K. S. Pandiarajan, a lawyer based in Madurai, started his political journey in the ultra-left movement during his student years, joining one of the many factions of the Communist Party of India (Marxist-Leninist) in the 1980s. He pursued a law degree with the aim of facilitating radical social change. However, his political career took a turn when he was overlooked for a leadership position within his party, allegedly due to his Brahmin heritage. This experience prompted him to reevaluate his political affiliations, as he believed that caste considerations were not as prevalent in the central leadership of the party, contrasting with the situation in Tamil Nadu. Originating from Tiruchendur, where his grandfather served as a temple priest, Pandiarajan's family faced financial challenges. His education in government institutions nurtured his passion for the Tamil language, leading him to initially believe that his commitment to social change would transcend caste barriers—a belief that ultimately proved misguided.
