Final answer:
The Harappan civilization was a single state with a strong central authority, possibly operating as a series of small republic-like states. The presence of similarly styled artifacts at Harappan sites suggests a common culture and organization.

The fact that the Harappan sites had similarly styled pottery, jewelry, toys, and tools suggests a common culture and organization.
