Provinces of Ireland
Since the early 17th century, there have been four Provinces of Ireland: Connacht, Leinster, Munster, and Ulster. The Irish word for this territorial division, cúige, meaning "fifth part", indicates that there were once five; however, in the medieval period there were more. The number of provinces and their delimitation fluctuated until 1610, when they were permanently set by the English administration of James I. The provinces of Ireland no longer serve administrative or political purposes but function as historical and cultural entities.
