Silk Road, 7th Century Travels on the Silk Road: The river oasis Samarqand on the Zarafshon river Uzbekistan exists since more than 3500 years. It was always part of the Silk Road. Archeology and Alexander "the Great" revealed the existence of a Sogdian state, with Afrosyab (Samarqand) as its center.
