Key facts for exams

The freedom struggle is commonly divided into 4 phases: Early Resistance (1857-85), Early Nationalism (1885-1918), Mass Movements (1919-39), and the Final Push (1939-47).

The Indian National Congress, founded in 1885, became the principal vehicle of the movement for over six decades.

Mahatma Gandhi led three major nationwide movements: Non-Cooperation (1920), Civil Disobedience (1930), and Quit India (1942).

India became independent on 15 August 1947 under the Indian Independence Act, simultaneously partitioned into India and Pakistan.

The four phases

Early Resistance (1857-1885) covers the Revolt of 1857 through the founding of the Congress. Early Nationalism (1885-1918) spans the Partition of Bengal, the Moderate-Extremist split, and Gandhi's first satyagraha. Mass Movements (1919-1939) covers Jallianwala Bagh through the Government of India Act 1935 — the era of Non-Cooperation, Civil Disobedience, and the Poona Pact. The Final Push (1939-1947) covers World War II's impact, Quit India, the INA, and Partition.
