Dál nAraidi was centered on the northern shores of Lough Neagh in southern County Antrim. Dál nAraidi was one of the more prominent sub-kingdoms of Ulaid, with its kings contending with the Dál Fiatach for the over-kingship of the province for some centuries.
To the north of Dál nAraidi in County Antrim lay the Dál Riata, the boundary between which was marked out by the River Bush to Dál Riata's west, and the southern boundary running from Ravel Water to just north of Glynn on the east Antrim coast.
In the mid-7th century the Dál nAraidi of Magh Line, ruled by the Uí Chóelbad dynasty, conquered Eilne (alias Mag Eilne) to their north-west and a branch of their dynasty seems to have settled there. This branch of the Uí Chóelbad descended from Fiachra Cáech (d. 608), brother of Fiachnae Lurgan, king of Dál nAraidi and over-king of Ulaid.
Dungal Eilni, great-grandson of Fiachra Cáech and king of Dál nAraidi, was possibly the first of this branch to be based in Eilne, however in 681 was killed at Dún Ceithern (modern-day Giant's Sconce in parish of Dunboe, west of River Bann). This branch of the Magh Line Dál nAraidi eventually became known as the Dál nAraidi in Tuaiscirt (Dál nAraidi of the North) and Dál nAraidi Mag nEilne. The first reference to Dál nAraidi in Tuaiscirt can be found in the Annals of Ulster under the year 824.
Between 646 and 792, the Dál nAraidi in Tuaiscirt held the overkingship of Dál nAraidi seven times, with two of that number becoming overkings of Ulaid.Cathussach mac Ailello, king of Eilne and Dál nAraidi, and claimed as having ruled the over-kingdom of Ulaid for sixteen years, was killed at Ráith Beithech (Rathveagh, County Antrim) in 749. Eochaid mac Bressal, who died in 832, was the last known king of the Dál nAraidi in Tuaiscirt to hold the over-kingship of the Dál nAraidi. The last known king of Dál nAraidi in Tuaiscirt is recorded in 883.
The Airgíallan dynasty of Uí Tuirtrí that lay west of the River Bann had been active east of it from as early as 776, and by the 10th century had taken control of Eilne.
Dál nAraidi in Tuaiscirt is said to have corresponded to the later baronies of Dunluce Lower and North East Liberties of Coleraine, and appears to correspond to the trícha cét of An Tuaiscert. It also became an Anglo-Norman cantred called Twescard, which later would absorb the cantred of Dalrede (based on Dál Riata), with these two combined cantreds forming the basis for the rural deanery of Twescard. A sub-division of in Tuaiscirt called Cuil an Tuaiscirt, meaning the "nook/corner" of Dál nAraidi in Tuaiscirt, was located in the north-west of the petty-kingdom near Coleraine. Its territory would form the basis of the later barony of North East Liberties of Coleraine.
The Dál nAraidi Magh Line, or the Dál nAraidi of Moylinny (modern-Irish Maigh Line, meaning "plain of Line") was the predominant dynasty of the Dál nAraidi. It was centered in southern County Antrim, with Ráith Mór its royal seat. In the 10th century they are counted as one of twelve tuatha of Ulaid. Line may represent the name of an original population grouping. It was also known as Mocu Aridi.
Their territory at its height spanned southern County Antrim and northern County Down containing the tuatha of Magh Line, Dál mBuinne, and Dál Sailni. It was later known as Trian Congaill, meaning the "third of Congal Claen" (Caech), and became an alias for the territory of Clandeboye, named as such after the Clandeboye O'Neill's who conquered the area in the late 14th century. By the 10th century Dál mBuinne was counted amongst the twelve tuatha of Ulaid. After the Viking era, Dál Sailni and its church at Connor, the principal church of Dál nAraidi was lost to the encroaching Uí Tuirtri.
The royal seat of the Dál nAraidi Magh Line was Ráith Mór (meaning "great fort", Anglicised as Rathmore), located near Lough Neagh in the civil parish of Donegore. It is first recorded in the Annals of the Four Masters under the date 680 as Ratha moiré Maighe Line. Neighbouring Ráith Mór was Ráith Beag (meaning "little fort", Anglicised as Rathbeg), and is attested location where Áed Dub mac Suibni, king of Dál nAraidi and Ulaid, killed High King Diarmait mac Cerbaill in 565. By the 16th century Ráith Mór became known as Ráth Mór Mag Ullin, meaning "great fort of the MacQuillans", and was burnt to the ground by Art mac Hugh O'Neill in 1513 after which it was never restored.
Cráeb Telcha, usually linked to modern-day Crew Hill near Glenavy, was the inauguration site of the Dál Fiatach kings of Ulaid, however it appears to have also been the same for the Dál nAraidi prior to the 9th-century contraction of their territory.
Magh Cobo (Uí Echach Cobo)
By the late 8th century, Dál Fiatach expansion had cut off the County Antrim and Down branches of the Cruthin from each other. As a result, the County Down branch consolidated into the kingdom of the Uí Echach Cobo, based at Magh Cobo, "the plain of Cobo". They were styled as kings of Cuib. According to the medieval genealogies they are descended from the Dál nAraidi, though this link is tenuous. By the 10th century Uí Echach Cobo was counted amongst the twelve tuatha of Ulaid.
