* November 20 – Domnall Midi, High King of Ireland

Serious defeats in Ireland and Scotland in the time of Domnall Brecc ( d. 642 ) ended Dál Riata's " golden age ", and the kingdom became a client of Northumbria, then subject to the Picts.

* Domnall Midi ( before 715-763 ), King of Mide and High King of Ireland

Two kings of Ireland were Domnall Ua Lochlainn and Muirchertach Mac Lochlainn.

More contemporary sources suggest that the Kingship of Tara all but disappeared in the years following Diarmait's death, and that it was not until the time of Domnall mac Áedo, or perhaps of Fiachnae mac Báetáin, that there was a High King of Ireland again.

But he was also determined to defend his kingdom against predators such as Domnall Mac Lochlainn ( d. 1121 ), king of the north of Ireland.

Domhnall Ua Lochlainn ( old spelling: Domnall Ua Lochlainn ) ( 1048 – 10 February 1121 ), also known as Domhnall Mac Lochlainn ( old spelling: Domnall Mac Lochlainn ), claimed to be High King of Ireland.

The meaning, and even the definition, of the High Kingship of Ireland to which Domnall laid claim was far from clear in the period after the death of the last traditional Uí Néill king of Tara, Máel Sechnaill mac Domnaill of Clann Cholmáin, in 1022.

Domnall's legal men, for example, claimed that a High King " with opposition " was the king of a province who could lead his army throughout Ireland without defeat, and this Domnall could do.

Domnall's glowing obituary in the Annals of Ulster reads as follows: Domnall son of Ardgar son of Lochlann, over-king of Ireland, pre-eminent among the Irish in form and lineage, in sense and valour, in happiness and prosperity, in giving valuables and food, died in Daire Coluim Cille in the thirty-eighth year of his reign, the seventy-third year of his age, on Wednesday night, the fourth of the Ides 10 February 1121 and the eighteenth of the moon, the feast of Mo-Chuaróc the wise.

In the same year, his ally Olaf of York lost his throne and left for Dublin in Ireland.

* October 12 – Due to the advance of a royal force on his fortress of Ludlow, The Duke of York flees to Ireland, while his ally Warwick goes to Calais.

A former Fianna Fáil cabinet minister and a political ally of Lynch, Patrick Hillery, was eventually nominated ( without election ) as Ó Dálaigh's successor and sixth President of Ireland.

From the perspective of Great Britain, the union was required because of the uncertainty that followed the Irish Rebellion of 1798 and the French Revolution of 1789, which inspired the rebels ; if Ireland adopted Catholic Emancipation, willingly or not, a Roman Catholic parliament could break away from Britain and ally with the French, while the same measure within a united kingdom would exclude that possibility.

He remained " the enemy within ", recruiting malcontent MPs to harass the party and survived politically by dint of his assiduous constituency work, as well as through the influence of his clerical ally Dr. Michael Cardinal Logue, Primate of All Ireland and Archbishop of Armagh.

He first appears in 622, when the Annals of Tigernach report his presence at the battle of Cend Delgthen ( probably in the east midlands of Ireland ) as an ally of Conall Guthbinn of Clann Cholmáin.

Gruffudd and his ally Cadwgan ap Bleddyn retreated to Anglesey, but then were forced to flee to Ireland in a skiff when a fleet he had hired from the Danish settlement in Ireland accepted a better offer from the Normans and changed sides.

It quickly made a treaty with its old ally, the United Kingdom of Great Britain and Ireland on 26 February 1884 to block off the Congo Society's access to the Atlantic.

It portrays the marriage of the main Norman conqueror of Ireland " Strongbow " to the daughter of his Gaelic ally.

The Annals of the Kingdom of Ireland, recount how in 1601, Prince Hugh Roe O ' Donnell, on his way to the Battle of Kinsale, sent some of his kinsmen troops there to reconquer Ardfert, Lixnaw, and Ballykeally for his ally FitzMaurice.

The day after Beachy Head, 11 July 1690 ( N. S ), William decisively defeated Louis ' ally, King James, at the land Battle of the Boyne in Ireland.

The Confederates did rule much of Ireland up to 1649, but were riven by dissent and civil war in later years over whether to ally themselves with the English and Scottish Royalists in the Wars of the Three Kingdoms.

Flann was a former ally of Dublin, and still Áed's most important ally in the central part of Ireland.

It may be that Óengus was involved in wars in Ireland, perhaps fighting with Áed Allán, or against him as an ally of Cathal mac Finguine.

