The chief, whose title is nawab, is a Mahommedan, of Afghan descent.
On the west the shahzada or imperial prince, known afterwards as the emperor Shah Alam, with a mixed army of Afghans and Mahrattas, and supported by the nawab wazir of Oudh, was advancing his own claims to the province of Bengal.
At the same time the nawab made a grant to the company of the zamindari rights over an extensive tract of country round Calcutta, now known as the district of the Twenty-four Parganas.
But there was a traitor in the Mahommedan camp in the person of Mir Jafar, who had married a sister of the late nawab, Ali Vardi Khan.
The superior lordship, or right to receive the quit rent, remained with the nawab; but in 1759 this also was parted with by the nawab in favour of Clive, who thus became the landlord of his own masters, the company.
