First Sino-Japanese War: After capturing the Chinese city of Port Arthur, the Japanese army began a massacre of the city's soldiers and civilians.

The First Sino-Japanese War, or the First China–Japan War, was a conflict between the Qing dynasty of China and the Empire of Japan primarily over influence in Korea. In Chinese it is commonly known as the Jiawu War. After more than six months of unbroken successes by Japanese land and naval forces and the loss of the ports of Lüshunkou and Weihaiwei, the Qing government sued for peace in February 1895 and signed the unequal Treaty of Shimonoseki two months later, ending the war.

The Battle of Lüshunkou was a land battle of the First Sino-Japanese War. It took place on 21 November 1894, in Lüshunkou, Manchuria between the forces of the Empire of Japan and the Qing dynasty. It is sometimes referred to archaically in western sources as the Battle of Port Arthur.

Lüshunkou District is a district of Dalian, Liaoning province, China. The district's area is 512.15 km² (197.74 sq mi) and its permanent population as of 2020 is 398,579.

The Port Arthur massacre took place during the First Sino-Japanese War from 21 November 1894 for three days, in the Chinese coastal city of Port Arthur, when advance elements of the First Division of the Japanese Second Army under the command of General Yamaji Motoharu (1841–1897) killed somewhere between 2,600 civilians and 20,000 people including Chinese soldiers, although one eyewitness reporter estimated a total death toll of 60,000, including civilians, soldiers, and residents of the outlying rural district.
