In page Bourges:

"

During the Middle Ages, Bourges served as the capital of the Viscounty of Bourges until 1101. In the fourteenth century, it became the capital of the Duchy of Berry (established in 1360). The future king of France, Charles VII (r. 1422–1461), sought refuge there in the 1420s during the Hundred Years' War. His son, Louis XI, was born there in 1423. In 1438, Charles VII decreed the Pragmatic Sanction of Bourges. During this period, Bourges was a major centre of alchemy.[citation needed] In 1487, a third of Bourges was destroyed by fire, after which the economic decline of the city started.[3]
