Where did the Aryans come from and why?

Answer 1

The Aryans were organized into many tribes called Janas. Each Jana consisted of a number of villages called Gramas. A Grama was composed of a number of families. Each village was headed by a Gramani or the village headman. Each tribe had its own chieftain or Rajan.
Aryans came from Indo-Europeon

Answer 2

The word Aryan is an archaic term for either the proto-Indo-European people who are believed to have originated in central Russia, or the proto-Indo-Iranian people who originated in southern Russia.

As part of the mass migration of people over many thousands of years, proto-Indo-European people migrated westward into much of Europe, taking their language with them. Not all these people migrated westward, and a proto-Indo-Iranian culture developed in the south of Russia, probably around 2500 BCE. A few centuries later, a group migrated south-east into India, taking both language and the early Hindu religion with them. A later group also migrated south, to the east of the Caspian Sea, into eastern Iran, also taking language and the Zoroastrian religion. A third group migrated south, around the western edge of the Caspian Sea into western Iran. This last group, which was to become the Medes and Persians, took an older religion with them but converted, centuries later, to Zoroastrianism.
