Arthur II, Duke of Brittany

Arthur II (25 July 1261 – 27 August 1312), of the House of Dreux, was Duke of Brittany from 1305 to his death. He was the first son of John II and Beatrice, daughter of Henry III of England and Eleanor of Provence.

After he inherited the ducal throne, his brother John became Earl of Richmond.

As duke, Arthur was independent of the French crown. He divided his duchy into eight "battles": Léon, Kernev, Landreger, Penteur, Gwened, Naoned, Roazhon, and Sant Malou. In 1309, he convoked the first Estates of Brittany. It was the first time in French history that the third estate was represented.

Arthur died at Château de l'Isle in Saint Denis en Val and was interred in a marble tomb in the Cordeliers Convent at Vannes. The tomb was vandalised during the French Revolution, but later repaired and is on display today.
