Description
The border begins at the tripoint with Turkmenistan in the
Harirud river before proceeding overland just to the east of the Iranian town of
Taybad. The border then follows a series of short straight lines, passing through the Daryache-ye Namakzar and the
Daqq-e Patergan salt lakes; two 'beaks' of Iranian territory protrude into Afghanistan along this section. The middle 'Turkish section' (''see below'') consists of a series of straight lines through a plain, with some mountains to the south, ending at Kuh Siah mountain, where the border veers sharply to the east. It cuts through
Hamun Lake before turning south, where it follows the Juy-e Siksar River down to the confluence with the
Helmand River
The Helmand river (Pashto/Dari: ; Ancient Greek: Ἐτύμανδρος, ''Etýmandros''; Latin: '), also spelled Helmend, or Helmund, Hirmand, is the longest river in Afghanistan and the primary watershed for the endorheic Sistan Basin. It o ...
. The border is then formed of a long straight line segment going southwest to the tripoint with Pakistan at the Kuh-i-Malik Salih mountain.
The border traverses a generally arid, inhospitable region with few inhabitants, except in the Zabol-Zaranj area where the main border crossing is located.

and Afghanistan was formalised in the period 1872–1935 by a series of third-party arbitrations, stemming from the
Treaty of Paris (1857)
The Treaty of Paris (1857) () marked the end of the hostilities of the Anglo-Persian War. On the Qajar Iran, Persian, side negotiations were handled by ambassador Farrokh Khan. The two sides signed the peace treaty on 4 March 1857.''The Middle Ea ...

A series of skirmishes between Afghanistan and Iran in the 1860s prompted the

, to request that the British formalise the Afghan-Iran boundary. A rough delimitation was proposed in 1872 by a committee headed by Sir
Frederic John Goldsmid following a line from Banda to Kuh-i-Malik Siah (a hill at the modern Afghanistan-Iran-Pakistan tripoint) via the
Helmand River
The Helmand river (Pashto/Dari: ; Ancient Greek: Ἐτύμανδρος, ''Etýmandros''; Latin: '), also spelled Helmend, or Helmund, Hirmand, is the longest river in Afghanistan and the primary watershed for the endorheic Sistan Basin. It o ...
. Both parties eventually accepted this proposal however it was not implemented further at that time.
The Goldsmid boundary proved to be inadequate, especially given the shifting of the course of the Helmand, and thus a more precise boundary was drawn up in three sections over the following decades: the northern section by General C.S. MacLean, British consul general for Khorasan and Sīstān, in 1888–91, the southern section by Colonel Sir
Henry McMahon in 1903–05 and finally the middle section by

After each demarcation boundary pillars were erected, leading to a total of 172 pillars being erected in the non-riverine sections of the border.
The boundary itself was not disputed after 1935, however disputes over the allocation of water resources in the region rumbled on for many years and were not finally resolved until 1973.
