63-475: The Thomond MacMahons were part of the great tribal grouping, the Dál gCais, and claimed descent from Mahon O'Brien, son of Muirchertach Ua Briain , High King of Ireland . Corcu Baiscin was held by the descendants of Carbry Bascain until the 11th century, when the descendants of Mahon O’Brien conquered them. According to Frost, Mahone 'a quo MacMahon' died in 1129, leaving two sons Murtagh and Dermot, with Murtagh being

126-652: A geopolitically untenable position of his kingdom wedged between an expanding Tudor Kingdom of Ireland and Tír Eoghain under the O'Neill . Rossa Buidhe agreed to surrender and regrant his territories to the English Crown in Ireland and they became County Monaghan in the Kingdom of Ireland. The county was subdivided into five baronies with Farney , Cremorne, Dartrey , and Monaghan controlled by MacMahons and Truagh by McKennas . The MacMahons lost control of Monaghan after

189-484: A mere two years later when Plantagenet tried to grant Thomond to Philip de Braose this situation was overturned. The Dál gCais defeated a Norman army at the Battle of Thurles in 1174, where over 1,700 Normans were killed. The following year when Raymond le Gros captured Limerick through a naval invasion, Domhnall re-took it and burned it rather than have it in foreign hands. The twenty years after that were more secure for

252-582: A note made following the death of Mary Rua O'Brien in 1686 which refers to "her nephew Sir Terlagh McMahon". The title appears to have died out with him. After the defeats of the native Irish in the 17th century, many of the Clare MacMahons emigrated to serve in the Irish Brigade of the French Army . Patrice de MacMahon (1808–1893), was created Duke of Magenta , appointed Marshal of France , and later

315-526: A price of protection. His military prowess was such that the Earl of Desmond was forced to give back to Thomond what would later become County Limerick. Mac Fhirbhisigh hints that the men of Leinster planned to raise Tadhg to the High Kingship of Ireland before his death and claims he was the greatest Ó Briain since Brian Bóruma himself. Thomond was wealthy in the 15th century; Domhnall Mac Gormáin (died 1484)

378-420: A sept, or sub-clan, of Clann Nadsluaigh . They trace descent from The Three Collas to their patronymic namesake, Niall Mac Mathghamhna, who descended from Mathgamna, Lord of the ancient kingdom of Fernmaige, located in the modern Baroney of Farney . They ruled the kingdom of Oriel (Anglicisation of Airgíalla ) from 1243 to 1590 C.E. The Airgíalla Kingship was ended when Rossa Buidhe MacMahon, found himself in

441-470: A son of Tadhg Cael Uisce, for the kingship instead and revolted. Seeing an opportunity, Edward II offered Thomond to Thomas de Clare if he could take advantage of the Ó Briain feud. The events which followed have passed down to history as the Cathreim Thoirdhealbhaigh . After Brian briefly regained Clonroad with de Clare 's help, Toirdelbach arrived with support from Galway in the form of

504-470: A time of peace and plenty. The years 1426–1459 were marked by a succession of three sons of Brian Sreamhach reigning; Tadhg an Glemore Ó Briain , Mathghamhain Dall Ó Briain and Toirdelbhach Bóg Ó Briain . During this time, Mathghamhain Dall was deposed by his brother Toirdelbhach with the familiar military assistance of the de Burghs (whom he had formed a marriage alliance with). Greater things were to come from

Unlike Scottish clans which are defined by surnames recognized by Scottish law of the Court of the Lord Lyon , there is no definitive authority on which surnames are regarded as Irish clans. Clans of Ireland is a modern organization that was started in 1989 and has eligibility criteria for surnames to be included on their register of Irish clans. This includes that

630-957: The Cistercians at Holy Cross Abbey , Corcomroe Abbey , Kilcooly Abbey and Monasteranenagh Abbey , the Franciscans at Ennis Friary , Galbally Friary and Quin Abbey (the latter of which became a formidable college) and the Dominicans at Limerick Blackfriars. There were also many monasteries which predated Thomond such as Inis Cealtra Monastery, Scattery Island Monastery and Dysert O'Dea Monastery . Both St. Flannan's Cathedral in Killaloe and St. Mary's Cathedral in Limerick can be traced to Domhnall Mór Ó Briain. See Annals of Inisfallen (AI). List of Irish clans#Clann Nadsluaigh The following

693-533: The Eóganachta . The person most famously associated with this is Brian Boru , High King of Ireland , best known for his feats at the Battle of Clontarf . Four generations down the line and after providing three more High Kings, the Dál gCais were unable to hold onto all of Munster and so Thomond came into being as a separate entity. Between the mid-12th and late 13th century, when much of Ireland came under direct English control and/or settlement, Thomond too came into

