Leath Cuinn and Leath Moga
Leath Cuinn (Conn's Half) and Leath Moga (Mugh's half) refers to a legendary ancient division of Ireland.
Leath Cuinn was the island north of the Esker Riada (east-west drumlin belt from Dublin to Galway Bay). Conn Cétchathach, for whom this division is named, was a retrospective ancestor of the Connachta and Uí Néill dynasties.
Legendary origin of the term
- The North - taking in Connacht, Ulster and Meath - would be Conn's Half
- The South - taking in Munster, Osraighe and Leinster - would be Eoghan's Half.
The Eoganacht dynasty in Munster claimed, as descendants of Oiloill Olum, the historical right as overkings of Leath Moga (i.e. overlordship of Leinster as well as Munster) in the early medieval age, a claim disputed by the Ui Neill.
