ビントゥアン省
Much of what is now Bình Thuận Province was part of the Cham principality of Panduranga, which had its political centre in neighbouring Ninh Thuận Province. It was the last independent principality after the fall of Vijaya in 1471. Bình Thuận was later incorporated into Vietnam, while Ninh Thuận remained independent longer, until 1832. Before 1976, Bình Thuận Province was much smaller because much of the west was in the separate Bình Tuy Province). Bình Tuy, Bình Thuận and Ninh Thuận were merged in 1976 to form . It was divided again into Ninh Thuận and Binh Thuận in 1991, while Bình Tuy remained part of Bình Thuận Province.
