Explanation: The context of this question is rooted in the early stages of British colonial expansion in India, particularly in the region of Bengal. The East India Company, a British trading company, had established a presence in Calcutta (now Kolkata) and began to fortify their settlements. This fortification was seen as a threat by Siraj-ud-Daulah, the Nawab of Bengal, who was the ruler of the region at the time.
Siraj-ud-Daulah objected to the fortification of Calcutta by the East India Company in 1756. The fortification was a strategic move by the East India Company to protect their trading interests and to establish a stronger foothold in the region. However, this action was perceived as a violation of the terms of the agreement between the Nawab and the Company, which did not allow the Company to fortify their settlements without the Nawab's permission.
The Nawab's objection to the fortification was a significant event that led to a series of conflicts between the Nawab and the East India Company. The most notable of these conflicts was the Battle of Plassey, which took place in 1757. The Battle of Plassey was a decisive victory for the East India Company, and it marked the beginning of British colonial rule in Bengal and eventually the rest of India.
The fortification of Calcutta by the East India Company in 1756 was a pivotal moment in the history of British colonialism in India. It set the stage for the subsequent events that would lead to the establishment of British rule in the region. Understanding the timeline and the sequence of events is crucial for comprehending the broader context of British colonial expansion in India.
In summary, the correct answer is that Siraj-ud-Daulah objected to the fortification of Calcutta by the East India Company in 1756. This event was a precursor to the Battle of Plassey in 1757, which was a turning point in the history of British colonialism in India.
