Dadabhai Naoroji, a veteran nationalist and a prominent leader, served as Congress President three times. In his presidential address at the Calcutta session in 1906, he explicitly declared 'Swaraj' (self-rule) as the goal of the Indian National Congress, defining it as self-government like that of the United Kingdom or the colonies. His advocacy for Indian rights and self-government was consistent throughout his career, culminating in this formal declaration during the specified period.
