Facts and Events
Christian IV (; 12 April 1577 – 28 February 1648), sometimes colloquially referred to as 'Christian Firtal' in Denmark and 'Christian Kvart' or 'Quart' in Norway, was a monarch of the House of Oldenburg who ruled as King of Denmark-Norway from 1588 to 1648. His reign of more than 59 years is the longest of all Danish monarchs.
Christian began his personal rule of Denmark in 1596 at the age of 19. He is frequently remembered as one of the most popular, ambitious, and proactive Danish kings, having initiated many reforms and projects. However, his personal obsession with witchcraft led to the public execution of some of his innocent subjects, leading to the greatest number of deaths in Denmark during the Burning Times. He renamed the Norwegian capital Oslo as Christiania after himself, a name used until 1925.
