Their rights were dormant in respect of exercise, simply because the unity of the household demanded that it should be governed by a single representative; but when the master of the household died, his sons at once came forward as its masters and now obtained on their own account over the women and children and property the rights hitherto exercised over these by the father.

On the other hand the death of the master occasioned no change in the legal position of the slave.
Family and Clan (-Gens-) So strongly was the unity of the family realized, that even the death of the master of the house did not entirely dissolve it.
The descendants, who were rendered by that occurrence independent, regarded themselves as still in many respects an unity; a principle which was made use of in arranging the succession of heirs and in many other relations, but especially in regulating the position of the widow and unmarried daughters.

As according to the older Roman view a woman was not capable of having power either over others or over herself, the power over her, or, as it was in this case more mildly expressed, the "guardianship" (-tutela-) remained with the house to which she belonged, and was now exercised in the room of the deceased house-master by the whole of the nearest male members of the family; ordinarily, therefore, by sons over their mother and by brothers over their sisters.

In this sense the family, once founded, endured unchanged till the male stock of its founder died out; only the bond of connection must of course have become practically more lax from generation to generation, until at length it became impossible to prove the original unity.

On this, and on this alone, rested the distinction between family and clan, or, according to the Roman expression, between -agnati- and -gentiles-.
