How was Aryan society different from Harappan society?

Harrapans resided mainly in north western india and were mainly agricultural whereas aryans succeeded harappans and had better weapons and also did farming. they spread all over india

The Aryans, a nomadic warrior, tribe migrated to the Indus valley around the time that the Harappan civilization went into decline. They were different races and so had different cultures, until they intermingled, giving rise to the Brahminic culture of ancient India
