Gwanbok

''' (') is a Sino-Korean term derived from the terms (lit. 'guan and clothing'; ) and. The term  is a collective term which refers to historical official attire, which was bestowed by the government court, including Chinese courts of various dynasties. The  system was a court attire system in China which also formed part of the   system. This system was them spread to neighbouring countries and was adopted in Korea since ancient times in different periods through the ritual practice of bestowal of clothing. Acknowledgement through bestowed robes and crowns from the Emperor of China, who held hegemony over East Asia, would give support to Korean Kings and successors, as being the authentic rulers of their country as well as confirmed the political status of the Korean kingdom in the rest of the Sinosphere. The system in Korea was different for each kingdom and changed throughout different periods. For example, initially given by the Chinese court in ritual practice, successive were more often than not locally manufactured in Korea with different colours and adopted into hanbok. The, which was used as the uniform of court officials (including civil court officials), formed part of the system and was used like the suit is nowadays.

History and development
Before adopting foreign systems, Korea had its own system based on indigenous, mostly rooted in indigenous ranking systems and state religion like Mu-ism. They favoured luxurious clothes like purple clothing for the top ranks and had decorative golden metal crowns and pointy hats called adorned with metal accessories and feathers. Silla and the other three kingdoms of Korea each had a version of the Bone-rank system where each social rank were allowed only certain clothes and certain ranks in court.

The rulers and the upper class in Korea's history adopted different kinds of foreign-influenced clothing in each dynasty, mostly from China's Tang, Song, Yuan, and Ming dynasties, while the commoners were generally less influenced by these foreign trends and their indigenous aesthetic continued to be seen in their clothing. Despite wearing foreign-influenced clothing, the rulers and the upper class still wore clothing that were indigenous outside of court. Under the dominance of the Han dynasty, Goguryeo and the little states were bestowed attires and other miscellaneous items from the Han dynasty court. In the Goryeo dynasty, the system was largely influenced by the clothing system of other cultures, especially by the Han-Chinese ruled dynasties, the Mongolian Empire, the Khitan Liao dynasty (which adopted the ritual practice of bestowing  from the Later Jin in the 10th century and later imitated the practice ), and the Jurchen Jin dynasty. In Korea, whenever a new dynasty was established, the Korean ruler and his court would be bestowed official clothing from the Chinese emperor. This ritual of the Chinese Emperor bestowing official attire also included the official attire of the Korean Kings in the Goryeo and Joseon dynasties known as the Gonryongpo.

Goguryeo
After Gojoseon of Liaodong was defeated by the Han dynasty of China, four Chinese commanderies known as the Han-Sagoon were established in the region in 108 BCE. Proto-Koreanic entities were in constant conflict with these states until Goguryeo eventually ousted the Chinese from those regions by the early 4th century CE. One of them was the Daebang Commandery, established between 204 and 314 CE, and another was the Nakrang Commandery which continued to exist until the early fourth century CE and transmitted Han dynasty culture and lifestyle to the regions, including the Korean peninsula. Even after the ousting, Goguryeo court attire shows influences of the system.

A long type of po was introduced to Goguryeo and originated from the long which was worn by the Han Chinese in court.

Another form of robe was the mid-calf po, which originated from the Northern Chinese, and was used to fend against cold weather; this form of robe was adopted by the Goguryeo upper class for various ceremonies and rituals. This court po was eventually modified and became the with no vents. According to Samuel Lee: "'[Goguryeo] [m]urals 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 from the long coat worn by northern Chinese to fend off cold weather in ancient times. The long coats [of the 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 [of the court po] worn by the general populace came to be known as durumagi.'" The court po was used for ceremonies and rituals, as well as in the royal attire goguryeo called the. And, what is now currently known as the forms part of the indigenous hanbok attire as: The Han dynasty influences can also be observed in the tomb murals of Goguryeo which were primarily painted in two regions: Ji'an  and Pyeongyang, which are the second and third capitals of Goguryeo from the middle of the 4th to the middle of the 7th centuries respectively. The Goguryeo murals dating from this period in the region of Ji'an typically shows the characteristics of the people of Goguryeo in terms of morals and customs while those found in the regions of Pyeongyang would typically show the cultural influence of the Han dynasty, including figures dressed in attire, as the Han dynasty had governed this geographical region for approximately 400 years.

