Provinces of Afghanistan

Its name meaning Land of the Afghani, AFGHANISTAN virtually has the same border for about a century or so. However, Afghanistan's provinces (Afghan singular and plural word: velayat) have changed often. In fact, four provinces have been created since the publishing of Gwillim Law's 1999 book (citation below). In the early twenty-first century, Daykundi was created from northern Oruzgan Province, Khost (Khowst) was formed from eastern Paktia, Nuristan (Nurestan) existed as a region for quite awhile before being converted into a province in 2002, and Panjshir was created in what was formerly northeast Parvan.
