Quick Summary

A tiara is a type of crown or ornamental headdress. Historically, it refers to the triregnum, a triple crown worn by the pope, symbolizing his authority. This papal tiara typically featured three gold bands, streamers, and sometimes a cross, and was made of precious metals. The practice of popes wearing the triregnum ended in the mid-20th century, with subsequent popes opting for a miter.12

In a broader sense, a tiara can also be a decorative headband or semicircle worn by women for formal occasions, often adorned with jewels or flowers. The term is also related to the word 'diadem,' which signifies a band or wreath worn on the head as a symbol of honor or victory.23
