The military history of Goguryeo involves wars with other Korean kingdoms, Chinese dynasties, nomadic states and tribes, and Wa Japan. Goguryeo was a highly militaristic state; [1] [2] it was a powerful empire and one of the great powers in East Asia, [3] [4] [5] [6] [ self-published source ] until it was defeated by a Silla–Tang alliance in 668 after prolonged exhaustion and internal strife caused by the death of Yeon Gaesomun. [7]
Goguryeo and Baekje were two of the Three Kingdoms of Korea; both claimed descent from the ancient Korean kingdom of Buyeo. Onjo, the founder of Baekje, was said to be the second son of Jumong, the founder of Goguryeo. [8] [9] [ self-published source ] Despite the common ancestry, the relationship between Goguryeo and Baekje was often contentious.
During the 4th century, Geunchogo expanded Baekje's territory to the north at the expense of Goguryeo. In 369, Gogukwon, the monarch of Goguryeo, attacked Baekje with 20,000 troops, but was defeated by Crown Prince Geungusu at the Battle of Chiyang. [10] In 371, Geungusu led 30,000 troops and attacked the fortress of Pyongyang, slaying Gogukwon in battle. [11] Baekje was a powerful maritime nation whose influence extended across the sea to Liaoxi and Shandong in China, taking advantage of the weakened state of Former Qin, and to Kyushu in the Japanese archipelago. [12]
Gogukyang, a son of Gogukwon, invaded Baekje in 386. [13] [14]
In 392, Gwanggaeto the Great led an attack on Baekje with 40,000 troops, capturing 10 walled cities. [15] In response, Asin, the monarch of Baekje, launched a counterattack on Goguryeo in 393 but was defeated. [15] Asin invaded Goguryeo once more in 394, but was defeated again. [15] After suffering multiple defeats against Goguryeo, Baekje's political stability began to crumble. [16] In 395, Baekje was defeated once more by Goguryeo and was pushed south to its capital of Wiryeseong on the Han River. [15] [17] In the following year, in 396, Gwanggaeto led an assault on Wiryeseong by land and sea, using the Han River, and triumphed over Baekje. [15] Gwanggaeto captured the Baekje capital and the defeated Asin submitted to him, [18] [19] surrendering a prince and 10 government ministers. [15] [20] Henceforth, Baekje lost its dominance in the central Korean peninsula and declined. [9]
In 400, Silla requested aid from Goguryeo in repelling an allied invasion by Baekje, Gaya, and Wa. Gwanggaeto dispatched 50,000 troops and annihilated the enemy coalition. [18]
In 433, Baekje and Silla formed an alliance (Hangul: 나제동맹, Hanja: 羅濟同盟) to balance the Goguryeo threat to the north. [21]
In 472, Gaero, the ruler of Baekje, requested a military alliance with Northern Wei against Goguryeo, but was unsuccessful. [21] [22] In 475, Jangsu, the son of Gwanggaeto, launched an invasion by land and sea against Baekje, and captured the capital of Wiryeseong and executed Gaero. [23] [24] Baekje had no choice but to move its capital to mountainous Ungjin (present-day Gongju), 80 miles to the south, which provided a natural protection for the devastated kingdom. [21] [25]
In 479, Baekje and Silla reaffirmed their alliance through marriage, [21] which was the primary reason why Goguryeo was unable to conquer the entire peninsula. [26] [ self-published source ]
In 551, a Baekje–Silla alliance attacked Goguryeo in order to capture the important Han River region from Goguryeo, planning to split it between them. In 553, Baekje gained the critical region after expending itself with a series of costly assaults on Goguryeo fortresses, but Silla troops, arriving on the pretense of offering assistance, attacked the exhausted Baekje troops and took possession of the entire Han River region, leading to a war between the two former allies in which the Baekje monarch was killed. [27] [28]
Baekje attacked Silla in 612, 624, and 627. [29] Goguryeo and Baekje formed an alliance (Hangul: 여제동맹, Hanja: 麗濟同盟) in 642 aimed toward territorial restoration against Silla. King Uija of Baekje attacked Silla and captured around 40 strongpoints in 642, [30] [ self-published source ] and 7 more fortresses in 645. [29] In 655, the Goguryeo–Baekje alliance captured 30 fortresses from Silla. [29]
In 245, Dongcheon ordered an attack on Silla, but the two kingdoms entered into friendly relations in 248. [31]
Nulji, the king of Silla, who had been a vassal of Jangsu, broke off relations with Goguryeo in 454. Jangsu invaded Silla in 468, expanding his domain into parts of Gangwon Province, and again in 489, capturing 7 walled cities and expanding his domain into parts of North Gyeongsang Province. [32]
Silla emerged as a major player in the Korean Peninsula after its betrayal of Baekje and conquest of the Han River region from Goguryeo in 553, [26] but Goguryeo and Baekje applied political, military, and economic pressure against Silla. In 643, under attack by the Goguryeo–Baekje alliance, the Silla court dispatched Kim Chunchu to the Tang dynasty to request military assistance, leading to Emperor Taizong's campaign against Goguryeo.
