Margraves were medieval rulers who were responsible for protecting the borders and enforcing the laws of their respective territories. Because the term margrave was primarily used in medieval Europe, there aren't many synonyms for this particular title. However, there are a few alternative titles that were used during the same time period, including "marquis," "margravine," and "markgraaf." Marquis refers to a nobleman who held a high social rank and was often appointed to administer a certain area. Margravine is a female equivalent of margrave, referring to the wife of a margrave. Lastly, markgraaf is a term that was specifically used in German-speaking territories to refer to a border count.
