of this date. In the situation of a territorial cession, there must be a formal peace treaty. However, the occupation does not end with the coming into force of the peace treaty. Example: (1) Puerto Rico after the Spanish–American War. Military government continued in Puerto Rico past the coming into force of the Treaty of Paris of 1898 on April 11, 1899, and only ended on May 1, 1900 with the beginning of Puerto Rico's civil government. Example: (2) Cuba after the Spanish–American War. Military government continued in Cuba past the coming into force of the Treaty of Paris of 1898 on April 11, 1899, and only ended on May 20, 1902 with the beginning of the Republic of Cuba's civil government. Hence, at the most basic level, the terminology of "legally supplanted" is interpreted to mean "legally supplanted by a civil government fully recognized by the national (or "federal") government of the principal occupying power". Examples of occupations In most wars some territory is placed under the authority of the hostile army. Most occupations end with the cessation of hostilities. In some cases the occupied territory is returned and in others the land remains under the control of the occupying power but usually not as militarily occupied territory. Sometimes the status of presences is disputed by a party to the situation. The largest extending territories under military occupation came into existence as the outcome of World War I and World War II: Occupied Enemy Territory Administration (OETA), encompassing much of the Middle East during 1917-1920 - separated to French (OETA North) and British (OETA South) domains; Allied-occupied Germany (1945–49) in the aftermath of World War II Occupation is usually a temporary phase, preceding either the handing back of the territory, or its annexation. A significant number of post-1945 occupations have lasted more than two decades such as the occupations of Namibia by South Africa and of East Timor by Indonesia as well as the ongoing occupations of Northern Cyprus by Turkey and of Western Sahara by Morocco. One of the world's longest ongoing occupation is Israel's occupation of the West Bank, including East Jerusalem and the Gaza Strip (1967–present). Other prolonging belligerent occupations that have been alleged include the occupation by the United Kingdom of the Falkland Islands/Malvinas (1833–present) which Argentina claims this as sovereign territory, of Tibet by PR China (1950), and of the Hawaii by the United
