The Kingdom of Mysore was a realm in the southern part of Deccan Plateau traditionally believed to have been founded in 1399 by two Hindu brothers, in the vicinity of the modern city of Mysore. From 1799 until 1950, it was a princely state, until 1947 in a subsidiary alliance with British India. The British took direct control over the princely state in 1831. Upon accession to the Dominion of India, it became Mysore State, later uniting with other Kannada speaking regions to form the state of Karnataka, with its ruler remaining as Rajapramukh until 1956, when he became the first governor of the reformed state.