In 660, Goguryeo's ally, Baekje, fell to the Silla–Tang alliance; the victorious allies continued their assault on Goguryeo for the next eight years but could not defeat Yeon Gaesomun. However, Yeon Gaesomun died of a natural cause and civil war ensued among his three sons, leading the Silla–Tang alliance to launch a fresh invasion. In November 668, King Bojang surrendered to the Silla–Tang alliance and Goguryeo finally fell.
Goguryeo became a significant independent kingdom in the first century, and began expanding its power in the region. [1] [33] Taejodae conquered neighboring Okjeo and Dongye, and made repeated attacks against the Chinese commanderies and incursions into Liaodong, which would be continued by his successors. [1]
In 244, Guanqiu Jian, a general of Han's successor state Cao Wei, defeated Dongcheon and briefly occupied and sacked Goguryeo's capital. [34]
Wei invaded again in 259 but was defeated at Yangmaenggok; [35] according to the Samguk Sagi, Jungcheon assembled 5,000 elite cavalry and defeated the invading Wei troops, beheading 8,000 enemies. [36]
As Goguryeo extended its reach into the Liaodong Peninsula, the last Chinese commandery at Lelang was conquered and annexed by Micheon in 313, bringing the remaining northern part of the Korean peninsula into the fold. [37] This conquest resulted in the end of Chinese rule over territory in the northern Korean peninsula, which had spanned 400 years. [38] [39]
During the winter of 342, the Xianbei of Former Yan, ruled by the Murong clan, attacked and destroyed Goguryeo's capital, Hwando, capturing 50,000 Goguryeo men and women to use as slave labor in addition to taking the queen mother and queen prisoner and exhuming the body of Micheon, [40] and forced Gogukwon to flee for a while. The Xianbei also devastated Buyeo in 346, accelerating Buyeo migration to the Korean peninsula. [38]
In 385, Gogukyang, the son of Gogukwon, invaded and defeated Later Yan, the successor state of Former Yan. [13] [14]
In 400, the Xianbei state of Later Yan, founded by the Murong clan in present-day Liaoning, attacked Goguryeo. [41] Gwanggaeto the Great repulsed the enemy troops. [42] [43] In 402, Gwanggaeto retaliated and conquered the prominent fortress called 宿軍城 near the capital of Later Yan. [41] [44] In 405 and again in 406, Later Yan troops attacked Goguryeo fortresses in Liaodong (遼東城 in 405, and 木底城 in 406), but was defeated both times. [41] Gwanggaeto conquered all of Liaodong. [18] [45] By conquering Liaodong, Gwanggaeto recovered the ancient domain of Gojoseon; [18] [42] Goguryeo controlled Liaodong until the mid-late 7th century.
