This gold crown was, most probably, crafted during the reign of Sultan Syarif Kasim I who, until 1889, was the ruler of the Siak kingdom. The last sovereign to own this now-famous crown was Sultan Syarif Kasim II, who ruled from 1915 to 1949. Following Indonesia's independence, Sultan Syarif Kasim II bequeathed the crown to the newly founded Republic of Indonesia, and later became an important part of the National Museum collection.
