By 1560 all the Finnic and Tatar tribes between the Oka and the Kama had become Russian subjects.
He is, moreover, the warm advocate of the theory of its Ugrio-Finnic origin, as established by the Uralian traveller Anthony Reguly, the result of whose labours Hunfalvy published in 1864, under the title A Vogul fold es nep (The Vogul Land and People).
In 907, with a host made up of all the subject tribes, Slavonic and Finnic, he sailed against the Greeks in a fleet consisting, according to the lyetopis, of 2000 vessels, each of which held 40 men; but this estimate is plainly an exaggeration.
Hence, as far as any physical characters can be formulated for the various tribes (and their validity is very doubtful) the Yue-Chi type is Turkish rather than Mongol or Ugro-Finnic. In such points of temperament as military ability and power of assimilating Indian and Persian civilization, the YueChi also resemble the Turks, and some authorities think that the name Turushka or Turukha sometimes applied to them by Indian writers is another evidence of the connexion.
He civilized the north-eastern and southeastern borders of Muscovy by building numerous towns and fortresses to keep the Tatar and Finnic tribes in order.
The term Finn has a wider application than Finland, being, with its adjective Finnic or Finno-Ugric (q.v.) or Ugro-Finnic, the collective name of the westernmost branch of the Ural-Altaic family, dispersed throughout Finland, Lapland, the Baltic provinces (Esthonia, Livonia, Curland), parts of Russia proper (south of Lake Onega), both banks of middle Volga, Perm, Vologda, West Siberia (between the Ural Mountains and the Yenissei) and Hungary.
Originally nomads (hunters and fishers), all the Finnic people except the Lapps and Ostyaks have long yielded to the influence of civilization, and now everywhere lead settled lives as herdsmen, agriculturists, traders, &c. Physically the Finns (here to be distinguished from the Swedish-speaking population, who retain their Scandinavian qualities) are a strong, hardy race, of low stature, with almost round head, low forehead, flat features, prominent cheek bones, eyes mostly grey and oblique (inclining inwards), short and flat nose, protruding mouth, thick lips, neck very full and strong, so that the occiput seems flat and almost in a straight line with the nape; beard weak and sparse, hair no doubt originally black, but, owing to mixture with other races, now brown, red and even fair; complexion also somewhat brown.
In many cases the Sky has been already resolved into the visible firmament and its lord and owner, like the Yoruban Olorun or the Finnic Ukko.
