In the early 20th century, Mahatma Gandhi initiated critical movements that crystallized the Indian National Movement into a mass struggle for independence. This section details three pivotal movements: the Champaran Satyagraha in 1917, which addressed the grievances of indigo farmers in Bihar; the Ahmedabad Mill Strike in 1918, focusing on demands of textile workers facing unfair wage practices; and the Kheda Satyagraha in 1918, advocating for peasants suffering due to famine and poor harvests. These movements exemplified Gandhi's principles of non-violent resistance and mobilized a diverse demographic of Indian society in the fight for Swaraj (self-rule). Each movement showcased a concerted effort to challenge injustice and empower the oppressed, laying the foundation for later, broader movements.
