The population migrated from Chuvashia in about 17th century and originally settled in Artukhovsky volost of Belebeevsky county of Orenburg province (now it is Sterlibashevsky rajon of the Republic of Bashkortostan), it is about 3-4 kilometers from village Smorodinovka, in the lands of a landowner from Saint Petersburg, not so far from a not existing currently village Baranovka.

The village Tyater’bash (the name used to be written with soft sign) became a part of the Ufa province Sterlitamak county Artukhovsky volost.

The version is supported by some part of inhabitants of today's Tyaterbash, which insist that that year the summer was really hot.
