Ganghwa Island, also known by its native name Ganghwado, is a South Korean island in the estuary of the Han River. It lies in the Yellow Sea off Korea's west coast, separated from Gimpo on the South Korean mainland by a narrow channel spanned by two bridges and from Kaesong (Gaeseong) in North Korea by the main channel of the Han River.

The island is strategically located, controlling access to the river which runs through the former Joseon and present South Korean capital Seoul. Its fortifications were repeatedly attacked during the 19th century. With an area of 302.4 km2 (116.8 sq mi), it now constitutes most of Ganghwa County, a division of Incheon Municipality. It has a population of about 65,500 people, half of whom live in Ganghwa Town (Ganghwa-eup) on the northeast.

Name[edit]

"Ganghwado" or "Ganghwa-do" (Korean: 강화도, formerly ) is Korean for "Island Made Prosperous", "Illustrious", or "Flourishing by the River" in reference to its formation from the silt carried downriver by the Han. Former romanizations include Kang-hoa[1] and Kang-hwa.

Geography[edit]

The island lies in the estuary of Korea's Han River. It is 302.4 km2 (116.8 sq mi), measuring 28 kilometers (17 mi) long and 22 kilometers (14 mi) wide, making it the 4th largest island in South Korea. Its highest point is Mani-san (469 m or 1,539 ft above sea level).

History[edit]

As the location of the primary fortifications protecting the Joseon capital of Seoul from foreign invasion, Ganghwa Island was the site of several punitive expeditions during the 19th century. The mass execution of Catholic French missionaries and Korean converts under the ministry of the Heungseon Daewongun in the mid-1860s led to a French invasion in 1866 which held the island for several weeks, although Admiral Roze was unable to sail up the shallow and uncharted Han River and fortified monasteries prevented overland incursion. In 1871, a Korean assault on an American diplomatic mission led to the Battle of Ganghwa. Rear Admiral Rodgers took five forts on the island but withdrew after the Koreans refused to meet for negotiations. Following a diplomatic incident related to Korea's refusal to recognize the imperial status of the sovereign of Japan in 1868, the forts at Ganghwa fired upon a Japanese boat from the surveying gunship Un'yō in 1875. During the Japanese Battle of Ganghwa, the Un'yō's captain Inoue Yoshika silenced the batteries with superior firepower, then landed a raiding force which plundered local communities. The Imperial Japanese Navy then blockaded the area and compelled the 1876 Treaty of Ganghwa, which opened Korea to Japanese commerce. When the Mongolia aggression Goryeo, Choe-woo the Goryeo's general changed the capital to Ganghwa at sixth aggression. And they prepared the war. At that time, Goryeo's religion was Buddhism. They want to save their country, so they borrowed the power of Buddha. In this process, the Tripitaka Koreana was made. The Tripitaka Koreana was called Palmandaejanggyeong. It is comprehensive collection of 80,000 Buddhist scriptures.

Invasion of Korea by the three U.S. warships in 1871.

1) Cause

 United States expedition to Korea caused by the General Sherman incident.

What is the General Sherman incident?

 ln 1866 the General Sherman arrived to Pyongyang through the Daedong River.

The owner of this ship was American but the ship's captain was Dane and crews were Chinese and British. One of them was pastor Thomas, who came for missionary work to Joseon. Initially, Pyongyang governor Park Gyu-su, who was Park Ji-won’s grandson, informed about his refusal of the trade and advised them to go back.

People of Pyongyang gave pork and chicken to them, but they ignored even 

kidnapping Lee Ik-Hyun who was Joseon soldier and shooting a cannon. So 7 Pyongyang people died. Finally, citizens and Park Gyu-su were furious. Park Gyu-su ordered to shoot the ship. The General Sherman and all the crew was burned.


2) process

 In 1871, America finally decided the Joseon expedition to open a port.    

America ordered Joseon expedition to Asia fleet commander Rogers.

 On June 1, America enforced sounding navigation of Ganghwa strait.

When fleet arrived at Sondolmok, it was attacked from coast Ganghwa artillery unit.

 America scorched Chojijin Fort and took over it with naval gunfire.

