Dadra, Dadra and Nagar Haveli and Daman and Diu in the context of Nagar Haveli

Dadra and Nagar Haveli and Daman and Diu (IPA: [d̪aːd̪ɾaː nəɡəɾ ɦəʋeːliː, d̪əmən d̪iːʋ]) is a union territory in India. The territory was constituted through the merger of the former territories of Dadra and Nagar Haveli and Daman and Diu. Plans for the proposed merger were announced by the Government of India in July 2019; the necessary legislation was passed in the Parliament of India in December 2019 and came into effect on 26 January 2020. The territory is made up of four separate geographical entities: Dadra, Nagar Haveli, Daman, and the island of Diu. All four areas were formerly part of Portuguese India, with a joint capital at Panjim, Goa. They came under Indian rule in the mid-20th century after the Annexation of Goa and of the Free Dadra and Nagar Haveli. Goa, Daman and Diu were jointly administered until 1987, when Goa was granted statehood after the Konkani language agitation. The current capital is Daman and Silvassa is the largest city.

Dadra and Nagar Haveli district is a district of the union territory of Dadra and Nagar Haveli and Daman and Diu in western India. It is composed of two separate geographical entities: Nagar Haveli, wedged in between Maharashtra and Gujarat states; and, 1 kilometre (0.62 mi) to the north-west, the smaller enclave of Dadra, which is surrounded by Gujarat. Silvassa is the administrative headquarters of Dadra and Nagar Haveli.

Unlike the surrounding areas, Dadra and Nagar Haveli was ruled by the Portuguese from 1783 until the mid-20th century. The area was captured by pro-India forces in 1954 and administered as the de facto state of Free Dadra and Nagar Haveli before being accessioned to India as a union territory, the union territory of Dadra and Nagar Haveli in 1961. The union territory was merged with the neighbouring union territory of Daman and Diu to form the new union territory of "Dadra and Nagar Haveli and Daman and Diu" on 26 January 2020. The territory of Dadra and Nagar Haveli then became one of the three districts of the new union territory, as the Dadra and Nagar Haveli district.
