Dae Jung-sang (?–698?), also known as Geolgeol Jungsang, was a key contributor to the founding of Balhae, and the father of Dae Jo-yeong, the founder of Balhae. Though much of the credit for the founding of Balhae went to his son, many historians still give credit to Dae Jung-sang as the main supporter and leader in the founding of Balhae.
The Old Book of Tang state that his eldest son, Dae Jo-yeong, was a former Goguryeo generalor chief of Sumo Mohe.
Most of the Goguryeo Aristocracy, including him, were taken to Yingzhou (Hanzi :營州), the homeland of the Khitan. Yingzhou became part of the Tang's General Protectorate to Pacify the East, and the Khitan were enraged.
In 696, the Khitan led a revolt that killed the cruel governor of the protectorate and gave Yingzhou back to the Khitan. Dae Jung-sang allied with the Baishan Mohe leader Geolsa Biu (Hangul: 걸사비우, Hanja: 乞四比羽 pinyin: Qǐsì bǐyǔ), and the two powers opposed the Tang influence in 698. The two leaders resisted the Tang's attack, but were forced to retreat. Both Geolsa Biu, and Dae Jung-sang died in battle, but Dae Jo-yeong led the remaining Goguryeo and Malgal soldiers and defeated the Tang army at the Battle of Cheonmun-ryeong and established the Balhae. The state was created by the leader of the Mohe people, who subjugated the neighboring tribes both by diplomatic and military force. The people of Goguryeo were subject to diplomatic power and voluntarily recognized him as their leader.
According to New Book of Tang, Wu Zetian created Dae as Duke of Jin (Zhen), Geolsa Biu as Duke of Heo (Xu), and pardon their crimes. Geolsa Biu refused the title and Wu sent general Li Kaigu to suppress the rebellions. Geolsa died in Battle of Tianmenling, Dae Jo-yeong led the others in victorious against Li. Dae Jung-sang died from sickness after the battle.
The most notable and famous of his children was his eldest, Dae Jo-yeong. Dae Jung-sang had another son, Dae Ya-bal (대야발), and probably also had other children besides Dae Jo-yeong because the Balhae Royal line consisted of two lineages, one from Dae Jo-yeong and the other from Dae Ya-bal.
Dae Jung-sang's forgotten establishing of a Successor-state of Goguryeo laid the foundations for the founding of an even more powerful kingdom, which was Balhae. Despite all of his hard work, most people remember his son Dae Joyeong as the founder of Balhae. Nevertheless, his descendants continued on the Balhae Royal line to the fifteenth generation.
Though Balhae fell, it left a further legacy. After most population of Balhae was moved to Khitan by Liao Dynasty, the last princes of Balhae quickly gathered the Balhae Aristocracy and retreated to Goryeo for sanctuary.Taejo of Goryeo gladly took them in and the Dae family continued on and still survives to this day as the Hyeop-gye Tae clan (협계 태씨).
Korea, or the Korean Peninsula, is a region in East Asia. Since 1945 it has been divided into the two parts which soon became the two sovereign states: North Korea and South Korea. Korea consists of the Korean Peninsula, Jeju Island, and several minor islands near the peninsula. It is bordered by China to the northwest and Russia to the northeast. It is separated from Japan to the east by the Korea Strait and the Sea of Japan.
The Lower Paleolithic era in the Korean Peninsula and Manchuria began roughly half a million years ago. The earliest known Korean pottery dates to around 8000 BC, and the Neolithic period began after 6000 BC, followed by the Bronze Age by 2000 BC, and the Iron Age around 700 BC.
Goguryeo, also called Goryeo, was a Korean kingdom located in the northern and central parts of the Korean Peninsula and the southern and central parts of Manchuria. At its peak of power, Goguryeo controlled most of the Korean peninsula, large parts of Manchuria and parts of eastern Mongolia and Inner Mongolia.
Balhae or Bohai (698–926) was a multi-ethnic kingdom in Manchuria, the Korean Peninsula and the Russian Far East which had been founded by Dae Joyeong after the fall of Goguryeo. The history of the founding of the state, its ethnic composition, the nationality of the ruling dynasty, the reading of their names, and its borders are the subject of a historiographical dispute between Korea and China.
The Changbai Mountains are a major mountain range in Northeast Asia that extends from the Northeast Chinese provinces of Heilongjiang, Jilin and Liaoning, across the border between China and North Korea, to the North Korean provinces of Ryanggang and Chagang. They are also referred to as the Šanggiyan Mountains in Manchu. Most peaks exceed 2,000 meters in height．
Dae Mu-ye, also known as King Mu, was the second king of the Balhae. He is noted for the military expansion of his domain.
Dae Joyeong, also known as King Go, established the state of Balhae, reigning from 699 to 719.
The Mohe, Malgal, or Mogher, maybe a mispronunciation of the word Mojie, were an East Asian Tungusic people who lived primarily in the modern geographical region of Northeast Asia. The two most powerful Mohe groups were known as the Heishui Mohe, located along the Amur River, and the Sumo Mohe, named after the Songhua River.
