History
The origin of traces back to at least the Three Kingdoms of Korea, where it originated from a long coat worn by the northern asian to fend off cold weather in ancient times.

Tomb murals from Goguryeo were primarily painted in two regions, Ji'an and Pyeongyang, which are the second and third capitals of the Goguryeo from the middle of the 4th to the middle of the 7th centuries respectively.

According to Samuel Lee, the origins of the can be traced back to the Goguryeo period:

"'[Goguryeo] Murals also show that both men and women wore chima. The type worn by both for formal occasions was sang and that worn only by women was goon, which had long and wide dimensions. The origin of durumagi, the long outer coat worn over a jeogori, goes back to the Goguryeo period. The durumagi emanates form the long coat worn by northern Chinese to fend off cold weather in ancient times. The long coat [worn by northern Chinese] reached mid-calf and had bindings similar to those used for jeogori. Later, this [long coat] was adopted by the Goguryeo upper class in various forms for ceremonies and rituals, and the modified form worn by the general populace came to be known as durumagi."

However, what is now known as the is part of the indigenous attire of the Korean people:

Based on the Goguryeo mural paintings found near Pyeongyang, such as the early 5th century murals from, the ancient  worn by the owner of  tomb was red (or purple) in colour:

"[The tomb of the owner of Gamsinchong Tomb] is sitting on a flat bench under a red curtain, in a purple durumagi (a traditional Korean men’s overcoat) with both hands held inside the wide sleeves on his chest. He wears a dark silk hat that shows his high societal position."

The murals show a mixture of elements from before and after the fifth century; the wide-sleeves attire also reflect the characteristics of tomb murals which are found near the Pyeongyang area. The ancient was also worn with a waist belt and had wide sleeves.

Goryeo
During the Goryeo period, Mongolian influences caused the to change in appearance. Not only was the waist belt changed into a, the traditional 's short length and wide sleeves were lengthened and narrowed to the style of the Mongolian coat, , of which the name is said to be derived.

Joseon period
During the Joseon dynasty, the was less worn as an overcoat but more of a housecoat for the noble class, whereas it was worn outdoors by the commoners. In 1884, King Gojong promulgated the unification of clothing for all social classes through reform laws. However, this law was met with much resistance and it was only until ten years later, after the Gabo Reform of 1894, that the became common as formal attire.
