Tethbae
middle Ages Irish confederation

Tethbae (Old Irish pronunciation: [ˈt̠ʲeθβe]; also spelled Tethba, often anglicised Teffia) was a confederation of túatha in central Ireland in the Middle Ages. It was divided into two distinct kingdoms, north Tethba, ruled by the Cenél Coirpri, and south Tethba, ruled by the Cenél Maini. It covered parts of County Westmeath and much of County Longford, counties which today are the far north-west part of the province of Leinster. In some cases, Tethbae may refer to South Tethbae only.
Two Tethbae
In Early Christian times, Tethba lay within the lands of the southern Uí Néill and the ruling dynasties of both kingdoms were reckoned members of the Uí Néill kindred in medieval genealogies. North Tethba—Tethbae Thúaiscirt—was centred on Granard, while south Tethba—Tethbae Deiscirt—lay around Ardagh.
The division of Tethbae into northern and southern regions was attested in the 7th century. It was not only a political and dynastic division. The chief churches of the two-halves belonged to different church confederations. North Tethbae's principal church at Granard was associated with Saint Patrick from the earliest written records.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Tethbae”, the useful work is to connect “middle Ages Irish confederation” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 21, 2026. The linked authority identifier is Q7706096. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
