1. One of the earliest systems of law of which we have knowledge is the collection of laws, known as the Code of Hammurabi the Babylonian king, who lived in about 1900 B.C., and whose stone figure we can see in the British Museum in London. Another early code is the code of Hebrew Law contained in the Book of Exodus in the Bible.
2. In Greece each city state had its own law, some laws were common to many states. In the seventh century B.C. the Greeks began to put their laws into Writing. About 594 B.C. Solon, the famous Athenian law-giver, provided a new code of law. The Athenians did not consider it necessary to have legal experts for non-criminal cases. In a civil case the verdict was given by a jury, which might number anything from 201 to 2,500. The members of the jury listened to speeches made by the persons who had brought the case before them, and by their friends. Barristers did not participate in court proceedings, but professional speech-writers sometimes prepared speeches.
3.Roman law is one of the greatest systems that has ever existed. It was based upon custom, and by A.D. 528 the quantity of Roman Law had become so immense that the Emperor Justinian in Constantinople ordered to make a clear, systematic code of all the laws.
4.Roman law had a deep influence upon the law of the world. It had a strong influence on the law of most European countries and some influence on Anglo-Saxon law, which is the other great law system of the world. After many years Roman law reapeared in the eleventh century, when there was a great revival of learning. Many European countries began to use Roman law in their courts. In France, however, until Napoleon codified the law in 1804, each province had its..own laws. The Napoleonic Code was a splendid achievement, and it has influenced the law of many countries in Europe and South America.
