In 18, the British concluded a treaty with him, by which half of his dominions were ceded to the East India Company, in return for perpetual British protection of Oudh, from all internal and external disturbances and threats (the British were to later renege on this promise). The districts ceded (then yielding a total revenue of 1 Crore & 35 Lakhs of Rupees) are as under:

Following the cessation, he reduced the Oudh Army from 80,000 to 30,000 men. He had three sons, Ghazi ad-Din Haydar, Shams-ud-daula, and Nasser-ud-daula. His son Ghazi ad-Din succeeded him, and later his grandson, Nasser ad-Din Haydar. After that, his son Nasser-ud-daula succeeded the throne, whilst his grandson, Iqbal-ud-daula, son of Shams-ud-daula, made claims to the throne in 1838. It is important to note that Saadat Ali Khan preferred his son Shams-ud-daula and desired to proclaim his heir, but was prevented by British interference. Most of the buildings between the Kaiserbagh and Dilkusha were constructed by him. He had a palace called Dilkusha Kothi designed and built by Sir Gore Ouseley in 1805.
