Siraj ud-Daulah was the last independent Nawab of Bengal, ruling from 1756 to 1757. He ascended to the throne at a young age and faced challenges from both internal rivals and the growing power of the British East India Company. His reign was marked by efforts to strengthen his authority and resist foreign influence. In 1757, Siraj ud-Daulah's conflict with the British culminated in the pivotal Battle of Plassey. Despite initial successes, he was ultimately defeated, leading to the British establishing control over Bengal. His defeat marked a significant turning point in Indian history, paving the way for British colonial rule in India.
