dolmen

A dolmen, also known as a portal tomb, portal grave, or quoit, is a type of single-chamber megalithic tomb, usually consisting of three or more upright stones supporting a large flat horizontal capstone (table), although there are also more complex variants. Most date from the early Neolithic period (4000 to 3000 BC). Dolmens were usually covered with earth or smaller stones to form a barrow, though in many cases that covering has weathered away, leaving only the stone "skeleton" of the burial mound intact.

It remains unclear when, why, and by whom the earliest dolmens were made. The oldest known dolmens are in Western Europe, where they were set in place around 7000 years ago, at the same time as the ancient civilisations of Egypt, India, and the Middle East. Archaeologists still do not know who erected these dolmens, which makes it difficult to know why they did it. The most widely accepted theory is that all dolmens are tombs or burial chambers. Human remains, sometimes accompanied by artifacts, have been found in or close to them, which could be scientifically dated. There is however no firm evidence that even this theory is correct. It has been impossible to prove that these archaeological remains date from the time when the stones were set in place.

Korea

The largest concentration of dolmen in the world is found on the Korean peninsula. With an estimated 35,000 dolmen, Korea alone accounts for nearly 40% of the world’s total.
The largest distribution of these is on the west coast area of South Korea.
Three specific UNESCO World Heritage sites at Gochang, Hwasun and Ganghwa by themselves account for over 1,000 dolmen.
The Korean word for dolmen is goindol (hangul:고인돌). Serious studies of the Korean megalithic monuments were not undertaken until relatively recently, well after much research had already been conducted on dolmen in other regions of the world. After 1945, new research is being conducted by Korean scholars.

Korean dolmen exhibit a morphology distinct from the Atlantic European dolmen.
In 1981 a curator of Seoul's National Museum of Korea, Gon-Gil Ji, classified Korean dolmen into two general types: northern and southern. The boundary between them falls at the Bukhan River although examples of both types are found on either side. Northern style dolmens stand above ground with a four sided chamber and a megalithic roof (also referred to as "table type"), while southern style dolmens are normally built into the ground and contain a stone chest or pit covered by a rock slab.

Korean dolmen can also be divided into 3 main types: the table type, the go-table type and the unsupported capstone type. The dolmen in Ganghwa is a northern-type, table-shaped dolmen and is the biggest stone of this kind in South Korea, measuring 2.6 by 7.1 by 5.5 metres. There are many sub-types and different styles. Southern type dolmen are associated with burials but the reason for building northern style dolmen is uncertain.

Due to the vast numbers and great variation in styles, no absolute chronology of Korean dolmen has yet been established. It is generally accepted that the Korean megalithic culture emerged from the late Neolithic age, during which agriculture developed on the peninsula, and flourished throughout the Bronze Age. Thus, it is estimated that the Korean dolmen were built in the first millennium BC.

How and why Korea has produced so many dolmen are still poorly understood. There is no current conclusive theory on the origin of Korea's megalithic culture, and so it is difficult to determine the true cultural character of Korean dolmen. A few northern style dolmens are found in Manchuria and the Shandong Peninsula. Off the peninsula, similar specimens can be found in smaller numbers, but they are often considerably larger than the Korean dolmen.
 It is a mystery as to factors caused this culture to flourish so extensively only on the Korean peninsula and its vicinity in Northeast Asia.

Gojoseon

Gojoseon  is said to have been an ancient Korean kingdom. The addition of Go (고, 古), meaning "ancient," distinguishes it from the Joseon Dynasty; Joseon, is also romanized as Chosŏn.
The first mentioning of this name however does not appear until the Samguk Yusa and other medieval-era records, where Gojoseon is said to have been founded in 2333 BC by Dangun in the legend, who is said to be a Posterity of Heaven.

Archaeological evidence of a Gojoseon-era civilization is found in the transition from the Jeulmun pottery to the Mumun pottery around 1500 BC, when groups of semi-sedentary small-scale agriculturalists occupied most of the Korean Peninsula. Local bronze production began around the 8th century BC. Based on Chinese records, some modern historians believe it developed from a loose federation into a kingdom between the 8th and 4th centuries BC, although this theory is contested.

The territory of Gojoseon was invaded by the Han Dynasty of China during the Gojoseon–Han War in 108 BC, which is said to have led to the collapse of the kingdom into many small states, until the Proto–Three Kingdoms emerged and marked an own period in Korean history.

The people of the Gojoseon-territory are referred to in Chinese records as Dongyi "eastern barbarians." Their language was probably a predecessor of the equally prehistoric Buyeo languages, and perhaps a form of Proto-Korean.

