Common law refers to law developed by judges through decisions of courts that are called precedent.
Roman law, or civil law, differs from common law in that it is based solely on a legal code instead of precedent.
Its foundation is based not on English common law but on Roman Law and a mixture of French, German and Spanish law instead.
If you mean unite the many different citizens of the Roma republic it was law and language.
It is important to know the different laws of the different times. Roman law is the law code of ancient Rome. It forms the basis of civil law in many different countries today.
English common law & the Roman Civil law
Common law is a legal system derived from judicial decisions and precedent, where courts interpret and apply the law. Roman law, on the other hand, was a legal system developed in ancient Rome based on written statutes and codes. Common law relies heavily on precedent, while Roman law emphasized codification and abstract legal principles.
They are very similar with very different avenues for implementation. This is not intended to be a full answer but to replace the terrible answer that was here before. Essentially, both rely on statutory law as well as precedent. From my understanding, common law, which originally was all precedent based, lays out a requirement forcing subsequent cases that are the same as previously rendered cases to be judged with basically the same outcome. In America, this is only relevant to similar cases in the same or subservient courts. Please correct wherever I'm wrong, to fully understand this requires months of legal study.
The Justinian code was actually called Corpus Juris Civilis (Body of Civil Law). It codified Roman civil law. Roman civil law has provided the foundation of the civil many modern countries. It has done so by providing important principles of law. The actual laws of the time of Justinian I are not used as they applied to an ancient and very different world. The law of the US is based on common law, not civil law.

The English Common Law was important in the development of the American System of Criminal Justice System. Th English Common Law was chosen by the judges and courts. The English Common Law provides presidential weight on the common law and requires that all acts committed be treated the same and not different on different occasions.
Roman citizens, like us, did not have the right to commit crime or treason or to murder, which were punishable. Apart from this, the rights of Roman citizens were similar to ours as Roman civil law established principles of rights which provided the foundation of the rights under modern civil law and modern common law.
No, the Romans used Roman law and governed according to Roman custom. That's why it's called an empire.
