Where did we learn most of what we know about Aryan history?

Most of what we know about Aryan history comes from a combination of archaeological findings and ancient texts, particularly the Vedic scriptures of India, which provide insights into the culture, society, and religious practices of the Indo-Aryans. Additionally, linguistic studies of Indo-European languages help trace their origins and migrations. Archaeological sites, such as those related to the Indus Valley Civilization and the subsequent Vedic period, also contribute to our understanding of their historical context. Lastly, historical accounts from neighboring cultures offer further perspectives on Aryan interactions and influences.
