Phra Kiao (Thai: พระเกี้ยว [pʰráʔ kî:aw]), the Thai equivalent of the coronet, is a headgear traditionally worn by young princes and princesses. King Chulalongkorn adopted it as his personal emblem, as it coincided with the literal translation of his name. When King Chulalongkorn founded the Royal Pages School, he granted permission for the Phra Kiao to be used as the school's cap badge and symbol. The school later became Chulalongkorn University, which has since inherited and retained the symbol's use.
