Mughal Firman

In return for the Awadhian provinces Clive secured from the emperor one of the most important documents in British history in India, effectively granting title of Bengal to Clive. It appears in the records as " firman from the King Shah Aalum, granting the diwani rights of Bengal, Bihar and Odisha to the Company 1765." The date was 12 August 1765, the place Benares, the throne an English dining-table covered with embroidered cloth and surmounted by a chair in Clive's tent. It is all pictured by a Muslim contemporary, who indignantly exclaims that so great a "transaction was done and finished in less time than would have been taken up in the sale of a jackass". By this deed the company became the real sovereign rulers of thirty million people, yielding a revenue of £4,000,000 sterling (equivalent to £690,000,000 in 2023).

On the same date Clive obtained not only an imperial charter for the company's possessions in the Carnatic, completing the work he began at Arcot, but a third firman for the highest of all the lieutenancies of the empire, that of the Deccan itself. This fact is mentioned in a letter from the secret committee of the court of directors to the Madras government, dated 27 April 1768. The British presence in India was still tiny compared to the number and strength of the princes and people of India, but also compared to the forces of their ambitious French, Dutch and Danish rivals. Clive had this in mind when he penned his last advice to the directors, as he finally left India in 1767:

"We are sensible that, since the acquisition of the dewany, the power formerly belonging to the soubah of those provinces is totally, in fact, vested in the East India Company. Nothing remains to him but the name and shadow of authority. This name, however, this shadow, it is indispensably necessary we should seem to venerate."