756-852: The Irish Rebellion of 1641 . Led by Colla Mac O'brian MacMahon, the MacMahons rose in revolt with O'Neill and other Ulster clans in an attempt to seize Dublin Castle and overthrow the English Tudor kingdom. While the plot to capture Dublin Castle failed, the McMahons captured Castleblaney and Carrickmacross in Monaghan. However, the English defeated the Irish uprising and Monaghan land was passed to Protestant settlers. It

819-627: The Mac Carthaigh Kingdom of Desmond ( Deas Mhumhain "South Munster"). From the 12th to the 14th centuries, the Norman invasion and their multiple attempts to take Thomond from the Gaels was the main challenge to the realm. The picture was complicated by rival branches of the Ó Briain having varied political alliances with different Norman families; this created a fractured political sphere in Thomond. At

882-715: The President of France . The MacMahon family are still prominent in France; the family home is the Château de Sully outside Dijon . The motto of the Thomond sept of McMahons is "Sic Nos Sic Sacra Tuemur" , which means "Thus We Defend Our Sacred Rights” being Protectors of Church properties owned by the Kings of Thomond being the O'Brien Clan. The McMahon Clan is directly descended from legendary General and High King of Ireland Brian Boromie "Conquorer of

945-581: The Synod of Kells in 1152, three more sees in Thomond were created in the form of the Diocese of Kilfenora , the Diocese of Roscrea and the Diocese of Scattery Island . Roscrea was re-merged with Killaloe in 1168 and Scattery Island followed in 1189. The latter was re-created briefly during the 14th century before once again being merged back with Killaloe. Some of the Bishops of Killaloe attended Ecumenical Councils of

1008-534: The Anglo-Irish sphere. The de Clare family established a colony at Bunratty , while the Butler and FitzGerald families also made inroads. However, from the time of the Battle of Dysert O'Dea , Thomond was restored as a kingdom, with its rulers reinstating Limerick within their overrule. Not until the 1540s did the ruling O'Brien dynasty come under English rule. County Clare was sometimes known as County Thomond in

1071-627: The Anglo-Norman baron Arnulf de Montgomery , who were both united to the clan through marriage in 1102. Their claim to the High Kingship was countered by the O'Neill (Uí Néill) clan in Ulster under the leadership of Domnall MacLochlainn of Ailech. Though Muirchertach campaigned hard in the north, he was unable to obtain the submission of Ailech. When he fell ill in 1114 he was deposed by his brother Diarmait . Muirchertach did briefly regain power, but after his death in 1119 his brother's sons took control of

1134-655: The Anglo-Norman-controlled Lordship of Ireland until the 16th century. The exact origin of Thomond, originally as an internal part of Munster, is debated. It is generally held that the Déisi Muman pushed north-west starting from the 5th to the early 8th century, taking the area from the Uí Fiachrach Aidhne of the Connachta . Eventually, the Dál gCais rose to power in all of Munster, to the detriment of

1197-549: The Baronies of Ikerrin, Upper and Lower Ormond, Owney and Arra, and somewhat more than the western half of the Barony of Clanwilliam in the County of Tipperary; the Baronies of Owenybeg, Coonagh and Clanwilliam, and the eastern halves of the Baronies of Small County and Coshlea in the County of Limerick." The entire Province of Munster was under the control of the O'Brien (Ua Briain) clan under

Thomond Thomond ( Classical Irish : Tuadhmhumhain ; Modern Irish : Tuamhain ), also known as the Kingdom of Limerick , was a kingdom of Gaelic Ireland , associated geographically with present-day County Clare and County Limerick , as well as parts of County Tipperary around Nenagh and its hinterland. The kingdom represented

1323-629: The Bruce , which made his patron de Clare an enemy. Muircheartach who now reigned supreme in Thomond, was nominally on the side of the Lordship of Ireland due to his connection to de Burgh. The cousins fought at the Second Battle of Athenry . Muircheartach's brother Diarmuid mac Toirdelbach Ó Briain managed to destroy Donnchadh and most of Clann Briain Ruadh's supporters at the Battle of Corcomroe in 1317. The end of

1386-798: The Catholic Church in Rome ; this includes Constantín Ó Briain who participated in the Third Lateran Council and Conchobhar Ó hÉanna who was at the Fourth Lateran Council . Religious orders were present in Thomond and had establishments founded by them under the patronage of Kings of Thomond. This includes; the Canons Regular of the Augustinians at Canon Island Abbey , Clare Abbey , Inchicronan Priory , Killone Abbey and Limerick Priory ,

