Why is 1500 BC to 322 BC known as the Vedic Age of India history?

The period from 1500 BC to 322 BC is known as the Vedic Age in Indian history due to the composition and development of the Vedas, the oldest sacred texts of Hinduism. This era marks the arrival of the Indo-Aryans, who established social, religious, and cultural systems that significantly influenced Indian society. It is characterized by the formulation of various philosophies, rituals, and the Caste System, laying the foundation for later developments in Indian culture and spirituality. The Vedic Age ultimately set the stage for subsequent historical periods, including the rise of the Maurya Empire.
