Historically, international condominiums have been rare, but they have existed in various forms. One example is the condominium of the Sudan, which was jointly administered by the United Kingdom and Egypt from 1899 until Sudan's independence in 1956. Another example is the New Hebrides, now known as Vanuatu, which was jointly administered by France and the United Kingdom until its independence in 1980.
These arrangements often arise from historical treaties or agreements, and the specific terms of governance and sovereignty can vary widely depending on the nature of the condominium.
