THE Vedas are a collection of hymns and other ancient religious texts written in India between about 1500 and 1000 BCE. It includes elements such as liturgical material as well as mythological accounts, poems, prayers, and formulas considered to be sacred by the Vedic religion.
The origin of the Vedas can be traced back as far as 1500 BCE, when a large group of nomads called the Aryans, coming from central Asia, crossed the Hindu Kush Mountains, migrating into the Indian subcontinent. This was a large migration and used to be seen as an invasion. This invasion hypothesis, however, is not unanimously accepted by scholars today. All we know for certain, mainly through linguistic studies, is that the Aryan language gained ascendancy over the local languages in the Indian sub-continent. The language of the Vedas is Sanskrit, an ancestor of most of the modern languages spoken today in South Asia.
