The opening as it read in 2010

Siege of Herat was part of the Islamic conquest of Persia . Caliph Umar (634-644 CE) launched an offensive against the Sassanid Persian Empire in 642 and by late 643 almost all of the Sassanid empire was conquered, except Khurasan and Armenia . A veteran military commander, Ahnaf ibn Qais , was appointed by Umar for the conquest of Khurasan, which in those time comprises most of present-day north eastern Iran , Afghanistan and Turkmenistan . By mid-644 Ahnaf had captured Khurasan and the last Sassanid emperor Yazdegerd III was defeated in his last struggle against Caliphate at the Battle of Oxus river , whereupon he fled to China . He returned to Bactria during Caliph Uthman 's reign where he was once again defeated and eventually was murdered by a miller in 651. With him ended the last non-Muslim Persian dynasty.1
