The Justice Party, officially the South Indian Liberal Federation, was a political party in the Madras Presidency of British India. It was established on 20 November 1916 in Victoria Public Hall in Madras by Dr C. Natesa Mudaliar and co-founded by T. M. Nair, P. Theagaraya Chetty and Alamelu Mangai Thayarammal as a result of a series of non-Brahmin conferences and meetings in the presidency. Communal division between Brahmins and non-Brahmins began in the presidency during the late-19th and early-20th century, mainly due to caste prejudices and disproportionate Brahminical representation in government jobs. The Justice Party's foundation marked the culmination of several efforts to establish an organisation to represent the non-Brahmins in Madras and is seen as the start of the Dravidian Movement.
During its early years, the party was involved in petitioning the imperial administrative bodies and British colonial officials demanding more representation for non-Brahmins in government. When a diarchial system of administration was established due to the 1919 Montagu–Chelmsford reforms, the Justice Party took part in presidential governance. In 1920, it won the first direct elections in the presidency and formed the government. For the next seventeen years, it formed four out of the five ministries and was in power for thirteen years. It was the main political alternative to the nationalist Indian National Congress in Madras. After it lost to the Congress in the 1937 election, it never recovered. It came under the leadership of Periyar E. V. Ramaswamy and his Self-Respect Movement. In 1944, Periyar transformed the Justice Party into the social organisation Dravidar Kazhagam and withdrew it from electoral politics. A rebel faction that called itself the original Justice Party, survived to contest one final election, in 1952.

The Justice Party was isolated in contemporary Indian politics by its many controversial activities. It opposed Brahmins in civil service and politics, and this anti-Brahmin attitude shaped many of its ideas and policies. It opposed Annie Besant and her Home rule movement, because it believed home rule would benefit the Brahmins. The party also campaigned against the non-cooperation movement in the presidency. It was at odds with Mahatma Gandhi, due to his opposition towards creation of separate Dravidian country. Its mistrust of the "Brahmin–dominated" Congress led it to adopt a hostile stance toward the Indian independence movement. The Justice Party's period in power is remembered for the introduction of caste-based reservations, and educational and religious reform. In opposition it is remembered for participating in the anti-Hindi agitations of 1937–40. The party had a role in creation of Andhra and Annamalai universities and for developing the area around present-day Theagaroya Nagar in Madras city. The Justice Party and the Dravidar Kazhagam are the ideological predecessors of present-day Dravidian parties like the Dravida Munnetra Kazhagam and the All-India Anna Dravida Munnetra Kazhagam, which have ruled Tamil Nadu (one of the successor states to Madras Presidency) continuously since 1967.

Background
Brahmin/non-Brahmin divide
The Brahmins in Madras Presidency enjoyed a higher position in India's social hierarchy. By the 1850s, Telugu and Tamil Brahmins comprising only 3.2% of the population began to increase their political power by filling most of the jobs which were open to Indian men at that time. They dominated the administrative services and the newly created urban professions in the 19th and early 20th century. The higher literacy and English language proficiency among Brahmins were instrumental in this ascendancy. The political, social, and economical divide between Brahmins and non-Brahmins became more apparent in the beginning of the 20th century. This breach was further exaggerated by Annie Besant and her Home Rule for India movement. The following table shows the distribution of selected jobs among different caste groups in 1912 in Madras Presidency.
