Berry
Berry was a French duchy centred on Bourges, granted as an appanage to junior members of the royal family. In 1360 John II raised Berry to a duchy for his son John, who spent the following years as a hostage in England under the Treaty of Brétigny.
John returned to France in 1369 and served as a regent during the minority of Charles VI from 1380 to 1388. He also commissioned illuminated manuscripts, including the Très Riches Heures; later French monarchs granted the title to other members of their families.
