**Background:**

During the Indian Rebellion of 1857, also known as the Sepoy Mutiny, several Indian princely states and regions revolted against British rule. One such uprising occurred in Bengal, where local leaders and rebels fought against the British East India Company.

**Sijuddaulah and Kassimbazar Factory:**

Sijuddaulah was a local leader and zamindar (landlord) in the Murshidabad district of Bengal. He played a significant role in the rebellion, leading a group of rebels against the British. The Kassimbazar Factory was a British-owned indigo factory located in the same district.

**Reasons for Sijuddaulah's Capture:**

1. **Symbol of British Economic Exploitation:** The Kassimbazar Factory was a symbol of British economic exploitation in the region. The British East India Company had established indigo plantations in Bengal, forcing local farmers to cultivate indigo instead of food crops. This led to widespread agrarian distress and discontent among the local population. Capturing the factory was seen as a way to defy British economic dominance and address the grievances of the farmers.

2. **Strategic Importance:** The Kassimbazar Factory was strategically important for the British as it was a major center for indigo production. By capturing the factory, Sijuddaulah aimed to disrupt British economic activities and weaken their hold over the region. It was a strategic move to undermine British power and gain local support.

3. **Mobilizing Local Support:** The rebellion against the British required the support of the local population. By targeting the Kassimbazar Factory, Sijuddaulah intended to rally the farmers and workers who were directly affected by British policies. The capture of the factory would demonstrate the rebels' commitment to fighting for the rights and interests of the locals.

4. **Symbolic Victory:** Capturing a British-owned factory would serve as a symbolic victory for the rebels, boosting morale and inspiring others to join the uprising. It would demonstrate that the British could be challenged and defeated. The capture of the Kassimbazar Factory would also attract attention and support from other rebel groups operating in the region.

**Conclusion:**

Sijuddaulah's capture of the Kassimbazar Factory was driven by multiple factors. It aimed to address the economic exploitation of the locals, weaken British control, mobilize support, and symbolize rebellion against British rule. This act was part of a larger uprising against British dominance in India during the Indian Rebellion of 1857.

Sirajuddaulah captured Kassimbazar factory of the British because the British were meddling in the political affairs of his domain, not stopping fortifications and not paying revenues .
