The term "Slavs" designates an ethnic group of people who share a long-term cultural continuity and who speak a set of related languages known as the Slavic languages (all of which belong to the Indo-European language family). Little is known about the Slavs before they are mentioned in Byzantine records of the 6th century CE, and most of what we know about them prior to this time is mainly derived from archaeological and linguistic studies. The Byzantine authors refer to the Slavs as "Sclaveni".
