History
Prehistorically, it was inhabited by Dongyi tribes, and it was annexed into China Proper by the state of Qi in 567 B.C.

Before the 14th century, Weihai was a minor fishing settlement. In 1398, during the Ming dynasty, it became a military stronghold (wei) to defend against raids by the wokou. The fortification at Weihai was constructed in 1403, and contained walls almost 2 miles (3.2 km) in circumference.

Weihaiwei was the base for the Beiyang Fleet during the Qing Dynasty. In 1895, the Japanese captured it in the Battle of Weihaiwei, which is regarded as the last major battle of the First Sino-Japanese War. The Japanese then evacuated Weihaiwei on 24 May 1898, after which it was occupied by the British.

The core of Weihai (now Huancui District) was ruled by the British from 1 July 1898 to 1930 under lease agreement with the Chinese empire, with Port Edward (the center of the original Weihai city, now in Huancui District) serving as the capital. A Royal Navy base was built on Liugong Island.

Weihaiwei became an integral part of China after it was returned to the Republic of China on 1 October 1930, but Liugong Island and its facilities were leased back to the U.K. until 1940.

Weihaiwei was occupied by the Japanese from 1938 to 1945. There was a withdrawal of most British forces and supplies from Liugong Island, and finally a Japanese military landing and occupation of the island in 1940.

The region was formally incorporated into Shandong province on 10 May 1945. In 1949, Weihaiwei City was established, and its name was shortened to Weihai after the Communist revolution.

Since 2003, a replica of the Chinese battleship Dingyuan has been anchored here as a museum ship and memorial for Chinese veterans of the First Sino-Japanese War.
