[2] Kamaraj was instrumental in the ascension and downfall of the first six Chief Ministers of Tamil Nadu following independence: T. Prakasam, O.P.

Kamaraj originally threw his support behind T. Prakasam to prevent C. Rajagopalachari from becoming Chief Minister in 1946, however, Kamaraj felt it was too difficult to control Prakasam as he was Telugu and didn't feel the need to report to the Tamil Nadu Congress Committee.

[2] The general election of 1952 temporarily reduced the Congress Party to a minority in the state legislative assembly.

[3] Per the Constitution, the President sought the advice of the Prime Minister, Jawaharlal Nehru, who was unable to make a decision on the matter.

[3] As Rajagopalachari would not seek election to the lower house of the state legislature, the interim Chief Minister, Kumaraswamy Raja, promptly recommended Rajagopalachari's appointment to the upper house of the state legislature, and the new governor, Sri Prakasa, swiftly accepted the recommendation.

Rajagopalachari proved a majority more than three months later by convincing opposition members to defect, and allying himself with parties that had not joined the UDF.

[3] Kamaraj increased his stronghold over Tamil Nadu politics following the separation of the Telugu-speaking areas from Tamil Nadu in 1953, and facilitated the removal of Rajagopalachari as Chief Minister in 1954 after Rajagopalachari's implementation of the unpopular Modified Scheme of Elementary Education.

As Chief Minister, Kamaraj paid special attention to education as that was the issue that led to his predecessor's downfall.

[4] At the same time, secondary education was restructured—mathematics, science, and social studies were made compulsory subjects, and students were provided the opportunity to learn their language of choice as well as Hindi and English.

Nine large-scale irrigation projects reaching about 3,34,000 acres were completed by the state government during the first five-year plan (1951–1956) for a total cost of about 29,00,00,000 rupees.

M. Bhakthavatsalam succeeded Kamaraj and would remain Chief Minister until the election of 1967, when power shifted to the Dravida Munnetra Kazhagam.

DK was a non-political party which demanded the establishment of an independent state called Dravida Nadu.

They differed in very few but were identical in important topics, such as eradication of casteism, promoting religious equality and extermination of untouchability.

[citation needed] After the death of Velupillai Prabhakaran, a revival, even though not a big enough to create an impact in political balance, is seen.

[7] Whichever party was in the rule, made sure that all the households have a television set, the womenfolk have access to work on the economy of their family by providing them household appliances[8] and the students have all the necessary tools to reach and complete their education namely bicycle, textbooks, stationery and laptops.

[9] At the same time, the promise of and distribution of freebies is considered and criticized to be a form of bribery, disguised as people welfare.

[10] The leftists and the left leaning parties have raised concerns about the revenue model used for financing the freebie schemes.

They accuse the two parties of depoliticizing the electorate and bribing the voters to turn blind eye to the corruptions of the regimes[11][12][13] These social welfare schemes provide the Dravidian faction of the Tamil Nadu politics an edge over the other regional and national parties.

[18] In 2001, the sitting DMK government came up with a huge alliance with caste parties and was defeated in 2001 assembly election.

Still caste based political parties are part of both the ruling and opposition alliances in all the successive elections.

Rajinikanth who is enjoying a popular status in Tamil Nadu was in the race to start a political party in 2020, later reverted the decision due to health issues during covid pandemic.

The worship of party leader by members is widely spread in Tamil Nadu, sometimes it reaches a fanatical level.
