Silla Unification of the Three Kingdoms

Timeline

1. 668–670Ungjin Protectorate · South KoreaAfter Goguryeo's fall, the Tang sought long-term control of the peninsula, establishing protectorates such as Ungjin and Andong. Silla believed Tang had violated their alliance by monopolizing the fruits of war; King Munmu began secretly preparing for war, and the Tang–Silla alliance broke down.
2. 671–675Battlefields across the peninsula · Korean PeninsulaSilla launched a full counteroffensive; King Munmu personally led the main army, while famous generals Kim Yushin and Kim Ingyeong attacked along separate routes, successively capturing Tang positions. Tang general Liu Renyuan and others were forced to retreat, and Silla recovered most of the former Baekje and Goguryeo territories.
3. 676South of the Taedong River · Korean PeninsulaBy 676, Silla essentially controlled all territory south of the Taedong River, ending the three-kingdoms stalemate and beginning the era of Unified Silla. Tang and Silla thereafter maintained tributary relations, and the southern peninsula achieved political unification.
