It is most likely that the people who influenced the Corpus Juris Civilis (Body of Civil Law, which was later dubbed Justinian Code) the most were Ulpian, Paulus and Gaius, three Roman jurists of the second century AD.

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 Justinian code was part of a wider collection of books which were called Corpus Juri Civilis (Body of Civil Law) which was commissioned by the emperor Justinian.It had four parts:

1) The Codex (book) Justinianus, 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 views among jurists which arose from centuries of poorly organised development of Roman law and have a uniform and coherent body of law. It consisted 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 is a collection of fragments taken from essays on laws written by jurists (mostly from the 2nd and 3rd centuries) which express the private opinions of legal experts.

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

The purpose of the Juris Civilis (Body of Civil Law), which was also dubbed Justinian Code in the 16th century, was to collect Roman law into books (code is derived from codex, the Latin word for bound book) to revise it and to provide law textbooks for law students. The emperor Justinian I commissioned this collection of books. A first edition was published in 529 and a second one in 534.

After Caesar's assassination, Cleopatra met Mark Antony and fell in love with him. They got married. As a gift to Cleopatra, Antony gave her the library of Pergamum, which was a city not far from Alexandria. Weigall (341) notes that it contained 200,000 roles, not nearly as much as the library of Alexandria had been, but it was still a gift that she loved.

Justinian I commissioned a collection of books called Corpus Juris Civilis (Body of Civil Law), which was also dubbed Justinian Code in the 16th century. A first edition was published in 529 and a second one in 534. It was a very comprehensive digest of centuries of Roman civil law which revised the whole of Roman law. It also included collections of essays by famous Roman jurists in two student textbooks. It has provided the basis of the civil law of many modern countries.

The importance of the Corpus Juris Civilis (Body of Civil Law) also nicknamed the Justinian code,to the Romans is not known. There is not any ancient writing about its importance of effect back then. It became very important to Europeans after a copy was rediscovered in a library in Pisa in 1070. In became the basis for law degrees in many universities. It also led to Roman law providing the foundation for the civil laws of many modern countries.

The Romans had more than one legal code over the 1,200 years (in the western part of the Roman Empire) and 1,500 year (in the eastern part of the Roman Empire) of their history. The most comprehensive and famous one is the Corpus Juris Civilis.which was also dubbed the Justinian Code in the 16th century.It was the first truly comprehensive compendium of Roman laws. It was commissioned by the emperor Justinian I (or the Great, reigned 527-565). A first edition was published in 529 and a second one in 534. It came in four parts:

1) The Codex (book) or Codex Justinianus, which was a review of imperial laws going back 400 years (to the time of Hadrian).

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

Justinian I (or the Great) was an emperor of the Roman Empire. This empire from the late 5th century onward is usually called Byzantine Empire. This is a term which has been coined by historians who use it to indicate the eastern part of the Roman Empire after the fall of the western part. However, the so-called "Byzantines" did not use this term. They said Roman Empire, or Romania (which did not refer to the modern day country).

Justinian I commissioned the Corpus Juris Civilis (Body of Civil Law), which was also dubbed the Justinian Code in the 16th century. A first edition was published in 529 and a second one in 534. It was the largest compendium of Roman civil law and came in four parts:

1) The Codex (book) or Codex Justinianus, 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.

The actual importance of the Corpus Juris Civilis (Body of Civil Law), which was later also called the Justinian Code, and which was commissioned by Justinian I and was published in a second edition in 534 is unknown. There is no historical record of the its impact at the time.

This work was forgotten after the fall of the Roman Empire until it was discovered in a library in Pisa in 1070. It had a big impact because many people were impressed with the key principles of Roman civil law: citizenship and citizenship rights, equality under the law, the right to a trial and the right to appeal, innocent until proven guilty, that the burden of proof rest on the accuser and not on the accused, and that an unfair law can be repealed. Eventually, though this work, Roman civil law became the foundation of the civil laws of many modern countries.
