Decisive Tang China and Silla victory
The Baekje–Tang War was fought between Baekje and the allied forces of Tang and Silla between 660 and 663; it was in some respect a spillover of the, at the time, ongoing Goguryeo–Tang War. Silla primarily fought alone in the beginning, incurring significant losses in both manpower and territory. After numerous attacks and raids by the combined forces of Baekje and Goguryeo, King Muyeol sought help from Emperor Gaozong of Tang to defend his exhausted kingdom against the attacks, in return for potential territorial gains. Emperor Gaozong received and granted his request in early 660 and launched the invasion of Baekje. In 668, following a myriad of devastating skirmishes, the kingdoms of Goguryeo and Baekje succumbed to last two combined attacks in late 668 by numerically superior armies of the Tang Dynasty and Silla.
The war effectively marked the end of the Three Kingdoms of Korea period which had lasted since 57 BCE. The period conclusively ended with the concurrent Goguryeo–Tang War.
The Silla kingdom had formed a military alliance with the Tang empire under Emperor Gaozong's reign. When Goguryeo and Baekje attacked Silla from the north and west respectively, Queen Seondeok of Silla had sent an emissary to the Tang empire to desperately request military assistance. In 650, Emperor Gaozong received a poem, written by Queen Seondeok, from the princely emissary Kim Chunchu (who would later accede the Silla throne as King Muyeol). Baekje had allied with Yamato Wa in 653. Even though Baekje was allied with Goguryeo, the Han River valley separated the two states and was a hindrance in coming to each other's aid in time of war.King Muyeol assumed the Silla throne in 654. Between 655 and 659, the border of Silla was harassed by Baekje and Goguryeo; Silla therefore requested assistance from Tang.
