When Pakistan gained independence in 1947, the southern port city of Karachi was its provisional national capital. In 1958, a commission was constituted to select a suitable site near Rawalpindi for the national capital with particular emphasis on location, climate, logistics, and defence requirements, along with other attributes. After extensive study, research, and a thorough review of potential sites, the commission recommended the area northeast of Rawalpindi in 1959. In the 1960s, Islamabad was constructed as a forward capital for several reasons. Karachi was also located at the southern end of the country, and exposed to attacks from the Arabian Sea. Pakistan needed a capital that was easily accessible from all parts of the country. Karachi, a business centre, was also considered unsuitable partly because of intervention of business interests in government affairs. The newly selected location of Islamabad was closer to the army headquarters in Rawalpindi and the disputed territory of Kashmir in the north.
