Relating to a margrave, which is a nobleman of high rank in certain European countries, often responsible for border territories.
The margravial title was historically significant in the governance of the region.
Margravial → It is formed from "mark" (from Old High German *marca*, meaning border or boundary) and "gravius" (from Latin *gravius*, meaning count or nobleman). The term refers to a nobleman who governs a border territory, thus combining the concepts of a border and nobility.
Think of a nobleman ('gravius') who governs a border ('mark') — that's what margravial means.
