Afghanistan and Pakistan share one of the world’s most contentious borders. For decades, this boundary has been described as disputed, temporary, and illegitimate. Afghan leaders across different eras have called it unacceptable. Pakistani officials have defended it as internationally recognized. The debate has fueled tensions, closed crossings, and disrupted millions of lives.
At the center of this dispute lies a claim repeated so often that it became an unquestioned truth that the Durand Agreement of 1893 was valid for only 100 years. This assertion has appeared in newspaper columns, academic papers, and political speeches so frequently that it has shaped policy decisions and public opinion across South Asia.
There is one problem with this widely accepted narrative that the 100-year clause never existed in any official document.
The Architecture of the 100 Year Myth
The origins of this 100-year fiction trace back to an article by an Indian professor, Professor Sidhu, published in The Hindu newspaper. Professor Sidhu argued that the Durand Agreement was for 100 years and had expired; therefore, Pakistan and Afghanistan no longer shared a legal border. The claim spread rapidly, even Afghan military officer, Sher Agha Karimi, and President Hamid Karzai cited it in official statements. Pakistani academics also referenced it in their research, and the narrative took on institutional weight through sheer repetition.
When I was working on regional history, I examined the actual text of the 1893 agreement, and there was no mention of any time limitation. Article Two of the Durand Agreement states that “Afghanistan will at no time interfere on this side of the border.” At no time does not mean 100 years. It means never.
This should have been a simple matter of consulting primary sources. Yet the myth persisted because few people bothered to check the original documents. Professor Sidhu eventually removed his article from the internet once the error became clear, but by then the damage was done. The false claim had already circulated through policy circles, media outlets, and academic institutions across South Asia.
What the Historical Record Actually Shows
The Durand Agreement was not a temporary arrangement but a formal border demarcation concluded between Amir Abdur Rahman Khan and Sir Mortimer Durand in 1893. In his autobiography, Amir Abdur Rahman wrote: “I accepted this border for the betterment and peace of my state.” This was a deliberate choice made during a period when Afghanistan faced internal civil strife, tribal uprisings, and financial pressures.
The border was verified repeatedly through subsequent agreements. The Asmar Agreement confirmed the boundary after demarcation was completed in that region. The Kurram Agreement did the same for Waziristan. The Chaman Agreement addressed disputed areas near the southern border. The Rabat Agreement covered the section extending to the Iranian frontier. Each reaffirmed the same line.
In 1905, during the reign of Habibullah Khan, another agreement explicitly stated: “This is the boundary.” The 1919 Rawalpindi Agreement, following the Second Anglo-Afghan War, repeated the same recognition and also the 1921 Kabul Agreement. The final confirmation came in 1934 when the border agreement was registered with the League of Nations in both Persian and English. It remains in those archives, though most literature on the subject fails to mention it.
I spent more than a decade tracking down these documents across multiple archives in Peshawar, Quetta, Gilgit, Qatar, Nebraska, and London. What emerged was not simply evidence of one agreement but a comprehensive historical record demonstrating consistent recognition of the border across multiple governments and decades.
The Political Logic Behind Rejection
Afghanistan’s objection to the border emerged immediately after Pakistan’s independence in 1947. During the Pakistan Movement, Afghanistan argued that Pashto-speaking regions of Khyber Pakhtunkhwa and Balochistan should be transferred to Afghan control, but the British rejected this proposal.
After 1947, Afghanistan revived the claim under the banner of “Pashtunistan,” arguing these territories historically belonged to Afghanistan and should be returned. The demographic reality made this position untenable. Pakistan’s Pashtun population is nearly double that of Afghanistan’s. The economic conditions, living standards, and development trajectories of these regions differ substantially from Afghanistan.
The dispute intensified during the 1950s, 1960s, and 1970s, particularly during Sardar Daud’s government, which conducted extensive propaganda around the issue. Later administrations continued the pattern. Hamid Karzai raised it repeatedly during his presidency, and Ashraf Ghani maintained the same stance. The current Taliban government insists they do not accept the border, claiming Afghan territory extends to Attock based on historical rule.
Historical claims of this nature have little standing in international law. The Mughals ruled in Kabul, Persian dynasties controlled the region, Alexander the Great conquered it, and even Jaypal and Anandpal governed areas that included parts of present-day Afghanistan. If historical rule determines contemporary borders, the entire framework of international relations collapses into competing ancient claims.