1449-587: The Danes at Clontarf". As are the O'Briens, who the McMahons have fought and married for 1,000 years. In the old Irish orthography, the Oriel MacMahon motto is "So Dorn Dona Dhubhfuillibh" and "So Dorn Dona Dhubhfuiltish" in reformed. The motto was originally a battle cry and roughly translates to "Here's a fist to the dark-blooded" , "This hand is raised against tyrants" , "Beware of retaliatory blows" or "Guard against counterblows" . The MacMahons of Oriel are

1512-590: The Earl of Kildare, Silken Thomas . In 1534, a rumour had spread that his father, the Lord Deputy of Ireland , had been executed in England on the orders of king Henry VIII and that the same fate was planned for him and his uncles. Under this impression, Thomas threw off his offices in the Kingdom of Ireland and rose up in rebellion. He took refuge with the Ó Cearbhaill of Éile and then with Conchobhar mac Toirdhealbaig Ó Briain at Clonroad, Ennis . In hot pursuit, at

1575-590: The East (known as Clonderalaw). The two ruling branches of the clan became firmly established in Corcabaskin , West Clare , where their once strongholds, Carrigaholt Castle and Clonderlaw Castle , are prominent landmarks and a source of local interest today. In August 1585, the Irish leaders of Thomond were forced to sign an Indenture with Sir John Perrott, the English Lord Deputy of Ireland. Frost says that "some of

1638-565: The English title. The last chief of the West Corcabaskin MacMahons, Sir Teige Caech MacMahon, was killed at or shortly after the battle of Kinsale in 1602, and his title became extinct. Sir Turlough Roe MacMahon, Baronet of East Corcabaskin, received the honour of becoming High Sheriff of County Clare in 1609. He died in 1629. According to an Inquisition held at Ennis in 1630 (reported in Frost's "History ... of Clare"), Turlough's title

1701-558: The Gaels of Thomond. After the death of Domhnall Mór a period of destructive feuding among his offspring caused a great territorial decline in Thomond. The brothers Muircheartach Finn Ó Briain and Conchobhar Ruadh Ó Briain fought with each other, seeing Muircheartach's reign interrupted between 1198 and 1203. Muirchertach himself was blinded by the Normans in 1208 and was soon forced into abdication due to no longer being righdamhna . Donnchadh Cairprech Ó Briain had to deal with dissent from

1764-609: The Mac Con Mara and Ó Coinn against his rule, so brought in the Laigin 's Mac Gormáin as his standard bearers. Donnchadh also enlisted the support of the de Burgh and other Normans in this fight, which came at a costly price; Limerick and lands surrounding it in what would later become County Limerick and County Tipperary . Under pressure from the Butlers, Thomond was now not too different from what would become County Clare , protected by

1827-663: The Norman settler-colonialist project in Thomond was at an end until the submission of the Ó Briain in the 16th century. The Norman Lordship was weakened by the Bruce Wars of 1315–1318, the Black Death of 1349–1350 (which disproportionally hit Norman controlled towns) and besides that English forces were more invested with the Hundred Years' War in France and their own internal conflict the Wars of

1890-483: The River Shannon. Donnchadh moved his capital to Clonroad . The Normans' advance continued during the reign of Conchobhar na Suidaine Ó Briain , as Henry III "granted" lands to Robert de Muscregos and John Fitzgeoffrey . Of the two de Muscregos was most active, constructing Clare Castle and Bunratty Castle with a colony. The precedent for Thomond was very dangerous as, should much more land have been taken,

1953-551: The Roses to focus too much on Ireland. All of these factors allowed for a 15th-century Gaelic resurgence, not only in Thomond but across a significant part of Ireland outside of the Pale . Brian Bán was the last of Clann Briain Ruadh to hold the kingship and from 1350 onwards, Clann Tadhg held sway. Mathghamhain Maonmhaighe Ó Briain came to power before the death of his uncle Diarmuid and he

2016-405: The added benefit of winning back Limerick for Thomond and Sioda Cam Mac Con Mara was placed in the city as a warden in 1369. The friendship with the de Burghs of Galway was maintained by Brian and when Richard II was at Waterford in 1399, he paid nominal homage and was well received. Thomond was now in such a position that Conchobhar mac Mathghamhna Ó Briain 's twenty six-year reign was marked as

