Military occupation is a temporary state, yet some last for decades or even centuries.
Military occupation is defined by hostile control over foreign territory, distinct from permanent annexation. While international law mandates that occupants maintain public order and protect civilians, the reality often diverges. Some occupations persist for generations, challenging the legal expectation that these arrangements remain strictly temporary and subject to specific humanitarian rules.
At its core, military occupation is the exercise of authority by a foreign army over territory that lies outside its own sovereign borders. Unlike colonialism or formal annexation, occupation is legally intended to be a transient condition. The foundation of this framework rests on the principle that sovereignty cannot be unilaterally seized by a foreign power. This concept was codified in the 1907 Hague Convention and later expanded by the 1949 Fourth Geneva Convention, which established strict duties for the occupant, including the protection of civilians and the preservation of public safety.
The legal threshold for occupation is reached when a hostile army effectively establishes control over a region. This status does not require a formal proclamation or a specific number of troops; it is a factual state of submission to the occupant's authority. Notably, the presence of insurgents or guerrilla fighters who intermittently challenge this control does not negate the legal status of the occupation. As established by the 1948 Nuremberg trials, an occupant holds territory only through precarious, temporary control rather than any inherent legal right.
Despite these clear legal definitions, the reality of occupation is often fraught with controversy. Since the establishment of the United Nations in 1945, the prohibition of wars of aggression has made the status of occupied lands a frequent source of international dispute. When an occupant attempts to make its presence permanent through annexation or refuses to acknowledge its role, the situation often becomes a catalyst for further armed conflict. While the 2023 United States Department of Defense Law of War Manual emphasizes that occupation law generally applies only to specific scenarios like belligerent occupation, many territories have remained under foreign control for decades, including instances in Namibia, East Timor, and the West Bank, which has been occupied since 1967.
