Owain Glyndwr (died c. 1416) was the last Welshman to hold the title of Prince of Wales. In 1400 he led a rebellion against king Henry IV and English rule in Wales. In 1406 he addressed a letter, now known as the Pennal Letter, to king Charles VI of France asking for support in persuading the schismatic pope Benedict XIII to help Wales to exist as an independent state with a Church and universities of its own.

This chapter focuses on narrative texts from Wales largely comprising annals, chronicles and histories composed from the twelfth to the fifteenth century and situates these in their cultural, political and social contexts. After identifying key themes of the historical culture evidenced, for example, by poetry, prose tales and genealogy, the discussion highlights the significance of Geoffrey of Monmouth in the development of medieval Welsh historical writing and compares his work with other Latin histories from twelfth-century Wales. It then considers the vernacular chronicles known as Brut y Tywysogion (The History of the Princes) whose coverage extends from the late seventh century to the eve of the Edwardian conquest of 1282. While based on Welsh-Latin chronicles, these were intended as a continuation of Geoffrey, and from the fourteenth century are associated in some manuscripts with Welsh translations both of his History and of Dares Phrygius’ account of the Trojan War.
