March of Fermo

The March of Fermo (Latin: Marchia Fermana or Firmana, Italian: Marca fermana) was a frontier territory (march) of the Holy Roman Empire in the Kingdom of Italy between the late 10th and early 12th centuries. It faced the Principality of Benevento and later the Duchy of Apulia to the south. It covered part of the modern regions of Marche and Abruzzo.

The relationship of the March of Fermo to earlier administrative divisions is uncertain. By the 12th century it had been merged with the March of Ancona. The name continued in use to describe the province around Fermo and in this way formed one of the marches that gave the region of Marche its name.
