In 1950, United States of Indonesia dissolved itself into a unitary state and began to divide its component area into provinces. In 1958, by Indonesian law ("Undang-Undang") No. 64/1958, three provinces were established in the Lesser Sunda Islands, namely Bali, West Nusa Tenggara and East Nusa Tenggara. The area of East Nusa Tenggara province included the western part of Timor island, Flores, Sumba and other several small islands in the region. The province was sub-divided into twelve regencies and the City of Kupang, which had regency-level status.
