PLEASE HELP ME!! NO LINKS. which group of people controlled a large portion of eastern europe and spoke a language that most eastern europeans continue to use?

Slavs

Explanation:

The Slavs are an Indo-European people whose origin lies in Eastern Europe. They became the dominant group of people in Eastern Europe shortly after the fall of the Roman Empire, although they had to share and compete for this land with other groups like the Magyars, the Baltic Peoples, and the Finno-Ugric Peoples.

The Slavs have several subgroups, essentially East Slavs: Russians, Ukrainians, Byelorussians, West Slavs: Poles, Czech, Slovaks, and South Slavs: Serbs, Bosnians, Croats, Slovenes, Montenegrins, Macedonians, and Bulgarians.
