Adalbert XX (28 November 1905 – 25 December 1921), sometimes known as Adalbert the Melancholic (Adalbert der Melancholiker) was the penultimate Emperor of Sunrosia, reigning from 28 November 1905 until his death on 25 December 1921. His sixteen years long reign, the second longest rule under Adalbertine Monarchy, saw the Great Collapse, the Airdale War and most of the Swetanian Revolution that led to the eventual end of the Sunrosian Monarchy a month after his death.
The third son of Adalbert XIX and Georgiana of Estmere, the then Prince Ludwig Adalbert wasn't the heir apparent until the death of his elder brother Prince Adalbert George in 1899. He assumed the throne six years later at the age of eleven, under a regency led by his mother Queen Georgiana that lasted until his majority and subsequent inauguration in 1912. Collaborating with the Chartist Association dominant in the Imperial Assembly, the regency oversaw a rollback of the autocratic reforms from Adalbert XIX's later reign, and in foreign policy favoured rapproachement with Estmere. Both policies were maintained by Adalbert XX's following the beginning of his personal rule, and he was generally considered to have been an Estmerophile.
