Mangalore derives its name from the local Hindu deity Mangaladevi. It developed as a port on the Arabian Sea – remaining, to this day, a major port of India. The city was a source of contention between the British and the Mysore rulers, Hyder Ali and Tippu Sultan. Mangalore is demographically diverse with several languages, including Tulu, Konkani, Kannada, and Beary commonly spoken and understood. Mangalore lies on the backwaters of the Netravati and Gurupura rivers
