In which of the following movements was the slogan-'Vadakku Vaazhkiradhu; Therkku Thaeikiradhu' (The north thrives even as the south decays)- used?

Dravidian movement

The correct answer is Option (4) → Dravidian movement

Dravidian movement: ‘Vadakku Vaazhgiradhu; Therkku Thaeikiradhu’ [The north thrives even as the south decays]. This popular slogan sums up the dominant sentiments of one of India’s most effective regional movements, the Dravidian movement, at one point of time. This was one of the first regional movements in Indian politics. Though some sections of this movement had ambitions of creating a Dravida nation, the movement did not take to arms. It used democratic means like public debates and the electoral platform to achieve its ends. This strategy paid off as the movement acquired political power in the State and also became influential at the national level.
