Let us look at the timeline of the major events in the Indian National Movement:
- Champaran Satyagraha (1917): Gandhi's first civil disobedience movement.
- Jallianwala Bagh Massacre (1919): A brutal incident in Amritsar led by General Dyer.
- Peasant Movement in Bardoli (1928): Led by Sardar Vallabhbhai Patel in Gujarat.
- Second Round Table Conference (1931): Attended by Mahatma Gandhi in London.
Thus, the correct chronological order is: Champaran Satyagraha → Jallianwala Bagh Massacre → Bardoli Movement → Second Round Table Conference.
