Mumbai, formerly known as Bombay, is the capital of the Indian state of Maharashtra and is the most populous Indian city. Mumbai is located on an island off the west coast of India. It forms one of the world's most populous conurbations. The city, which has a deep natural harbour, is also the largest port in western India, handling over half of India's passenger traffic.
Mumbai is the commercial capital of India, and houses important financial institutions such as the Reserve Bank of India, the Bombay Stock Exchange, and the corporate headquarters of many Indian companies. Owing to the immense business opportunities available in Mumbai and the relatively high standard of living, it has attracted migrants from all over India and South Asia, making the city a potpourri of various communities and cultures. Within Mumbai is located Bollywood, the epicentre of the country's Hindi film and television industry, producing the world's highest number of films annually. Mumbai is also one of the rare cities to accommodate a National Park within its municipal limits.
The appellation Mumbai is an eponym, etymologically derived from Mumba - the name of the local Hindu goddess Mumbadevi, and Aai - meaning mother in Marathi. In the 16th century, the Portuguese named the area Bom Bahia, which means Good Bay. This was later corrupted to Bomaím or Bombaim, by which name it is still known in Portuguese; and after the British gained possession, it was anglicised to Bombay. The name was officially changed from Bombay to Mumbai in 1995, but the former name is still popularly used in the West and by many of the city's inhabitants and famous institutions.
