Llywelyn ap Iorwerth ruled as Prince of Gwynedd and, at the height of his power, as the dominant force in Wales. He outlasted enemies, outmanoeuvred the English crown, and built a political legacy that would shape Welsh identity for generations. This free illustrated guide brings his story together in one place, formatted as a portrait poster you can print at home or at any print shop.
The guide covers the key moments of Llywelyn's life and reign, from his consolidation of power in northern Wales to his relationships with the English barons and his role in the events surrounding Magna Carta. It is illustrated throughout and designed to be as useful on a wall as it is in hand.
