Answer
Radicalism, espoused by Lala Lajpat Rai, aimed to challenge British colonial rule in India through assertive and militant methods. Unlike the moderate faction seeking gradual constitutional reforms, Rai advocated for direct confrontation, mass mobilization, and the use of force if necessary. His radical stance sought to accelerate the pace of India's independence and galvanize the masses toward a more confrontational approach against the oppressive colonial power.
