Battle of Hamar

The Battle of Hamar (also known as Siege of Hamar) was a short siege that lasted for three days in late June of 1537, between the forces of Catholic bishop Mogens Lauritssøn and nobel Truid Ulfstand. Truid Ulfstand came down from Trondheim to arrest the bishop as a part of the Reformation in Denmark–Norway and Holstein. The bishop heard that he was going to be arrested and barricade him and his men innside his farm at Hamar before the Protestant troops came. When the Protestant troops came they laid siege to the farm. The commander of the Protestant forces had a parley with the bishop, and gave him three days to surrender or he would burn the farm. On the third day of the siege. The Bishop surrenders and is taken as a prisoner to Denmark where he dies.

The siege was one of the last stands against the reformasjon in Norway, and the Norwegian riksråd was abolished and the king of Denmark-Norway became the biggest landowner in Norway after confiscating church land.