And then American army took over Deokjjinjin Fort on June 11th, finally conducted Gwangseongbo operation. After an hour of shelling land and water at the same time, American army captured and took over Gwangseongbo.


3) Result

The scale that damage of human life caused by war. First, damage of the US is: 3 people dead in battle, 10 people wound. On the other hand, the damage to Joseon is: 350 people dead in battle, 20 people wound. It can be seen that the damage to Josean is larger than the damage to the United States.

 Heungseon Daewongun is the father of King Gojong. Heungseon Daewongun erected Cheokhwabi in each region of the whole country. In every Cheokhwabi he put the inscription: “If you don’t fight against the western barbarians, it means you negotiate for peace. And that is selling our country.” What is more, he strengthened the national isolation policy. Therefore, Cheokhwabi is a monument to exclude westerners.
 Cheokhwabi is located in Deokseong-ri, Bureun-myeon, Ganghwa-gun. The name of the one located in Ganghwa-gun is Deokjinjin gyeong-gobi, it is also called ‘Cheokhwabi of the sea.’ There is a sentence in the front of the monument written in characters, that says: ‘it is guarding the sea gate, thus foreign ship can not pass. There is a bullet mark remained on it.

Wetlands[edit]

Tidal wetlands of Ganghwa. The Maehwa Mareum Habitat is located in Choji-ri, Gilsang-myeon, Ganghwa Island, Incheon, Korea. The Maehwa Mareum is registered as a Ramsar-site since October 13, 2008. It is the first time that a wetland in Korea has been registered as a Ramsar-site. The registered area amounts to 3,015 ㎡. The area around the Maehwa Mareum Habitat has been utilized as farmland and was mainly introduced by eco-friendly farming communities. The Maehwa Mareum is home to various species, like the Blackfaced Spoonbill, Chinese Egret, Yellow-spotted Serpent, Seoul Pond Frog, Narrow-mouth Frog and many more. Especially important for the registration as an official Ramsar site, was the endangered plant maehwa mareum that grows in the rice paddies. The Maehwa Mareum nearly faced destruction because of land consolidation. Fortunately, the Korean National Trust, a civil environmental movement that is dedicated to preserve natural and cultural heritage, bought that land and after consultation with local residents, they decided to preserve the land as a rice paddy wetland.


< Definition of Mudflat > In general, if you look at the meaning of the mudflat of mudflat, the tide will be served. A wide flat ground of sand or mud flats on the beach or river

<Ganghwa mudflats > The Ganghwa mudflats are an intermediate resting place where migratory birds eat and relax while migrating to Japan, Australia, and New Zealand. It is also famous for its breeding grounds, which are known as Natural Monument No.205, the world's largest natural monument. They are located between the southern region and Seokmudo Island and other surrounding islands. The Ganghwa mudflats represent one of the best preserved mudflats in Korea, and have a significant importance in economical productivity, natural purification and marine ecosystems.


[Ganghwa mudflats advantage. Necessity]

<Natural purification function> Physical aspect It provides conditions that promote purification more than purification itself, and the excitation of tide and blue is largely affected by this. In the eutrophic waters where there are no tidal flats, nutrients are introduced from the land, suspended organic matter produced in the sea is accumulated on the sea floor, and oxygen is consumed in the process of decomposing it, forming a serious oxygen vacancy.

<The function of natural disaster and climate control>

Wetlands can absorb floods and rainwater, such as natural sponges, by first blocking and absorbing surface water, then slowly releasing it, and at the same time, storing large amounts of water, thereby preventing erosion of the river or coast and reducing flood damage. It is a buffer to protect us from natural disasters because it is a buffer zone for preventing floods caused by forests.

<Ecological function>

Tidal flats are important intermediate destinations for migratory birds migrating along the river, and are used as a place to feed energy or as a place to rest or breed.

Because some species of migratory birds have to pass through certain wetlands, the Ramsar Convention has been enacted to protect the world's most important wetlands, and the biodiversity of the tidal flats in the west coast of Korea is also high.