The Goguryeo mural paintings found near Pyeongyang, such as the Anak Tomb No. 3 of Goguryeo dated 357 AD located near Pyeongyang, shows also strong influences of the Eastern Han dynasty which appears to have continued lingering in the regions of Manchuria during the third and early fourth centuries CE. The subjects and characteristics found on the murals are derived from the murals found in the Eastern Han dynasty tombs of China. The tomb owner is depicted as an idealized official of the Eastern Han dynasty being seated in frontal position wearing a Chinese ; the closest prototype of this mural painting can be found in the mural from the Yuantaizi Tomb in Chaoyang country, Liaoning, dating from the 4th century CE. The painting of the wife of the tomb owner wears a multi-layered Chinese attire, known as the, and may indicate the Chinese clothing-style of the Six dynasties period. The Anak Tomb No. 3 also exerted strong influences on the subsequent development of iconography, structure, and tomb mural painting techniques found in the Goguryeo tombs.

Traces of influences from the Han dynasty continued to appear in the early 5th century Goguryeo tomb murals located in the Pyeongyang areas, such as those from the  where the ancient  worn by the owner of  tomb was red (or purple) in colour and had wide sleeves. It is also worn with a waist belt similarly to the native Korean --style.

"[Tomb Owner] This figure 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."

Illustrations of maids from the same tomb are also depicted wearing clothing attire which are similar to those worn from the North and South dynasties of China to the Tang dynasty the clothing attire of these maids are different from the one worn by the maids in the murals in Ji'an. Moreover, Goguryeo, influenced by the Chinese, also developed the ritual of bestowing attire to smaller entities, such as Silla, which in turn did so to other smaller entities.

Silla and Baekje
Southern parts of the Korean Peninsula had less influence from mainland political entities. The influence of Goguryeo can be seen in Silla court clothing, which included a similar decorative apron with triangles but under their (top) in a more indigenous fashion. Baekje had formed its own system with influences from Silla that in turn influenced the Japanese court attire of the Yayoi and Kofun periods.

Unified Silla
The official system of the Tang dynasty was brought into Korea in 647 AD by Kim Chunchu who travelled to the Tang to request clothing and belts. The  and the   are assumed to have been brought back by Kim Chunchu under the reign of Queen Jindeok of Silla and used as the uniform of court officials''. ''

Balhae
In Balhae, the official attire of civil and military officials were issued by the state. During King Mun's reign, Balhae started to integrate Tang dynasty elements, such as the and  into its official attire. The official court attire in Balhae varied in colour based on the rank of the official; the colours worn were purple, red, light red, and green.

Goryeo
In Goryeo, the was typically influenced by the Tang and Song dynasty. The , which was introduced during the United Silla period, continued to be worn as the outerwear of Goryeo officials and became part of the kingdom's official attire. However, the government officials continued to wear their daily-life clothing, such as a and  (trousers) under their  work clothing. Wearing everyday clothing under had already become a tradition since the Unified Silla period. The royalty and aristocrats of Goryeo also wore ' and ' that typically followed mainland Song dynasty official attire; this can be observed in Buddhist paintings of the Goryeo era. In 11th century, Goryeo was bestowed with the nine-stringed ' and ' and also received official attire from the Khitan Liao and Jurchen Jin dynasties as a sign that both were superior states to Goryeo. This ritual of bestowing attire to recognize a superior was broken during the Mongol Yuan dynasty. After Goryeo was subjugated by the Yuan dynasty of China, the Goryeo kings, royal court, and government had several titles and privileges downgraded to the point that they were no more the equals of the Yuan emperors. The Goryeo kings were themselves demoted from their traditional status of imperial ruler of a kingdom to the status of a lower-rank king of a vassal state;  as such they were forbidden from wearing the yellow  (dragon robes) as it was reserved for the Yuan emperors. At that time, they had to wear a purple  instead of a yellow one. Goryeo kings at that time sometimes wore Mongol attire instead; several Mongol clothing elements were adopted in the attire of Goryeo. Goryeo clothing-style customs also became popular at the end of the Yuan dynasty among Mongol rulers, aristocrats, queens and imperial concubines in the capital city under the influence of Empress Gi (a former Kongnyo and last empress of the Yuan dynasty, lit. "tribute women") when she was elevated as empress in 1365, a few years before the Yuan dynasty ended in 1368, and when she started to recruit many Goryeo women as court maids. The fashion trend was dubbed ' in ancient Chinese poetry from the Yuan dynasty and was described as being a ' ; without any visual illustration or unearthed artefacts of the , a suggested modern interpretation of the physical appearance of such garment was drawn in a 2005 study by senior researcher Choi based on the description provided by the same poem. According to Hyunhee Park: "Like the Mongolian style, it is possible that this Koryŏ style [Koryŏ yang] continued to influence some Chinese in the Ming period after the Ming dynasty replaced the Yuan dynasty, a topic to investigate further." The ritual bestowal of only resumed in late Goryeo. In an attempt to restore new cultural norms which they perceived as being non-contaminated by the Mongol cultural influences, King Gongming and King U of Goryeo tired to establish amicable diplomatic relationship with the Ming dynasty and voluntarily requested to be bestowed clothing from the Ming dynasty, which included their royal attire (e.g. the Dragon robe) and thus recognized the superiority of the Ming dynasty.

