military tribe in Khorasan. After the Ilkhanate collapsed in 1335, Arghun Shah became the chief supporter and commander of the claimant Togha Temür, ruling from Nishapur over Tus, Mashhad and the Atak frontier.

In 1337 he crushed the Jalayirid-backed governor Muhammad Mulai, but the Sarbadars seized Nishapur in 1340 and forced him back to Tus. Arghun Shah died in 1345 or 1346; his son Muhammad Beg abandoned Togha Temür and allied with the Sarbadars. The tribe later submitted to Timur around 1381 and joined the failed revolt of Hajji Beg at Tus in 1389.
