Group of Jewish children with a teacher, Samarkand, between 1905 and 1915. Ethnic Diversity: Jewish Children with their Teacher. Samarkand, an ancient commercial, intellectual, and spiritual center on the Silk Road from Europe to China, developed a remarkably diverse population, including Tajiks, Persians, Uzbeks, Arabs, Jews, and Russians. Samarkand, and all of West Turkestan, was incorporated into the Russian Empire in the middle of the nineteenth century and has retained its ethnic diversity up to the present. Prokudin-Gorskii captures here a group of Jewish boys, in traditional dress, studying with their teacher. Russian chemist and photographer Sergey Prokudin-Gorsky (1863-1944) was a pioneer in colour photography which he used to document early 20th-century Russia and her empire, including the vanishing way of life of tribal peoples along the Silk Route in Central Asia. In a railway-carriage darkroom provided by Czar Nicholas II, Prokudin-Gorsky used the three-colour photography process to record traditional costumes and occupations, churches and mosques - many now Unesco World Heritage sites - as well as modernisation in agriculture, industry and transport.
