Kerala Day or Kerala Piravi is celebrated to commemorate the birth of Kerala as an independent State in the Republic of India on November 1, 1956.
Prior to this unification, Kerala was divided into three independent provinces of Malabar, Cochin, and Travancore. Malabar Presidency constituted the northernmost territories of Kerala that included Thalassery, Kannur, and Kasaragod. The princely State of Cochin occupied the middle section, and the sovereign State of Travancore administered the southern region. After the Independence of India, there arose a strong need to carve new states on a linguistic basis. Thus, a few years after Independence, Kerala was reorganized as one such independent State.
Kerala Piravi Day commemorates this momentous union that led to the formation of modern-day Kerala as we know it.
