Chengalaraya Reddy Formation 25 October 1947 The Chief Minister of Karnataka is the chief executive of the south Indian state of Karnataka. As per the Constitution of India, the governor is a state 's de jure head, but de facto executive authority rests with the chief minister. Following elections to the Karnataka Legislative Assembly, the state 's governor usually invites the party ( or coalition ) with a majority of seats to form the government. The governor appoints the chief minister, whose council of ministers are collectively responsible to the assembly. Given that he has the confidence of the assembly, the chief minister 's term is for five years and is subject to no term limits. Since 1947, twenty - two people have been Chief Minister of Mysore ( as the state was known before 1 November 1973 ) and Karnataka. A majority of them belonged to the Indian National Congress party, including inaugural office - holder K. Chengalaraya Reddy. The longest - serving chief minister, D. Devaraj Urs, held the office for over seven years in the 1970s. The Janata Party 's Ramakrishna Hegde has the second - longest tenure, while the Congress 's Veerendra Patil had the largest gap between two terms ( over eighteen years ). One chief minister, H.D. Deve Gowda, went on to become the eleventh Prime Minister of India, while another, B.D. Jatti, served as the country 's fifth Vice President. There have been six instances of President 's rule in Karnataka, most recently in 2007 -- 08. The incumbent chief minister is the Janata Dal ( Secular ) 's H.D.

Footnotes Wikimedia Commons has media related to Chief ministers of Karnataka. Jump up ^ A parenthetical number indicates that the incumbent has previously held office. Jump up ^ This column only names the chief minister 's party. The state government he headed may have been a complex coalition of several parties and independents ; these are not listed here. Jump up ^ Mysore State came into being in August 1947 when Maharaja Jayachamarajendra Wodeyar signed the Instrument of Accession to merge the Princely State of Mysore with the Dominion of India. Jump up ^ On 1 November 1956, via the States Reorganisation Act, Mysore State was significantly expanded along linguistic lines. The Kannada - speaking districts of Bombay, Hyderabad and Madras states, as well as the entirety of Coorg, were added to it. ^ Jump up to : President 's rule may be imposed when the `` government in a state is not able to function as per the Constitution '', which often happens because no party or coalition has a majority in the assembly. When President 's rule is in force in a state, its council of ministers stands dissolved. The office of chief minister thus lies vacant, and the administration is taken over by the governor, who functions on behalf of the central government. At times, the legislative assembly also stands dissolved. Jump up ^ On 1 November 1973, via the Mysore State ( Alteration of Name ) Act, Mysore State was renamed as Karnataka. Thus, Devaraj Urs was Chief Minister of Mysore between 20 March 1972 and 31 October 1973, and Chief Minister of Karnataka after that. Jump up ^ In mid-1979 Urs split from the Indira Gandhi - led Congress ( I ), and served the remainder of his term as a Indian National Congress ( Urs ) member. Jump up ^ According to Frontline magazine, `` Following the poor performance of the Janata Party in the 1984 ( general ) elections ( it won only four out of the 28 seats ), Hegde resigned on the grounds that his party had lost its popular mandate. Prime Minister Rajiv Gandhi allowed him to head a caretaker government. In the 1985 ( assembly ) elections the Janata Party came to power with a comfortable majority. '' Jump up ^ According to Frontline, Hegde resigned `` in February 1986 when the Karnataka High Court censured his government for the way it handled arrack bottling contracts ''. He withdrew his resignation after a couple of days, `` following pressure from his party legislators ''. References Jump up ^ Durga Das Basu.
