During this important period of Indian history, iron technology diffused, transforming and multiplying tools; cities arose and commerce spread; the caste system assumed practically all its essential features; powerful states were formed, with armies and bureaucracies; and, finally, Jainism and Buddhism brought about a veritable religious revolution."
