Could slaves become citizens in Athens and Rome?

Yes they could have became citizens of Rome and Athens because the law changed sooner than later.

Explanation:

That law was relaxed as well as time went on; for example, children of freed slaves could apply to become citizens. Even if both parents were Roman citizens, children had no rights. Boys of Roman citizens went though a ceremony when they were 16 or 17, depending upon how close their birthday was to March 17th, and at that time became citizens of Rome with full benefits.

states began imposing duties on each other's goods. congress had no way to raise money for an army to expel them.