Dangun Wanggeom

Dangun Wanggeom, or Tangun, was the legendary founder of Gojoseon, the first Korean kingdom, around present-day Liaoning, Manchuria, and the Korean Peninsula. He is said to be the "grandson of heaven", and to have founded the kingdom in 2333 BC. The earliest recorded version of the Dangun legend appears in the 13th century Samguk Yusa, which cites China's Book of Wei and Korea's lost historical record Gogi (古記).

Legend
Dangun's ancestry legend begins with his grandfather Hwanin (환인; 桓因), the "Lord of Heaven". Hwanin had a son, Hwanung, who yearned to live on the earth among the valleys and the mountains. Hwanin permitted Hwanung and 3,000 followers to descend onto Baekdu Mountain, where Hwanung founded Sinsi (신시; 神市, "City of God"). Along with his ministers of clouds, rain, and wind, he instituted laws and moral codes and taught humans various arts, medicine, and agriculture. Legend attributes the development of acupuncture and moxibustion to Dangun.

A tiger and a bear prayed to Hwanung that they might become human. Upon hearing their prayers, Hwanung gave them 20 cloves of garlic and a bundle of mugwort, ordering them to eat only this sacred food and remain out of the sunlight for 100 days. The tiger gave up after about twenty days and left the cave. However, the bear remained and was transformed into a woman. The bear and the tiger are said to represent two tribes that sought the favor of the heavenly prince.

The bear-woman (Ungnyeo; 웅녀; 熊女) was grateful and made offerings to Hwanung. However, she lacked a husband, and soon became sad and prayed beneath a "Sindansu" (신단수; 神檀樹, "Divine Betula") tree to be blessed with a child. Hwanung, moved by her prayers, took her for his wife and soon she gave birth to a son, who was named Dangun Wanggeom.

Dangun ascended to the throne, built the walled city of Asadal, situated near Pyongyang (the location is disputed) and called the kingdom Joseon—referred to today as "Old/Ancient Joseon" (Korean: "Gojoseon") so as not to be confused with the Joseon kingdom which occurred much later. He then moved his capital to Asadal on Mount Baegak (or Mount Gunghol).

General Sherman incident

The General Sherman incident was the destruction of an armed merchant marine side-wheel steamer that visited Korea in 1866. It was an important catalyst to the end of Korean isolationism in the 19th century. After passing the Keupsa Gate without permission from the Koreans, the United States merchant ship was attacked and fought for several days before being destroyed.


Background
In the mid-19th century, European nations and the United States were eager to open up new trade in Asia, and began establishing trade in China and southeast Asia. Japan was also opened up to trade after Commodore Matthew Perry sailed into Uraga Harbor near Edo (modern Tokyo) on July 8, 1853, and under the threat of force Japan signed the Convention of Kanagawa in 1854. As early as 1832 discussions of opening up Korea were made by the captain of the USS Peacock, Edmund Roberts, yet in 1844 a draft by the United States Congress was shelved due to lack of interest.

The first contact between the U.S. and Korea was not in any way hostile, and in 1853 the USS South America, a US gunboat, visited Busan for 10 days while en route to Japan and had dined with local Korean officials. Several Americans who were shipwrecked in Korea between 1855, 1865 and 1866 were treated well and sent to China for repatriation. However, the Joseon Dynasty court which ruled Korea was well aware of the colonization of China as a result of the First as well as the Second Opium War and maintained a strict policy of isolationism to avoid a similar fate.

The United States expedition to Korea, the Shinmiyangyo in 1871

The United States expedition to Korea, the Shinmiyangyo, or simply the Korean Expedition, in 1871, was the first American military action in Korea. It took place predominantly on and around the Korean island of Ganghwa. The reason for the presence of the American naval force in Korea was to support an American diplomatic delegation sent to establish trade and political relations with the peninsular nation, to ascertain the fate of the merchant ship General Sherman, and to establish a treaty assuring aid for shipwrecked sailors. When Korean shore batteries attacked two American warships on June 1, 1871, a punitive expedition was launched ten days later after the commanding American admiral failed to receive an official apology from the Koreans. The isolationist nature of the Joseon Dynasty government and the assertiveness of the Americans led to a misunderstanding between the two parties that changed a diplomatic expedition into an armed conflict. On June 10, about 650 Americans landed and captured several forts, killing over 200 Korean troops with a loss of only three dead. Korea continued to refuse to negotiate with the United States until 1882.

