Wars involving Korea

Korea's military history spans ancient polities, dynastic states, colonial occupation, a major internationalized civil war, and contemporary deployments. Korean states such as Gojoseon, Gaya Confederacy, Baekje, Goguryeo, Silla, Unified Silla, Balhae, Goryeo, and Joseon dynasty engaged rivals including Han dynasty, Tang dynasty, Liao dynasty, Jurchen people, Mongol Empire, Yuan dynasty, Ming dynasty, Qing dynasty, Japan, and modern powers. Major engagements include the Battle of Salsu, the Siege of Ansi, the Imjin War, the Later Jin invasion of Joseon, the First Sino-Japanese War, the Russo-Japanese War, the Japan–Korea Treaty of 1910 era conflicts, and the internationalized Korean War.

Ancient and Medieval Conflicts (Gojoseon to Goryeo)

Early wars feature Gojoseon's clash with the Wiman Joseon era and confrontation with the Han dynasty culminating in the Gojoseon–Han War. The Three Kingdoms period saw protracted warfare among Goguryeo, Baekje, and Silla and alliances with Tang dynasty forces leading to campaigns such as the Goguryeo–Tang War and sieges like the Siege of Ansi. Maritime and continental contests involved Wa (Japan), the Silla–Tang alliance, and the Balhae successor state's border skirmishes with Khitan people and Heishui Mohe. Goryeo confronted Khitan Liao in the Goryeo–Khitan War, repelled Mongol invasions of Korea which precipitated vassalage to the Yuan dynasty, and fought pirates and maritime raiders such as Wokou during the late medieval period.

Joseon dynasty conflicts included defensive campaigns against Jurchen people and diplomatic-military interaction with the Ming dynasty and later the Qing dynasty during the Later Jin invasion of Joseon and the Second Manchu invasion of Korea (1636). The peninsula suffered devastation in the Imjin War (Japanese invasions of Korea, 1592–1598) featuring the admiral Yi Sun-sin and the Battle of Myeongnyang. Internal rebellions and factional strife produced uprisings such as the Revolt of Gabo-era disturbances and the Hong Gyeong-nae Rebellion. Late Joseon era also experienced diplomatic-military crises in the First Sino-Japanese War and incidents tied to the Korean Empire's reformist movements and the Eulmi Incident.

Japanese intervention culminated in annexation under the Japan–Korea Treaty of 1910, provoking resistance from groups including the Korean Provisional Government and guerilla campaigns by figures like Kim Il-sung and Kim Koo operating in Manchuria and the Sakhalin region. Key episodes include the March 1st Movement, clashes with the Imperial Japanese Army, and exile-era diplomacy with the Soviet Union and Wang Jingwei regime-era Chinese factions. Independence forces engaged in battles such as those at Cheongsanri and coordinated with the Chinese Communist Party and Kuomintang at various times.

The Korean War began with the Invasion of South Korea by Korean People's Army forces and escalated into a multinational conflict involving the United Nations Command, the United States, People's Republic of China intervention via the People's Volunteer Army, and the Soviet Union's material support. Notable engagements include the Battle of Inchon, the Pusan Perimeter, the Battle of Chosin Reservoir, and the Battle of Heartbreak Ridge. Negotiations produced the Korean Armistice Agreement but no formal peace treaty, leaving the Demilitarized Zone and the Joint Security Area as enduring legacies.

After 1953, the peninsula experienced incidents including the Blue House Raid, the Axe Murder Incident, the EC-121 shootdown, the Korean Axe Murder Incident at Panmunjom and naval clashes such as the First Battle of Yeonpyeong and Second Battle of Yeonpyeong. The Korean People's Navy's provocations and Republic of Korea Navy responses, the DPRK submarine infiltration attempts, and the sinking of ROKS Cheonan exemplify ongoing low‑intensity conflict. Political crises tied to leaders like Park Chung-hee and Kim Il-sung influenced cross-border operations and clandestine actions including the Blue House Raid and assassination attempts such as the attempted assassination of Park Chung-hee.

Both Korean states and diaspora forces participated in international conflicts and peacekeeping: Republic of Korea Armed Forces deployed to the Vietnam War and to Operation Restore Hope in Somalia, and contributed to United Nations peacekeeping operations in East Timor, Iraq War stabilization efforts, and missions in Lebanon and South Sudan. The Korean People's Army undertaking of advisory roles with Vietnam People's Army and links to Soviet armed forces marked Cold War alignments. Contemporary collaborations include exercises with United States Forces Korea, multinational drills like Ulchi Freedom Guardian, and deployments under UN Command mandates.
