Uljaytu's reign saw one of the more consequential religious pivots in Ilkhanid history — he converted from Buddhism to Christianity to Sunni Islam before finally settling on Twelver Shi'ism in 1309, a shift that briefly made the Ilkhanate the only Mongol successor state with a Shi'a ruling house. Copper fals of this reign are chronically difficult to attribute precisely because the administration issued such quantities across a fragmented mint network, with many pieces remaining either unpublished or catalogued only through private collection data like the Zeno corpus.
