1. The Independent Nawabs of Bengal
As the Mughal Empire declined, Bengal became practically independent under a series of strong rulers.
Murshid Quli Khan: The first Nawab who shifted the capital from Dhaka to Murshidabad.
Alivardi Khan: He kept the European companies (British and French) under strict control and prevented them from fortifying their factories.
Siraj-ud-Daulah: The young, impulsive Nawab who directly challenged the British, leading to the famous Black Hole Tragedy (where British prisoners were allegedly suffocated in a small room).
2. The Turning Points: Plassey and Buxar
These two battles changed the course of Indian history forever.
A. Battle of Plassey (1757)
Conflict: Siraj-ud-Daulah vs. Robert Clive.
The Treachery: The Nawab’s commander, Mir Jafar, took a bribe from the British and stayed out of the battle.
Result: The British won. Bengal’s wealth began to drain toward England. Mir Jafar was made a "Puppet Nawab."
B. Battle of Buxar (1764)
Conflict: The British vs. a combined alliance of Mir Qasim (Nawab of Bengal), Shuja-ud-Daulah (Nawab of Awadh), and Shah Alam II (Mughal Emperor).
Result: The British won decisively.
Treaty of Allahabad (1765): The British obtained the Diwani Rights—the right to collect taxes from Bengal, Bihar, and Odisha. They were now the masters of the richest province in India.
3. The Dual Government (1765–1772)
Robert Clive introduced a "Dual System" where:
The British had the power (Diwani/Revenue) but no responsibility.
The Nawab had the responsibility (Administration/Justice) but no power or money.
Impact: This led to total chaos and the Great Bengal Famine of 1770, where one-third of the population perished.
4. The Bengal Renaissance (19th Century)
Bengal became the intellectual capital of India. This was a period of social and cultural reform.
Raja Ram Mohan Roy: Known as the "Father of Modern India." He founded the Brahmo Samaj and fought against Sati.
Ishwar Chandra Vidyasagar: Played a key role in the passing of the Hindu Widow Remarriage Act (1856).
Literature: Writers like Bankim Chandra Chattopadhyay (wrote Vande Mataram) and Rabindranath Tagore shaped the national identity.
5. The Partition of Bengal (1905)
This was a "Divide and Rule" tactic by Lord Curzon.
The Official Reason: To make the large province easier to administer.
The Real Reason: To weaken the nerve center of Indian nationalism and create a rift between Hindus (West Bengal) and Muslims (East Bengal).
The Reaction: * People tied Rakhi on each other's wrists as a symbol of unity.
The Swadeshi and Boycott Movements were launched.
The partition was eventually annulled (cancelled) in 1911, and the capital of British India was shifted from Calcutta to Delhi.
