The two main river systems of the state are the Krishna and its tributaries, the Bhima , Ghataprabha , Vedavathi , Malaprabha , and Tungabhadra , in the north, and the Kaveri and its tributaries, the Hemavati , Shimsha , Arkavati , Lakshmana Thirtha and Kabini , in the south. Most of these rivers flow out of Karnataka eastward, reaching the sea at the Bay of Bengal.
Though several etymologies have been suggested for the name Karnataka, the generally accepted one is that Karnataka is derived from the Kannada words karu and nādu , meaning "elevated land". Karu nadu may also be read as karu , meaning "black", and nadu , meaning "region", as a reference to the black cotton soil found in the Bayalu Seeme region of the state. The British used the word Carnatic , sometimes Karnatak , to describe both sides of peninsular India, south of the Krishna. 
With an antiquity that dates to the paleolithic , Karnataka has been home to some of the most powerful empires of ancient and medieval India. The philosophers and musical bards patronised by these empires launched socio-religious and literary movements which have endured to the present day. Karnataka has contributed significantly to both forms of Indian classical music, the Carnatic and Hindustani traditions.
