Wazir Ali Khan (19 April 1780 – 15 May 1817) was the fourth Nawab wazir of Oudh from 21 September 1797 to 21 January 1798 and the adopted son of Asaf-Ud-Daulah.
Life
He was the adopted son of Asaf-ud-Daulah, who had no son. He adopted a boy who was the son of his sister. At 13 years of age, Ali was married at the cost of £300,000 in Lucknow.
After the death of his surrogate father in September 1797, he ascended to the throne (musnud), with the support of the British. Within four months they accused him of being unfaithful. Sir John Shore (1751–1834) then moved in with 12 battalions and replaced him with his uncle Saadat Ali Khan II.
