Karnataka is a state in the southwestern region of India. It was formed as Mysore State on 1 November 1956, with the passage of the States Reorganisation Act, and renamed Karnataka in 1973. The state is bordered by the Lakshadweep 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. With 61,130,704 inhabitants at the 2011 census, Karnataka is the eighth-largest state by population, comprising 31 districts. With 15,257,000 residents, the state capital Bengaluru is the largest city of Karnataka.

The economy of Karnataka is among the most productive in the country with a gross state domestic product (GSDP) of ₹25.01 trillion (US$300 billion) and a per capita GSDP of ₹332,926 (US$3,900) for the financial year 2023–24. The state experienced a GSDP growth of 10.2% for the same fiscal year. After Bengaluru Urban, Dakshina Kannada, Hubli–Dharwad, and Belagavi districts contribute the highest revenue to the state respectively. The capital of the state, Bengaluru, is known as the Silicon Valley of India, for its immense contributions to the country's information technology sector. A total of 1,973 companies in the state were found to have been involved in the IT sector as of 2007.

Mangaluru (Kannada: [mɐŋɡɐɭuːru]), formerly called Mangalore (/ˈmæŋɡəlɔːr, ˌmæŋɡəˈlɔːr/ MANG-gə-lor, -⁠LOR), is a major industrial port city in the Indian state of Karnataka and on the west coast of India. It is located between the Arabian Sea and the Western Ghats about 352 km (219 mi) west of Bengaluru, the state capital, 14 km (8+1⁄2 mi) north of the Karnataka–Kerala border and 297 km (185 mi) south of Goa. Mangaluru is the state's only city to have all four modes of transport—air, road, rail and sea. The population of the urban agglomeration was 619,664 according to the 2011 national census of India. It is known for being one of the locations of the Indian strategic petroleum reserves.

The city developed as a port in the Laccadive Sea during ancient times, and after Independence a new port was constructed in 1968 and has since become a major port of India that handles 75 percent of India's coffee and cashew exports. It is also the country's seventh largest container port. Mangaluru has been ruled by several major powers, including the Mauryan empire, Kadambas, Alupas, Vijayanagara Empire, and Keladi Nayaks. In 1568 Jain Tuluva Queen Abbakka Chowta killed Portuguese officers General Jao Peixoto and Admiral Mascarenhas in Battle in Ullal. The city was a source of contention between the British and the Kingdom of Mysore rulers Hyder Ali and Tipu Sultan, and was eventually annexed by the British in 1799. Mangaluru remained part of the Madras Presidency until India's independence in 1947 and was unified with Mysore State (now called Karnataka) in 1956.

The Maharaja of Mysore was the king and principal ruler of the Kingdom of Mysore and briefly of Mysore State in the Indian Dominion roughly between the mid- to late-1300s and 1950. The Maharaja's consort was called the Maharani of Mysore.

In title, the role has been known by different names over time, from poleygar (Kannada, pāLegāra, for 'chieftain') during the early days of the fiefdom to raja (Sanskrit and Kannada, king–of especially a small region) during its early days as a kingdom to Maharaja (Sanskrit and Kannada, [great] king–of a formidable kingdom) for the rest of its period. In terms of succession, the successor was either a hereditary inheritor or, in case of no issue, handpicked by the reigning monarch or his privy council. All rulers under the Sanskrit-Kannada titles of raja or maharaja were exclusively from the house of Wadiyar.

Hyderabad State was a state in the Dominion and later Republic of India, formed after the accession of the State of Hyderabad into the Union on 17 September 1948. It existed from 1948 to 1956. Hyderabad State comprised present day Telangana, Marathwada, and Hyderabad-Karnataka.

Following the States Reorganisation Act, which implemented a linguistic reorganisation of states, the Hyderabad state was dissolved. Its different regions were merged with Andhra State, Mysore State and Bombay State respectively.

Coorg State was a Part-C state in India which existed from 1950 to 1956. When the Constitution of India came into force on 26 January 1950, most of the existing provinces were reconstituted into states. Thus, Coorg Province became Coorg State. Coorg State was ruled by a Chief Commissioner with Mercara as its capital. The head of the government was the Chief Minister. Coorg State was abolished on 1 November 1956 as per the States Reorganisation Act, 1956 and its territory was merged with Mysore State (later renamed as Karnataka in 1973). Currently, Coorg forms a district of Karnataka state.

The Unification of Karnataka or Karnataka Ekikarana refers to the formation of the Indian state of Karnataka (then named Mysore State) in 1956 when several Indian states were created by redrawing borders based on linguistic demographics. Decades earlier during British rule, the demand for a state based on Kannada demographics had been made.
