A Landgrave is a noble title historically used in parts of Europe, particularly in the Holy Roman Empire and later in Germany. The title signifies a rank above a count but below a duke, often governing a specific territory known as a landgraviate. Landgraves had significant authority over their lands, including judicial and administrative powers. The title was most notably associated with regions like Hesse and Thuringia. Landgraves played a crucial role in the feudal system, managing lands and serving the emperor. Over time, the title has become largely ceremonial, with modern equivalents existing in some European countries.
