The Konkan (Konkani: कोंकण) is a stretch of land by the western coast of India, running from Daman at the mouth of Daman Ganga River in the north to Anjediva and Karwar in the south; with the Arabian Sea to the west and the Deccan plateau in the east.[verification needed] The hinterland east of the coast has numerous river valleys and riverine islands among the hilly slopes leading up into the tablelands of the Deccan. The region has been recognised by name, since at least the time of Strabo in the third century C.E., and was a thriving mercantile port with Arab tradesmen from the 10th century. The best-known islands of Konkan are Ilhas de Goa, the site of the Goa state's capital at Panjim, and the seven islands of Bombay, on which lies Mumbai, the capital of the state of Maharashtra.
Historically, the limits of Konkan have been flexible, and it has been known by additional names like "Aparanta" and "Gomanchal", the latter being defined as the coastal area between the Daman Ganga River in the north and the Gangavalli River in the south.
The ancient Sapta Konkan was a larger geographical area that extended from Gujarat to Kerala and included the whole region of coastal Maharashtra and coastal Karnataka. However, this segment overlaps the Konkan and Malabar coast continuum; and usually corresponds to the southernmost and northernmost stretches of these locales respectively.
According to the Sahyadrikhanda of the Skanda Purana, Parashurama threw his axe into the sea and commanded the Sea God to recede up to the point where his axe landed. The new piece of land thus recovered came to be known as Saptah-Konkana, meaning "piece of earth", "corner of earth", or "piece of corner", derived from Sanskrit words: koṇa (कोण, corner) + kaṇa (कण, piece). Xuanzang, the noted Chinese Buddhist monk, mentioned this region in his book as Konkana Desha; Varahamihira's Brihat-Samhita described Konkan as a region of India; and 15th century author Ratnakosh mentioned the word Konkandesha.
The Konkan extends throughout the western coasts of Maharashtra, Goa and Karnataka. It is bounded by the Western Ghats mountain range (also known as Sahyadri) in the east, the Arabian Sea in the west, the Daman Ganga River in the north and the River Aghanashini in the south. The Gangavalli flows in the district of Uttara Kannada in present-day Karnataka. Its northern bank constitutes the southernmost portion of Konkan. The towns of Karwar, Ankola, Kumta, Honavar and Bhatkal fall within the Konkan coast. The largest city on the Konkan coast is Mumbai, the state capital of Maharashtra. Districts on the Konkan coast are, from north to south:
