Swend-Ottó of Stairmark

Swend-Ottó (11 March 1923—19 March 2019) was the longest-reigning of any monarch of the Kingdom of Stairmark, ruling for a period of nearly 73 years. During the last three years of his rule, however, due to severe physical and moderate cognitive decline, Swend-Ottó's queen consort Ingá-Krístiná served as de facto regent, undertaking virtually all of the king's constitutional and ceremonial duties, including opening sessions of the Parliament of Stairmark, giving royal assent required to ratify legislation passed by Parliament, hosting foreign dignitaries and embarking on royal tours abroad, and much more. Upon the death of Swend-Ottó, his grandson Lárs-Erik succeeded to the throne.
