Roman law is the legal system of ancient Rome, including the legal developments spanning over a thousand years of jurisprudence, from the Twelve Tables (c. 449 BC), to the Corpus Juris Civilis (AD 529) ordered by Eastern Roman emperor Justinian I.
Roman law also denoted the legal system applied in most of Western Europe until the end of the 18th century. In Germany, Roman law practice remained in place longer under the Holy Roman Empire (963–1806). Roman law thus served as a basis for legal practice throughout Western continental Europe, as well as in most former colonies of these European nations, including Latin America, and also in Ethiopia.
