Although described as a legal fiction it was a direct consequence of the simple principle that a Roman could not be enslaved on Roman soil.

The patria potestas, indeed, existed in all its old rigour, and the power of life and death over the children still found occasional expression; but the unity of the family had been largely dissolved by the laxity of the marriage tie.
