"From a scientific history perspective, the history of Dakshina Kannada starts at BC. 490 "
The Alupas ruled the erstwhile Dakshina Kannada region between the 8th and 14th century CE. Before 1860, Dakshina Kannada was part of a district called Kanara, which was under a single administration in the Madras Presidency. In 1860, the British split the area into South Kanara and North Kanara, the former being retained in the Madras Presidency, while the latter was made a part of Bombay Presidency in 1862.Kundapur taluk was earlier included in North Kanara but was later re-included in South Kanara.
During the Reorganisation of States in 1956, Kasaragod was split and transferred to the newly created Kerala state and Dakshina Kannada was transferred to Mysore state (present day Karnataka).
South Canara was a district under the British empire which included the present Dakshina Kannada, Udupi, Kasaragod districts and Aminidivi islands. Canara district was bifurcated in 1859 to form North Canara and South Canara. Dakshina Kannada became a district of Mysore State in 1956 which later was renamed Karnataka in 1973.
Kasaragod became a district of Kerala during the Re-organization of States and Aminidivi islands later became a part of Lakshadweep. The Udupi district was formed from the northern taluks of Dakshina Kannada in 1997. Later, the Karnataka Government, for the purpose of administration, split the greater Dakshina Kannada district into Udupi and present day Dakshina Kannada districts on 15 August 1997. Three taluks of the former district — Udupi, Karkala and Kundapura — formed the new Udupi district.