2079-674: The ancestor of the main line of McMahons in Clare. The McMahons seized the Corcabaskin territory in the south of what is now County Clare in the 12th century about the same time as they adopted the fixed surname. Quoting the "Annals of the Four Masters", Frost says that Donogh MacMahon, Lord of Corcabaskin, died in 1488 and two MacMahons, Brian and Teige Roe, were established in his place – Brian in West Corcabaskin (known as Moyarta) and Teige Roe in

2142-526: The ascent of Toirdelbhach's son Tadhg an Chomhaid Ó Briain . From Inchiquin , Tadhg took advantage of the Wars of the Roses, forming an alliance with the Ó Néill in 1464. He managed to ride south through Desmond (the rest of the old Munster) and enforce the cíos dubh on the Anglo-Normans. This was a kind of Gaelic pizzo which Tadgh's great-grandfather Mathghamhain Maonmhaighe had first been able to enforce as

2205-516: The castle was attacked by Grey, it surrendered due to Donnchadh. With the loss of east Thomond and the destruction of O'Brien's Bridge , Thomond was in a lot of trouble. Conchobhar, along with loyal supporters such as the Mac Con Mara , continued to fight on and managed to conclude a truce with Grey in 1537. Conchobhar was succeeded on his death by his brother Murchadh Carrach Ó Briain , a man who initially attempted to assist Conn Bacach Ó Néill in

2268-492: The choice. Tadhg was proud and stubborn, declaring his father should be High King; the Dál gCais thus did not take part in the Battle of Druim Dearg , which the Gaels lost, damaging the reputation of Thomond as a consequence. Brian Ruadh Ó Briain kept the pressure up by burning Clare Castle and forcing the de Muscregos' to flee to Wales , but he had troubles from his own countrymen. The Mac Con Mara, Ó Deághaidh and Mac Gormáin clans supported his nephew Toirdelbach Ó Briain ,

2331-411: The clan. MacLochlainn's plans to restore the High Kingship to the north was thwarted by his ally Tairrdelbach Ua Conchobair of Connacht who formed an alliance with the O'Brien's. In 1118 Conchobair partitioned Munster between the sons of Diarmait and Tagh Mac Carthaig. The northern section of the province became the O'Brien Kingdom of Thomond ( Tuadh Mhumhain "North Munster") and the southern became

2394-565: The core homeland of the Dál gCais people, although there were other Gaels in the area such as the Éile and Eóganachta , and even the Norse of Limerick . It existed from the collapse of the Kingdom of Munster in the 12th century as competition between the Ó Briain and the Mac Cárthaigh led to the schism between Thomond ("North Munster") and Desmond ("South Munster"). It continued to exist outside of

2457-471: The de Burghs and once again took control in 1277. Brian was executed by his "ally" at Bunratty, but de Clare was soon reconciled with his son Donnchadh mac Brian Ó Briain and supported him against Toirdelbach. The feud continued until Donnchadh drowned at a party on Islandmagrath , on the River Fergus . With Toirdelbach now undisputed king, the Mac Con Mara were able to hound de Clare. The conflict between

2520-445: The de Clares and Norman territorial claims in Thomond came the following year at the Battle of Dysert O'Dea , where Conchobhar Ó Deághaidh held out against a larger English force until the O'Brien and allies could reach the battle and decisively secure victory. The last successful attempt by a Norman to play divide and conquer within the Thomond kingship was the case of Maurice FitzGerald , Earl of Desmond. A very powerful man, he

The Parliament of the Kingdom of Ireland was called to Limerick in 1542 by Lord Deputy Anthony St. Leger regarding the terms of submission of Murchadh Carrach Ó Briain and Sioda Mac Con Mara.

2772-408: The head of an army, was Lord Leonard Grey , who destroyed the Killaloe Bridge , which had the result of isolating Thomond from the rest of Ireland and also attacked the Dál gCais east of the River Shannon. Although the Silken Thomas issue was resolved by late 1535, Thomond had marked itself out by providing refuge to enemies of the Crown of England in Ireland. The English forces had in turn enlisted

2835-457: The holder of other lands in that County. There is evidence that Sir Teague had a son called Turlough (or Terlagh). Honour, Lady Dowager of Kerry and Lixnaw, was granted the "guardianship and tuition of Torlogh MacMahon, son and heir to Teague MacMahon" on 27 June 1673 (recorded in MS Carte 38, fol(s) 742v (Carte Calendar Vol 52, 1673–1674, Bodleian Library, Uni of Oxford).

