Tianjin
During the Boxer rebellion and its aftermath 1899-1901, Austria-Hungary participated in the Eight-Nation Alliance and helped in suppressing the rising. However, Austria sent by far the smallest force of any of the combatant nation. Only one warship and a force of only 75 marines were despatched.
Even so, on 7 September 1901, Austria gained a concession zone in Tianjin as part of the reward for its contribution to the Allies. The Austrian concession zone was 150 acres (0.61 km2) in area, slightly larger than the Italian, but smaller than the Belgian zone. The self-contained concession had its own prison, school, barracks and hospital. It also contained the Austro-Hungarian consulate and its citizens were under Austrian, not Chinese, rule. If they committed a crime on Chinese soil, they could be tried in their own courts.
Though it was provided with a small garrison, Austria proved unable, due to World War I, to maintain control of its concession. The concession zone was swiftly occupied by China at the Chinese declaration of war on the Central Powers and on 14 August 1917 the lease was terminated, (along with that of the larger German concession in the same city). Austria finally abandoned all claim to it on 10 September 1919. Hungary made a similar recognition in 1920.
However, despite its relatively short life-span (only 16 years in all), the Austrians have left their mark on that area of the city, as can be seen in the wealth of Austrian architecture that stands in the city to this day.
