Gustav I of Sweden.

Gustav I, also known as Gustav Vasa (12 May 1496 – 29 September 1560), was King of Sweden from 1523 until his death, previously self-recognised Protector of the Realm (Rikshövitsman) from 1521, during the ongoing Swedish War of Liberation against King Christian II of Denmark, Norway and Sweden. Gustav's election as King on 6 June 1523 and his triumphant entry into Stockholm eleven days later meant the end of Medieval Sweden's elective monarchy as well as the Kalmar Union. This created a hereditary monarchy under the House of Vasa and its successors, including the current House of Bernadotte. (Photo by: Universal History Archive/UIG via Getty images)
