History of the Slavic languages
The history of the Slavic languages stretches over 3000 years, from the point at which the ancestral Proto-Balto-Slavic language broke up (c. 1500 BC) into the modern-day Slavic languages which are today natively spoken in Eastern, Central and Southeastern Europe as well as parts of North Asia and Central Asia.
