A. Historical Periods

Khilji Rule – Ikhtiyar Uddin Muhammad bin Bakhtiyar Khilji (1204–1206)

Conquests: Entered Bengal with only a few horsemen, making a surprise attack on Nadia (1204), the capital of the Sena dynasty. Raja Lakshman Sena fled to Bikrampur.
Capital: Made Gaur/Lakhnauti his capital.
Contributions:
- Established mosques, madrasas, and khanqahs to spread Islam.
- Laid the foundation of Muslim society in Bengal.
End of Rule: Attempted to invade Tibet (1206) but faced harsh weather, food shortages, and disease. Defeated and humiliated, he returned to Devkot. Soon after, he either died of fever or was assassinated by his subordinate, Ali Mardan Khilji. 👉 His death ended his short but decisive rule, though he opened the door for Muslim governance in Bengal.

Delhi Rule – Tughral Tughan Khan (1236–1246)

Background: Appointed governor of Bengal by the Delhi Sultanate.
Territory: Instead of consolidating Bengal, he focused on north Indian affairs and briefly occupied Tirhut (Bihar).
Challenges: Faced attack from Narasimhadeva I of Orissa, whose forces advanced as far as Lakhnauti.
Downfall: Tughan Khan asked for help from Delhi. Though the Orissan army retreated, Delhi’s general Tughlaq Tamar Khan seized Bengal for himself. Tughan Khan was forced to flee to Delhi (1246). 👉 His rule ended with betrayal and loss of Delhi’s direct grip on Bengal, showing Bengal’s difficulty staying tied to Delhi.

Independent Sultanate – Sikandar Shah (1357–1389)

Background: Son of Shamsuddin Ilyas Shah, 2nd Sultan of the Ilyas Shahi dynasty.
Delhi Invasion: In 1359, Delhi Sultan Firuz Shah Tughlaq invaded Bengal and supported a rival, Zafar Khan Fars.
Ekdala Fort: Sikandar Shah retreated to Ekdala, a strong fort. The Delhi army besieged it, but the Bengal army used the monsoon rains and local terrain to resist.
Outcome: A treaty was signed — Delhi withdrew, and Bengal’s independence was formally recognized.
Contributions: Constructed the Adina Mosque (Malda) — the largest mosque in the subcontinent for centuries. 👉 His reign strengthened Bengal’s independence and identity, blending political resilience with cultural achievements.

Mughal Period – Murshid Quli Khan (1717–1727)

Background: Born in Deccan, served as revenue officer under the Mughals. Later became Dewan of Bengal and shifted capital from Dhaka to Murshidabad.
Independence: Although nominally loyal to the Mughal Emperor in Delhi, he became virtually independent due to Mughal decline. He sent annual tribute (1 crore 3 lakh taka) but ruled freely.
Contributions:
- Introduced revenue reforms — land surveys, fixed revenue according to tenants’ capacity.
- Encouraged trade and commerce → allowed English, French, and Persian merchants to flourish.
End of Rule: Died in 1727, leaving Bengal wealthy but politically vulnerable. His successors were weaker, which later paved the way for the British to interfere. 👉 His era is remembered as a golden period of Bengal’s prosperity, though short-lived.
