The Samanid Empire seized Bukhara, the capital of Greater Khorasan, in AD 903. Genghis Khan besieged Bukhara for 15 days in 1220. As an important trading centre, Bukhara was home to a community of medieval Indian merchants from the city of Multan (modern-day Pakistan) who were noted to own land in the city.
