The convergence of multiple socio-economic and political grievances created fertile ground for mass agitation.
- Rowlatt Act (Black Act): Passed in March 1919, it allowed detention of political prisoners without trial for two years, provoking widespread 'No Dalil, No Vakil, No Appeal'.
- Jallianwala Bagh Massacre: On April 13, 1919, General Reginald Dyer ordered indiscriminate firing on a peaceful unarmed crowd in Amritsar, killing hundreds.
- Khilafat Grievances: Indian Muslims were agitated over the harsh terms imposed on the Ottoman Caliph after World War I, leading to the Khilafat-Non-Cooperation alliance.
- Economic Distress: Post-war inflation, high taxation, scarcity of essential goods, and widespread unemployment alienated workers, peasants, and the middle class.
