The important branches in all early systems of jurisprudence are few in number. Of the many subjects into which the law is divided at the present time, some were entirely unknown, others were of slight importance. The oldest branches of the law under most systems were the laws governing Domestic Relations, and a combination of Criminal Law and Torts. The law of Real Property arose early in the agricultural stage of the economic development of a race; while, on the other hand, the law of personal property and of contracts were late in making their appearance.
