Qajar irredentism brought Persia to make some advances in Baluchistan in the 1830s and 1840s, but in early 1860s, the continuation of this advance was threatened by one of Britain's main imperial interests and needs: the Indo-European telegraph line, which was to cross the Makran Coast overland. Persia sought to use this need for getting British recognition for its claims over Baluchistan. This put the British under pressure, for they did not wish to alienate Persia, through whose territories the line was to pass. The British government tried to appease the Persians with a simple declaration that the telegraph would not affect their claims and by taking the telegraph away from disputed territories. One major thing was faulty in this “solution,” for it was the British who decided which territories were “disputed” or “undisputed,” not the Persians.
