Archaeological excavations carried out near
Hà Giang city at Đồi Thông (Pine Hill) have established the region's antiquity to about 30,000 years ago. During the Bronze Age
Tày Yu tribes with culturally rich traditions ruled over the region; archaeological findings in the form of bronze drums of that age used for ceremonial purposes are used even to the present day by the
Lô Lô and Pu Péo tribes of the region (
Mèo Vạc, Hà Giang province). Before 1975, Hà Giang comprised the districts of
Đồng Văn,
Vị Xuyên,
Xín Mần,
Yên Minh,
Hoàng Su Phì,
Bắc Quang,
Thanh Thủy, and
Quản Bạ. On November 18, 1983,
Bắc Mê District was split from
Vị Xuyên District; one commune from
Xín Mần District was placed under
Hoàng Su Phì District, two communes from Hoàng Su Phì District were placed under Xín Mần District, three communes from
Bắc Quang District were placed under Xín Mần District, three communes from Bắc Quang District were placed under Hoàng Su Phì District, and one town and five communes from Bắc Quang District were placed under Vị Xuyên District. On August 12, 1991, Hà Tuyên Province was re-divided into
Tuyên Quang Province and Hà Giang Province. Hà Giang Province comprised
Hà Giang city,
Bắc Mê District,
Bắc Quang District,
Đồng Văn District,
Hoàng Su Phì District,
Mèo Vạc District,
Quản Bạ District,
Vị Xuyên District,
Xín Mần District, and
Yên Minh District—a total of one town and nine districts. The provincial capital was Hà Giang Town. On December 1, 2003,
Quang Bình District was split from
Bắc Quang District,
Hoàng Su Phì District, and
Xín Mần District. On June 23, 2006, the communes of Phú Linh, Kim Sơn, and Kim Linh in Hà Giang Town were placed under the administration of
Vị Xuyên District; part of Quang Trung Ward in Hà Giang Town was placed under the Phong Quang Commune of Vị Xuyên District. The communes of Phương Độ and Phương Thiện in Vị Xuyên District were placed under the administration of Hà Giang Town. On September 27, 2010, Hà Giang Town was upgraded to
Hà Giang city. On June 12, 2025, Hà Giang Province and
Tuyên Quang Province were merged to form a new
Tuyên Quang Province. The former province was restructured into 2 wards. The province's name derived from the
Sino-Vietnamese 河江.
H'Mông lords of Sà Phìn The history of the
Hmong lords of the northern region of the province, bordering China (
Đồng Văn and
Mèo Vạc), is integral to the province, as the Hmong people have dominated the region from the late 18th century. The Vương family of the Huang clan established their rule at Đồng Văn and Mèo Vạc, which was endorsed by the
Nguyễn kings. During
French colonial rule, the French further supported the lords in their hold on the border territory. Vương Chính Đức was recognized as the king of the Hmong in 1900. A palace was built between 1902 and 1903 at Sà Phìn (16 km west of Đồng Văn town). The lord's loyalty to the French was evident in the support that they got from him during their campaign to put down a rebellion launched by the local tribes. In recognition, the lord was given the rank of a general in the French Army (a fully uniformed picture of the lord is seen in the interior rooms of the palace). Increasing opposition by the Vietnamese to French rule saw the lord adopting a neutral stance. Vương Chú Sển, who succeeded his father after the latter's death in 1944, however, pledged support to
Ho Chi Minh. The historical palace of the Vương lord was built in the traditional style of northeast Asian royal palaces. It has four double-storied wings, which are linked by three open courtyards. A moat surrounds the palace. Tombs of the royal family members, which are intricately carved in wood, are located outside the palace walls. Only the walls of the buildings are made of bricks, while the rest is made of wood. ==Administrative divisions==