Aftermath

The United States was not able to achieve its objectives diplomatically, as the Koreans refused to negotiate. In fact, these events led the regent Daewon-gun to strengthen his policy of isolation and issue a national proclamation against appeasing foreigners. However, in 1876, Korea established a trade treaty with Japan after Japanese ships approached Ganghwado and threatened to fire on Seoul. Treaties with European countries and the U.S. soon followed.
Nine sailors and six Marines were awarded the Medal of Honor, the first for actions in a foreign conflict.

Heungseon Daewongun

Heungseon Daewongun (흥선대원군, 1820–1898) or The Daewongun (대원군), Guktaegong (국태공, ‘The Great Archduke’) or formally Heungseon Heonui Daewonwang (흥선헌의대원왕) and also known to period western diplomats as Prince Gung, was the title of Yi Ha-eung, regent of Joseon during the minority of King Gojong in the 1860s and until his death a key political figure of late Joseon Korea.
Daewongun literally translates as "prince of the great court", a title customarily granted to the father of the reigning monarch when that father did not reign himself (usually because his son had been adopted as heir of a relative who did reign). While there had been three other Daewongun during the Joseon Dynasty, so dominant a place did Yi Ha-eung have in the history of the late Joseon dynasty that the term Daewongun usually refers specifically to him.


Life

Regent
The Daewongun was the father of the penultimate Joseon monarch Gojong, and for many years during Gojong's minority, and even afterward, he effectively wielded royal power.

During the mid-1860s Heungseon Daewongun was the main proponent of isolationism and the instrument of the persecution of native and foreign Catholics, policies that led directly to the conflict with France in 1866 (the so-called byeong-in yangyo) and the United States expedition to Korea in 1871. The early years of Heungseon Daewongun's rule also witnessed a large effort to restore the largely dilapidated Gyeongbok Palace, the seat of royal authority. During Heungseon Daewongun's reign, faction politics, Seowon and power wielded by the Andong Kim clan completely disappeared.

Struggle with Empress Myeongseong
His political life was characterized by struggles with Empress Myeongseong of the Min clan, the wife of the king. He had himself chosen her as the bride for his son, wrongfully anticipating she would remain a docile figure indulgent to his own political ambitions. The Daewongun's period as regent came to an end in 1873 in the face of growing opposition by his mature son, his willful daughter-in-law and the Min clan, as well as by the country's powerful Confucian officialdom.
In 1882, however, the Daewongun was briefly restored to power in the Imo Incident. But the Qing general, Yuan Shikai soon had the Daewongun abducted by Chinese troops and taken to China, thus foiling his return to power. Four years later the Daewongun returned to Korea.

Return to Korea
After his return, he lived at his own private residence at Unhyeon Palace in central Seoul not far from the royal compound at Gyeongbok Palace. He made one more brief return to power in 1895, chosen by the Japanese to oversee the Gabo reform government, but he was soon removed from power when his commitment to the reform program became suspect. He died at Unhyeon Palace in 1898.
In 1908, he was raised to the rank of Imperial Prince by his grandson, Emperor Sunjong, with the title of Heungseon Heonui Daewonwang.

French campaign against Korea of 1866

The French campaign against Korea of 1866 is also known as Byeong-in yangyo (Western disturbance of the byeong-in year). It refers to the French invasion of Ganghwa Island in Korea in retaliation for the earlier execution by Korea's Joseon Dynasty of French Catholic priests proselytizing in that country. The encounter, which lasted nearly six weeks, was the first armed encounter between Korea and a Western power. The overall result was a French retreat and a check on its influence in the region. The violent encounter also confirmed Korea in its isolationism for another decade, until Japan forced it to end its isolationism in 1876 through the threat of military force (see Treaty of Ganghwa).

Ganghwa Island

Ganghwa Island is an island in the estuary of the Han River, on the west coast of South Korea. Ganghwa Island is separated from Gimpo, on the mainland, by a narrow channel, which is spanned by two bridges. The main channel of the Han River separates the island from Gaeseong in North Korea.
About 65,500 people live on the island. With an area of 302.4 km² (116.8 sq mi), it constitutes most of Ganghwa County, a division of Incheon Municipality. About half of the island's population reside in Ganghwa-eup, Ganghwa Town, in the northeastern part of the island. The island's highest point is Mani-san, 469 m (1,539 ft) above sea level. The island measures 28 kilometres (17 mi) long and 22 kilometres (14 mi) wide, and is the 4th largest island in South Korea.
Historically, it is significant as being the location of separate punitive incursions; by the French in 1866, the United States in 1871, and the Japanese in 1875 when Korea was emerging from isolation.