In 589, the Northern and Southern dynasties period ended and the Sui dynasty unified China after four centuries of fragmentation. [46] The Sui Empire reconquered Vietnam and defeated Champa, sacking its capital, [47] [ self-published source ] [48] and conquered important lands in northern China and Central Asia against Turks, Tibetans and proto-Mongolians. [49]
In 598, Goguryeo made a preemptive attack on Liaoxi, [50] leading Emperor Wen to launch a counterattack by land and sea that ended in disaster for Sui. [47] [51]
In 612, Emperor Yang mobilized a huge force said to number over a million men and invaded Goguryeo. [50] [51] [52] Unable to overcome the defenses of Yodong (Liaodong) Fortress, Emperor Yang ordered 305,000 troops to attack the Goguryeo capital of Pyongyang. [50] However, General Eulji Mundeok baited the Sui troops and annihilated them at the Battle of Salsu; [50] [51] [53] according to Chinese historical records: of the 305,000 Sui troops, a mere 2,700 returned. [54] Emperor Yang lifted his siege of the Korean fortress and withdrew his forces back to China. [50]
Emperor Yang was obsessed with defeating Goguryeo. [55] [56] He attacked Goguryeo again in 613 and 614, [57] [ self-published source ] [58] but failed against Goguryeo's defensive strategies, fierce resistance, and able leadership; [55] [56] furthermore, his campaign in 613 was cut short by internal discontent and floods back home. [57] [59] Emperor Yang's disastrous defeats in Korea greatly contributed to the collapse of the Sui dynasty. [51] [55] [56] [60]
Emperor Taizong ascended the Tang throne in 626, and led many successful military campaigns. In 630, Emperor Taizong defeated the Eastern Turkic Khaganate, an ally of Goguryeo, bringing much of Central Asia under Tang control; he then conquered the Tarim Basin, and defeated the Tibetan Empire in 640. [64] In 643, Queen Seondeok of Silla requested military aid against the Goguryeo–Baekje alliance. [60] [65] [ self-published source ] Tang forged an alliance with Silla, and began preparations for a major campaign against Goguryeo in 644. [66]
In 645, Emperor Taizong personally led a campaign against Goguryeo by land and sea with 113,000 Tang troops plus an unspecified number of tribal auxiliaries. [66] His noted army captured a number of Goguryeo border fortresses, including the potent Yodong (Liaodong) Fortress, which had repulsed Emperor Yang in 612 and 613. [67] Arriving outside Ansi Fortress on July 18, Emperor Taizong prepared to meet an approaching relief army, said to number 150,000 men, in battle. Emperor Taizong ordered Li Shiji to bait the Koreans with 15,000 troops, while Zhangsun Wuji's concealed troops would ambush them from behind. [67] On the following day, the two sides clashed and Emperor Taizong inflicted a crushing defeat on the confused Koreans, inflicting 20,000 casualties and capturing 36,800 prisoners. [67] Emperor Taizong then laid siege to Ansi Fortress; his troops attacked the Korean fortress as many as six or seven times per day, but were repelled each time by the defenders. [68] Unable to breach the adamant fortress despite months of siege, Tang eventually staked everything on the construction of a huge mound, designed to tower over the walls of the fortress; however, the defenders captured and successfully held the mound despite three days of frantic assaults by Tang troops. [69] Furthermore, exacerbated by worsened conditions for the Tang army due to cold weather (and winter approaching) and diminishing provisions, Emperor Taizong was compelled to order a withdrawal from Goguryeo on October 13, [69] but left behind an extravagant gift for Yang Manchun, the commander of Ansi Fortress. [70]
Emperor Taizong attacked Goguryeo again in 647 and 648, but was unsuccessful. [71] [72] [73] [74]
Defeating Goguryeo had been an obsession with Emperor Taizong, [75] [ self-published source ] and after his death in 649, his son Emperor Gaozong continued his ambition. Upon the suggestion of Kim Chunchu, the Silla–Tang alliance first conquered Baekje in 660 to break up the Goguryeo–Baekje alliance, and then turned its full attention to Goguryeo. [76] However, Emperor Gaozong, too, was unable to defeat Goguryeo led by Yeon Gaesomun; [76] [77] one of Yeon Gaesomun's most notable victories came in 662 at the Battle of Sasu (蛇水), where he annihilated the Tang forces and killed the invading general Pang Xiaotai (龐孝泰) and all 13 of his sons. [78] [79] Hence, while Yeon Gaesomun was alive, Tang could not defeat Goguryeo. [80]
