The correct option is The American Civil War.
Explanation
The "Cotton Boom" in the Bombay Deccan during the 1860s was a temporary period of high demand and rising prices for Indian cotton, driven by a crisis in the global supply chain.
Analysis:
- The American Civil War (1861-1865): Prior to 1861, the textile industries of Britain (Manchester) were heavily dependent on cotton imports from the United States. The outbreak of the American Civil War disrupted this supply due to blockades, creating a "Cotton Famine" in Britain.
- Shift to India: Desperate for raw material, British manufacturers turned to India. Merchants provided easy credit and advances to peasants (ryots) in the Bombay Deccan to encourage cotton cultivation. This led to a sudden surge in production and prices, known as the "Cotton Boom."
- Aftermath: The boom ended abruptly when the Civil War concluded in 1865 and American cotton re-entered the market. The subsequent crash in prices contributed significantly to agrarian distress and the Deccan Riots of 1875.
Incorrect Options:
- The Industrial Revolution in France Industrial Revolution in France: This was a gradual process and not the specific trigger for the sudden 1860s demand spike.
- The opening of the Suez Canal Opening of the Suez Canal: The canal opened in 1869, which was after the boom had already collapsed.
- The Opium Wars in China Opium Wars in China: These conflicts related to the opium trade and diplomatic relations with China, having no direct correlation to the cotton demand in the Deccan.
Key Takeaway: The American Civil War caused a global shortage of cotton, forcing Britain to procure cotton from India, which triggered the short-lived "Cotton Boom" in the Deccan.