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. Throughout its history, Korea has boasted numerous exceptional leaders who gained outstanding victories against numerically superior enemies. Famed leaders credited with defending Korea against foreign invasions include: Eulji Mundeok of Goguryeo, who defeated Sui China during the Goguryeo–Sui War; Yeon Gaesomun of Goguryeo, who defeated Emperor Taizong of Tang China during the Goguryeo–Tang War; Gang Gam-chan of Goryeo, who defeated the Khitan Empire during the Goryeo-Khitan War; Choe Yeong and Yi Seong-gye of Goryeo, who defeated the Red Turbans, who later established Ming China, during the Red Turban Invasions; and Yi Sun-shin of Joseon, who defeated the Japanese at sea during the Imjin War. Other notable leaders include: Gwanggaeto the Great of Goguryeo, who created a great empire in Northeast Asia through conquest, and subjugated the other Korean kingdoms of Baekje, Silla and Gaya to bring about a brief unification of the Three Kingdoms of Korea; Geunchogo of Baekje, who captured Pyongyang and established overseas territories to control much of the Korean peninsula and dominate the seas; Munmu and Kim Yu-sin of Silla, who united the Three Kingdoms of Korea and defeated Tang China to gain complete control of the Korean peninsula; Dae Jo-yeong, who created Balhae from Goguryeo's ashes and reconquered Goguryeo lands lost during the Goguryeo-Tang War; Jang Bogo of Later Silla, who created a maritime empire and commanded a powerful fleet; Wang Geon, who united the Later Three Kingdoms of Korea and established Goryeo as the successor to Goguryeo; and Yun Gwan of Goryeo, who defeated the Jurchens and constructed nine fortresses in Manchuria.
The Battle of Tianmenling, or the Battle of Cheonmun-ryeong in Korean, was a battle fought between Dae Jo-yeong, later founder of Balhae, and Li Kaigu (李楷固), a Khitan commander of the Chinese Tang dynasty and Wu Zhou dynasty.
Later Balhae or Later Bohai was a controversial state in Manchuria. It emerged after Balhae (Bohai) was destroyed by the Liao dynasty. Later Balhae was the first of several successor states to Balhae after its fall to the Liao dynasty in 926.
The Northern and Southern States period is the period in Korean history when Unified Silla and Balhae coexisted in the south and north of the peninsula, respectively.
The Four Commanderies of Han were Chinese commanderies located in the north of the Korean Peninsula and part of the Liaodong Peninsula from around the end of the second century BC through the early 4th AD, for the longest lasting. The commanderies were set up to control the populace in the former Gojoseon area as far south as the Han River, with a core area at Lelang near present-day Pyongyang by Emperor Wu of the Han dynasty in early 2nd century BC after his conquest of Wiman Joseon. As such, these commanderies are seen as Chinese colonies by some scholars. Though disputed by North Korean scholars, Western sources generally describe the Lelang Commandery as existing within the Korean peninsula, and extend the rule of the four commanderies as far south as the Han River. However, South Korean scholars assumed its administrative areas to Pyongan and Hwanghae provinces.
The Goguryeo revival movements were various attempts to revive the Kingdom of Goguryeo after its defeat by the Silla-Tang alliance in 668. After 668, several different revival movements were initiated throughout the former territories of Goguryeo and some even in Tang territory. A new theory among Korean historians states that Gung-ye, the founder of Taebong, was a descendant of Anseung and the Go Dynasty. This theory has not been completely accepted yet, as more research is still in process.
Dae Jo-yeong is a South Korean television series aired from September 16, 2006 to December 23, 2007 on KBS1. It tells the life of Dae Jo-yeong, the founder of the kingdom of Balhae.
Hanpu or Hambo, later Wanyan Hanpu, was a leader of the Jurchen Wanyan clan in the early tenth century. According to the ancestral story of the Wanyan clan, Hanpu came from Goryeo when he was sixty years old, reformed Jurchen customary law, and then married a sixty-year-old local woman who bore him three children. His descendants eventually united Jurchen tribes into a federation and established the Jin dynasty in 1115. Hanpu was retrospectively given the temple name Shizu (始祖) and the posthumous name Emperor Yixian Jingyuan (懿憲景元皇帝) by the Jin dynasty.
Geolsa Biu was a 7th-century military leader of Baishan Mohe ancestry. Geolsa Biu took an active part in Balhae's effort for autonomy against the Tang Dynasty. Geolsa Biu died in the Battle of Tianmenling, in which Balhae achieved victory and declared autonomy.
Li Kaigu (李楷固), also known as Wu Kaigu (武楷固) from 700 to 705, formally the Duke of Yan (燕公), was a general during the reign of Wu Zetian. He was of Khitan ethnicity.
The tributary system of China, or Cefeng system was a network of loose international relations focused on China which facilitated trade and foreign relations by acknowledging China's predominant role in East Asia. It involved multiple relationships of trade, military force, diplomacy and ritual. The other nations had to send a tributary envoy to China on schedule, who would kowtow to the Chinese emperor as a form of tribute, and acknowledge his superiority and precedence. The other countries followed China's formal ritual in order to keep the peace with the more powerful neighbor and be eligible for diplomatic or military help under certain conditions. Political actors within the tributary system were largely autonomous and in almost all cases virtually independent.
The Balhae controversies are disputes between the three main parties conducting the study of this state Korea, China and Russia whose position is fully supported by Japanese historians, over the history of the Balhae/Bohai kingdom. Due to its origins as the successor state of Goguryeo, Korean scholars consider Balhae as part of the North–South States Period of Korean history, while Chinese scholars argue Bohai is a part of Chinese history. In traditional Russian historiography, this state is recognized as the first highly organized independent state formation of the Tungus-Manchurian peoples.