<Economic value>

The value of the tidal flats is important as a source of natural products. In foreign countries, the development and use of fruits and timber in the coastal wetlands are still in use in Korea.In the future, valuable medicines and new materials may be extracted from the creatures of this area. Therefore, once again, conservation of biodiversity in salt marsh vegetation and tidal flats should be seriously considered. Recently, we developed products like Mudpack in our country,

The number of users of tidal-flat massage is also increasing.

<Cultural function>

In recent years, wetlands have also been used as a leisure space for fishing, bathing, relaxing and sightseeing, and for artists who love nature - photographers, painters, and writers - And the cultural value of it is becoming more important in many ways. Even if you are buried in everyday life, if you go to the tidal flats, you will see the waves and the whirlwind that spread out over the snowy white sand field, the natural reed bed, and the reed forest, You can see the natural scenery you have been drawing in a realistic manner in the tidal flat.

< Creatures of Organisms > Living creatures in the tidal flat Form-form A typical group of creatures that can be found on the mudflats is the shellfish, the algae, and the shellfish that contains the algae. - Forms of Forms The size and shape of the habitat varies greatly depending on the nature of the species and the nature of the environment. The depth from the mudflats to the innermost depths of the oyster bed ranges from centimetres to tens of meters, and generally the depth of the depth is correlated with the diameter of the oyster. In addition, there is a high correlation between the length of the organisms and the depth of the habitat in the same species.

The most common form of habitat is the shape of a " U " or " Y " shaped structure with two or more entrances to the surface of the sediment. This form of habitat is formed by a species of filtration that cools down in the form of sediments or forms of habitat.

- Size of tunnel The habitat of the mudflats is reflected in the habitat of the habitat, ranging from several centimeters to tens of thousands of meters, and differs from the same species, not only in terms of diversity but also in the same species.

In order to cope with poor environmental conditions, the size of the creature in the upper crust of the upper crust can be explained by the survival of the creature's survival patterns, depending on the difference in time, location and temperature.


- Ecological role of habitat It is also a space to store water as well as to cool off. It serves as a shelter to overcome poor environmental conditions.

Increasing deposits of sediments and water in the form of sediments increase the interface between sediments and seawater, increasing the interface between sediments and aquatic waters, and the irrigation activity of the organism facilitates the exchange of material exchanges between the seawater and the water between the layers.

politics-treaty[edit]

Ganghwa Treaty After the Unhyo Incident, Japan demanded unilateral compensation from Joseon. Joseon was coerced to grant Japan the right of extraterritoriality, permission for ocean measurement and the opening of three ports in Pusan, Incheon and Wonsan. Although normally extraterritoriality applies to diplomats, common Japanese who lived in Joseon also gained this right. Before, Joseon was isolated because of the Daewongun’s closed-door policy. By signing the contract Joseon could appear on the global stage. The treaty is considered unequal, and the first step towards Japanese colonialism.

Japan-Korea Treaty of 1882

After Ganghwa treaty, Joseon Dynasty opened ports and accepted advanced civilization from Japan and China actively. In this progress the Im-O Military Revolt occurred because of discrimination between old type army and new type army. After the Im-O Military Revolt, Japan declined politically in Joseon. Japan signed a treaty that damanded compensation for the damage with Joseon. It is Japan-Korea Treaty of 1882. After Japan-Korea Treaty of 1882, leaders of revolt were punished.

Japan-Korea Treaty of 1905

Because of wins in two wars, First Sino-Japanese War and Russo-Japanese Wars, Japan had supremacy to dominate Joseon. Japan got other countries’ agreement to make Korean Empire protectorate of Japan. They contract Anglo-Japanese Alliance with UK, The Katsura-Taft Agreement with the US and the Treaty of Portsmouth with Russia. Finally Japan deprived diplomatic rights of Korean Empire through a treaty. It is Japan-Korea Treaty of 1905

Japan-Korea Annexation Treaty of 1910

Korean Empire signed Japan-Korea Treaty of 1905 and fall into country that lose the sovereignty and get formal name of country. Resident-General of Japan pressed 이완용 to accept an annexation treaty draft in August 16th 1910. So 이완용 signed Japan-Korea Annexation Treaty in August 22th, 1910 . This treaty regulate that sovereignty of all of Korean Empire is transferred to Japan permanently.
