Prester John

Lore & Background

The origin of the idea of Prester John originates from a letter that began circulating around 1165, often addressed to various rulers including Byzantine emperor Manuel I Komnenos. The sender was: 'John, Christian Sovereign and Lord of Lords'. The letter described the very rich lands of this monarch located in central Asia. The king said he lived in an immense palace made of gems and gold and said he governed a huge territory extending from Persia to China.

For many years the idea of Prester John was associated with the dream of reaching a sumptuous kingdom, where all material pleasures were fulfilled and people lived in opulence. The legend drew strongly from earlier accounts of the Orient and of Westerners' travels there, particularly the reports of Saint Thomas the Apostle's proselytizing in India, recorded in the third-century work known as the Acts of Thomas. This text inculcated in Westerners an image of India as a place of exotic wonders and offered the earliest description of Saint Thomas establishing a Christian sect there.

Embellished reports of movements in Asia of the Church of the East (Nestorianism) informed the narratives as well. French historian René Grousset suggests that the Prester John story may have had its origins in the Kerait clan, which had thousands of its members join the Church of the East shortly after the year 1000. By the 12th century, the Kerait rulers were still following a custom of bearing Christian names, which may have fueled the narrative.

German chronicler Otto of Freising reported in his Chronicon of 1145 that the previous year he had met Hugh, bishop of Jabala in Syria, at the court of Pope Eugene III in Viterbo. Hugh told Otto, in the presence of the pope, that Prester John, a Nestorian Christian who served in the dual position of priest and king, had regained the city of Ecbatana from the brother monarchs of Media and Persia, the Samiardi, in a great battle 'not many years ago'.

Afterwards Prester John allegedly set out for Jerusalem to rescue the Holy Land, but the swollen waters of the Tigris compelled him to return to his own country. His fabulous wealth was demonstrated by his emerald scepter; his holiness by his descent from the Three Magi.

Reader's Guide

In the Crusader Kings universe, Prester John represents a tantalizing mystery rather than a direct ruler on the map. Players will encounter his name primarily through event chains and diplomatic flavor text that reflect historical medieval legends. Rulers across Europe often dream of securing an alliance with this mythical Christian monarch believed to rule over vast lands in Asia or Africa. This figure embodies the hope for a second front against Islamic powers during the Crusades, a central theme in many gameplay scenarios involving religious warfare.

The game incorporates this lore by occasionally sending letters from Prester John to your court, offering potential aid or simply stirring intrigue about the wider world beyond your borders. These events serve as reminders that the medieval mindset was filled with rumors of lost kingdoms and powerful allies waiting in the East. While he does not typically appear as a standard playable character, his legend influences the historical context surrounding regions like Ethiopia and India.

Understanding this lore helps players appreciate the depth of the game's world-building, where history blends seamlessly with the myths that shaped the medieval imagination.
