The Coup d'état of December Twelfth or the 12·12 Military Insurrection (Korean: 12·12 군사 반란; Hanja: 十二十二軍事反亂) was a military mutiny which took place on December 12, 1979, in South Korea.

History

Republic of Korea Army Major General Chun Doo-hwan, commander of the Defence Security Command, acting without authorization from Acting President Choi Kyu-hah, ordered the arrest of General Jeong Seung-hwa, ROK Army Chief of Staff, on allegations of involvement in the assassination of former President Park Chung Hee. Minister of National Defense Roh Jae-hyun assisted in the arrest of Jeong. He would resign from office following the mutiny.

After Jeong's capture, the 29th Regiment of the 9th Division, along with the 1st Special Forces Brigade and 3rd Special Forces Brigade, invaded downtown Seoul to support the 30th and 33rd Capital Security Groups, which were loyal to Chun, resulting in a series of conflicts that broke out in the capital. Two of Jeong's allies, Major General Jang Tae-wan (Commander of Army Capital Security Command) and Major General Jeong Byeong-ju (Commander of Army Special Warfare Command), were also arrested by the rebelling 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 Headquarters were all occupied by the mutineers. Chun and his fellow graduates of the 11th class of the Korea Military Academy, such as Major General Roh Tae-woo, commanding general of 9th Infantry Division and Major General Jeong Ho-yong, were in charge of the Korean ground forces. Chun's mutiny and the subsequent consolidation of power was assisted by the powerful private club of military officials known as Hanahoe. The South Korean navy and air force did not participate in the mutiny and Chun subsequently co-opted them following the success of the mutiny. Chun became the de facto Commander-in-chief rather than Acting President Choi Kyu-hah.

The mutiny marked the beginning of the end of the Fourth Republic of Korea. The mutiny, the coup of the civilian government on 17 May 1980, alongside the Gwangju Uprising, was the primary justification for Chun's 1995 arrest by the Kim Young-sam administration.
