📖 ~14 min read 🏛️ Modern Indian History

Introduction

The demand for a separate Muslim homeland grew steadily from the early 20th century, culminating in the Partition of India in August 1947 — one of the largest and most traumatic mass migrations in human history, accompanying the birth of two independent nations.

Growth of Communal Politics

MilestoneYearSignificance
All India Muslim League founded1906, DhakaFormed to safeguard Muslim political interests; initially loyalist towards the British
Morley-Minto Reforms1909Introduced separate electorates for Muslims — institutionalised communal representation

↓
Interim Government formed (September 1946), but with League-Congress friction

Radcliffe Line

The actual boundary between India and Pakistan (in Punjab and Bengal) was drawn by a British lawyer, Sir Cyril Radcliffe, who had never previously visited India — the line's announcement (just after Independence) triggered massive, often violent, cross-border migration.

Consequences of Partition

  • One of history's largest mass migrations — an estimated 10-15 million people displaced across the new borders.
  • Widespread communal violence, with estimates of deaths ranging from several hundred thousand to over a million.
  • Long-term geopolitical consequences — ongoing India-Pakistan tensions, particularly over Jammu & Kashmir (covered in the next chapter).
