Kannada Rajyotsava (Kannada: ಕನ್ನಡ ರಾಜ್ಯೋತ್ಸವ; Karnataka Formation Day; literally "Birth of the Karnataka state") is celebrated on 1 November every year. This was the day in 1956 when all the Kannada language-speaking regions of South India were merged to form the state of Karnataka.
The Rajyotsava day is listed as a government holiday in the state of Karnataka and is celebrated by Kannadigas across the world. It is marked by the announcement and presentation of the honours list for Rajyotsava Awards by the Government of Karnataka, hoisting of the unofficial Karnataka flag with an address from the Chief Minister and Governor of the state along with community festivals, orchestra, Kannada book releases and concerts.
Aluru Venkata Rao was the first person who dreamt of unifying the State as early as 1905 with the Karnataka Ekikarana movement. In 1950, India became republic and different provinces were formed in the country on the basis of language spoken in the particular region and this gave birth to the state of Mysore including various places in south India, which were earlier ruled by the kings.
