The title "Lord of Meath" refers to a historical noble title in Ireland, specifically associated with the province of Leinster. The title was established in the 12th century and was held by various families, most notably the de Lacy family. The Lord of Meath had significant authority over the region, which included both political and judicial powers. The title was part of the broader feudal system introduced by the Anglo-Normans in Ireland. Over time, the importance of the title diminished, especially after the English Reformation and the subsequent changes in land ownership. Today, the title is largely ceremonial and is not associated with any governing authority.
