Key topic 3 · Key developments, 1927–39

What a Grade 9 answer knows here. 1937 is the year the two-nation argument acquired evidence. Congress governed alone because it had won, which was constitutionally correct and politically fatal: it let Jinnah say that a Hindu majority would rule and would not share, and unlike in 1930 he could now point at something.

Every lesson here ends the same way: learn it, teach it to an AI pupil who asks the awkward question, then defend it against the thinker with the strongest claim on it — free · no account needed.

The 3 lessons

The Simon Commission

How did a routine statutory review unite the two organisations nothing else could unite? The Government of India Act of 1919 required a statutory commission after ten years to report on how far responsible government had progressed.

The dates that earn marks in this key topic

Two from each lesson, in the order the topic is taught — each with the reason it is worth a mark, and the lesson that places it.

November 1927 — The Simon Commission appointed with seven British members and no Indian.: The composition is the whole cause of what follows and can be stated in eight words. (The Simon Commission)
February 1928 — The Commission arrives to black flags and Simon Go Back.: The first nationwide agitation since 1922 and the first to unite Congress and the League. (The Simon Commission)
12 March – 5 April 1930 — The march from Sabarmati to Dandi: 241 miles in 24 days with 78 initial marchers.: The duration was the design. A short march is an event; a long one is a daily news story. (The Salt March and civil disobedience)
6 April 1930 — Gandhi picks up salt at Dandi.: The moment of illegality, and the date to quote precisely. (The Salt March and civil disobedience)
August 1935 — The Government of India Act: provincial autonomy granted; the federal centre never comes into being.: The two halves of the Act had completely different fates and an answer must separate them. (The Government of India Act (1935) and the 1937 elections)
February 1937 — Congress wins 8 of 11 provinces; the League takes under 5 per cent of the Muslim vote.: The League's catastrophe is the fact that makes 1946 astonishing and requires explanation. (The Government of India Act (1935) and the 1937 elections)

The people to place

John Simon — Liberal MP and chairman; his report in 1930 recommended provincial autonomy and was overtaken by events. (The Simon Commission)
Lala Lajpat Rai — Veteran Congress leader injured in a lathi charge at Lahore in 1928 and dead three weeks later. (The Simon Commission)
Motilal Nehru — Chaired the all-parties committee that produced the Nehru Report. (The Simon Commission)
Muhammad Ali Jinnah — Led the League into the boycott, then broke with the Nehru Report and issued the Fourteen Points. (The Simon Commission)
Mohandas Gandhi — Chose salt, walked to Dandi, and negotiated the 1931 Pact. (The Salt March and civil disobedience)
Lord Irwin — Viceroy who negotiated with Gandhi as an equal in 1931. (The Salt March and civil disobedience)
Sarojini Naidu — Led the Dharasana raid after Gandhi's arrest; the campaign's most prominent woman leader. (The Salt March and civil disobedience)
Abdul Ghaffar Khan — Led the Khudai Khidmatgar in the North-West Frontier, a Muslim non-violent mass movement. (The Salt March and civil disobedience)
Jawaharlal Nehru — Congress president in 1936 and 1937; associated with the refusal of coalition and with the claim that there were only two forces in India, Congress and the British. (The Government of India Act (1935) and the 1937 elections)
Sikandar Hayat Khan — Unionist premier of Punjab; his cross-communal party governed the province the League claimed to speak for. (The Government of India Act (1935) and the 1937 elections)
A. K. Fazlul Huq — Krishak Praja Party premier of Bengal; moved the Lahore Resolution in 1940. (The Government of India Act (1935) and the 1937 elections)

What students say — and what is actually the case

“The Simon Commission was set up to deny Indians a say.” — It was a statutory requirement of the 1919 Act, brought forward for British party reasons. The exclusion of Indians was a decision about the form of a parliamentary commission — which is exactly why it was so damaging: nobody in London thought it needed justifying. (The Simon Commission)
“The Salt March forced the British to abolish the salt tax.” — The tax survived until 1946. The march's achievement was international attention, mass participation and the negotiation of 1931, not the repeal of the law it broke. (The Salt March and civil disobedience)
“The 1935 Act gave India a federal government.” — The federal half never came into force because too few princes acceded. The centre remained under the 1919 arrangements with a Viceroy. Only the provincial half operated. (The Government of India Act (1935) and the 1937 elections)
