The Germanic Peoples
Europe’s northernmost Indo-Europeans are thought to have originated in Southern Scandinavia and Northern Germany during the first millennium BC from a mix of indigenous Northern Europeans and semi-nomadic Horse Riders from the Eurasian steppe.
The Celtic Peoples
The ancestors of the Celtic peoples are identified with the Iron Age Hallstatt Culture, located in and around modern Austria, Switzerland and Southern Germany. From there they spread throughout much of Europe, including the British Isles, Western and Central Europe, the Balkans and even Anatolia.
The Hellenic People
Differing from the other Indo-European groups the Hellenics are actually only one people, at least in the modern sense: The Greeks, although it would take several millennia for them to unite as one. Ancient Greece was divided into several City States with varying degrees of power. There is reason to believe that the Greeks were heavily influenced by the indigenous or “Old Europeans” in terms of language, culture, mythology and even genetics.
The Italic Peoples
When we think of Italy and its history we think of the Roman Empire. But before Rome rose to power the Romans (or Latins) were only one among many closely related Italic peoples inhabiting the Appenine Peninsula, most famous among them the Samnites and the Sabines, but also non-Indo-European peoples such as the Etruscans.
The Indic Peoples
Some of the most ancient texts in any Indo-European language come down to us from the ancient Indic peoples known as the Indo-Aryans. In their sacred language, Sanskrit, they documented some of the earliest myths and legends about Indo-European gods and how to worship them.
