The history of Islamabad, Pakistan’s purpose-built federal capital, bridges ancient civilization with mid-20th-century modern urban planning. While the modern metropolis was carved out in the 1960s, archaeological excavations along the Potohar Plateau and Soan River valley reveal prehistoric human habitation belonging to the ancient Soanian culture, which was later influenced by the Buddhist Gandhara civilization, leaving behind relics like the Shah Allah Ditta caves and the Ban Faqiran stupa. In 1958, President General Ayub Khan conceived the idea of a new capital to replace the coastal city of Karachi, which was deemed too vulnerable to naval attack and overly congested by commercial interests. In 1960, Greek architect Constantinos Apostolou Doxiadis designed a futuristic grid-based master plan that organized the territory into distinct triangular sectors (such as the Administrative, Diplomatic, and Residential zones) situated safely against the scenic backdrop of the Margalla Hills. Construction began in 1961 under the Capital Development Authority (CDA), and by 1967, the government officially shifted its operations into the new city, which evolved over the following decades into a major geopolitical and architectural hub marked by iconic landmarks like the massive Shah Faisal Mosque completed in 1986.
