The Aryans were Indo-Europeans who migrated from Central Asia through Iran to the Indus River Valley around 1500 BCE. They were a nomadic and warlike people. The Aryans rode into town on chariots and horses, which are native to the steppes of Central Asia. By about 800 BCE, they'd made their way to the Ganges River, using weapons of iron to conquer more and more territory. Many of the Aryans settled around the Ganges. They brought their culture and their language, known as Sanskrit, as well as their gods and early Hinduism. They also brought their social hierarchy, known as the caste system.
