With an estimated thirty million or more in Pakistan, twelve million in Afghanistan, and perhaps a million or more in a global diaspora, Pashtuns or Pukhtuns comprise a complex ethno-linguistic population with a rich cultural tradition and literature, varied political and economic contexts, and diverse national and Islamic identities. Historic and literary references to communities that have been thought to identify “Afghans” date to the 10th century and, according to the source and scholar consulted, many centuries earlier. The assumption of any uniquely “Pashtun” identity as equivalent to the diverse “Afghan” cultural, religious, and ethnic identities that evolved over centuries has obfuscated a full understanding of the emergence of distinct regional Pashtun ethno-linguistic communities and the origins of frequently studied cultural idioms. Millions of Pashtuns have lived in close and daily contact with many other ethnic groups (Tajiks, Hazaras, Uzbeks, Turkmen, Baluch, Punjabis, etc.), and color-coded maps of ethnic homelands in Afghanistan and Pakistan are best seen as guides to often complex social geographies rather than absolute markers of ethnically pure settlement areas. For perhaps a thousand years, Pashtuns and regional forefathers have circulated within imperial and merchant networks connected by Silk Road pathways, Persian and north Indian trade routes, and Indian Ocean sea lanes. Pashtuns sought livelihoods as horse traders, military entrepreneurs, agrarian pioneers, and regional rulers in the northern, eastern, and Deccan regions of India. An Afghan state with variable territorial claims consolidated after 1747. Leading Pashtun clans from around Kandahar and the eastern districts took positions in the dynasties that soon ruled from Kabul and core provinces. Pashtuns between the Oxus and Indus rivers adapted to, avoided, and served 18th- and 19th-century Russian and British imperial economic and political forces. In the high European “new imperialism” of the late 19th and early 20th centuries, Afghan territories were framed by treaty-negotiated boundaries. Never colonized, Afghanistan became economically dependent on British–India subsidies and linkages. Into the mid-20th century, Afghanistan’s Pashtun political dynasties and Islamic and political activists on both sides of the British-Indian Durand Line offered leadership and alternative visions of the future to anticolonial and Muslim nationalists, including those in British India. In recent decades, core Pashtun homelands and diasporic communities have fully experienced the disruptions and violence that followed the partition of British India in 1947, postcolonial “national” consolidation, conflict between India and Pakistan over Kashmir, Cold War alliances and conflict, the rise and fall of the Taliban, and civil war. Like others, Pashtun lives were shaped by the transnational dynamics of economic globalization, urbanization, migration, and the international crises that traumatized the world after September 11, 2001.
