[In Progress] Joseon

The Kingdom of Joseon, also known as Choson and Chosun, was a Korean kingdom founded by Yi Seonggye that lasted for approximately five centuries, from July 1392 to October 1897. It was officially renamed the Korean Empire in October 1897. It was founded following the aftermath of the overthrow of Goryeo in what is today the city of Kaesong. Early on, Korea was retitled and the capital was relocated to modern-day Seoul. The kingdom's northernmost borders were expanded to the natural boundaries at the Yalu and Tumen Rivers through the subjugation of the Jurchens. Joseon was the last dynasty of Korea and its longest-ruling Confucian dynasty. 

During its reign, Joseon encouraged the entrenchment of Chinese Confucian ideals and doctrines in Korean society. Neo-Confucianism was installed as the new dynasty's state ideology. Buddhism was accordingly discouraged and occasionally faced persecutions by the dynasty. Joseon consolidated its effective rule over the territory of current Korea and saw the height of classical Korean culture, trade, science, literature, and technology. However, the dynasty was severely weakened during the late 16th and early 17th centuries, when the Japanese invasions of Korea (1592-98) and the first and second Manchu invasions of 1636 nearly overran the Korean Peninsula, leading to an increasingly harsh isolationist policy for which the country became known as the "hermit kingdom". After the end of invasions from Manchuria, Joseon experienced a nearly 200-year period of peace.

However, whatever power the kingdom recovered during its isolation further waned as the 18th century came to a close, and faced with internal strife, power struggles, international pressure and rebellions at home, the Joseon dynasty declined rapidly in the late 19th century.

The Joseon period has left a substantial legacy to modern Korea; much of modern Korean culture, etiquette, norms, and societal attitudes towards current issues, and the modern Korean language and its dialects derive from the culture and traditions of Joseon.

History

Early Joseon period - Founding

By the late 14th century, the nearly 500-year-old Goryeo established in 918 was tottering, its foundations collapsing from years of war and de facto occupation from the disintegrating Mongol Empire. Following the emergence of the Ming dynasty, the royal court in Goryeo split into two conflicting factions: the group led by General Yi (supporting the Ming) and the camp led by General Choe (standing by the Yuan).

Goryeo claimed to be the successor of the ancient kingdom of Goguryeo (which was later renamed Goryeo); as such, restoring Manchuria as part of Korean territory was part of its foreign policy throughout its history. When a Ming messenger came to Goryeo in 1388, the 14th year of U of Goryeo, to demand that Goguryeo's former northern territory be handed over to Goryeo, General Choe seized the chance to argue for an attack on the Liaodong Peninsula. 

Yi was chosento lead the attack; however, he revolted and swept back to Gaegyeong and initiated a coup d'etat, overthrowing King U in favor of his son, Chang of Goryeo (1388). He later killed King U and his son after a failed restoration and forcibly placed a royal named Yi on the throne (he became Gongyang of Goryeo). In 1392, Yi eliminated Jeong Mong-ju, highly respected leader of a group loyal to Goryeo dynasty, and dethroned King Gongyang, exiling him to Wonju, and before he ascended the throne. The Goryeo Dynasty had come to an end after almost 500 years of rule.

In the beginning of his reign, Yi Seonggye, now ruler of Korea, intended to continue use of the name Goryeo for the country he ruled and simply change the royal line of descent to his own, thus maintaining the facade of continuing the 500-year-old Goryeo tradition. However, after numerous threats of mutiny from the drastically weakened but still influential Gwonmun nobles, who continued to swear allegiance to the remnants of the Goryeo and now the demoted Wang clan, and the consensus in the reformed court was that a new dynastic title was needed to signify the change. After much deliberation, king Taejo declared the name of the new dynasty to be "Joseon", after the ancient Korean state of Gojoseon (specifically Gija Joseon), which was allegedly founded in 2,333 B.C. He also moved the capital to Hanyang from Kaesong.

Strife of princes

When the new dynasty was promulgated and officially brought into existence, Taejo brought up the issue of which son would be his successor. Although Yi Bangwon, Taejo's fifth son by Queen Sineui, had contributed most to assisting his father's rise to power, the prime minister Jeong Do-Jeon and Nam Eun used their influence on King Taejo to name his eighth son (second son of Queen Sindeok) Grand Prince Uian (Yi Bangseok) as crown prince in 1392. This conflict arose largely because Jeong Dojeon, who shaped and laid down ideological, institutional, and legal foundations of the new dynasty more than anyone else, saw Joseon as a kingdom led by ministers appointed by the king while Yi Bangwon wanted to establish the absolute monarchy ruled directly by the king. With Taejo's support, Jeong Dojeon kept limiting the royal family's power by prohibiting political involvement of princes and attempting to abolish their private armies. Both sides were well aware of each other's great animosity and were getting ready to strike first.

After the sudden death of Queen Sindeok, while King Taejo was still in mourning for his second wife, Yi Bangwon struck first by raiding the palace and killed Jeong Dojeon and his supporters as well as Queen Sindeok's two sons (his half-brothers) including the crown prince in 1398. This incident became known as the First Strife of Princes.

Aghast at the fact that his sons were willing to kill each other for the crown, and psychologically exhausted from the death of his second wife, King Taejo abdicated and immediately crowned his second son Yi Banggwa as King Jeongjong. One of King Jeongjong's first acts as monarch was to revert the capital to Kaesong, where he is believed to have been considerably more comfortable, away from the toxic power strife. Yet Yi Bangwon retained real power and was soon in conflict with his disgruntled older brother. Yi Banggan, who also yearned for power. In 1400, the tensions between Yi Bangwon's faction and Yi Banggan's camp escalated into an all-out conflict that came to be know as the Second Strife of Princes. In the aftermath of the struggle, the defeated Yi Banggan was exiled to Dosan while his supporters were executed. Thoroughly intimidated, King Jeongjong immediately invested Yi Bangwon as heir presumptive and voluntarily abdicated. That same year, Yi Bangwon assumed the throne of Joseon at long last as King Taejong, third king of Joseon.
