The Vedic Period is distinguished by the Indo-Aryan culture which was associated with the texts of Vedas, sacred to Hindus, and that were orally composed in Vedic Sanskrit. The Vedas are some of the oldest extant texts, next to those in Egypt and Mesopotamia. The Vedic era in the subcontinent lasted from about 1500-500 BCE, laying down the foundation of Hinduism and other cultural dimensions of early Indian society. The Aryans laid down Vedic civilization all over North India, particularly in the Gangetic Plain.
