Lang Son is a province in far northern Vietnam, bordering Guangxi province in China. Its capital is also Lang Son, which is a strategically important town at the border with China. In fact, Lang Son province is only 137 kilometres (85 mi) northeast of Hanoi by rail and road. Lang Son province borders China in the north and Cao Bang Province the northwest, Ha Bac Province on the south, Quang Ninh Province starting on the south and extending to the eastern border and Thái Nguyên Province to the west. The province covers an area of 8327.6 square kilometres and as of 2008 it had a population of 759,000 people.
The province’s name derives from a Sino-Vietnamese word.
History of the province is the history of Lang Son town. Ancient history is traced to the Bronze Age. This period is marked by the trade route that existed between China and India that passed from the Red River Delta through Nanning to Guangzhou. 7000 – 9000 years ago the limestone caves of the province were inhabited by early settlers of the Bac Son culture.
The Dinh kings (968-980) encouraged the growth of trade in the region and requested the Sung emperors of China that they establish trade relations at Yong Zhou. The Chinese Annals have revealed that the Vietnamese traded perfumes, elephant ivories, rhinoceros horns, gold, silver and salt in return for Chinese fabrics. Later, under the Lý Dynasty an extensive market was established at Vinh Bình on the Ky Cùng River.
On 4 April 1406, as a Chinese Ming envoy crossed the border into Lang Son, Ho Quý Ly’s forces ambushed them and killed the Tran prince that the Ming were escorting back. Consequently, the Yongle Emperor (of Ming China) launched a punitive expedition against him due to this hostile act. During the reign of the Ming Dynasty, during the period 1527 and 1592, Lang Son was vastly fortified in view of its strategic importance at the border, which are seen even now; a citadel of this dynasty is located to the west of the Lang Son town on a lime stone rock outcrop.
Lang Son provinces was one of the 13 original provinces in northern Vietnam under the reign of Emperor Minh Mang in 1831. Then since the establishment of the Nguyen Dynasty in 1802 until then, northern Vietnam had been under the rule of a viceroy.
The town was occupied by the French in 1885 when it was a very prosperous town. The French converted it into a military base considered as important to their other base in Cao Bang. In 1906, archaeologist Henri Mansuy discovered the Tham Kanh cave near Pho Binh Gia which he named the Ho Binh Gia. He unearthed unique stone implements and human remains. In 1922-25 M. Coloni extensively explored Lang Son province and identified 43 sites related to the ancient Bac Son culture in the mountains.
During the Second World War, even though the Japanese had signed an agreement with Vichy Indo China, they soon reneged on the Agreement, without waiting for the ink to dry on the accord, and launched an offensive on Vietnam by withdrawing their troops from China. They crossed the Vietnam China border and entered 12 kilometres (7.5 mi) inside, very close to the Lang Son railway station. The Japanese attacked on 22 September 1940 and by the 25th they captured Lang Son province. However, Vichy had lodged a protest with Emperor Hirohito for the breach of the agreement signed between the two countries, which resulted in a ceasefire to the hostilities by the evening of 26 September, and soon Lang Son was reoccupied by the Vichy forces.
After Ho Chi Minh’s government was established in September 1945, Japanese had surrendered to the British and Indian Army, under the terms of the Potsdam Conference, to the south of the 16th parallel, while the Chinese Nationalist Party (the Kuomintang). As strategy, Ho Chi Minh entered into an agreement with the French so that he could face any threat from the Chinese and a Franco-Vietnamese agreement was signed. This provided for a free Vietnam within the French Union and the Indochinese federation.
However, the French launched an offensive against the Viet Minh in October 1947 with Lang Son as a their base. Surprisingly, the Viet Minh managed to thwart the French Offensive and forced the French to withdraw to Lang Son. Finally, the Viet Minh pursue the French Army, they had a very decisive victory on Highway 4 and they had to finally withdraw from Lang Son province. This marked the beginning of First Indochina War.
In 1950 the Vietminh took control of the province and the town. During February 1979, the Chinese invaded Vietnam through the border town of Don Dong (18 kilometres (11 mi) to the north of Long Son town). In this war, which lasted for five days, 600,000 soldiers had descended on Vietnam; Lang Son town was the major town that received the major thrust of 200,000 soldiers from China and occupied the capital city of the Northern Province. However, the Vietnamese had the last say as the Vietnamese army was successful in defeating the Chinese army, which bid a hasty retreat. This was has achieved the status of a folk lore in the province.
The frontier village, which became famous during the war with China, has remnants of the war on display to the visitors. However, the border has been rebuilt and brisk trade flourishes between Vietnam and China through this town. During the Chinese invasion in 1959 the Lan Son town was also severely damaged, however it has been rebuilt since then. The old part of the town, near the Kyu Kung River has some interesting historical sites.