In 666 (though dates vary from 664–666), Yeon Gaesomun died of a natural cause and a civil war ensued among his three sons. His eldest son and immediate successor, Yeon Namsaeng, defected to Tang and provided the secrets and weaknesses of Goguryeo to Emperor Gaozong, and played a critical role in the next invasion and downfall of Goguryeo. [81] Yeon Gaesomun's second son, Yeon Namgeon, resisted in the face of death, as opposed to his brother's treachery, and fought until the very end. Meanwhile, Yeon Gaesomun's younger brother, Yeon Jeongto, defected to the Silla side. [82]
The Tang–Silla alliance mounted a fresh invasion of Goguryeo in 667, aided by the defector Yeon Namsaeng, [82] and in 668, finally vanquished the divided kingdom, which had been plagued by violent dissension, numerous defections, and widespread demoralization following the death of Yeon Gaesomun. [7]
Silla thus unified most of the Korean peninsula in 668, but the kingdom's reliance on Tang China had its price. Tang China attempted to impose its rule over the entire Korean peninsula, but Silla, aided by Goguryeo and Baekje refugees, forcibly resisted and expelled Tang. [83] [ self-published source ] However, Silla's unification of the Three Kingdoms of Korea was short-lived because the former Goguryeo general Dae Joyeong led remnants of Goguryeo, united with the Mohe people, and established Balhae, a successor of Goguryeo. [84] Balhae eventually reconquered and retained much of Goguryeo's former territory.
The Tang dynasty Goguryeo general Gao Juren ordered a mass slaughter of Sogdian Caucasians from West and Central Asia, identifying them through their big noses and lances were used to impale Caucasian children when he stormed Beijing (Jicheng (Beijing)) from An Lushan when he defeated An Lushan's rebels. [85] [86]
Balhae became a powerful empire like its predecessor, but its eventual end came at the hands of the Khitan Empire in 926. Balhae's end was a decisive event in Northeast Asian history for it was the last Korean kingdom to hold territory in Manchuria. Goguryeo was revived once more in 918 by successor state Goryeo, [87] [88] [89] [90] founded by Wang Geon, a descendant of Goguryeo nobility. [91] [ self-published source ] [92] In 937, much of the ruling class and the last crown prince of collapsed Balhae fled to Goryeo, where he was warmly welcomed and included into the ruling family by Wang Geon, thus unifying the two successor nations of Goguryeo. [93]
In 395, Gwanggaeto the Great invaded the Khitan Baili clan to the west on the Liao River, [94] destroying 3 tribes and 600 to 700 camps. [95]
In 398, Gwanggaeto conquered the Sushen people to the northeast, [18] who were Tungusic ancestors of the Jurchens and Manchus. [96] [ self-published source ]
In 479, Jangsu invaded the Khitans, and then attacked the Didouyu with his Rouran allies. [97]
In 404, Gwanggaeto defeated an attack by the Wa from the Japanese archipelago on the southern border of what was once the Daifang commandery, inflicting enormous casualties on the enemy. [41] [98] [99]
Goguryeo also later known as Goryeo, was a Korean kingdom located in the northern and central parts of the Korean Peninsula and the southern and central parts of modern day Northeast China. At its peak of power, Goguryeo controlled most of the Korean Peninsula, large parts of Manchuria and parts of eastern Mongolia and Inner Mongolia as well as Russia.
Baekje or Paekche was a Korean kingdom located in southwestern Korea from 18 BC to 660 AD. It was one of the Three Kingdoms of Korea, together with Goguryeo and Silla. While the three kingdoms were in separate existence, Baekje had the highest population of approximately 3,800,000 people, which was similar to that of Goguryeo and much larger than that of Silla.
The Three Kingdoms of Korea or Samhan competed for hegemony over the Korean Peninsula during the ancient period of Korean history. During the Three Kingdoms period, many states and statelets consolidated until, after Buyeo was annexed in 494 and Gaya was annexed in 562, only three remained on the Korean Peninsula: Goguryeo, Baekje and Silla. The "Korean Three Kingdoms" contributed to what would become Korea; and the Goguryeo, Baekje and Silla peoples became the Korean people.
