Two provinces, the County of Flanders and County of Artois, were originally French fiefs, but sovereignty was ceded to the Empire in the Treaty of Cambrai in 1529.
Kaks provintsi, Flandria krahvkond ja Artois' krahvkond, olid algselt Prantsuse läänid, kuid suveräänsus loovutati keisririigile Cambrai rahuga aastal 1529.
