Annadurai and E. V. K. Sampath endeavoured to achieve their goals through parliamentary election processes. Sampath, who had earlier forfeited his seniority with Periyar's party to join DMK, saw the call for an independent Dravida Nadu was turning out to be an unrealistic goal. Sampath expressed concerns over using film stars to increase the popularity of the party. His views led him to cross swords with the major leaders of the party and eventually caused the first split in DMK. Sampath left DMK to begin his own party called the Tamil National Party.

Thus the Congress-led Central government became its major target for calls for reform. Immediately after Indian independence the Congress Party was popular throughout India and thus formed the government in many states including Madras Presidency. Even so, the Congress Party failed to obtain an absolute majority in the presidency in the state's first election. By the 1960s the popularity of the Congress party was in a steady decline. DMK leaders also perceived that the attempts to declare Hindi as the sole national language of India was an attempt impose an Aryan language unwilling people in the South. According to the terms of the Indian constitution dated 26 January 1965, English as an official language of India would come to an end and Hindi
