Kort Rogge's mother Dorotea, née Horn, was a burgher in Stockholm and is mentioned as a house-owner in 1467, more than ten years after her husband's death.
Kort Rogge would later refer to himself as a "citizen of Stockholm" and appears to have maintained close ties to his native city throughout his life.
In 1469, he was chosen by King Charles VIII of Sweden to represent him, together with the chancellor Clas Rytting, at peace negotiations with Denmark in Lübeck.
He initiated a number of reforms, including the introduction of printed books in the Diocese and several refurbishments and construction works at Strängnäs Cathedral.
[3] Rogge brought with him a book collection from Italy, which was focused on literature, law and history, and from which theological writings were conspicuously absent.
