An emperor (through Old French "empereor" from Latin imperator) is a monarch, usually the sovereign ruler of an empire or another type of imperial realm.
 Empress, the female equivalent, may indicate an emperor's wife ("empress consort"), mother ("empress dowager"), or a woman who rules in her own right ("empress regnant").
 Emperors are generally recognized to be of a higher honour and rank than kings.
 In Europe the title of Emperor has been used since the Middle Ages, considered in those times equal or almost equal in dignity to that of Pope, due to the latter's position as visible head of the Church and spiritual leader of the Catholic part of Western Europe.
 The Emperor of Japan is the only currently reigning monarch whose title is translated into English as "Emperor".

John (Danish and Norwegian: "Hans" ; Swedish: "Johan" ; né "Johannes") (2 February 1455 – 20 February 1513) was a Scandinavian monarch under the Kalmar Union.
 He was King of Denmark (1481–1513), Norway (1483–1513) and as John II (Swedish: "Johan II" ) Sweden (1497–1501).
 From 1482 to 1513, he was concurrently Duke of Schleswig and Holstein in joint rule with his brother Frederick.

A grand duchy is a country or territory whose official head of state or ruler is a monarch bearing the title of grand duke or grand duchess.
 Relatively rare until the abolition of the Holy Roman Empire in 1806, the term was often used in the official name of countries smaller than most continental kingdoms of modern Europe (e.g., Denmark, Spain, United Kingdom) yet larger than most of the sovereign duchies in the Holy Roman Empire, Italy or Scandinavia (e.g. Anhalt, Lorraine, Modena, Schleswig-Holstein).
 During the 19th century there were as many as 14 grand duchies in Europe at once (a few of which were first created as exclaves of the Napoleonic empire but later re-created, usually with different borders, under another dynasty).
 Some of these were sovereign and nominally independent (Baden, Hesse and by Rhine, Mecklenburg-Schwerin, Mecklenburg-Strelitz, Oldenburg, Saxe-Weimar and Tuscany), some sovereign but held in personal union with larger realms by a monarch whose grand-dukedom was borne as a subsidiary title (Finland, Luxembourg, Transylvania), some of which were client states of a more powerful realm (Cleves and Berg), and some whose territorial boundaries were nominal and the position purely titular (Frankfurt).

Question: In what year did the monarch whose flagship was called Griffen become king of Norway ?
