Gaykhatu
Gaykhatu ( Mongolian: Gaikhalt; Mongolian Cyrillic: Гайхалт, died 1295) was the fifth Ilkhanate ruler in Iran. He reigned from 1291 to 1295. During his reign, Gaykhatu was a noted dissolute who was addicted to wine, women, and sodomy, according to Mirkhond. His Buddhist baghshi gave him the Tibetan name Rinchindorj.
His name means "amazing/surprising" in the Mongolian language as in "gaikhakh" (to get surprised).
