Foundation of Indian National Congress — Key Changes

N/A	1886	While not a constitutional amendment in the modern sense, the second session of the INC in Calcutta (1886) saw a significant expansion in delegate participation, with 436 delegates attending compared to 72 in the first session. This represented an 'amendment' to its initial scope, demonstrating its growing appeal and the increasing desire for broader representation from across India.	This expansion solidified the INC's claim as a truly national body, bringing together a wider array of regional leaders and diverse voices. It broadened the base of political discourse and strengthened the organization's legitimacy in articulating pan-Indian demands, moving beyond the initial, more limited gathering of the first session.
N/A	1887	The third session of the INC in Madras (1887) saw Badruddin Tyabji become the first Muslim president. This was a significant 'amendment' to the perceived secular and inclusive character of the Congress, actively countering early British attempts to portray it as a Hindu-dominated organization.	Tyabji's presidency reinforced the INC's commitment to national unity across religious lines. It sent a strong message against the nascent 'divide and rule' policies of the British and encouraged greater Muslim participation in the nationalist movement, strengthening the Congress's claim as a representative body for all Indians.
