A graduation cap, also known as a mortarboard, is a flat-topped academic cap worn by graduates at universities and colleges. It is typically made of black velvet or serge and has a tassel that hangs down from the center. Graduation caps are often decorated with the school’s colors or logo.
Graduation caps have been worn for centuries, and their design has changed little over time. The earliest known graduation caps were worn by students at the University of Oxford in the 14th century. These caps were made of black felt and had a square top. Over time, the design of graduation caps evolved, and the square top was replaced by a flat top. The tassel was also added at this time.