Court clothing
The system of Joseon continued the one used from the late Goryeo period and based itself on an early Ming dynasty court attire. However, since the establishment of the Joseon dynasty, the Joseon court developed stronger ties with Ming China and followed the Confucian dress system which became outlined in the 《》, a legal system which established Joseon as a vassal state and recognized China as the Suzerain. As such to reinforce this strict hierarchical system, the Joseon system had to two ranks below that of China as Joseon was a vassal state while China was the suzerain. But among other countries in the Sinosphere, Joseon was ranked second after Imperial China according to the concept of minor Sinocentrism, known as, with the Joseon dynasty equating Sinicization,  , with civilization.

Even after the fall of the Ming dynasty when the Chinese empire was no longer ruled by Han Chinese people, the rulers of Joseon did not regard the Manchu as the legitimate rulers of China; instead, they viewed the Joseon court as "the only true, legitimate heir to [the] Ming dynasty". This belief was reflected in the Joseon, which continued to show the Ming dynasty-based clothing design. It was also the pride of Joseon to preserve Confucian culture and visually manifest it through the traditional dress system of the Ming dynasty.

Moreover, the animosity caused by the Later Jin invasion fuelled this notion which continued due to the Qing invasion of Joseon. Joseon continued to use the Ming dynasty-based rather than receiving the Manchu-style, which they considered as being  and ironically barbaric. In the later half of the Joseon dynasty, as new could not be requested from the fallen Ming, it was instead manufactured in Korea which leads to its localization, such as the uniquely Korean U-shaped collar found in the, which can also be seen in later forms of.

Korean Empire
During the times of the Korean Empire, Emperor Gojong appropriated the highest formal, imperial dress of the Ming dynasty when he was enthroned as Emperor in 1897; Emperor Gojong wore the ' and had changed the original colour of his red ' to yellow, which was the same colour reserved to the Emperor of China. Only Emperor Gojong and Emperor Sunjong were able to wear the yellow . He also wore a decorated with the Twelve Ornaments along with a  with twelve beaded strings; a style of attire which he had appropriated from the  Chinese emperor when he declared himself emperor as he was only supposed to wear nine beaded strings when he was a feudal king.

He also included the  in his .

In the early Joseon, the Ming dynasty bestowed the, a plain red ceremonial robe along with , a with seven pheasants, to the Joseon queen which was then worn as a ceremonial attire.

In the late Joseon, the system of Joseon was developed and was modified such that pheasant heads would appear on the back of the  along and also added a rank badge to the.

The Korean differed from the  worn by the Chinese Emperor as the King of Joseon were feudal kings. As feudals kings, the Kings of Joseon were not allowed to use the twelve beaded strings instead they had to use nine beaded strings. Moreover, they were supposed to wear a robe in their which was decorated with nine out of the Twelve Ornaments and thus their this robe was referred. The nine ornaments on the were either painted or embroidered and they represented the virtue and authority of the King; the crown prince of Joseon on the other hand were only allowed seven out of the twelve ornaments.
