Due to extreme hunger, Periyar felt compelled to enter one of the eateries disguised as a Brahmin with a sacred thread on his bare chest, but was betrayed by his moustache.
[20] After the intervention of Mahatma Gandhi, the agitation was given up and a compromise was reached with the Regent Sethu Lakshmi Bayi, who released all those arrested and opened the north, south, and west public roads leading to Vaikom Mahadeva Temple to all castes.
[37][38] Periyar and his followers campaigned constantly to influence and pressure the government to take measures to remove social inequality (abolish untouchability, manual scavenging system etc.)
[48] Immediately after his return, Periyar, in alliance with the enthusiastic communist, M. Singaravelar, began to work out a socio-political scheme incorporating socialist and self-respect ideals.
[47] In 1937, when Chakravarthi Rajagopalachari became the Chief Minister of Madras Presidency, he introduced Hindi as a compulsory language of study in schools, thereby igniting a series of anti-Hindi agitations.
[49] Tamil nationalists, the Justice Party under Sir A. T. Panneerselvam, and Periyar organised anti-Hindi protests in 1938 which ended with numerous arrests by the Rajaji government.
[56] In 1949, Periyar's chief lieutenant, Conjeevaram Natarajan Annadurai, established a separate association called the Dravida Munnetra Kazhagam (DMK), or Dravidian Progressive Federation.
[57] Periyar was convinced that individuals and movements that undertake the task of eradicating the social evils in the Indian sub-continent have to pursue the goal with devotion and dedication without deviating from the path and with uncompromising zeal.
The DMK advocated the thesis that the Tamil language was much richer than Sanskrit and Hindi in content, and thus was a key which opened the door to subjects to be learned.
[58] In 1956, despite warnings from P. Kakkan, the President of the Tamil Nadu Congress Committee, Periyar organised a procession to the Marina to burn pictures of the Hindu God Rama.
In his last meeting at Thiagaraya Nagar, Chennai on 19 December 1973, Periyar declared a call for action to gain social equality and a dignified way of life.
Periyar spent over fifty years giving speeches, propagating the realisation that everyone is an equal citizen and the differences on the basis of caste and creed were man-made to keep the innocent and ignorant as underdogs in the society.
He felt that they were trying to reassert their control over religion by using their superior caste status to claim the exclusive privilege to touch idols or enter the sanctum sanctorum.
[68] There have been hundreds of thousands of cases where wives have been murdered, mutilated, and burned alive because the father of the bride was unable to make the dowry payment to the husband.
[77] Periyar felt that a small number of cunning people created caste distinctions to dominate Indian society, so he emphasised that individuals must first develop self-respect and learn to analyse propositions rationally.
Ancient Tamil Nadu (part of Tamilakkam) had a different stratification of society in four or five regions (Tinai), determined by natural surroundings and adequate means of living.
[79] Periyar also argued that birds, animals, and worms, which are considered to be devoid of rationalism do not create castes, or differences of high and low in their own species.
"[89] Periyar's ideas on Tamil alphabet reforms included those such as the reasons for the vowel 'ஈ' (i) having a cursive and looped representation of the short form 'இ' (I).
Thus, the glory and excellence of a language and its script depend on how easily they can be understood or learned and on nothing else"[20] Periyar hailed the Thirukkural as a valuable scripture which contained many scientific and philosophical truths.
On the contrary, Periyar received sympathy and support from people such as Bhimrao Ramji Ambedkar and Muhammad Ali Jinnah for his views on the Congress, and for his opposition to Hindi.
[96] In 1955 Periyar threatened to burn the national flag, but on Chief Minister Kamaraj's pledge that Hindi should not be made compulsory, he postponed the action.
[100] Periyar, through the Justice Party, advocated against the imbalance of the domination of Brahmins who constituted only 3 percent[12][101] of the population, over government jobs, judiciary and the Madras University.
[103][104]Periyar also criticised Subramanya Bharathi in the journal Ticutar for portraying Mother Tamil as a sister of Sanskrit in his poems: "They say Bharati is an immortal poet ...
Periyar and his followers emphasised the difference in point of view between Gandhi and himself on the social issues, such as fighting the Untouchability Laws and eradication of the caste system.
As shown in the negotiations at Vaikom his methods for abolishing discrimination were: to stress on the orthodox, inhumane treatment of Untouchables; to secure voluntary lifting of the ban by changing the hearts of caste Hindus; and to work within a Hindu framework of ideas.
[118] On the Temple Entry issue, pro-Periyar sources claim that Gandhi never advocated the opening of Garbha Griha to Harijans in consequence of his Hindu belief.
"[120] On Hinduism, Periyar believed that it was a religion with no distinctive sacred book (Bhagawad Gita) or origins, but an imaginary faith preaching the "superiority" of the Brahmins, the inferiority of the Shudras, and the untouchability of the Dalits (Panchamas).
[130] In 2021, the Madurai Bench of the Madras High Court directed the state government to remove a false information from school and college syllabus that claimed that the UNESCO had conferred the title "Socrates of South-East Asia" on Periyar.
[131][132] In his letter to K. Kamaraj dated 5 November 1957, Jawaharlal Nehru expressed his displeasure against Periyar for his anti-Brahmin campaign, which called upon people to stab and kill Brahmins.
Soon after this, a camp was held at Periyar Mansion in Tiruchirapalli to train young men and women to spread the ideals of the Dravidar Kazhagam in rural areas.
