The pre – Thang Long

The archaeological site at Co Loa shows that humans occurred in the area two thousand years ago, the period of Son Vi culture. But by the time the ice melted and the sea deep into the mainland, the inhabitants of the Neolithic were pushed back to the mountains. Human returned and lived here about 4 or 5 thousand years BC. The archaeological artifacts next phase, from early Bronze Age to the early Iron Age approved that Hanoi were present in all four age culture: Phung Nguyen, Dong Dau, Go Mun and Dong Son. The Hanoi residents lived on farming, animal growing and fishing in that era. This prehistoric period corresponded to the period of the legendary Hung Kings. 3rd century BC, during the war against the Qin army from the north, Thuc Phan decided to base in Co Loa, the Dong Anh district, it is about 15 km far from Hanoi center. The Co Loa became a central urban of politic and society.

The pre – Thang Long

Failure of Thuc Phan in early 2nd century BC ended the independence of Au Lac and started the period of one thousand years by the Chinese feudal domination. Han dynasty period, Au Lac was divided into three districts; Giao Chi, Cuu Chan and Nhat Nam, Hanoi belonged to Giao Chi district at that time. Absent in history during the first five centuries, until about 454-456 year – the time of Liu Tong, Hanoi newly recorded as the central of Tong Binh district. In 544, Ly Bi rose up against Luong family and self-proclaimed as emperor, named the Van Xuan. The descendant of Ly Bi was Ly Phat Tu shaped the capital in Loa, but this independence lasted only till 602. During Duong period, An Nam was divided into 12 stats with 50 districts and Tong Binh was the center of Government colonial An Nam. In 866, a generals of Duong family, Cao Bien built a new strong palace, Tong Binh was renamed Dai La – the capital of Hai Quan province. According to legend, Cao Bien saw a god claiming to be Long Do. Therefore,  the land was also known as Long Do land. In 10th century, after the victory of Ngo Quyen against Han invaders, Loa again became the capital of Vietnam.

After ascending in 1009 at Hoa Lu, King Ly Thai To decided to move the capital to Dai La in 1010. According to a popular legend, when Ly Thai To visited Dai La and saw a dragon flying up, so named Dai La as Thang Long. Thang Long Citadel was limited by three rivers: the Red River in the east, To River in the north and Kim Nguu in the south. Citadel was built near the West Lake with the royal palace and the political process. The rest of the urban was residential area including agriculture wards, industry and commerce. In the 10th century, numerous religious constructions were quickly built, Dien Huu pagoda in the western citadel built in 1049, the Bao Thien pagoda built in 1057, Van Mieu built in 1070 and Quoc Tu Giam built up in 1076 … Only a century later, Thang Long became the center of culture, politics and economy of the country.

Ly Tran Dynasty ruled Dai Vietnam, Thang Long continued to be built. The Citadel was strengthened as well as more new palaces were built up. In 1230, Thang Long was more crowded and divided into 61 wards. Foreign residents, such as the Chinese, Japanese and Indians appeared. Industrial and commercial economy also produced high class people and Thang Long was gathering many scholars and intellectuals like Han Thuyen, Le Van Huu, Chu Van An … In the war with the Yuan, Thang Long citadel was occupied three times but ended in the victory of Dai Viet. At the end of the 14th century, Tran family was decadent and a nobleman named Ho Quy Ly took the power, pressed King Tran moved the capital of Thanh Hoa. When Ho Quy Ly founded Dai Ngu and a new capital named Tay Do in 1400 when he formally enthroned. Thang Long name was changed to Dong Do. But the reign of Ho family existed only in a short time. 1406, Ming sent troops to invade Dai Ngu, Thang Long was occupied and renamed Dong Quan. The fourth period of northern domination started in 1407 and extended to 1428.

Le Loi rose up in arms at Lam Son, he found again the position for the capital. In 1430, the city was renamed Dong Kinh till 1466. Imperial Citadel of Thang Long under the Le Dynasty continued to be expanded. The residential area was divided into two districts of Quang Duc and Vinh Xuong. The city continued to be center of trading within Le family’s control. During the power struggle between the Le, the Mac and Lord Trinh, Thang Long remained the capital position. The political complexity of this period also made city more special and different: The city became the center of real power with the royal city of King Le and Minister Trinh. Thank to the commodity economy and the development of foreign trade, Thang Long Urban entered a period of prosperity and attracted more residents to live. The song “ Kinh Ky is the first and the second is Pho Hien” approved the city was bustling and wealth at that time. This stage was also known as Ke Cho. Thang Long’s population esimated about 1 million people about 2 thousand roof.

Summer of 1786, the Tay Son army carried out to the north to overthrow the government of Trinh family, ending two centuries separated by Cochin – Tonkin. After Nguyen Hue together with Tay Son returned to the south, Thanh invaded Dai Viet in 1788. In Phu Xuan, Hue took the throne on 22th of December in 1788 and sent troops to the north. After winning the battle Ngoc Hoi – Dong Da, Tay Son reigned Dai Viet with new capital named Phu Xuan, Thang Long became the capital of the northern as the capital city of Tonkin today.

Tay Son dynasty collapsed after a short time, Gia Long came to the throne in 1802 and took the capital in Phu Xuan, starting the Nguyen dynasty. In 1805, Gia Long broke the old citadel of Thang Long and built new building which remained till today. The new citadel was surrounded by the Phan Dinh Phung, Hung Vuong, Tran Phu and Phung Hung street.  In 1831, in the administrative reform of Minh Mang, Nation was divided into 29 provinces, Thang Long belonged to Hanoi province. It means the city inside of rivers.

