Historical evolution

Datong District was subordinate to Shouzhou (or Shouchun county) before Yuan Dynasty.

Huaiyuan County was established from the Yuan Dynasty to the 28th year of the Yuan Dynasty (1291).

From yuan, Ming and Qing Dynasties to the eve of liberation, it was under the jurisdiction of Huaiyuan County.

In 1910, Duan Shuyun, a member of Xiaoxian County, came to the district to build a coal mine. In 1911, he officially registered "Datong coal mining company", which is the origin of the name "Datong".

On March 27, 1930, the Construction Committee of the national government invested in the establishment of Huainan Coal Mine Bureau in jiulonggang, which was the source of the official Huainan coal mine. In June 1938, Japanese invaders occupied Datong and seized Datong and jiulonggang coal mines. In 1945, Japan surrendered and Datong Mine and jiulonggang mine were taken over by the national government and Song Ziwen financial group. During the period of the Republic of China, with the formation of Huainan mining area, Luohe and Shangyao areas were under the jurisdiction of Huaiyuan, while Datong and jiulonggang areas were under the jurisdiction of mining area.

After the liberation of Datong on January 18, 1949, township governments were set up in Datong and jiulonggang respectively, which were subordinate to Huainan Coal Mining Special Administrative Region. In November 1949, it was changed into Datong town and jiulonggang Town, which belong to Huainan mining area.

From September 1950 to may 1953, it was under the jurisdiction of Huainan Municipal People's government.

In January 1967, the rebels "seized power", the party and government organizations were paralyzed, and the "leftist" forces carried out military control.

On March 28, 1968, Datong District changed its name to Dongfeng District, and the Revolutionary Committee of Dongfeng district was established. The former government working organization was canceled, and the office, political department, production headquarters and people's security department were set up. Revolutionary committees or revolutionary leading groups have also been set up at the grassroots level.

In July 1972, according to the notice of the municipal Revolutionary Committee, Dongfeng District, which was renamed at the beginning of the "Cultural Revolution", was restored to Datong District.

In August 1980, the Eighth People's Congress of Datong District was held, and the Revolutionary Committee of Datong District was renamed Datong District People's government.

In May 1983, in accordance with the spirit of the reform of the agricultural production system, the people's commune was abolished and the Township People's government was re established.

In December 1965, a subdistrict office was set up in Datong. During this period, due to the vast rural area, the crisscross of urban and rural areas, the construction of political power was in a transitional state, and there was no unified political leadership in the whole region. Rural, urban, industrial and mining areas belong to their respective superior leaders, and the division attribution also changes frequently.

In March 1969, Luohe, Yaohe, Shangyao and Gongji people's communes were put under the jurisdiction of Datong. So far, the division and ownership of Datong District have been basically finalized, namely, Datong and jiulonggang streets, and Shangyao, Yaohe, Luohe, Gongji and huaifeng five people's communes.

In February 1992, the three townships, two towns and two streets under its jurisdiction were merged into three towns and one street. That is, Shangyao town and Yaohe township are merged to form a new Shangyao town; Luohe town and Gongji township are merged to form a new Luohe town; huaifeng Township and jiulonggang Street are merged to form a new jiulonggang town; Datong Street is retained.
