How the rulers of Bengal went from Mughal power brokers to British pensioners

In short: In the early 18th century, the Nawabs of Bengal governed a wealthy, proto-industrial powerhouse that served as the financial engine of the Mughal Empire. Yet, within decades, internal strife and military defeats transformed these independent monarchs into mere figureheads under the total control of the British East India Company.

The rise of the Nawabs began as the Mughal Empire decentralized. Murshid Quli Khan, originally a provincial premier, consolidated the offices of viceroy and prime minister to become the de facto ruler of Bengal, Bihar, and Orissa. By 1717, Emperor Farrukhsiyar formally recognized him as the hereditary Nawab Nazim. Based in Murshidabad, these rulers presided over a region that was the wealthiest in the empire, fueled by a massive global demand for muslin, silk, and saltpetre. They maintained a sophisticated administration, backed by powerful financiers like the Jagat Seth family, and even issued coins in the name of the Mughal emperor while acting as sovereign monarchs.

However, this prosperity faced severe challenges. Nawab Alivardi Khan spent sixteen years defending his territory against relentless Maratha raids, which devastated the civilian population and forced him to pay a massive annual tribute of Rs. 1.2 million. Simultaneously, the Nawabs struggled to maintain authority over rebellious zamindars in Bihar and faced internal threats, including Afghan mutinies. These pressures, combined with the growing influence of European trading companies, created a volatile environment. The British East India Company, initially one of many foreign entities operating in the region, began to aggressively challenge the Nawab's authority.

The turning point arrived in 1757 at the Battle of Plassey, where the British defeated Siraj-ud-Daulah, the last independent Nawab, after his commander Mir Jafar defected. This victory effectively ended the Nawabs' sovereignty. Subsequent rulers, such as Mir Qasim, attempted to reclaim power but were defeated at the Battle of Buxar in 1764. By 1765, the British secured the right to collect revenue, establishing a system of dual governance that stripped the Nawabs of real power. By the time the British Crown assumed direct control in 1858, the title had become purely symbolic. The final titular Nawab, Mansur Ali Khan, abdicated in 1880, marking the formal end of an era that had once defined the economic heart of India.
