A "Mormaer" was a title used in medieval Scotland, equivalent to a regional lord or noble. The term is derived from the Gaelic word "mormaer," which means "great steward." Mormaers were responsible for governing specific territories, known as "mormaerdoms," and played a crucial role in the feudal system, managing lands and overseeing local justice. Mormaers often held significant power and influence, sometimes rivaling that of the Scottish king. They were typically granted their titles by the crown and were expected to provide military support. Notable mormaers included Mormaer of Fife and Mormaer of Angus, who were key figures in Scottish history.