The International Court of Justice has addressed this clearly that historical claims hold no legal value in border disputes. International law establishes that border treaties cannot be unilaterally cancelled. This principle appears consistently in international conventions and legal scholarship. Afghanistan’s selective application of this principle, only rejecting the border with Pakistan while accepting borders with Tajikistan and Turkmenistan that were originally agreed with Tsarist Russia, exposes the political rather than legal nature of the dispute.
The Legal Framework of State Succession
Afghanistan’s argument rests on the premise that agreements made with British India do not bind Pakistan because they were not directly negotiated between Afghanistan and Pakistan. International law contradicts this position.
Under the principle of state succession, Pakistan is the legal successor to British India regarding these treaty obligations. This is why Pakistan was admitted to the United Nations immediately after independence. When states fragment or new states emerge, successor states inherit the treaty obligations of their predecessors. This occurred when the Soviet Union dissolved, and multiple new nations emerged, each recognized as a successor state with continuing legal obligations.
If Afghanistan maintains confidence in its legal position, it has recourse to the International Court of Justice. That it has not pursued this avenue suggests awareness that its claims would not withstand legal scrutiny.
Nationalism Dressed as Ideology
What has become increasingly apparent since 2023 is that the Taliban government’s rhetoric has shifted from religious justification to nationalist argumentation. Despite claiming to represent an Islamic emirate, their narrative regarding the border is fundamentally ethnic and nationalist rather than religious.
This serves a specific political function. The Taliban government, lacking recognition from both the international community and significant portions of the Afghan population, deploys nationalist rhetoric to mobilize certain constituencies and legitimize their rule. They reconstructed the shrine of Ahmad Shah Abdali’s mother not as a religious policy but to appeal to nationalist sentiment. They position themselves as defenders of Afghan territorial claims to generate support from specific demographics.
This is not representative of all Afghan opinion. Many Afghan scholars, particularly from northern regions, question why settled issues are being reopened. The vocal support for Taliban border rhetoric comes primarily from specific segments, often young Afghans living abroad in the United States, United Kingdom, and Germany, influenced by the propaganda narratives of earlier decades.
The Human Dimension
The immediate victims of this manufactured controversy are ordinary people on both sides of the border. When crossings close, trade stops, families separate, and essential services become inaccessible. Afghans travel to Peshawar and Quetta for medical treatment. Border closures force them to consider far more expensive alternatives in India, assuming they can afford international travel and overcome language barriers.
These are neighboring populations with shared cultural heritage, linguistic ties, and historical connections. The dispute serves neither Pakistani nor Afghan interests. Both governments should examine who benefits from perpetual instability and who is promoting narratives that keep the border contentious rather than cooperative.
The solution is straightforward but politically difficult to normalize relations, expand trade, and facilitate people-to-people contact. Treat the border as a point of connection rather than confrontation. This requires abandoning politically convenient fictions in favor of documented reality.
A Dangerous Global Precedent
Reopening settled border disputes based on historical claims or nationalist rhetoric establishes a dangerous precedent. Belgium’s borders pass through individual buildings. Germany lost vast territories after World War II. The Roman, British, Ottoman, French, and Dutch empires once controlled enormous territories across multiple continents. Should all these borders now be contested?
International law exists precisely to prevent endless litigation of historical grievances. Borders change through military conflict and bloodshed, often at enormous human cost. They do not change through nationalist speeches or selective reading of history.
What the Evidence Demands
The documented evidence is clear and accessible that the maps do exist. The agreements are preserved in multiple archives, and the legal framework is established. I simply compiled in my book, Revisiting the Durand Line, what was always available for anyone willing to examine primary sources rather than repetition of convenient narratives.
Afghanistan does not need to rely on secondary sources or political propaganda. The archives in the British Library, Calcutta, Bombay, and Shimla contain the same files I consulted. The 1934 agreement registered with the League of Nations remains in those records. The truth has always been accessible to those willing to look.
The Taliban government lacks the military capacity to forcibly alter the border, nor should pursuing such a course even be considered, given the catastrophic consequences. Instead of addressing internal governance challenges, the current Afghan leadership raises border issues to enhance their legitimacy and satisfy specific constituencies. This strategy creates problems not just for Pakistan but ultimately for Afghanistan itself.
The border will not move. What remains uncertain is whether it functions as a barrier or a bridge, whether it generates endless friction or becomes the foundation for mutually beneficial cooperation. That choice does not rest with history or international law. It rests with the leaders and populations who must live with the consequences of either perpetuating political fictions or confronting documented reality.
