Terek
In the marshy delta of the Terek, a Russian fortified settlement known as Tersky Gorod or Terki stood on the Tyumenka, one of the river's branches near the Caspian Sea. Founded in 1588, it formed part of a succession of Russian forts on the Terek and Sunzha, whose names and locations changed over time. Terki gave Russian forces a foothold in the northeastern Caucasus, but its position was contested by the peoples and rulers of the surrounding plains and foothills.
