The last veda called the Atharva Veda is a collection of magic spells and charms to ward off the evil spirits and diseases. It is considered a non-Aryan work and is the latest addition to the Vedas in later Vedic age.
The Satavahanas dynasty is also known in history for starting the practice of giving royal grants of land. These royal grants were given to Brahmanas and Buddhist monks, including those associated with tax exemptions.
