Threatened by the "Boxers", who were supported by regular Chinese troops, 900 soldiers and civilians from Europe, Japan and the United States, and about 2,800 Chinese Christians took refuge in the Beijing Legation Quarter. The ensuing siege lasted 55 days and was broken by an international military force, which went on to occupy Beijing. This map shows the general layout of the Legation Quarter, which measured approximately 3.2 by 1.6 kilometres. In 1900, it contained 11 legations and several foreign businesses and banks, as well as Chinese quarters. Its population included some 500 citizens of the Western powers and Japan.
