The history of Slovakia dates back to the findings of ancient human artifacts. This article shows the history of the country from prehistory to the present day.

Samo founded the first recorded political union of Slavic tribes, known as Samo's Empire, ruling from 623 until his death in 658. According to Fredegarius, the only contemporary source, Samo was a Frankish merchant who unified several Slavic tribes against robber raids and violence by nearby settled Avars, showing such bravery and command skills in battle that he was elected "King of the Slavs". In 631, Samo successfully defended his realm against the Frankish Kingdom in the three-day Battle of Wogastisburg.
