Professor Griffiths's ongoing research lies in the broad field of politics and society in later medieval Britain. He is particularly interested in perceptions and relationships among the peoples of the British isles, the English monarchy and its dominions, the Lancastrian and Yorkist regimes in fifteenth-century politics, towns and the historic environment in Wales and the borderlands, and Anglo-Welsh society. He is also interested in nineteenth- and twentieth-century historiography of the Middle Ages.
