The Justinian’s Code contains imperial constitutions, which are included in the codes of Gregorian and Theodosius and are still valid until Justinian, supplemented by later novels and modified according to the needs of the time. The Justinian’s Code consists of 12 books, books, in turn, consist of titles, titles are divided to individual imperial decrees.


The Justinian’s Code was divided into 12 books in the oldest and only unified code of Roman law. With the new editions of the decrees, the first task was to establish strict unity and consistent implementation of the principles. Justinian specifically emphasized the idea that none of the articles of the new code should contradict the other.

To this end, referring to the supremacy of imperial power, Justinian declared his right to eliminate and repeal the laws and regulations that had been in force before.

When the case was brought to an end, Justinian Code’s impact was that it announced the entry into force of the new code by decree of 529 addressed to the prefect of the praetorium, whose duty he was entrusted with sending the text of the code to all the provinces and announcing to all emperor subjects that it came into effect.

Books are further divided into 98 titles, and also the titles are further divided into fragments. Within the title of the constitution, units are arranged in chronological order and they are numbered. At the beginning of each constitution is indicated the name of the emperor who issued it, and the name of the person to whom it is addressed, that is, an inscription. At the end of each unit is the date of publication of the constitution, that is, the so-called subscription.
