Which of the following accomplishments is associated with the Byzantine Empire?

The codification of Roman law known as the Justinian Code is a significant accomplishment associated with the Byzantine Empire. This legal code was established under the reign of Emperor Justinian I in the 6th century and served to consolidate and organize the vast array of existing Roman laws and legal principles into a coherent legal framework. The Justinian Code had a lasting influence on the development of legal systems in many European countries and is a foundational element of civil law traditions.

This accomplishment stands out because it demonstrates the Byzantine Empire's role as a critical custodian of Roman heritage and its influence on future European legal thought. The legal principles laid out in the Justinian Code provided clarity and consistency in law, impacting the administration of justice not only in the Byzantine Empire but also in many subsequent legal traditions throughout history.
