The tradition of graduation ceremony and graduation gown can be traced back to at least the 2nd century A.D./KLOC-0, when the first university was established in Europe. At that time, most students were clergy or determined to become clergy, so they did not advocate overdressing. At first, people thought that scholars and clergy should wear similar clothes. In the eyes of ordinary people, they all wear uniform clothes with simple colors.

Not only that, in fact, wearing this kind of clothes is also for practicality. When the university was just built, they didn't have a special teaching building for classes, so classes were held in a nearby church. Their simple robes and coats are designed to keep warm in the medieval church with air leakage all around, and the hood allows them to shelter from the wind and rain when attending classes outdoors.

At the Oxford Conference in 1222, Stephen Langton suggested that all priests should wear cappa clausa, a long shawl over robes. Soon, newly-built universities adopted this design, while ordinary priests gradually stopped wearing it and became the symbol of hoodies. By 132 1 year, the University of Coimbra required all students to wear solid color robes. During the Tudor dynasty, Oxford and Cambridge took the basic style as the standard of hoodies.

Later, for the sake of comfort, the heavy coat was gradually abandoned, but the robe remained. The color remains solid, basically black.

It was not until the late19th century that specific colors were used to represent different academic fields, and the standards of colors have been changed by different universities for hundreds of years.

This is the origin of the hat robe, so how did the doctor hat, or mortarboard (originally meant to support the gray board) come from?

One of the names of mortarboard is because the doctor's hat is like a board used by masons to hold mortar. The hat is square, a flat plate is placed on the hat without brim, and a common nail is tied in the middle. Some historians believe that the doctor's hat evolved from biretta (a hat worn by Roman Catholic priests, students and professors). The four-cornered cat hat may have evolved from the fur hat worn by ordinary people. It was first requested by the church at the religious conference in Bergamo in 13 1 and has been popular among priests ever since.

In the15th century, doctors' hats became part of many local standards. Unlike the current doctor's hat, there is nothing but spikes, and the early hats will have exquisite embroidery and ornaments.

Not only that, in some early universities, only people with "master's" and "doctor's" degrees have the right to wear this hat.
