Mirroring the system of administrative division in Portugal, Diu district (Distrito de Diu) was established as an administrative division of the Portuguese State of India (Estado da Índia) in the first half of the 19th century. It was headed by a district governor, subordinate to the governor-general of Portuguese India in Goa. The district included the single municipality of Diu, which was further subdivided into civil parishes.
