Dadra and Nagar Haveli district
district of Dadra and Nagar Haveli and Daman and Diu and former union territory
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 acceding 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.
History
Pre-Portuguese era
The history of Dadra and Nagar Haveli begins with the defeat of the Koli chieftains of the region by the Rajput kings. In the year 1262, a Rajput prince from Rajasthan named Ram Singh established himself as the ruler of Ramnagar, the present-day Dharampur, which consisted of 8 parganas (a group of villages) and assumed the title Maharana. Nagar Haveli was one of the Parganas, and its capital was Silvassa.

Why this record matters
The phrase “district of Dadra and Nagar Haveli and Daman and Diu and former union territory” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Sep 7, 2026. The linked authority identifier is Q46107. VIAF identifies the subject as 152106511. The Library of Congress control number is n81033273. Authority coordinates are 20.270, 73.020. 4 of 6 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank. The first chronological checks are 1783, 1954, 1961 and 2020.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
