The foundation day of any state is the day that celebrates the formation of the state. The southern state of Karnataka celebrates its foundation/formation day on November 1. Notably, the day also coincides with the formation of several other states such as Kerala, Punjab, Haryana, Madhya Pradesh, Chhattisgarh and Rajasthan.
In Karnataka, the foundation day is called Karnataka Rajyotsava Day, and the state’s official red and yellow flags adorn the streets, houses and official buildings to celebrate the foundation of the state. The day also marks the annual presentation of the Rajyotsava Awards which is the second-highest civilian honour in the state.
Instituted in 1966, the awards are given to people in the fields of agriculture, environment, education, journalism, judiciary, literature, medicine, music, sports, social service among others. This year, 66 eminent personalities will be conferred with award.
The Karnataka Ekikarana movement was started by Aluru Venkata Rao back in 1905 and culminated with the Mysore State, which included the erstwhile princely state of Mysore, that resulted after merging the Kannada-speaking areas of Bombay and Madras presidencies as well as the principality of Hyderabad to create a unified Kannada-speaking state on November 1, 1956.
