Treaty of Amritsar (1809)

He had established a capital at Lahore in 1799, proclaimed himself maharajah of the Punjab in 1801 and expanded his territories to such an extent that by 1808 he had control of an area bounded by the Jhelum and Sutlej Rivers.

Unaware of the changed EIC outlook, Singh concluded it was best not to risk war realizing his relative military weakness and agreed to sign the updated treaty.

This enabled him to extend his rule over rival Sikh Misls and ultimately expand to areas such as Peshawar, Multan and Kashmir by defeating the Afghan Durrani Empire.

The unification of these territories aided by his French generals Westernising his armies, formed the Sikh empire that lasted until British subjugation in 1849.

[9]: 541  The treaty was successfully at halting the southern expansion of the Sikh Empire south of the Sutlej river, with Ranjit Singh instead turning his immediate focus to the Gurkha occupation in the Punjab Hills and internal conflict in Afghanistan shortly thereafter.
