Durand Line Dispute

The Durand Line is the boundary drawn in 1893 between Afghanistan and British India, which became the Afghanistan-Pakistan frontier after Pakistan’s creation. The dispute concerns Afghanistan’s historical challenges to the boundary’s legitimacy and Pakistan’s position that it inherited a legally binding international border.

The colonial agreement of 1893

The boundary originated in an agreement concluded in 1893 between Amir Abdur Rahman Khan of Afghanistan and Sir Mortimer Durand, representing British India. It sought to delimit their respective spheres of influence along Afghanistan’s eastern and southern frontier.

• The agreement formed part of British efforts to secure India’s northwestern frontier while maintaining Afghanistan as a buffer against Russian expansion.
• The line divided Pashtun-inhabited territories between Afghanistan and British India rather than bringing all Pashtun communities within one political unit.
• The frontier arrangements were subsequently reaffirmed, including through the Treaty of Rawalpindi, 1919; the dispute therefore involves later agreements as well as the original settlement.

Why partition turned it into an interstate dispute

When Pakistan emerged in 1947, it inherited British India’s territory adjoining Afghanistan. Pakistan regarded the existing frontier as continuing through state succession, while Afghanistan challenged the legitimacy of treating the colonial settlement as a permanent boundary.

• Pakistan maintains that a change from British rule to independence did not invalidate the boundary agreements.
• Afghan objections have questioned the circumstances and legitimacy of the original agreement, portraying it as a settlement imposed under unequal colonial conditions.
• During the transfer of power, the referendum in the North-West Frontier Province offered a choice between India and Pakistan, not an independent Pashtun state or union with Afghanistan.

The Pashtun question behind the territorial disagreement

The Pashtun question gives the dispute an ethnic and political dimension beyond the interpretation of treaties. Communities on either side retain linguistic, tribal and kinship connections despite the international boundary.

• Afghan support for Pashtunistan, broadly meaning a separate political homeland for Pashtuns, brought the issue into conflict with Pakistan’s territorial integrity.
• The dispute combines competing interpretations of colonial agreements with competing principles: inherited territorial boundaries on one side and claims of ethnic self-determination on the other.
• Cross-border social ties help explain the frontier’s sensitivity, but shared ethnicity does not itself settle the legal status of an international boundary.
