Which code of laws compiled under Justinian became the foundation for European legal tradition?

• A. Corpus Juris Civilis
• B. Code of Justinian
• C. Justinian's Institutes
• D. Lex Romana

Answer: (A)

The big idea here is how a single, organized body of law can shape legal systems for centuries. The compilation established by Justinian—the Corpus Juris Civilis—does exactly that. It brought together imperial decrees, jurists’ writings, and a student-focused handbook into one coherent collection. By systematizing and preserving Roman law, it created a portable, teachable, and referenceable code that could be and was used across generations, especially as medieval scholars in Europe rediscovered and studied it. This enduring, comprehensive codification became the backbone of continental European civil law, influencing legal thought and practice long after the fall of the Western Roman Empire. The other terms are parts or later labels rather than the complete foundational codification. The Code of Justinian is essentially the Codex portion of the corpus, Justinian’s Institutes are the introductory textbook within it, and Lex Romana is a later medieval way of referring to Roman law in general rather than a direct, single compilation by Justinian.
