Princely state
The State of Khairpur (، ), also transliterated as Khayrpur, was a princely state of British India on the Indus River in northern Sindh, modern Pakistan, with its capital city at Khairpur. It was established as capital for the Sohrabani branch of the Talpur dynasty, and was established shortly after Talpur ascendency in 1783 as one of several Talpur dominions. Whereas the other Talpur dominions were conquered by the British in 1843, the Khairpur state entered into treaty with the British, thereby maintaining some of its autonomy as a princely state. The last Mir of Khairpur opted to join the new state of Pakistan in 1947, and the dominion was thus made a Princely state of Pakistan, until it was fully amalgamated into West Pakistan in 1955.
