Yellow Ukraine (Ukrainian: Жовтий Клин, romanized: Zhovtyi Klyn, lit.
'Yellow Wedge'), also known as Zhovty Klyn, is a historical territory with significant Ukrainian settlement in Volga Region.
The settlement of Zhovty Klyn (the Yellow Wedge) started soon after the Pereiaslav agreement as the eastern border of the second Zasechnaya Cherta.
In addition to Ukrainians, Volga Germans and Mordovians migrated to Zhovty Klyn in numbers.
As of 2014[update], most of the population is mixed in the region, though a few "pure" Ukrainian villages remain.
