The styling of the outer part of the crowns suggests a Korean connection with the Scytho-Iranians (Saka) through contact with people of the Eurasian steppe. The crowns are a uniquely Korean product and show no Chinese influence. The Silla crown is also notably distinct from the crown of Baekje, the crown of Gaya, and the crown of Goguryeo kingdoms. The tree motif of the crown is commonly believed to represent the idea of the world tree which was an important tenet of Siberian and Iranian shamanism.
