Cattle rearing were an important economic activity for the Aryans, although they practiced agriculture. Cattle were considered wealth.  

• The term for war in the Rig Veda was gavishthi which means search for cows (which is the contemporary term (goshti) for factions as well).  
• The donations to the priests were mainly cows and women slaves but not land, which reveals the importance of pastoralism. There was no private property in land.
