What nationalities were there in ancient Europe?

There were three main nationalities in ancient Europe.

(1) Germanic:

In the late Roman Empire, the Germans had formed several branches, such as East Goth, West Goth, Frank, Burgundy, Vandal, Angles, Saxony, Norman and so on. (and of course some twigs)

(2) Slavic:

Slavs are divided into the following three branches:

Slavs in the west-Poles, Czechs, Slovaks.

B Yugoslavs-Bulgarians (the integration of Bulgarians and Slavs in Turkey), Serbs, Montenegrins, Macedonians, Croats, Slovenes and BiH.

C Eastern Slavs-divided into Russians, Ukrainians and Belarusians.

A relatively pure Celtic-Scots and Irish. In fact, they have also merged into a considerable Germanic component.

B French, Belgian Walloons (French-speaking) and Luxemburg are of Celtic origin.

Other important ethnic groups:

Hungarians: Also known as magyars, mainly the nomadic tribes of Madzar (near Turkic) who came from Central Asia and North Asia to settle in the Danube Plain in the 9th century, merged some descendants of Germans, Slavs and Huns who had already lived here to form Hungarians.

Finns: They are close relatives of magyars, but they have absorbed too many Germanic Normans, which has been seriously Germanized. From the outside, they don't see any difference from the Germans.
