Karnataka (; ISO: Karnāṭaka, Kannada pronunciation: [kɐˈɾnäːʈɐkɐ], also known as Karunāḍu) is a state in the southwestern region of India. It was formed on 1 November 1956, with the passage of the States Reorganisation Act. Originally known as the State of Mysore , it was renamed Karnataka in 1973. The state corresponds to the Carnatic region. Its capital and largest city is Bangalore. Karnataka is bordered by the Arabian Sea to the west, Goa to the northwest, Maharashtra to the north, Telangana to the northeast, Andhra Pradesh to the east, Tamil Nadu to the southeast, and Kerala to the southwest. It is the only southern state to have land borders with all of the other four southern Indian sister states. The state covers an area of 191,791 square kilometres (74,051 sq mi), or 5.83 percent of the total geographical area of India. It is the sixth-largest Indian state by area. With 61,130,704 inhabitants at the 2011 census, Karnataka is the eighth-largest state by population, comprising 31 districts. Kannada, one of the classical languages of India, is the most widely spoken and official language of the state. Other minority languages spoken include Urdu, Konkani, Marathi, Tulu, Tamil, Telugu, Malayalam, Kodava and Beary. Karnataka also contains some of the only villages in India where Sanskrit is primarily spoken.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. The economy of Karnataka is the sixth-largest of any Indian state with ₹16.65 trillion (US$210 billion) in gross domestic product and a per capita GDP of ₹226,000 (US$2,800). Karnataka has the nineteenth-highest ranking among Indian states in Human Development Index.

The Vijayanagara Empire, also called the Karnata Kingdom, was based in the Deccan Plateau region of South India, which consisted the modern states of Karnataka, Andhra Pradesh, Tamilnadu, Kerala, Goa and some parts of Telangana and Maharashtra. It was established in 1336 by the brothers Harihara I and Bukka Raya I of the Sangama dynasty, members of a pastoralist cowherd community that claimed Yadava lineage. The empire rose to prominence as a culmination of attempts by the southern powers to ward off Perso-Turkic Islamic invasions by the end of the 13th century. At its peak, it subjugated almost all of South India's ruling families and pushed the sultans of the Deccan beyond the Tungabhadra-Krishna river doab region, in addition to annexing modern day Odisha (ancient Kalinga) from the Gajapati Kingdom thus becoming a notable power. It lasted until 1646, although its power declined after a major military defeat in the Battle of Talikota in 1565 by the combined armies of the Deccan sultanates. The empire is named after its capital city of Vijayanagara, whose ruins surround present day Hampi, now a World Heritage Site in Karnataka, India. The wealth and fame of the empire inspired visits by and writings of medieval European travelers such as Domingo Paes, Fernão Nunes, and Niccolò de' Conti. These travelogues, contemporary literature and epigraphy in the local languages and modern archeological excavations at Vijayanagara has provided ample information about the history and power of the empire. The empire's legacy includes monuments spread over South India, the best known of which is the group at Hampi. Different temple building traditions in South and Central India were merged into the Vijayanagara architecture style. This synthesis inspired architectural innovations in the construction of Hindu temples. Efficient administration and vigorous overseas trade brought new technologies to the region such as water management systems for irrigation. The empire's patronage enabled fine arts and literature to reach new heights in Kannada, Telugu, Tamil, and Sanskrit with topics such as astronomy, mathematics, medicine, fiction, musicology, historiography and theater gaining popularity. The classical music of Southern India, Carnatic music, evolved into its current form. The Vijayanagara Empire created an epoch in the history of Southern India that transcended regionalism by promoting Hinduism as a unifying factor.
