Ukraine
By the middle of the 4th century AD, Antes joined other tribes and established a state under their rule.  Their state fell under the pressure of  Avars in 602 AD and their name was longer mentioned.  Since the 7th century over 10 tribal groups joined under the name "Slavs" and made their own state named Rus.  The chronicles mention three centers that formed this state: Kuyavia (Kyiv land with Kyiv itself), Slavia (Novgorod land), and Artania (exact location unknown).
