Final answer:
Rome's legacy in law and justice is significant due to its lasting influence on European legal systems, pioneering principles like the use of precedent and the notion of innocence until proven guilty, and its comprehensive legal code, the Corpus Juris Civilis, which became a model for subsequent legal frameworks.
Step-by-step explanation:
A commitment to law and justice may be considered Rome's greatest legacy because it laid the foundation for most legal systems in use in Europe today, except for Britain. The Romans introduced several groundbreaking legal principles, such as using precedent in legal decisions, the concept of innocent until proven guilty, and the development of both private and public law. They also extended Roman law to all free men and women in the empire with the formation of the Corpus Juris Civilis, which continued to influence law throughout history.
This legal framework not only served Rome but it also set a benchmark for legal fairness and administration that persisted through the centuries, influencing laws and legal practices across western society. Historical documents like the Twelve Tables and figures such as Sir William Blackstone who later promoted the Rule of Law, demonstrate the lasting impact of Roman legal concepts.
