WHAT GROUP OF PEOPLE ENTERED INDIA ONCE THE HARAPPAN CIVILIZATION DECLINED?

After the decline of the Harappan Civilization around 1900 BCE, the Indo-Aryans, a group of nomadic pastoralists, entered India. They are believed to have migrated from Central Asia and brought with them the Vedic culture, which significantly influenced the region's social, religious, and linguistic development. This transition marked the beginning of what is often referred to as the Vedic period in Indian history.
