The first Slavs arrived to Slovakia at the end of the 5th and early 6th century. The early Slavs settled mainly in the lowlands near the water flows, the highest density of their settlements is documented just in the area of Nitra. As the Avars expanded to the territory of Slovakia in the latter half of the 7th century and early 8th century, the border between Slavic and Slavo-Avaric territory moved toward Nitra. A biritual cemetery in Nitra-Dolné Krškany lay on the northern border of mixed settlement area.
