Like most emperors, Justinian I (or the Great) reformed the law by issuing new edicts - laws by imperial decree. However, what he is famous for is his collecting of centuries of Roman civil law in a single book (previously laws had been written on scrolls). This was the Corpus Juris Civilis (Body of Civil law) which was later also called the Justinian Code. This was a digest of centuries of Roman civil law and gave a uniform organisation to the law, scrapped obsolete enactments and redefined obscure passages, thus rationalising the law. It also included a collection of essays by famous jurists and a student textbook.

The Corpus Juris Civilis came in four parts.

1) The Codex (book) which was a review of imperial laws going back 400 years (to the time of Hadrian). It scrapped obsolete or unnecessary laws, made changes when necessary and clarified obscure passages. Its aim was to put the laws in a single book (previously they were written on many different scrolls), harmonise conflicting view among jurists which arose from centuries of poorly organised development of Roman law and have a coherent body of law. It consists of 12 books, 1 book covers ecclesiastical law, the duties of high officers and sources of law, 7 cover private law, 1 criminal law and 3 administrative laws.

2) The Digesta which was a collection of fragments taken from essays on laws written by jurists (mostly from the 2nd and 3rd centuries) and which expressed the private opinions of legal experts. Most were from Ulpian (40%) and Paulus (17%). It was a large amount of writing which was condensed in 50 books. It was used as an advanced law student textbook.

3) The Institutiones was a textbook for first year law students written by two professors. It was a series of extracts from statements on the basic institutions of Roman law from the teaching books by 'writers of authority.' In was largely based on the texts of Gaius, a jurist of the 2nd century AD.

4) The Novellae Constitutiones, which contained laws recently issued by Justinian.

The name Justinian Code was coined in the Middle Ages. Its actual name was the Corpus Juris Civilis (Body of Civil Law). This work was commissioned by Emperor Justinian I and comprised a digest of centuries of Roman civil law, a collection of essays on law and a textbook for students. It made Roman civil law more uniform and helped with the study of law. When it was rediscovered in a library in Pisa 1070 it became very influential. Roman civil law was so well developed that it is still the basis for the civil law of many modern countries thanks to its systematisation in this work.

The Corpus Juris Civilis (dubbed Justinian Code in the 16th century) did not contain any ideas of its own. It presented, among other things, parts of the works on law by important Roman jurists (law experts). Although Cicero occasionally explained some legal concepts, he was not a jurist. He was a rhetorician and a and moral philosopher. The Corpus Juris Civilis, which was compiled nearly 580 years after Cicero, did not draw anything from his work.

The Corpus Juris Civilis was a set of books which came in four parts. One, the codex, was a collection of extracts from 400 years of Roman laws which scrapped obsolete or unnecessary laws, made changes when necessary and clarified obscure passages. Its aim was to put the laws in a single book (previously they were written on many different scrolls), harmonise conflicting views among jurists which arose from centuries of poorly organised development of Roman law and have a uniform and coherent body of law.

Justinian promulgated several new laws, known as the Novellae. The Institutes, Digest, Code and Novels together comprise what is known as the Corpus Juris Civilis, the Body of Civil Law.

It was a code of laws that served as the foundation of international law that is still used today. The Justinian Code was very important because it was used as a fundamental law basis even in the U.S. today. It provided the laws on marriage, property, slaves, and other important issues.

Justinian I was emperor of the Byzantine Empire (the name given by historians to the eastern part of the Roman Empire after the fall of the western part) from 482 to 565. Historians see his reign as a distinct period of Byzantine history. It was a period of conquest, splendour, great prosperity, important public works, administrative and religious reforms and imperial unity.

The reign of Justinian I (or the Great) was one of prosperity. He set out to reconquer lands which the western part of the Roman Empire had lost with the Germanic invasions. He managed to retake north Africa, southern Spain and most of italy. This increased the imperial revenues by some 20%. Justinian used this to undertake many infrastructural projects. He built a dam is southwestern Turkey to prevent floods and the Sangiarius bridge in northwestern Turkey to secure a supply route to the east for the army. He built border fortifications from Africa to the East. Justinian restored towns damaged by an earthquake and built a new city, Justiniana Prima, as the new capital of the province of Illyria. He built a massive granary on an island near Constantinople to make the grain traffic form Egypt more efficient. He also established diplomatic relations with Ethiopia to bypass the land Silk Road through Persia because there were wars with Persia and managed to establish a local production of silk.

Justinian increased trade and prosperity but it has to be noted that this benefitted mostly the wealthy and the well-to-do. The poor jus remained poor.

Justinian's gains in prosperity were wiped out towards the end of his reign by one of the worst plagues in history. Historians have called it the Plague of Justinian.

Yes. Justinian I was emperors of the Byzantine Empire. Historians have coined this term to indicate the eastern part of the Roman Empire after the fall of the Roman Empire. The Romans did not use this term. They called Roman Empire.

