The Gandhi-Irwin Pact took place in 1931, since it suspended civil disobedience and enabled Congress participation in the Second Round Table Conference. On the Gandhi-Irwin Pact: it was signed by Mahatma Gandhi and Viceroy Lord Irwin, and in return for Congress's participation in the Second Round Table Conference, the government agreed to release political prisoners who were not convicted of violence. The Gandhi-Irwin Pact belongs to the 1927-1947 phase of India's national movement, and exam setters often pair the Gandhi-Irwin Pact with neighbouring milestones on this timeline to test precise, date-wise recall. 1928 is incorrect because the Gandhi-Irwin Pact is dated to 1931, not 1928. 1940 is incorrect because the Gandhi-Irwin Pact is dated to 1931, not 1940. 1945 is incorrect because the Gandhi-Irwin Pact is dated to 1931, not 1945. Competitive exams such as SSC CGL, SSC CHSL, State PSC, and Railway exams frequently test the Gandhi-Irwin Pact of 1931, so keeping the year, the key person, and the outcome linked together in memory helps avoid confusion with nearby events in the national movement timeline. Candidates preparing for the Gandhi-Irwin Pact question should also revise the events immediately before and after it on the 1927-1947 timeline, since paper-setters frequently frame options using adjacent years and closely related personalities. Remember: Gandhi-Irwin Pact — 1931 — Mahatma Gandhi and Lord Irwin.
