The principal administrative division in Maltropia below the national level is the principality (Irish: prionsacht, pl. prionsachtaí). Maltropia is divided into twenty-four principalities, of which sixteen are in mainland Maltropia and eight are in the Maltropian Islands.
Principalities - that is, hereditary lordships with fixed power bases larger than tribal chieftaincies and smaller than the medieval kingdoms of Espin and the Uí Chairbre and Uí Midire - first emerged in Maltropia's late fourth century, as the more powerful local lords in the north and east began to extend their reach with the proliferation of hill forts through which they subjugated their weaker neighbours. These lordships gradually evolved into feudal principalities over the following centuries, acquiring fixed territorial borders rather than shifting spheres of influence associated with the patron-client and overlord systems.
The title associated with the rulers of these states is flaith, now almost invariably translated as 'prince' (or 'chief') despite having a much broader meaning extending to the concept of sovereignty itself. Although the word prionsacht is used for principalities, the princes themselves are flatha.
The modern principalities of Maltropia do not entirely correspond to the states for which they are named, nor to the grade of those states' rulers. Carbery, Tyrmidra and Espin were once each ruled by a lord classed as a ruirí or rí ruirech; this ruler was demoted after submitting to the King of Maltropia between the 17th and 19th centuries. Minor lordships were promoted to the same status as former kingdoms, which contributed to the outbreak of the War of the Kings and Princes in 1737. With the elevation of the Maltropian Islands to equal status with mainland Maltropia in 1801, its eight baronies were also elevated to principality status, and the 1844 Treaty of Taralanos integrated the formerly-independent Kingdom of Espin into Maltropia as its twenty-fourth principality.
