Romans, who made no more distinction between elder and younger, between male and female, in the inheritance of lands, than we do in the distribution of moveables. But when land was considered as the means, not of subsistence merely, but of power and protection, it was thought better that it should descend undivided to one. In those disorderly times, every great landlord was a sort of petty prince. His tenants were his subjects. He was their judge, and in some respects their legislator in peace, and their leader in war. He made war according to his own discretion, frequently against his neighbours, and sometimes against his sovereign. The security of a landed estate, therefore, the protection which its owner could afford to those who dwelt on it, depended upon its greatness. To divide it was to ruin it, and to expose every part of it to be oppressed and swallowed up by the incursions of its neighbours. The law of primogeniture, therefore, came to take place, not immediately, indeed, but in process of time, in the succession of landed estates, for the same reason that it has generally taken place in that of monarchies, though not always at their first institution. That the power, and consequently the security of the monarchy, may not be weakened by division, it must descend entire to one of the children. To which of them so important a preference shall be given, must be determined by some general rule, founded not upon the doubtful distinctions of personal merit, but upon some plain and evident difference which can admit of no dispute. Among the children of the same family, there can be no indisputable difference but that of sex, and that of age. The male sex is universally preferred to the female; and when all other things are equal, the elder everywhere takes place of the younger. Hence the origin of the right of primogeniture, and of what is called lineal succession.
Laws frequently continue in force long after the circumstances, which first gave occasion to them, and which could alone render them reasonable, are no more. In the present state of Europe, the proprietor of a single acre of land is as perfectly secure of his possession as the proprietor of a hundred thousand. The right of primogeniture, however,
