What is "aldimir"

Aldimir or Eltimir ( fl. 1280–1305) was a Bulgarian noble of the 13th–14th century. A member of the Terter dynasty and a younger brother of Tsar George I Terter, Aldimir was an influential local ruler as the despot of Kran. Aldimir rose to that position under his brother George, though as Smilets assumed the throne he was forced into exile. At the turn of the 14th century, Aldimir returned to Bulgaria as an ally of the regent widowed consort Smiltsena. He did not oppose the accession of his nephew Theodore Svetoslav and even assisted him in ousting his contenders. However, he was promptly eliminated by Theodore Svetoslav when he betrayed him to ally with the Byzantines.