Hanoi economy first half of the 19th century was also different from previous Thang Long. Wards and Village in the West and South specialized in agriculture and the area in the East focused on trade, craft that made urban face of Hanoi. Besides, more religious samples appeared such as Ngoc Son Temple, Bao An Temple.

In 1858, French started invading Indochina. After capturing three Southern Provinces, the French army under Francis Garnier’s leadership headed toward Hanoi in November 1873. Although Nguyen dynasty, people continued to fight against the French under the command of Nguyen Tri Phuong and Hoang Dieu. In 1884, Tu Duc signed a peace treaty that the French took over the whole territory of Vietnam, Hanoi also entered the colonial period.

In 19th July of 1888, French President Sadi Carnot signed a decree to establish the city of Hanoi. Hanoi had a small area covering 2 Tho Xuong district and Vinh Thuan district of Hoai Duc. The city consisted  the area of ​​Hue City, Dai Co Viet, Kham Thien, Thuy Khue Street, West Lake to Long Bien Bridge. 3 districts: Hoai Duc, Thuong Tin, Ung Hoa belonged to Ha Dong province.

In 1902, Hanoi became the capital of the entire Indochinese Federation.  Due to the planning of the French, the city gradually had a new face.  The Nguyen dynasty gradually was down, almost entirely distroyed in 1897.  The only remaining Flag, Cua Bac with bullet wounds 1873, Doan Mon and railing stone dragons in the old citadel. In 1901,  The government offices, the post office, Bank, Housing Management Officer, Opera House, Long Bien Bridge, Hanoi Railway Station, squares, hospitals, … were built. Hanoi also had a race horse course, the Christian church, the University of Medicine, University of Indochina, University of Arts, the College of Justice, Agriculture and Forestry and factories of the alcohol, salt, textiles, electricity, water … When the French capital came to Hanoi more, cinemas, theaters, hotels … gradually appeared, the street was changed to match with new residents. In 1921, the city had about 4,000 European residents and 100,000 local residents.

The capitalists caused change to Vietnam’s cultural. Western culture followed by the French to Vietnam that made the social unstable. No longer a feudal citadel existed, Hanoi had more or less the shadow of a European city. The city continued to hold the central role of knowledge and art of the country, where the new poets, musicians and intellectuals, modern music, famous scholar stayed.

In the mid-20th century, Hanoi beared another complex period of history.  Japanese attacked Indochina in 1940 that brought Vietnam under the rule of both the French and the Japanese empire. In 9th of March , 1945,French took a coup against Japanese military. Just five months later, the country surrendered to the Allies, ending the Second World War. In that good time, the Vietnamese Viet Minh held the August Revolution sucessfully, overthrowed the Empire State Vietnam, forcing King Bao Dai abdicated, gained the power in Vietnam. In 2rd of September, 1945, Ho Chi Minh read the Declaration of Independence at Ba Dinh Square, found Vietnam Democratic Republic with Hanoi Capital. After independence, the city was divided into neighborhoods, gardens, streets, like Avenue (Avenue) Paul Doumer renamed as Nhan Quyen, street (Rue de la) was renamed as Dan Quyen, avenue Puginier renamed Democratic Republic, Ollivier Street remaned as Happiness, change the way Dr Morel into Freedom, …

In late 1945, the French army returned to Indochina. After the negotiations failed, Indochina War erupted in December 1946 and Hanoi was again in French’s control. In 1954, the victory of Dien Bien Phu helped people regain the northern Vietnam, Hanoi continued to hold the capital position of the Democratic Republic of Vietnam. At the time of takeover, the city consisted of four urban districts and 34 towns, 37,000 people and four districts with 45 communes and 16,000 residents. In late 1950s and early 1960s, Hanoi repeatedly changed administrative and boundaries. In 1958, the four urban districts were abolished and replaced by the 12 streets. In 1959, the urban area was divided into 8 Quarters and had 4 more suburban districts. In April of 1961, Parliament decided to extend the boundaries of Hanoi, merging some of Ha Dong commune, Bac Ninh, Vinh Phuc and Hung Yen. The whole city had an area of ​​584 km², Population 91,000. In 31th of May, 1961, four inner-city neighborhood of Hoan Kiem, Hai Ba Trung, Ba Dinh, Dong Da and four suburban districts of Dong Anh, Gia Lam, Thanh Tri, Tu Liem were established.

As the Vietnam War escalated, Hanoi suffered direct attacks from the United States. Particularly in Operation Linebacker II in 1972, about 2,200 people were killed in the North, the number of victims in Hanoi were estimated to be 1,318 people. Many agencies, schools must be evacuated to neighboring provinces. After the war, Hanoi continued its role in the national capital of unified Vietnam and expaned to other surrounding provinces.

After the subsidy period, from the late 1990s, economic increased up rapidly in Hanoi suburbs. The development also caused consequences; the city was not planed well, the city traffic jams often happened due to number of motorcycles. Many neighborhoods suffered from the heavy rain. Population density is too high, causing the inner population to live in poor condition and lack of facilities. In 2003, 30% of the population lives below the Hanoi 3 m² per person. Many architectural heritages disappeared, replaced by clutter houses in the streets. Hanoi is a city with uneven development between urban districts and suburban districts, many people still did not have the necessary living conditions. In addition, Hanoi is currently one of the most polluted cities in Asia and the most polluted cities in Southeast Asia.Hanoi has organized successful Party Congress 15th 2015 with the goal to develop into an industrial city with modern trends, the administrative center of national politics, major economic and international exchanges, cultural and educational center of Vietnam.