Gwanggaeto the Great was the nineteenth monarch of Goguryeo. His full posthumous name means "Entombed in Gukgangsang, Broad Expander of Domain, Peacemaker, Supreme King", sometimes abbreviated to Hotaewang. His era name is Yeongnak and he is occasionally recorded as Yeongnak Taewang. Gwanggaeto's imperial reign title meant that Goguryeo was on equal standing as an empire with the imperial dynasties in China.
Yeon Gaesomun (594–666) was a powerful military dictator in the waning days of the Goguryeo kingdom, which was one of the Three Kingdoms of ancient Korea. He is remembered for his successful resistance against Tang China under Emperor Taizong and his son Emperor Gaozong.
Uija of Baekje was the 31st and final ruler of Baekje, one of the Three Kingdoms of Korea. His reign ended when Baekje was conquered by an alliance of the rival Korean kingdom Silla and China's Tang dynasty.
Bojang of Goguryeo was the 28th and last monarch of Goguryeo the northernmost of the Three Kingdoms of Korea. He was placed on the throne by the military leader Yeon Gaesomun. His reign ended when Goguryeo fell to the allied forces of the southern Korean kingdom of Silla and the Chinese Tang dynasty.
Jangsu of Goguryeo was the 20th monarch of Goguryeo, the northernmost of the Three Kingdoms of Korea. He was born in 394 as the eldest son of Gwanggaeto. He became the crown prince in 408, and upon his father's death in 413, became the ruler at the age of 19.
Korea's military history spans thousands of years, beginning with the ancient nation of Gojoseon and continuing into the present day with the countries of North Korea and South Korea, and is notable for its many successful triumphs over invaders.
Jinpyeong was the 26th king of the Silla dynasty, one of the Three Kingdoms of Korea. King Jinpyeong followed in the footsteps of his predecessor, King Jinji, by reorganizing the central ruling system of Silla. Upon the onset of a multitude of conflicts between Baekje and Goguryeo, he sent emissaries to improve relations and strengthen ties between Silla and the Chinese dynasties Sui and Tang. He is also known for his promotion of Buddhism as a spiritual guide for the kingdom and encouraging Buddhist teachings.
Munja of Goguryeo or Munjamyeong of Goguryeo was the 21st monarch of Goguryeo, the northernmost of the Three Kingdoms of Korea. He was the grandson of Taewang Jangsu (413–491). Though Munja's father Gochudaega Joda had been named Crown Prince by Taewang Jangsu, Joda died before assuming the throne. He is considered as a ruler of Goguryeo at its zenith from Gwanggaeto the Great.
Gungnae or Guonei was the capital of the ancient Korean kingdom of Goguryeo, which was located in Manchuria and the Korean Peninsula. The perimeter of its outer fortress measures 2,686m. It is located in present day Ji'an city, Jilin province, northeast China. Because of its historical importance and exceptional architecture, Gungnae was designated as a UNESCO World Heritage Site in 2004. It is part of the Capital Cities and Tombs of the Ancient Koguryo Kingdom World Heritage Site, together with nearby Hwando Mountain City and the Onyeosan City, in modern northeast China.
Xue Rengui, formal name Xue Li (薛礼) but went by the courtesy name of Rengui, was a Chinese military general during the early Tang dynasty. He is one of the most well-known military generals of his time due to his humble background, outstanding command abilities, strength and valour in battle. During his career, he participated in successful campaigns against remnants of Western Tujue and against Goguryeo, with only one major flaw on his record which was a campaign against the Tibetan Empire in 670, where another general in his army refused to listen to Xue's advice and charged ahead and caused a portion of the army to be lost.
The Goguryeo–Tang War occurred from 645 to 668 and was fought between Goguryeo and the Tang dynasty. During the course of the war, the two sides allied with various other states. Goguryeo successfully repulsed the invading Tang armies during the first Tang invasions of 645–648. After conquering Baekje in 660, Tang and Silla armies invaded Goguryeo from the north and south in 661, but were forced to withdraw in 662. In 666, Yeon Gaesomun died and Goguryeo became plagued by violent dissension, numerous defections, and widespread demoralization. The Tang–Silla alliance mounted a fresh invasion in the following year, aided by the defector Yeon Namsaeng. In late 668, exhausted from numerous military attacks and suffering from internal political chaos, Goguryeo and the remnants of Baekje army succumbed to the numerically superior armies of the Tang dynasty and Silla.
