A unilateral declaration of independence (UDI) is a variant declaration of independence that is established when the government of a constituent entity of a sovereign state declares itself independent from that state, and declares itself a sovereign state, without having a formal agreement with the state that the constituent entity declared its secession from. It was first formally recognized and described as UDI when Rhodesia declared independence in 1965 from the United Kingdom (UK) without an agreement with the UK.
