Battle of Peking: The Eight-Nation Alliance occupies Beijing, China, in a campaign to end the bloody Boxer Rebellion in China.

The Battle of Peking, or historically the Relief of Peking, was the battle fought on 14–15 August 1900 in Beijing, in which the Eight-Nation Alliance relieved the siege of the Peking Legation Quarter during the Boxer Rebellion. From 20 June 1900, Boxers and Imperial Chinese Army troops had besieged foreign diplomats, citizens and soldiers within the legations of Austria-Hungary, Belgium, Britain, France, Italy, The German Empire, Japan, Netherlands, The Russian Empire, Spain and the United States.

The Eight-Nation Alliance was a multinational military coalition that invaded northern China in 1900 during the Boxer Rebellion, with the stated aim of relieving the foreign legations in Beijing, which were being besieged by the popular Boxer militiamen, who were determined to remove foreign imperialism in China. The allied forces consisted of about 45,000 troops from the eight nations of Germany, Japan, Russia, Britain, France, the United States, Italy, and Austria-Hungary. Neither the Chinese nor the quasi-concerted foreign allies issued a formal declaration of war.

The Boxer Rebellion, also known as the Boxer Uprising, was an anti-foreign, anti-imperialist, and anti-Christian uprising in North China between 1899 and 1901, towards the end of the Qing dynasty, by the Society of Righteous and Harmonious Fists, known as the "Boxers" in English due to many of its members having practised Chinese martial arts, which at the time were referred to as "Chinese boxing". It was defeated by the Eight-Nation Alliance of foreign powers.
