Biography
The Razgildeevs were a Baikal Cossack family, originating from the Trans-Baikal region. The head of the family, Anempodist Ivanovich Razgildeev, also known as Aleksandr, had served at Chindant, and then at Aksha as a border commandant with the rank of major. From there he moved to Kyakhta in 1842, and then to Verkhneudinsk, where he was chieftain of the Trans-Baikal Cossack Regiment. His son,, served in the army, rising to the rank of general. Anempodist's younger brother, Yevgraf Ivanovich Razgildeev, had four sons, Ivan, Aleksandr, Mikhail and Andrei. They studied at Nerchinsk Mining School and then at the in Saint Petersburg. Ivan Razgildeev was born in the village of Tsurukhaytuy in Irkutsk Governorate, now Priargunsk, in 1811. He became the head of the Nerchinsk gold mining operations, gaining a reputation for cruelty. He was later replaced by his brother Mikhail. Of the other brothers, became a prominent architect, while Andrei was a land planner for private gold mining enterprises in the Verkhnevilyuysky and Olyokminsky Districts.Ivan Razgildeev graduated from the Mountain Cadet Corps in 1830 with a silver medal. He participated in the geological exploration of the and discovered the Altangan gold deposits in the Tsagan-Oluysky valley, now part of the modern Borzinsky District. He was manager of the gold mines established along the Kara River from 1850 until 1852, and then the works around Nerchinsk from 1852 to 1856. The mining works used prison labour from inmates exiled to Siberia, termed katorga, with the Kara and Nerchinsk katorgas being particularly infamous examples. During Razgildeev's tenure, round-the-clock mining, and the use of an ore-washing of his own invention, allowed an annual gold production of some 100 pounds. The particularly harsh conditions during this period gave rise to the term "Razgildeevshchina", and an investigation was opened into conditions. Razgildeev was brought to trial in 1855, but was protected by the Governor of East Siberia, Nikolay Muravyov-Amursky, and was acquitted.
