When the byzantine emperor Justinian ns assumed preeminence in 527 ce, he uncovered the law of the Roman realm in a state of great confusion. It included two masses the were usually distinguished as old legislation and brand-new law.

Virgin mar (centre), Justinian i (left), holding a design of Hagia Sophia, and also Constantine ns (right), stop a model of the city that Constantinople, detail of a mosaic indigenous Hagia Sophia, 9th century.

The old law consisted of (1) all of the statutes passed under the republic and early empire that had actually not become obsolete; (2) the decrees that the Senate passed at the end of the republic and during the first two centuries of the empire; and (3) the writings of jurists and, much more particularly, that those jurists to whom the kings had given the best of heralding the legislation with their authority. These jurists, in their commentaries, had actually incorporated almost all that was that importance. Of these many records and writings the old law, numerous had come to be scarce or had actually been shed altogether, and also some were of hesitant authenticity. The whole mass of job-related was so costly to create that also the publicly libraries did no contain finish collections. Moreover, this writings included many inconsistencies.

The brand-new law, which included the ordinances that the kings promulgated during the middle and also later stages of the empire, was in a similarly disorganized condition. These ordinances or constitutions were very numerous and contradictory. Because no complete collection exist (earlier codices were no comprehensive), other ordinances had actually to be derived separately. It to be thus essential to collect right into a reasonable corpus as lot of the law, both brand-new and old, together was pertained to as binding and also to purge that contradictions and inconsistencies.

Immediately after ~ his accession, Justinian appointed a the supervisory board to resolve the imperial constitutions. The 10 commissioners walk through all of the constitutions that which copies existed, selected those that had practical value, cut all unnecessary matter, got rid of contradictions through omitting one or the other of the conflict passages, and adapted all the provisions to the scenarios of Justinian’s own time. The result Codex Constitutionum to be formally promulgated in 529, and also all royal ordinances not had in it to be repealed. This Codex has been lost, however a amendment edition the 534 exist as part of the so-called corpus Juris Civilis.

The success that this very first experiment encouraged the emperor to effort the more complicated enterprise the simplifying and also digesting the works of the jurists. Thus, start in 530, a brand-new commission of 16 eminent lawyers collection about this job of compiling, clarifying, simplifying, and ordering; the outcomes were released in 533 in 50 publications that came to be known together the Digest (Digesta) or Pandects (Pandectae). ~ enacting the Digest together a lawbook, Justinian repealed every one of the other law included in the treatises that the jurists and directed that those treatises have to never be cited in the future, also by method of illustration; at the very same time, the abrogated all of the statutes that had created a part of the old law. An overview of the facets of roman inn law called the academy of Justinian (or just Institutiones) was released at about the very same time.

Between 534 and also his death in 565, Justinian himself issued a an excellent number of ordinances the dealt with many subjects and also seriously altered the legislation on plenty of points. These ordinances are called, by way of distinction, brand-new constitutions (Novellae Constitutiones post Codicem); in English they are described as the Novels.

All of this books—the amendment Codex Constitutionum (the original job-related was revised four and also a half years later), the Digest, the Institutes, and also the Novels—are jointly known as the body Juris Civilis. This corpus Juris of Justinian, with a couple of additions native the ordinances of prospering emperors, ongoing to it is in the cook lawbook in what stayed of the roman inn world. In the 9th century a brand-new system known as the Basilica was all set by the emperor Leo through the Wise. The was created in Greek and consisted of parts of the Codex and also parts of the Digest, joined and also often changed in expression, in addition to some product from the Novels and imperial ordinances subsequent to those the Justinian. In the west provinces, the legislation as cleared up by Justinian hosted its ground.

Categories of roman law

The legislation of persons

“The main difference in the regulation of persons,” claimed the 2nd-century jurist Gaius, “is the all males are either free or slaves.” The slave was, in principle, a human being chattel who can be owned and also dealt v like any kind of other item of property. As such, he was not only at the mercy the his owner however rightless and also (apart native criminal law) dutiless. Also though the slave was in legislation a thing, he was in reality a man, and this modified the principle. A slave can not it is in a party to a contract nor very own property, yet he can be provided a de facto patrimony, which can be retained if he were freed; if he made a “commitment,” it might ultimately be enforced against his master. A manumitted slave became, in many instances, not only free but also a citizen.

The meaning of citizenship was necessary for the purposes of private legislation because certain parts applied only to citizens (jus civile). Noncitizens could be either Latini, occupants of Roman settlements that had actually the rights of members the the initial Latin League, or peregrini, that were members of foreign neighborhoods or of those areas governed but not soaked up by Rome. The great extension that the citizenship through the emperor Caracalla in 212 ce decreased the prestige of this part of the law.


The cook characteristic the the Roman family members was the patria potestas (paternal power in the kind of absolute authority), i beg your pardon the elder father exercised over his children and also over his more remote progeny in the male line, whatever their age could be, and also over those that were carried into the family members by adoption—a common practice at Rome. Initially this intended not just that he had control over his children, also to the best of inflicting funding punishment, however that that alone had any kind of rights in personal law. Thus, any kind of acquisitions do by a kid under potestas came to be the property of the father. The father could indeed allow a kid (as he could a slave) specific property to treat together his own, however in the eye that the regulation it ongoing to belong come the father.

