6 Dirhams - 'Ilkhan' Uljaytu Khan Type C

Uljaytu — born Nicholas at his Nestorian Christian baptism, later Buddhist, then Sunni, then Shia — converted to Twelver Shia Islam around 1309–1310, a decision that sent shockwaves through the Ilkhanate and prompted him to replace the names of the first three Sunni caliphs on his coinage with those of the Twelve Imams. The resulting sectarian uproar was severe enough that he partially reversed course before his death in 1316, leaving the coinage of his reign a documentary record of his theological wandering.

Type C falls within this volatile middle period. The shift in religious formulae across Uljaytu's die sequences makes attribution to specific mint and regnal year critical for any serious study of his numismatic output.
