Hanahoe Chun formed
Hanahoe as a secret military clique shortly after his promotion to
general officer. It was predominantly composed of his fellow graduates from the 11th class of the KMA, as well as other friends and supporters. Membership was predominantly restricted to officers from the
Gyeongsang Province with just a token membership reserved for a
Cholla Province officer. Hanahoe's existence within a highly regimented and rigid hierarchical organization of the army was only possible because it was under the patronage of then President Park.
Assassination of Park Chung Hee On 26 October 1979, Park was assassinated by
Kim Jae-kyu, Director of the
KCIA, while at a dinner party. Secretly, Kim had invited General
Jeong Seung-hwa, Army Chief of Staff, and Kim Jeong-seop, Vice-Deputy Director of the KCIA, to dinner in another room that night as well. Although Jeong Seung-hwa was neither present during nor involved in the shooting of Park, his presence at the scene later proved crucial to his downfall. In the chaos that followed, Kim Jae-kyu was not arrested for many hours, as details of the incident were initially unclear. After some confusion over the constitutional procedures for presidential succession, Prime Minister
Choi Kyu-ha finally ascended to the position of Acting President. Soon after, Jeong named Chun's Security Command to head up the investigation into the assassination. Chun immediately ordered his subordinates to draw up plans for the creation of an all-powerful "Joint Investigation Headquarters". On 27 October, Chun called for a meeting in his commander's office. Invited were four key individuals now responsible for all intelligence collection nationwide: KCIA Deputy Chief of Foreign Affairs, KCIA Deputy Chief of Domestic Affairs, Attorney General, and Chief of the National Police. On 5 November, a preliminary report was released by Chun, placing full responsibility of Park's assassination on Kim and his associates.
12 December mutiny In the following month Chun, along with
Roh Tae-woo, Yu Hak-seong, Heo Sam-su, and others from the Hanahoe, continued taking advantage of the fragile political situation to grow Hanahoe's strength, courting key commanders and subverting the nation's intelligence gathering organizations. General Jeong, his superior, is a moderate figure in the armed forces and gave hints on multiple occasions that he supported the
political liberalization process, as opposed to Chun, who favors keeping the Yushin Constitution intact. On 12 December 1979, amid a cabinet reshuffle, Chun ordered the arrest of Jeong on charges of conspiring with Kim Jae-kyu to assassinate Park. This order was made without authorization from President Choi. On the night of Jeong's capture, 29th Regiment,
9th Division, along with the 1st and 3rd Airborne Brigades, invaded downtown Seoul to support the 30th and 33rd Security Group loyal to Chun, which resulted in a series of conflicts that broke out in the capital.
Jang Tae-wan, commander of the Capital Garrison Command, and Jeong Byeong Ju, commander of the special forces, were also arrested by the rebel troops. Major Kim Oh-rang, aide-de-camp of Jeong Byeong-ju, was killed during the gunfight. By the next morning, the Ministry of Defense and Army HQ were all occupied, and Chun was in firm control of the military. For all intents and purposes, he was now the
de facto leader of the country. In early 1980, Chun was promoted to the rank of
lieutenant general, and he took up the position of acting director of the KCIA. On 14 April, Chun was officially installed as director of the KCIA.
Coup, martial law and military crackdown in Gwangju in Gwangju where victims' bodies were buried On 17 May 1980, Chun expanded martial law to the entire country, due to stated rumors of North Korean infiltration and presence of South Korean communist sympathizers in the country. The KCIA manipulated these rumors at the command of Chun. General
John A. Wickham (commander of the
US Armed Forces in Korea) reported that Chun's pessimistic assessment of the domestic situation and his emphasis on the North Korean threat only seemed to be a pretext for a move into the
Blue House (the Korean presidential residence). To enforce martial law, troops were dispatched to various parts of the nation. The expanded martial law closed universities, banned political activities, and further curtailed the press. Political opponents such as the recently freed
Kim Dae-jung was again arrested. The event of 17 May meant the beginning of another military dictatorship. Many civilians were growing unhappy with the military presence in their cities, and on 18 May, the citizens of
Gwangju organized protests into what became known as the
Gwangju Democratization Movement. Chun ordered it to be immediately suppressed, sending in shock troops armed with heavy weaponry such as armored tanks and helicopters to retake City Hall and ordered the troops to exercise full force. This led to a
bloody massacre over the next nine days, ultimately leading to the collapse of the protests and the deaths of at least 200 Gwangju activists. For this, he was called "The Butcher of Gwangju" by many people, especially among the students.
Path to the presidency In June 1980, Chun ordered the National Assembly to be dissolved. He subsequently created the (SCNSM), a
junta-like organization, and installed himself as head of command. On 17 July, he resigned his position as KCIA Director, and then held only the position of committee member. On 5 August, with full control of the military he effectively promoted himself to
four star General and on 22 August he was discharged from active duty to the Army reserves.
Samchung re-education camp Beginning in August 1980, citizens were subjected to organized violence under the name of
social cleansing, which aimed at the elimination of social ills, such as violence, smuggling, illegal drugs, and deceptions. They were arrested without proper warrants and given
ex parte rankings. Some 42,000 victims were enrolled in the
Samchung re-education camp for "purificatory education". More than 60,000 people were arrested in six months between August 1980 and January 1981, including many innocent citizens. They faced violence and hard labour in the re-education camp. ==Dictatorship (1980–1987)==
