Aïbeg and Serkis
（重定向自Sergis）
- Aïbeg and Serkis, also Aibeg and Sergis or Aïbäg and Särgis, were two ambassadors sent by the Mongol ruler Baichu to Pope Innocent IV in 1247–1248. They were the first Mongol envoys to Europe.
Aïbeg ("Moon Prince") is thought to have been a Turcophone Christian, possibly Uighur, and Sergis (from the Roman and later Christian name "Sergius" or "Sarkis") a Nestorian Christian, probably Assyrian. Both were sent by Baichu, to accompany the 1245 embassy of the Dominican Ascelin of Lombardia back to Lyon, France, where the Pope was residing at the time. They stayed there for about a year.
