On the birth of Avicenna's younger brother the family migrated to Bokhara, then one of the chief cities of the Moslem world, and famous for a culture which was older than its conquest by the Saracens.
He accomplished a successful campaign in 1868 against Bokhara, capturing Samarkand and gradually subjugating the whole country.
After this he revisited Syria and Asia Minor, and crossed the Black sea, the desert from Astrakhan to Bokhara, and the Hindu Kush.
He travelled through Russia to Bokhara, and returned by.
With the opening of the Russian railway from the Caspian to Merv, Bokhara and Samarkand in 1886-1887, Russian manufacturers were enabled to compete in Central Asia with their western rivals, and the value of European manufactures passing Meshed in transit was much reduced.
