Romanlaw, the law of ancient Rome from the time of the founding of the city in 753 BCE until the fall of the Western Empire in the 5th century CE. It remained in use in the Eastern, or Byzantine, Empire until 1453. As a legal system, Roman law has affected the development of law in most of Western civilization as well as in parts of the East. It forms the basis for the law codes of most countries of continental Europe (see civil law) and derivative systems elsewhere.
