What is the Durand Line — and why is the British-era border at the heart of the Pakistan–Afghanistan conflict?

The Durand Line, a contentious border established during British colonial rule, remains a focal point of conflict between Pakistan and Afghanistan. Recent airstrikes have intensified tensions, underscoring the historical grievances linked to this demarcation. Originally drawn in 1893 by Sir Mortimer Durand, the line was intended to delineate British India from Afghanistan, but it has since been contested by both nations, leading to numerous clashes and diplomatic disputes. The line divides ethnic Pashtun populations, exacerbating nationalistic sentiments and contributing to instability in the region. As accusations of territorial violations escalate, understanding the implications of this border is essential for comprehending the broader dynamics of the Pakistan-Afghanistan relationship. The ongoing violence illustrates how colonial legacies continue to influence contemporary geopolitics in South Asia, making the Durand Line not just a mere border, but a symbol of enduring conflict between the two nations.
