The First World War significantly influenced India's freedom struggle, leading to increased discontent against British rule due to economic hardships and oppressive measures like the Rowlatt Act. Mahatma Gandhi's philosophy of Satyagraha emphasized non-violence and truth in opposition to injustice, sparking various movements including the 1919 Jallianwala Bagh massacre and the Non-Cooperation Movement. Ultimately, these collective struggles fostered a sense of nationalism and unity among diverse Indian communities, setting the stage for future demands for independence.