It is a matter of conjecture whether this appellation denoted merely an ally of strangers from other parts or, as has been suggested, more particularly a collaborator with the Norsemen, who were in those days raiding the coast of north west Ireland.

According to legend, Taisie, renowned for her great beauty, was betrothed to Congal, heir to the Kingdom of Ireland.

Congal Cennemigher Mac Fergus Fanad was high king of Ireland from 700 AD until his death in 710 AD.

Congal Cláiringnech (" the cripple "), son of Rudraige, was, according to medieval Irish legend and historical tradition, a king of Ulster and High King of Ireland.

Congal fitted out a fleet and left Ireland for Lochlann ( Norway ) to seek new allies.

Congal decided, rather than ravage his own country, to march on Tara and fight Lugaid Luaigne for the High Kingship of Ireland.

Congal ruled Ireland for fifteen or sixteen years, at the end of which he was killed by Lugaid Luaigne's grandson Dui Dallta Dedad.

By 916 fleets under Sihtric Cáech and Ragnall, said to be grandsons of Ímar ( that is, they belonged to the same Uí Ímair kindred as the Ímar who was killed in 904 ), were very active in Ireland.

His three foster-brothers, the three sons of Dond Désa, whom Conaire had exiled to Alba ( Britain ) for their crimes, had made alliance with the king of the Britons, Ingcél Cáech, and they were marauding across Ireland with a large band of followers.

In the west were the Gaelic ( Goidelic )- speaking people of Dál Riata with their royal fortress at Dunadd in Argyll, with close links with the island of Ireland, from which they brought with them the name Scots.

The Scottish Gaelic language arrived via Ireland due to the growing influence of the kingdom of Dál Riata from the 6th century onwards and became the dominant language of the southern Hebrides at that time.

As has been said, the origins of the link between Dál Riata in Scotland and Ireland are obscure.

This alliance was likely precipitated by the conquests of the Dál Fiatach king Báetán mac Cairill, one of the very few High Kings of Ireland not of the Connachta or the Uí Néill, who had sought to subjugate all of Dál Riata, and the Isle of Man as well.

The history of Dál Riata in Ireland after Mag Rath is not entirely clear.

The obvious conclusion is that whoever ruled the petty kingdoms of Dál Riata after its defeat and conquest in the 730s, only Áed Find and his brother Fergus drew the least attention of the chroniclers in Iona and Ireland.

If the Vikings had a great impact on Pictland and in Ireland, in Dál Riata, as in Northumbria, they appear to have entirely replaced the existing kingdom with a new entity.

Alex Woolf has suggested that there occurred a formal division of Dál Riata between the Norse-Gaelic Uí Ímair and the natives, like those divisions that took place elsewhere in Ireland and Britain, with the Norse controlling most of the islands, and the Gaels controlling the Scottish coast and the more southerly islands.

* Legends hold that this stone was the coronation stone of the early Dál Riata Gaels, which they brought with them from Ireland when settling Scotland.

All of Alt Clut's neighbours, Northumbria, Pictland and Dál Riata, are known to have sent armies to Ireland on occasions.

He won three more battles against the Fomorians, at Badbgna in Connacht, Cnamros in Leinster ( in which Artur, Nemed's first son born in Ireland, died ), and Murbolg in Dál Riata ( where his son Starn was killed by the Fomorian Conand ).

The Irish had always had contacts with the rest of the British Isles, and during the early 6th century they immigrated from the island of Ireland to form the kingdom of Dál Riata, although exactly how much conquest took place is a matter of dispute with historians.

In the early 620s, there is firm evidence of a war being waged between Edwin and Fiachnae mac Báetáin of the Dál nAraidi, king of the Ulaid in Ireland.

Previously thought to have been of Dál Riatan origin and descended from Fergus mac Echdach, their family is now assumed to have been that of the first king Óengus mac Fergusa, perhaps originating in Circinn ( presumed to correspond with the modern Mearns ), a Pictish family with ties to the Eóganachta of Munster in Ireland.

The annals vary as to whether the despatch of a fleet from Dál Riata to Ireland to aid Flaithbertach mac Loingsig in his war with Áed Allán should be placed in the reign of Eochaid, or that of his successor.

Ainbcellach mac Ferchair was king of the Cenél Loairn of Dál Riata, and perhaps of all Dál Riata, from 697 until 698, when he was deposed and exiled to Ireland.

His ancestors were part of the Dál gCais and were Lords of Corcu Baiscind in the Kingdom of Thomond ( later to become County Clare ) in Ireland.

The kingdom of Dál Riata was situated in modern Argyll and Bute, Scotland, and parts of County Antrim, Ireland.
