Who were the Aryans and how might they have come to India?

The Aryans were a group of Indo-European nomadic tribes who are believed to have migrated into the Indian subcontinent around 1500 BCE. They are associated with the development of early Vedic culture and the Sanskrit language. Theories suggest they may have come through the northwestern passes of the Himalayas, possibly driven by factors such as climate change, seeking new pastures for their cattle. Their arrival and settlement marked a significant cultural and linguistic shift in the region, influencing the social and religious landscape of ancient India.
