khilaft issue due to harsh Treaty of Severus which was a breach of promise to Muslims
Course
1919: Khilafat Committee of Md. Ali & Shaukat Ali demanded the revision of Treaty of Severus so dignity of Khalifa was maintained & Arabs were not to be under non muslims
requested MG to take leadership
1920: Khilafat Committee launched Khilafat Movement by giving a call for boycott of titles, civil services, army (Non cooperation) and non tax campaign (civil disobedience)
MG saw opportunity for Hindu-Muslim unity
∴ convinced INC to launch non cooperation mvmt (NCM)
convinced leaders like CR Das who otherwise wanted to use councils to oppose Brits (1919 Adjournment Motion)
Tilak stopped supporting religious goals & Bipin Chandra Pal resigned due to indifferences with MG
Besant, Jinnah also resigned as they opposed extra constitutional methods (NC, CDM)
