Yerbogachen

 village, district center

Yerbogachen (Russian: Ербогачён), sometimes written Erbogachen or Erbogachene, is a rural locality in Irkutsk Oblast, Russia, located on the Nizhnyaya Tunguska River. It is the administrative center of Katangsky District. Population: 1,965 (2010 Census).
Yergobachen was founded in 1786 by Russian fur hunters not far from an Evenk settlement. The name - the original name was Nerbeketschen (Нэрбэкэчэн) - which goes back to the Evenki nerbeke for a "pine -covered hill". From 1925 the village belonged to the Preobrazhensky Life Guards Regiment based in the 140 km upstream (to the south) village of Preobrazhenka, until it was merged in 1929 in the Kirensky rajon based in Kirensk an der Lena. On December 10, 1930, Jerbogatschon became the administrative seat of the newly formed Evenki national rajon Katanga (Russian Katangski nazionalny (Ewenkijski) rajon, after the name Katanga for the upper reaches of the Stony Tunguska in the western part of the area). During this time, the town's economy expanded to include coal mining and other industries. Before 1940 the rajon lost the status of a national rajon and has borne its current name ever since.
