Daman, India in the context of Damaon, Diu

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.

The Konkan is a stretch of land by the western coast of India, bound by the river Daman Ganga at Damaon in the north, to Anjediva Island next to Karwar town in the south; with the Arabian Sea to the west and the Deccan Plateau to the east. The hinterland east of the coast has numerous river valleys, riverine islands and the hilly slopes known as the Western Ghats; that lead up into the tablelands of the Deccan. The Konkan region has been recognised by name, since at least the time of Strabo, in the third century CE. It had a thriving mercantile port with Arab tradesmen from the 10th century onwards. The best-known islands of Konkan are Ilhas de Goa, the site of the Goa state's capital at Panjim; also, the Seven Islands of Bombay, on which lies Mumbai, the capital of Maharashtra & the headquarters of Konkan Division.

The Portuguese conquered Goa when the governor Afonso de Albuquerque captured the city in 1510 from the Sultanate of Bijapur. Old Goa became the capital of Portuguese India, which included territories such as Fort Manuel of Cochin, Bom Bahia, Damaon, and Chaul. It was not among the places Albuquerque was supposed to conquer. He did so after he was offered the support and guidance of Timoji and his troops.

Albuquerque had been given orders by Manuel I of Portugal to capture Ormus, Aden, and Malacca only. Goa would remain under Portuguese control until 1961.

Daman district (English: /də'mɑːn/, Gujarati: [d̪əmən]) (formerly Distrito de Damão) is one of three districts of the Indian union territory of Dadra and Nagar Haveli and Daman and Diu. It is located on the west coast of India and is surrounded by the Valsad district of Gujarat to the north, east, and south; and by the Arabian Sea to the west. The district covers an area of 72 square kilometers (28 sq mi) and had a population of 191,173 as of the 2011 census, an increase of 69.256% from the 2001 census. The district headquarters is Daman. The territorial headquarters were previously in Panjim when it was jointly administered as Goa, Daman, and Diu until the time of the Konkani language agitation.

Daman lies at the mouth of the Daman Ganga River. The closest railway station is Vapi, which is 7 km away. Surat is to the north, and Mumbai is approximately 160 km (100 mi) to the south in the Konkan division of Maharashtra.

Bombay, also called Bom Bahia or Bom Baim in Indo-Portuguese creole, and Mumbai in the local language; is the financial and commercial capital of India and one of the most populous cities in the world. It's also the cosmopolitan city centre of the Greater Bombay Metropolitan Area, and the cultural base of the Bollywood film industry. At the time of the arrival of the Portuguese Armadas, Bombay was an archipelago of seven islands. Between the third century BCE and 1348, the islands came under the control of successive Hindu dynasties. The Delhi Sultanate had been ruling the area, along with Chaul, New Bombay, (Thana), and Damaon; with the local administration at Bassein (Vasai) since the raids of Malik Kafur in the Konkan region and across the Indian subcontinent. This territory in North Konkan, along with the Bombay islands were later taken over by the Sultan of Guzerat from 1391 to 1534, when he had declared the end of the his suzerainty to Delhi, after the Timurid invasion of it. Growing apprehensive of the power of the Moghal emperor Humayun, Sultan Bahadur Shah of Gujarat was obliged to sign the Treaty of Bassein on 23 December 1534; according to which, the Seven Islands of Bombay, Fort San Sebastian of Bassein in the strategic town of Bassein (Vasai), and its dependencies were offered to the Portuguese East Indies. The places were only later officially surrendered on 25 October 1535, by the Sultan of Guzerat.

The Portuguese in Goa-Anjediva and Bombay-Bassein were actively involved in the foundation and growth of their Latin Christian religion in Bombay and the neighbouring area. They called the island by various names, which finally took the written form Bom Baim, when the islands were leased to several Portuguese officers during their regime. Portuguese Franciscans and Jesuits built several churches in and around Bombay (Mumbai); the prominent ones are the St. Michael's Church at Mahim, St. John the Baptist Church at Andheri, St. Andrew's Church, the Basilica of Mount Bandra (Bombay) at Bandra, the Gloria Church at Byculla, & the Holy Spirit Church Nandakhal at Virar. The Portuguese also built several fortifications around the city, like the Bombay Castle, Castella de Aguada (Castelo da Aguada or Bandra Fort) and Madh Fort.
