The Goldsmid Line in the early 1870s, was demarcated by the British Raj, driven equally by the impulse to clarify British India's frontiers and establish buffers, demarcated what is now the successor Pakistan-Iran border through the Goldsmid Line. Sir Frederic John Goldsmid also arbitrated and settled the Iran-Afghanistan border with this respectively. The 909-km Iran-Pakistan border, known as the Goldsmith Line, stretches from a tripoint with Afghanistan to the northern Arabian Sea.
