Norby was of poor
Funen nobility, For his success in the war, Norby was rewarded with
Börringe Priory in
Scania and also owned Haraldsborg near
Roskilde. Under new King
Christian II of Denmark, Norby was sent as leader of a fleet to aid
Charles II of Burgundy against
Geldern in 1514. and his
blockade of Stockholm helped Christian II secure the Swedish throne in 1520. Norby helped make arrests during the
Stockholm Bloodbath, but is said to have rescued many Swedes by sailing them out of Stockholm. He was then granted
Kalmar Castle. Norby was tasked with finding a sea route to the
West Indies via
Greenland, but had to abandon his plans due to the rise of
Gustav Vasa who was crowned King of Sweden in 1521. In the following years, Norby lost his possession of Öland, but was granted
Finland and
Norrbotten. When Christian II abdicated under great pressure in April 1523, Norby was the only seignory who stayed loyal to him. Norby lost Kalmar and Finland that year, and fortified himself at Visborg. He was isolated and began
minting his own coins in order to pay his men, bearing the name insignia
Severin Norbi. He negotiated with both the new Danish king
Frederick I, Sweden, and Lübeck to keep his possession of Visborg. After diplomatic machinations, Norby eventually stayed at Visborg, and he launched a rebellion in
Blekinge in April 1525, in the name of Christian II. Frederick I's general
Johan Rantzau defeated Norby, and he reached a settlement with Denmark, in which Norby exchanged Visborg for land in Blekinge. During the surrender of Visborg, Norby was
double crossed by Frederick I's advisor
Otte Krumpen and left for capture by Lübeck. However, he was promptly released as his men rejected leaving Visborg without him, and they then resettled in Blekinge as agreed. While in Blekinge, Norby continued his piracy against Lübeck and Sweden, and carried on supporting Christian II against Frederick I. His three enemies finally united to attack him in August 1526. Norby escaped to
Livonia, and travelled to
Vasili III of Russia in
Moscow. With the help of King
Ferdinand I of Bohemia, Norby travelled to
Mechelen where he was reunited with Christian II around November 1528. As Christian II's position was too weak to attempt a reconquest of Denmark, Norby travelled to join Charles II of Burgundy, now known as
Charles V, Holy Roman Emperor, in 1529. He wrote to Christian II of his partaking in the
Siege of Florence in February 1530, where he died shortly thereafter. ==References==
