William of Rubruck

William of Rubruck was a Flemish Franciscan friar who travelled across the Eurasian steppe to the Mongol Empire in 1253–1255 on a mission associated with Louis IX of France. He reached the court of Möngke Khan at Karakorum and produced an exceptionally detailed account of Mongol society, geography, religious debate and the many peoples living under imperial rule.

Rubruck’s journey provides historical fiction with a traveller whose observations are more cautious and exact than many medieval marvel tales. His account influenced Roger Bacon and remains valuable for reconstructing encounters among Latin Christians, Mongols, Muslims, Buddhists and eastern Christian communities. Fiction can use his mission to explore communication and misunderstanding without pretending that he travelled through an unknown or culturally empty world.
