I had missed this.
The North-West Frontier Province of Pakistan was renamed Khyber Pakhtunkhwa by the Constitution (Eighteenth Amendment) Act 2010, which received the presidential assent on April 19.
The British conquered the area from the Sikhs in the 1840s and created NWFP as the frontier province of the Raj in 1901. Astonishingly, it retained its name past partition and independence until this year. I spent a happy few weeks there in late 1978, a year before the Russian invasion of Afghanistan (fond memories of Green’s and Dean’s in Peshawar). Renaming the province shakes off a British conception of a frontier and implies solidarity with the Pashtun, who dominate southern Afghanistan, and a rejection of the 1893 Durand Line Agreement.
The Pashtun (Pathan) are a Persian people, like the Tajik of northeast Afghanistan.
