A great portion of the lands held by him were among those made over to the British Government, on the division of the Oude territory, by the treaty of 1801, concluded between Saadut Allee Khan and the then Governor-General Lord Wellesley.
The country was then divided into equal shares, according to the rent-roll at the time.

The half made over to the British Government has been ever since yielding more revenue to us, while that retained by the sovereign of Oude has been yielding less and less to him; and ours now yields, in land-revenue, stamp-duty, and the tax on spirits, two crore and twelve lacs a-year, while the reserved half now yields to Oude only about one crore, or one crore and ten lacs.

When the cession took place, each half was estimated at one crore and thirty- three lacs.

Under good management the Oude share might, in a few years, be made equal to ours, and perhaps better, for the greater part of the lands in our share have been a good deal impoverished by over-cropping, while those of the Oude share have been improved by long fallows.

Lands of the same natural quality in Oude, under good tillage, now pay a much higher rate of rent than they do in our half of the estate.
Almas Allee Khan, at the close of his life, was supposed to have accumulated immense wealth; but when he died he was found to have nothing, to the great mortification of his sovereign, who seized upon all.
