question: What was the age of Magnus Erikson when he mounted the Norwegian throne under the name of King Magnus VII?
article: Norway
candidates: Upon the death of Haakon V, King of Norway, in 1319, Magnus Erikson, at just three years old, inherited the throne as King Magnus VII of Norway. At the same time a movement to make Magnus King of Sweden proved successful. (At this time both the kings of Sweden and of Denmark were elected to the throne by their respective nobles.) Thus, with his election to the throne of Sweden, both Sweden and Norway were united under King Magnus VII. In 1349, the Black Death radically altered Norway, killing between 50% and 60% of its population and leaving it in a period of social and economic decline. The plague left Norway very poor. Although the death rate was comparable with the rest of Europe, economic recovery took much longer because of the small, scattered population. Before the plague, the population was only about 500,000 people. After the plague, many farms lay idle while the population slowly increased. The few surviving farms' tenants found their bargaining positions with their landlords greatly strengthened. King Magnus VII ruled Norway until 1350, when his son, Haakon, was placed on the throne as Haakon VI. In 1363, Haakon VI married Margaret, the daughter of King Valdemar IV of Denmark. Upon the death of Haakon VI, in 1379, his son, Olaf IV, was only 10 years old. Olaf had already been elected to the throne of Denmark on 3 May 1376. Thus, upon Olaf's accession to the throne of Norway, Denmark and Norway entered personal union. Olaf's mother and Haakon's widow, Queen Margaret, managed the foreign affairs of Denmark and Norway during the minority of Olaf IV. Margaret was working toward a union of Sweden with Denmark and Norway by having Olaf elected to the Swedish throne. She was on the verge of achieving this goal when Olaf IV suddenly died. However, Denmark made Margaret temporary ruler upon the death of Olaf. On 2 February 1388 Norway followed suit and crowned Margaret. Queen Margaret knew that her power would be more secure if she were able to find a king to rule in her place. She settled on Eric of Pomerania, grandson of her sister. Thus at an all-Scandinavian meeting held at Kalmar, Erik of Pomerania was crowned king of all three Scandinavian countries. Thus, royal politics resulted in personal unions between the Nordic countries, eventually bringing the thrones of Norway, Denmark, and Sweden under the control of Queen Margaret when the country entered into the Kalmar Union.
