World War IWorld War I or the First World War, often abbreviated as WWI or WW1, known contemporaneously as the Great War, was a major global conflict lasting from 1914 to 1918. It was fought between two coalitions, the Allies and the Central Powers. Fighting took place throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. The first decade of the 20th century saw increasing diplomatic tension between the European great powers.
ExtraterritorialityIn international law, extraterritoriality is the state of being exempted from the jurisdiction of local law, usually as the result of diplomatic negotiations. Historically, this primarily applied to individuals, as jurisdiction was usually claimed on peoples rather than on lands. Extraterritoriality can also be partly applied to physical places, such as the immunity granted to diplomatic missions, military bases of foreign countries, or offices of the United Nations.
Condominium (international law)A condominium (plural either condominia, as in Latin, or condominiums) in international law is a political territory (state or border area) in or over which multiple sovereign powers formally agree to share equal dominium (in the sense of sovereignty) and exercise their rights jointly, without dividing it into "national" zones. Although a condominium has always been recognized as a theoretical possibility, condominia have been rare in practice.
Treaty portsTreaty ports (; 条約港) were the port cities in China and Japan that were opened to foreign trade mainly by the unequal treaties forced upon them by Western powers, as well as cities in Korea opened up similarly by the Japanese Empire. List of Chinese treaty ports The British established their first treaty ports in China after the First Opium War by the Treaty of Nanking in 1842. As well as ceding the island of Hong Kong to Great Britain in perpetuity, the treaty also established five treaty ports at Shanghai, Guangzhou (Canton), Ningbo, Fuzhou, and Xiamen (Amoy).
