The Germanic Branch
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 Branch
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 Branch
It is unclear whether there once were more members to this branch; All that is certain, is that today, there is only one Left: The Greeks. 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 Branch
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, which do not belong to the Indo-European language family, however.
The Indo-Aryan Branch
Some of the most ancient texts in any Indo-European language were passed down for generations from the Indo-Aryans. In their sacred language, Sanskrit, they documented some of the earliest myths and legends concerning an Indo-European religion and ritual practices.