2898-423: The leadership of Toirrdelbach Ua Briain and his son Muirchertach from 1072 to 1114. Their capital was located in Limerick. In a bid to secure the High Kingship of Ireland for the clan, Muirchertach encouraged ecclesiastical reform in 1111 with the creation of territorial dioceses over the entire island. They had support for their bid from several foreign connections including the Norwegian king Magnus Bareleg and

In 1841, an estimation of the extent of the kingdom was undertaken by John O'Donovan and Eugene Curry "The principality of Thomond, generally called the Country of the Dal-Cais, comprised the entire of the present Co. of Clare, the Parishes of Iniscaltra and Clonrush in the County of Galway, the entire of Ely O'Carroll,

3024-432: The realm would have no longer existed. Conchobhar and his fiery son Tadhg Cael Uisce Ó Briain took up arms and slaughtered many of the Norman settler-colonists in 1257. The following year, the Gaelic chiefs from all over Ireland had resolved to form an anti-Norman pact and met at Cael Uisce , near Lough Erne to discuss terms. They planned to resurrect the High Kingship of Ireland , with most supporting Brian Ó Néill as

3087-439: The services of Conchobhar's own son Donnchadh Ó Briain who had cemented an alliance with the Butler family by marrying the daughter of the Earl of Ormond . According to Butler, Donnchadh pledged to help them conquer Thomond, aid English colonisation, adopt English laws and help them take over Carrigogunnell Castle. This castle was a symbol of Gaelic defiance, as it had remained out of Anglo-Norman hands for over 200 years. When

They were allowed to retain their castles and lands free of crown rent. The two MacMahons would have received the English titles of Baronet, replacing their traditional Irish titles, about this time. The two sons who succeeded them as heads of their families certainly each carried

The discord dragged on and Thomond was under the martial law of William Drury as late as 1577. The issues pertaining to tax and land were finalised at the Composition of Thomond in 1585. The religion which predominated at an official level in Thomond

3276-413: The time of the Norman invasion of Ireland in 1169, Domhnall Mór Ó Briain was king of Thomond. Domhnall was a man of realpolitik ; his main concern was upholding his position in Thomond and was not against collaborating with Strongbow and others against rival Gaelic kingdoms such as Ossory , Desmond and Connacht . Domhnall even acknowledged Henry II as Lord of Ireland at Cashel in 1171, but

3339-651: The two lines continued into the next generation between Donnchadh mac Toirdelbach Ó Briain (backed by William Liath de Burgh ) and Diarmuid Cléirech Ó Briain (backed by Richard de Clare ). There was military success at Bunratty in 1311 for Diarmuid and his cousin Donnchadh was killed at Corcomroe . Following this, Clann Tadhg's leader was Muircheartach mac Toirdelbach Ó Briain and after Diarmuid's "sudden" death, Clann Briain Ruadh's leader became Donnchadh mac Domhnall Ó Briain . The Bruce Wars in Ireland added an unpredictable element and saw some surprising ad hoc alliances come into play. Donnchadh elected to support Edward

Toirdelbhach's life came to an end trying to defend the Ó Cearbhaill of Éile from the Earl of Ormond at Camus, near Cashel; he died "by the shot of a ball." The downfall of Thomond occurred in the 16th century. The series of events leading up to it, were set into process by the rebellion of FitzGerald family member,

3591-404: Was constantly rumoured during his life to have wanted to make himself King of Ireland. He successfully sponsored Brian Bán Ó Briain in overthrowing Diarmuid from Clan Tadhg during 1343–1350, but equally decisive was the sides taken by Mac Con Mara, leading to Diarmuid's restoration. With the exception of a failed Norman attempt to reconstruct Bunratty Castle by Thomas de Rokeby from 1353 to 1355,

3654-414: Was convicted of treason and beheaded in London on 22 November 1644.

During the reign of Conchobhar na Srona Ó Briain , Thomond maintained alliances with the Mac William Uachtar of Clanricarde and the Butlers. In the latter case, they were opposing the Kildare FitzGeralds, earning the ire of Gerald FitzGerald , Earl of Kildare who had earned the favour of the new Tudor king Henry VII as Lord Deputy of Ireland. Despite Kildare's fearsome reputation, Conchobhar met him in battle at Ballyhickey, near Quin , in 1496 and

3780-407: Was inherited by his eldest son, Sir Teige MacMahon. Sir Teige (or Teague) represented the Earl of Thomond in negotiations with Sir William Penn in 1646, but in 1651 General Ireton seized Clonderlaw Castle from Sir Teige.

Dissent took place in the form of Donchadh's brother Domhnall Ó Briain (and his ally Tadhg Ó Briain ) who claimed to have been inaugurated Chief of the Ó Briain according to the Gaelic fashion in 1553. This was in opposition to his nephew the Earl, Conchobhar Groibleach Ó Briain . Tied into English political rivalries, Conchobhar had
