The agitations started on 11 March 2013 when eight students of Loyola College, Chennai, who fasted in condemnation of alleged atrocities committed on Tamils in Sri Lanka were arrested by the Tamil Nadu police. The arrest was criticised by student organisations as well as the Loyola College management and nine colleges across the city went on strike. The following protests see students from all over Tamil Nadu take into streets, it was a massive outrage of Tamil Nadu people and students against sinhala government after 1983 anti-Tamil pogrom. From school to colleges a mass number of students participated in the protest. Students from other states lik who are studying in Tamil Nadu colleges too participated. Numerous protests, rallies held in marina beach which saw huge number of students. The anger and anguish of students turned against DMK and Congress which is the ruling party during 2009 Eelam war. A statewide general strike declared on 12 March 2013 by the Tamil Eelam Supporters Organisation evoked a mixed response with most of the political parties in the state keeping aloof alleging inaction on the part of the main participant Dravida Munnetra Kazhagam which was in power during the decisive stages of Eelam War IV. Student organisations called for statewide agitations on Monday, 18 March, forcing arts and science colleges in the state to close down for an indefinite period.

As protests peaked in Tamil Nadu national and international media provided good coverage. One remarkable effect of this protest is DMK chief Karuna fearing students outrage pulled out of congress alliance, On 19 March DMK chief announced withdrawal from UPA alliance citing Congress disregard to the suffering of Eelam Tamil. When DMK pulled out of UPA it was well received by DMK supporters. Congress was isolated in Tamil Nadu in 2014 general elections it contested in 40 seats alone and lost in all constituencies. But ironically DMK formed alliance with congress again in May 2016 Tamil Nadu state elections showing its own colors.
