A more thorough explanation:

Comparative legal history is a type of comparative law that aims to establish a universal history of law. It helps us understand how social phenomena have influenced the evolution of the legal world.

This field is closely related to other areas of study such as ethnological jurisprudence, folklore, legal sociology, and jurisprudence.

For example, comparative legal history can help us understand how the legal systems of different countries have evolved over time. By comparing the legal systems of ancient civilizations like Greece and Rome, we can see how their laws influenced the development of modern legal systems.

Another example is the study of the common law system in England and how it has influenced the legal systems of other countries like the United States and Canada.

Overall, comparative legal history helps us understand the historical and cultural context of different legal systems and how they have evolved over time.
