Postage stamps and postal history of Norway

The postal system of Norway dates from 1647, when Christian IV of Denmark–Norway granted a concession to a private company who established the Postvesenet (now Posten Norge). The Postvesenet primarily provided a way for various parts of the country to communicate with the central government in Christiania (spelled Kristiania from 1877; renamed Oslo in 1925).
