Landgrave:
Landgrave (German: Landgraf, Dutch: landgraaf, Swedish: lantgreve, French: landgrave; Latin: comes magnus, comes patriae, comes provinciae, comes terrae, comes principalis, lantgravius) was a rank of nobility used in the Holy Roman Empire, and its former territories. The German titles of Landgraf, Markgraf (“margrave“), and Pfalzgraf (“count palatine“) are of roughly equal rank, subordinate to Herzog (“duke”), and superior to the rank of a Graf (“count”).