The Corpus Juris Civilis (Body of Civil Law), which was later also called the Justinian Code was commissioned by Justinian I and was published in a second edition in 534. It came in four parts. 1) A Codex (book) which was a review which collected imperial laws going back 400 years (to the time of Hadrian, reigned 117-138 AD) into a single book. It scrapped obsolete or unnecessary laws, made changes when necessary,clarified obscure passages, and harmonised conflicting view among jurists which arose from centuries of poorly organised development of Roman law so as to have a coherent body of law. 2) The Digesta which was a collection of fragments taken from essays on laws written by jurists (mostly from the 2nd and 3rd centuries AD) and which expressed the private opinions of legal experts. It was an advanced student textbook. 3) The Institutiones was a textbook for first year a law student which was a series of extracts from statements on the basic institutions of Roman law from the teaching books by 'writers of authority.' In was largely based on the texts of Gaius, a jurist of the 2nd century AD. 4) The Novellae Constitutiones, which contained laws recently issued by Justinian.

The reign of Justinian I is seen as a distinct period of Byzantine history by historians. It was a period of conquest, splendour, great prosperity and important public works, and administrative and religious reforms andimperialunity.

Justinian I wanted to ‘restore’ the Roman Empire by reconquering the lands lost by the Western Roman Empire as a result of the Germanic invasions. He succeeded in defeating the Vandals in Africa, retaking this area, the Ostrogoths, retaking Italy, Sicily and Dalmatia (on the eastern coast of the Adriatic Sea) and the Visigoths in Spain, retaking southern Spain. This gave him control of the western Mediterranean. The large state revenues the conquests generated (they increased by 20%) helped him with an ambitious programme of church building and public works. He rebuilt the damaged Church of the Holy Apostles and the Hagia Sophia church in Constantinople, which were both badly damaged, and built the church of San Vitale in Ravenna (the centre of Byzantine rule in Italy). He built underground cisterns to secure water supply for Constantinople, including the massive Basilica Cistern (453 by 212 feet and 30 ft. high)). He built a dam is southwestern Turkey to prevent flood and the Sangiarius bridge in northwestern Turkey to secure a supply route to the east for the army. He built border fortifications from Africa to the East. Justinian restored towns damaged by an earthquake and built a new city, Justiniana Prima, as the new capital of the province of Illyria. He built a massive granary on an island near Constantinople to make the grain traffic form Egypt more efficient. He also established diplomatic relations with Ethiopia to bypass the land Silk Road through Persia because there were wars with Persia and managed to establish a local production of silk.

Justinian I took measures to tackle corruption in the provinces and made tax collection more efficient by increasing its professionalization. He protected the purity of the official church and persecuted dissident Christian sects and paganism. He secured the rights of the church and the clergy and protected and expanded the monastic orders. He granted the monks the right to inherit property from private individuals and to receive annual gits for the state of from taxes and banned the confiscation of monastic property. He gave the canons of the church legal force and issued laws regarding the administration of church property, the elections and rights and obligations of the clergy, the conduct of service and episcopal jurisdiction. Justinian I was one of the most important emperors in the history of the Orthodox Church. He described as a ‘nursing father’ of the church and put it on a more solid footing, and redefined its structure. Justinian’s rule was quite despotic. He regulated everything in administration, law and religion tightly. It was said that the church could do nothing contrary to his will.

Justinian I’s most enduring legacy was his commissioning of the Corpus Juris Civilis (Body of Civil law) which was later called the Justinian Code. This was a digest of centuries of Roman civil law and gave a uniform organisation this law, scrapped obsolete enactments and redefined obscure passages. It also included a collection of essays by famous jurists and a student textbook. The Corpus Juiris Civilis has provided the basis of the civil law of many modern countries.

Towards the end of his reign, the splendour and prosperity of his reign was undone by the outbreak of a major plague which decimated the population of the empire. Its impact has been compared to that of the Black Death in the Middle Ages.

The Justinian code is the collection of Roman law. These laws were collected in single volume by the Justinian, so due to this reason these laws are called Justinian laws. This volume was completed in 534 AD and now has effects on Western laws.

P.S.

Justinian's reign was marked by the ambitious (but ultimately failed) Renovatio Imperii, or "restoration of the empire". The achievement of this ambition came in the form of the partial recovery of the territories of the Western Roman Empire, including the city of Rome itself. He also rewrote Roman law, the 'Corpus Juris Civilis', which is still the basis of civil law in many modern states. His reign marked the blossoming of Byzantine culture, and his building program yielded such masterpieces as the church of Hagia Sophia in Constantinople, which became the center of Eastern Orthodox Christianity for many centuries. He outlawed all religions except Christianity, which he saw as the upcoming popular religion, and which he wanted to align himself with as a major supporter. He was very savvy about politics and the people, and he made sure he remained one step ahead of his enemies.