By the first century ce there were already modifications of the system: the father’s power of life and death had shrunk to that of light chastisement, and the son might bind his dad by contract v a 3rd party within the exact same strict boundaries that applied to slaves and also their masters. Sons likewise could save as their very own what castle earned together soldiers and also even make wills of it. In Justinian’s day, the position concerning property had adjusted considerably. What the father provided to the child still remained, in law, the father’s property, yet the rules worrying the son’s own earnings had actually been expanded to numerous sorts of skilled earnings; and also in various other acquisitions (such as building inherited indigenous the mother), the father’s civil liberties were diminished to a life attention (usufruct). Normally, patria potestas ceased only with the fatality of the father; however the father might voluntarily complimentary the child by emancipation, and also a daughter end to it is in under her father’s potestas if she come under the manus of she husband.

There were two types of marriage known to the law, one v manus and also one without, however the manus form of marriage was rare even in the late republic and also had disappeared long prior to Justinian’s day. Manus was the autocratic power of the husband end the wife, matching to patria potestas over the sons.

Marriage without manus to be by much the an ext common in all effectively attested periods. It was formed (provided the next were over the period of puberty and, if under potestas, had their father’s consent) merely by beginning conjugal life v the intention of gift married, normally evidenced by the bringing of the bride to the bridegroom’s house. The wife stayed under she father’s potestas if he were still alive; if he to be dead, she continued (as lengthy as guardianship of ladies continued) to have actually the exact same guardian as before marriage. Both spouses had to it is in citizens, or if one was not, that or she must have conubium (the right, sometimes provided to non-Romans, that contracting a roman inn marriage). In marital relationship without manus, the property of the spouses remained distinct, and even gifts in between husband and also wife were invalid.

Divorce was permitted to the husband in early on Rome only on particular grounds. Later, divorce was always feasible at the circumstances of the husband in instances of marital relationship with manus; in marital relationship without manus, either party was free to placed an finish to the relationship. A officially letter to be usually given to the spouse, but any kind of manifestation of on purpose to finish the relationship—made clean to the various other party and accompanied by really parting—was all the was legit necessary. The Christian emperors applied penalties ~ above those who divorced without great reason, consisting of prohibitions ~ above remarriage, but the strength of the next to finish the marriage by their very own act was no taken away.

Concubinage was recognized in the realm as a “marriage” without a dowry, through a reduced status because that the woman, and also with provisions the the youngsters were no legally the father’s heirs. A man could not have actually both a wife and also a concubine. In the 4th century the emperor Constantine first enacted a law permitting the kids of together unions to be legitimated through the subsequent marital relationship of their parents. Medieval civil law extended this rule to all illegitimate children.

Persons under the age of puberty (14 because that males, 12 for females) needed tutores if lock were not under patria potestas. Together tutors might be appointed under the will of the father or masculine head that the household. Failing together an appointment, the guardianship walk to specific prescribed relatives; if there were no qualified relations, the magistrates appointed a tutor. Originally, kids were thought about adults at the age of puberty; but, after ~ a lengthy development, it came to be usual because that those between the periods of puberty and 25 to have actually guardians that were constantly magisterially appointed. Originally, all females not under patria potestas or manus also needed tutores, appointed in the same means as those because that children. By the early on empire, this provision to be little much more than a burdensome technicality, and also it disappeared native Justinian’s law.


The Romans did not build a generalized principle of juristic personality in the sense of an reality that had actually rights and duties. They had no terms because that a corporation or a legitimate person. Yet they go endow certain aggregations of persons with details powers and also capacities, and also the basic legal concept hovered between corporate powers, as understood in modern law, and powers enjoyed jointly by a group of individuals. The source of such cumulative powers, however, was always an plot of state.

Four species of corporation to be distinguished:

1. Municipia (the citizen body, originally composed the the dominated cities and also later of other local communities) possessed a corporateness the was known in together matters as having the strength to acquire things and also to contract. In imperial times, they to be accorded the strength to manumit slaves, take it legacies, and also finally—though this came to be general just in postclassical law—to it is in instituted as an heir.

2. The populus Romanus, or the “people the Rome,” collectively could get property, make contracts, and be appointed heir. Public property included the residential property of the treasury.

3. Collegia—numerous private associations with specialized functions, such together craft or profession guilds, funeral societies, and societies specialized to special spiritual worship—seem to have carried on their affairs and to have held residential property corporately in republican times. The emperors, city hall the collegia through some suspicion, enacted from the beginning that no collegium can be founded without state authority and that their rights of manumitting slaves and taking traditions be closely regulated.

4. Charitable funds ended up being a concern of postclassical law. Property might be donated or willed—normally, yet not necessarily, to a church—for part charitable use, and also the church would certainly then (or for this reason it appears from the evidence) have actually the duty the supervising the fund. Royal legislation managed the disposition of such funds so the they can not be supplied illegally. In such instances ownership is assumed to have actually been temporarily forgive in the administrators.