Uí Echach Cobo's territory formed the basis of the medieval deanery and Norman cantred of Oveh, as well as the diocese of Dromore. Their territory was later Anglicised as Iveagh. Their 14th-century expansion formed the basis for the later barony of Iveagh.
Uí Erca Céin
Also spelt as Uí Dercco Céin and Uí Dearca Chein, the Uí Erca Céin where a branch of the Dál nAraidi, and according to the 10th-century Lebor na Cert, one of the twelve minor principalities under the king of Ulaid. They appear to have been based near Semne in Latharna, with their base possibly being Carrickfergus, and a list of Uí Erca Céin kings are given as having ruled Latharna until the mid-7th century, though there are records of kings down to around 900 AD. A branch of the Uí Erca Céin line of kings, the Síl Fingín, also twice held the overkingship of Dál nAraidi. After 750, the Uí Erca Céin became associated with the church of Bangor.
At some point they disappear from Latharna and by the 14th century are found in the territory of Leath Cathail in central County Down.
The Uí Erca Céin had five vassal tribes all of different origins: the Cenél Talain and Dál Fhocha nUchtar, both of whom appear to also have been of the Cruthin, and possibly refugees driven from their home that went to "Dercco Chen". A tradition of the Cenél Talain mentions that they had an ancestor who fought alongside Fiacha Araide, the eponymous ancestor of the Dál nAraidi; the Crothraidi, who according to tradition descended from Connacht, however migrated to Ulaid and after 600AD had joined the Uí Erca Céin;Crothraidi Buaingine, who are said to descend from Munster; and the Dál Coirb Fobair, a portion of whom where located in the south Antrim territory of Dál mBuinne, and are claimed to have descended from a Leinster prince called Cú Corb.
By the start of the historic period in Ireland in the 6th century, the over-kingdom of Ulaid was largely confined to east of the River Bann in north-eastern Ireland. The Cruthin however still held territory west of the Bann in County Londonderry, and their emergence may have concealed the dominance of earlier tribal groupings.
In 563, according to the Annals of Ulster, an apparent internal struggle amongst the Cruthin resulted in Báetán mac Cinn making a deal with the Northern Uí Néill, promising them the territories of Ard Eólairg (Magilligan peninsula) and the Lee, both west of the River Bann. As a result, the battle of Móin Daire Lothair (modern-day Moneymore) took place between them and an alliance of Cruthin kings, in which the Cruthin suffered a devastating defeat. Afterwards the Northern Uí Néill settled their Airgíalla allies in the Cruthin territory of Eilne, which lay between the River Bann and the River Bush. The defeated Cruthin alliance meanwhile consolidated itself within the Dál nAraidi dynasty.
The Annals of Ulster record that in 668, the battle of Bellum Fertsi (modern-day Belfast) took place between the Ulaid and Cruthin, both terms which then referred to the Dál Fiatach and Dál nAraide respectively. Meanwhile, the Dál nAraidi where still resisting the encroaching Northern Uí Néill. In 681, the Dál nAraidi led by Dúngal Eilni of the In Tuasicirt branch, along with their allies, the Cianachta Glenn Geimin of northern County Londonderry led by Cenn Fáelad, were killed at Dún Cethirinn by Máel Dúin mac Máele Fithrich of the Cenél Meic Ercae of Cenél nEógain.
Throughout the 7th century, the Cruthin had gradually lost their lands west of the River Bann, allowing Dál nAraidi to become the sole Cruthin dynastic grouping in County Antrim. After 776, the annals no longer refer to the Dál nAraidi as being of Cruthin stock, but to be of the Ulaid population-grouping instead, being called the fir-Ulaid, the "men of Ulster".
In the 8th century the kingdom of Dál Riata was overrun by the Dál nAraidi. Concurrently the Dál Fiatach extended their territory cutting off the Dál nAraidi from the Uí Echach Cobo. By the end of the 9th century the Dál nAraidi had taken control of Ulaid from the Dál Fiatach. This however only lasted until 972, when Eochaid mac Ardgail restored Dál Fiatach's dominance.
In 1005, Brian Boru, marched north to accept submissions from the Ulaid, which including marching upon the Dál nAraidi capital Ráith Mór where he received only the submissions of their king.
By the beginning of the 12th century the Dál nAraidi, ruled by the Ó Loingsigh (O'Lynch), had lost control of most of Antrim to the Uí Fhloinn (O'Lynn) and became restricted to the territory of Magh Line. The Uí Fhloinn were the ruling sept of the Airgíallan Uí Tuirtri as well as rulers of Fir Lí, and in a process of gradual infiltration by marital and military alliances as well as growing pressure from the encroaching Cenél nEógain, they moved their power east of the Bann. Once they had come to prominence in Antrim the Ua Flainn styled themselves as king of Dál nAraidi (in Tuaiscirt), Dál Riata, and Fir Lí, alongside their own Uí Tuirtri.
