India, officially the Republic of India, is a country in South Asia. It is the seventh-largest country by area; the most populous country since 2023; and, since its independence in 1947, the world's most populous democracy. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is near Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia.

Dadra is one of the two talukas in Dadra and Nagar Haveli district, India. It is an enclave lying a few kilometres north west of Nagar Haveli and is surrounded by Gujarat.

Among the states and union territories of India, a Union Territory (UT) is a region that is directly governed by the central government of India, as opposed to the states, which have their own state government systems. Unlike states, Union Territories do not have their own full-fledged government but are administered by a Lieutenant governor or Administrator appointed by the President of India.

Dadra and Nagar Haveli 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.
