Durand Line

Durand Line. The Durand Line is the 2,670-kilometer international boundary established in 1893 between Afghanistan and what was then British India, now modern Pakistan. It was demarcated by a diplomatic mission led by British civil servant Mortimer Durand and the Emir of Afghanistan, Abdur Rahman Khan. The line's creation was a pivotal event in the Great Game, the strategic rivalry between the British Empire and the Russian Empire, and has remained a source of political contention and regional instability since the Partition of India in 1947.

Historical background

The Durand Line originated from the geopolitical pressures of the late 19th century, as the British Raj sought to secure its northwestern frontier against potential Russian encroachment. Following the Second Anglo-Afghan War, British diplomat Mortimer Durand was dispatched to Kabul to negotiate a formal agreement with Abdur Rahman Khan. The resulting Durand Line Agreement, signed in November 1893, aimed to delineate spheres of influence and stabilize the volatile border region. This agreement was part of a series of British frontier policies that included the creation of the North-West Frontier Province and interactions with tribal agencies like the Khyber Agency and the Waziristan region. Subsequent treaties, such as the Treaty of Rawalpindi in 1919 following the Third Anglo-Afghan War, reaffirmed the boundary, though Afghan rulers later contested its legitimacy.

Demarcation and geography

The demarcation process involved joint surveys and the placement of markers across rugged terrain, stretching from the Hindu Kush mountains in the north to the Balochistan region in the south. Key geographical features along its path include the Khyber Pass, a historically vital trade and invasion route, and the Gomal Pass. The line divides several major ethnic regions, notably cutting through the traditional lands of the Pashtun people and the Baloch people. Major cities and towns proximate to the boundary include Jalalabad and Spin Boldak on the Afghan side, and Peshawar, Quetta, and Landi Kotal on the Pakistani side. The border traverses the provinces of Kandahar, Helmand, and Nangarhar in Afghanistan, and Khyber Pakhtunkhwa and Balochistan in Pakistan.

Political and diplomatic status

The political status of the boundary is a persistent diplomatic dispute. The government of Afghanistan has never formally recognized it as an international border, a position upheld by successive regimes from the Kingdom of Afghanistan to the Islamic Republic of Afghanistan and the former Taliban government. Pakistan, since its independence, considers it a settled international frontier inherited from the British Empire and upheld by international law, notably the principle of uti possidetis juris. Key moments of tension include the Afghanistan–Pakistan skirmishes and the diplomatic crisis following the Torkham border closure in 2016. International bodies like the United Nations and major powers including the United States and the Soviet Union have generally treated it as the de facto border, though without universally resolving the underlying legal dispute.

Impact on ethnic groups and tribes

The imposition of the boundary had a profound and divisive impact on the region's ethnic groups, particularly the Pashtun people, whose traditional territory was bifurcated. Major tribal confederacies such as the Durrani, the Ghilji, the Wazir, and the Mahsud found their communities separated. This division disrupted traditional migratory patterns, social structures, and tribal *jirga* systems. The line also affected the Baloch people, dividing their population between Iran, Pakistan, and Afghanistan. These artificial divisions fueled cross-border kinship ties and a sense of irredentism, encapsulated in the political concept of Pashtunistan advocated by figures like Khan Abdul Ghaffar Khan and during the rule of Mohammed Daoud Khan.

Border disputes and conflicts

The disputed status has been a direct cause of numerous military clashes and diplomatic incidents. Significant conflicts include the Afghanistan–Pakistan border skirmishes of 1949–50 and the Bajaur Campaign of 1960–61. The Soviet–Afghan War and the subsequent Afghan Civil War saw the border become a conduit for mujahideen fighters and refugees. In the 21st century, the War in Afghanistan (2001–2021) intensified cross-border tensions, with incidents like the Angoor Ada raid and repeated shelling across the Chaman border crossing. Pakistani military operations such as Operation Zarb-e-Azb in the Federally Administered Tribal Areas were partly driven by militancy emanating from the border region.

Economic and security implications

The border region is a critical yet challenging zone for trade and security. Major transit points like Torkham and Chaman facilitate the Afghanistan–Pakistan Transit Trade Agreement, but are frequently disrupted by closures due to security concerns or diplomatic spats. The area is a hub for the illicit trade of arms, narcotics, and smuggling, linked to networks like the Quetta Shura. Security challenges are compounded by the presence of militant groups including the Tehrik-i-Taliban Pakistan, the Haqqani Network, and factions of the Islamic State – Khorasan Province. To control movement, Pakistan has constructed extensive border fencing and outposts, a project initiated by the Pakistan Army under General Qamar Javed Bajwa, which has been a source of further bilateral friction.
