How many counties in the Republic of Ireland.

The Republic of Ireland has 26 counties because it was divided into counties during the 19th century administrative reforms. This division was based on historical and territorial considerations, as well as population distribution. The 26 counties include regions like Dublin, Cork, Galway, and Donegal, each with its own local government and administrative structure. The division into counties has been maintained to this day, helping facilitate governance and various administrative functions across the country.
