Landgrave (Dutch: landgraaf, German: Landgraf; Swedish: lantgreve, French: landgrave; Latin: comes magnus, comes patriae, comes provinciae, comes terrae, comes principalis, lantgravius) was a noble title used in the Holy Roman Empire, and later on in its former territories. The German titles of Landgraf, Markgraf ("margrave"), and Pfalzgraf bei Rhein ("count palatine [of the Rhine]") are in the same class of ranks as Herzog ("duke") and above the rank of a Graf ("count").
The English word landgrave is the equivalent of the German Landgraf, a compound of the words Land and Graf (German: count).
The title referred originally to a count who had imperial immediacy, or feudal duty owed directly to the Holy Roman Emperor. His jurisdiction stretched over a sometimes quite considerable territory, which was not subservient to an intermediate power, such as a Duke, a Bishop or Count Palatine. The title survived from the times of the Holy Roman Empire (first records in Lower Lotharingia from 1086 on: Henry III, Count of Louvain, as landgrave of Brabant). By definition, a landgrave exercised sovereign rights. His decision-making power was comparable to that of a Duke.
