Buscarello de Ghizolfi

Buscarello de Ghizolfi, also known as Buscarel of Gisolfe, was a European who settled in Persia in the 13th century while it was part of the Mongol Ilkhanate.

Arghun also promised that he would deliver Jerusalem to the Europeans if Egypt was successfully conquered:[6][7] Under the power of the eternal sky, the message of the great king, Arghun, to the king of France..., said: I have accepted the word that you forwarded by the messengers under Saymer Sagura (Bar Sauma), saying that if the warriors of Il Khaan invade Egypt you would support them.

[1] Buscarel made multiple other trips back and forth between the Ilkhanate and Europe, acting as an ambassador for various Mongol rulers in turn.

He represented Ghazan in 1303, carrying a message which reiterated Hulagu's promise that the Mongols would give Jerusalem to the Franks in exchange for help against the Muslim Mamluks.

[1] In 1303, the Mongols did attempt to invade Syria in great strength (about 80,000 troops), but were defeated at Homs on 30 March 1303, and at the decisive Battle of Shaqhab, south of Damascus, on 21 April 1303.

[6] Also, as had the previous Ilkhanate rulers, Oljeitu offered a military collaboration between the Christian nations of Europe and the Mongols against the Mamluks, but again, the attempts at forming an alliance were unsuccessful.
