Omok
The Omok were the largest of the tundra Yukaghir tribes, nomadizing along the lower Kolyma and the Omolon in northeastern Sakha; their name comes from a Yukaghir word omo, meaning clan or tribe. In 1659 the Russian tally counted 620 Omok in eleven clans, 155 of them fur-tribute payers.
Warfare, the smallpox epidemics of 1669 and the 1690s and absorption by Even, Yakut and Russian neighbours had cut them to fifty-four people by 1693. Their language, an eastern Yukaghir tongue, survived into the eighteenth century, and a word list was recorded in 1821 by the explorer Fyodor Matyushkin.
