Bao'an County


Bao'an County, formerly named Xin'an County, was a historic county in South China. It roughly follows the administrative boundaries of modern-day Hong Kong and the city of Shenzhen. For most of its history, the administrative center of the county was in Nantou.

History

During the Three Kingdoms, the later Bao'an County, along with Dongguan and Boluo counties, formed a single large district with the name Boluo.
In 331, the Eastern Jin Dynasty established Bao'an County, one of six counties under Dōngguān Prefecture. This prefecture's area included modern Shenzhen and Dongguan. In the second year of the Zhide of Suzong under the Tang Dynasty, Dōngguān was renamed to Dōngguǎn.
, and published in 1866.
In the 27th year of Hongwu Emperor's reign, Hongwu appointed an officer with the title Shou-yu-suo to protect the local population from robbers and vagabonds which increasingly infested the district.
In 1573, the first year of the reign of Wanli of the Ming Dynasty, Xin'an County was established as a separate administrative division of Guangzhou Prefecture. The area was then separated from the old Dongguan County due to military reasons.
, an unequal treaty signed between Qing China and the United Kingdom in 1898, shows that south of the Shenzhen River of Xin'an County was leased out to British government.
Under the Qing Dynasty, Xin'an County was one of the fourteen districts under the department of Guangdong. During the Great Clearance, most of Xin'an County was affected by the coastal evacuation. However Xin'an ceased to be a separate administrative county by the 5th year of Kangxi, and the areas not affected by the evacuation were temporarily absorbed into the adjoining Dongguan County until the lift of the ban in 1669. From 1842 to 1898, 1055.61 km2 out of 3076 km2 of Xin'an County was ceded to the United Kingdom to form Hong Kong.

Cession of Hong Kong

The area commonly referred to as Hong Kong was successively ceded or leased from the county to Britain in 1842, 1860 and 1898 under the Treaty of Nanking, Convention of Peking, and Convention for the Extension of Hong Kong Territory.

Republic of China era

After the founding of the Republic of China in 1913, the name of Xin'an was changed back to Bao'an.

People's Republic of China era

In 1953, Shenzhen replaced Nantou as the administrative centre, due to the increasing prominence of the town as the southern terminus of the Chinese section of the Kowloon Canton Railway.
In 1979, Bao'an County was renamed Shenzhen City after its county town, and most part of Shenzhen city became a Special Economic Zone a year later.