The first conflict of the Goguryeo–Tang War started when Emperor Taizong of the Tang dynasty led a military campaign against Goguryeo in 645 to protect Silla and punish Generalissimo Yeon Gaesomun for the killing of King Yeongnyu. The Tang forces were commanded by Emperor Taizong himself, and generals Li Shiji, Li Daozong, and Zhangsun Wuji.
The Silla–Tang War (670–676) occurred between the Silla kingdom of Korea and the Tang dynasty of China. It began in the geopolitical context immediately following the conquest of Goguryeo and Baekje by the joint forces of Silla and Tang. The conflict ended with a truce between Tang and Silla due to the internal political situation in both states, with the dividing territorial line at the Taedong River basin.
The history of Sino-Korean relations dates back to prehistoric times.
The siege of Ansi took place between Goguryeo and Tang forces in Ansi, a fortress in the Liaodong Peninsula, and the culmination of the First campaign in the Goguryeo–Tang War. The confrontation lasted for about three months from 20 June 645 to 18 September 645.
The Battle of Mount Jupil, also known as Battle of Jupil-san and Battle of Mount Zhubi was a battle between Tang Chinese and Goguryeo Korean forces that took place in Mount Jupil at the south of the fortress city of Ansi. It took place on July 11, 645 AD. The small but elite Tang army wiped out the Goguryeo relief force trying to come to bolster the defenses of Ansi, achieving a major victory.
The Battle of the Sasu River, also known as Battle of Sasu was a battle between Tang Chinese and Goguryeo Korean forces that took place in 662 AD. An Chinese army, mostly consisting of soldiers from Lingnan, were led by general Pang Xiaotai while the Goguryeo army was led by the generalissimo Yeon Gaesomun. The Goguryeo army won the battle and the Tang army was crushed.
Wei. In 242, under King Tongch'ŏn, they attacked a Chinese fortress near the mouth of the Yalu in an attempt to cut the land route across Liao, in return for which the Wei invaded them in 244 and sacked Hwando.
十二年冬十二月王畋于杜訥之谷魏將尉遲楷名犯長陵諱將兵來伐王簡精騎五千戰於梁貊之谷敗之斬首八千餘級
Soon after, the Wei fell to the Jin and Koguryŏ grew stronger, until in 313 they finally succeeded in occupying Lelang and bringing to an end the 400 years of China's presence in the peninsula, a period sufficient to ensure that for the next 1,500 it would remain firmly within the sphere of its culture. After the fall of the Jin in 316, the proto-Mongol Xianbei occupied the North of China, of which the Murong clan took the Shandong area, moved up to the Liao, and in 341 sacked and burned the Koguryŏ capital at Hwando. They took away some thousands of prisoners to provide cheap labour to build more walls of their own, and in 346 went on to wreak even greater destruction on Puyŏ, hastening what seems to have been a continuing migration of its people into the north-eastern area of the peninsula, but Koguryŏ, though temporarily weakened, would soon rebuild its walls and continue to expand.
Loath to let slip such an opportunity, T'ang mounted a fresh invasion under Li Chi in 667 and Silla launched a coordinated offensive. This time the T'ang army received every possible assistance from the defector Namsaeng, and although Koguryŏ continued to hold out for another year, the end finally came in 668.
When Parhae perished at the hands of the Khitan around this same time, much of its ruling class, who were of Koguryŏ descent, fled to Koryŏ. Wang Kŏn warmly welcomed them and generously gave them land. Along with bestowing the name Wang Kye ("Successor of the Royal Wang") on the Parhae crown prince, Tae Kwang-hyŏn, Wang Kŏn entered his name in the royal household register, thus clearly conveying the idea that they belonged to the same lineage, and also had rituals performed in honor of his progenitor. Thus Koryŏ achieved a true national unification that embraced not only the Later Three Kingdoms but even survivors of Koguryŏ lineage from the Parhae kingdom.
He also conquered Sushen tribes in the northeast, Tungusic ancestors of the Jurcid and Manchus who later ruled Chinese "barbarian conquest dynasties" during the twelfth and seventeenth centuries.
