The O'Donnell dynasty (Irish: Ó Dónaill or Ó Domhnaill; derived from the Irish name Domhnall, which means "ruler of the world", Dónall in modern Irish) were an ancient and powerful Irish family, kings, princes and lords of Tyrconnell (Tír Chonaill in Irish, now County Donegal) in early times, and the chief allies and sometimes rivals of the O'Neills in Ulster.

Like the family of O'Neill, that of O'Donnell of Tyrconnell was of the Uí Néill, i.e. descended from Niall of the Nine Hostages, High King of Ireland at the beginning of the 5th century; the O'Neill, or Cenél nEógain, tracing their pedigree to Eógan mac Néill, and the O'Donnells, or Cenél Conaill, to Conall Gulban, both sons of Niall. Conall was baptised by St. Patrick.
Arms and motto
The Roman Emperor Constantine the Great converted to Christianity after a vision before the famous Battle of the Milvian Bridge, having seen a chi-rho in the sky, and thence the motto In Hoc Signo Vinces, telling him he would be victorious with the sign of the cross. The chi-rho was adopted on a banner, the labarum, upheld on a vexillum, which resembled a Christian cross, and in time the motto became associated with the Cross all over Europe. Legend has it that St. Patrick struck the shield of Conall, son of King Niall of the Nine Hostages, with his crosier, called Bachall Isa (the staff of Jesus) inscribing thereon a sign of the cross and told him the same, and baptized him. According to the Life and Acts of Saint Patrick (chapter 138), commissioned by Sir John de Courcy and written by Jocelyn of Furness (c. 1185 AD), St. Patrick took his staff, known as the staff of Jesus, or Bacall Iosa, and struck the shield of Prince Conall, rendering a sign of the Cross on it, “et mox cum baculo suo, qui baculus Jesu dicebatur Crucis signum ejus scuto impressit, asserens neminem de stirpe ejus in bello vincendum qui signum illud”, and thus indicating that he and his offspring would henceforth be victorious in battle if they followed that sign This legend is also described several centuries later in the Lebhar Inghine i Dhomhnaill. His land became Tír Chonaill, Tyrconnell, the land of Conall.
Conall's Constantinian shield, and this motto, have been the main O’Donnell arms in various forms, through the centuries. The motto also appears prominently placed as a motto on a ribbon unfurled with a passion cross to its left, beneath a window over the Scala Regia, adjacent to Bernini's equestrian statue of Emperor Constantine, in the Vatican. Emperors and other monarchs, having paid respects to the Pope, descended the Scala Regia, and would observe the light shining down through the window, with the motto, reminiscent of Constantine's vision, and be reminded to follow the Cross. They would thence turn right into the atrium of St. Peter's Basilica, ostensibly so inspired. In an earlier version (before Bernini's renovations in the mid-17th century), something similar may have resonated with and been observed by Prince Rory O'Donnell, 1st Earl of Tyrconnell following his visit to Pope Paul V (at the Palazzo Quirinale) in Rome, just prior to his death in 1608. It would certainly have resonated with and been observed by Cardinal Patrick O'Donnell.
Tyrconnell, the territory named after the Cenel Conaill, is the vast territory where the O'Donnells held sway, comprised the greater part of the modern county of Donegal except the peninsula of Inishowen. But it also included areas outside Donegal, such as the baronies of Carbury in County Sligo, Rosclogher in County Leitrim, and Magheraboy and Firlurg in County Fermanagh, and part of southern County Londonderry, hence it straddled the modern Republic of Ireland and also part of Northern Ireland in the UK. The jewel in the O'Donnell crown was Donegal Castle, one of seven O'Donnell castles, and now a national monument partially restored by the Office of Public Works. Tyrconnell also therefore bordered on territory ruled by the O'Neills of Tyrone, who were periodically attempting to assert their claim of supremacy over it, and hence the history of the O'Donnells is for the most part a record of clan warfare with their powerful neighbours, and of their own efforts to make good their claims to the overlordship of northern Connacht, and a wider swathe of Ulster. Nonetheless Tyrconnell existed for a period as an independent kingdom, recognised by King Henry III of England (see Close Roll, in the Tower of London, 28 Hen. 3m.7).
Gofraidh Ó Domhnaill, the first chieftain, was son of Domhnall Mór Ó Domhnaill. In 1257, Gofraidh was victorious when he went to battle at Creadran-Cille against Brian Ua Néill. Upon Gofraidh's death, subsequent to wounds incurred during battle against Ó Néill, he was succeeded in the chieftainship by his brother Domhnall Óg, who returned from Scotland in time to withstand successfully the demands of Ó Néill. 
Patronage of the O'Donnell dynasty
The O'Donnells were patrons of the arts, and of religious benefices. In particular, one, Manus, wrote the biography of ColmCille (St. Columba). They also were the patrons of the Franciscans in Donegal Abbey. They also exercised "jus patronus" to nominate bishops.
Charity of the O'Donnell dynasty
In the early 14th century A.D., the O'Donnell rulers aided Templar knights fleeing via Sligo and Tyrconnell to Scotland where a Templar priory existed at Ballymote , a Percival family estate for the last 300 years.
The O’Donnell rulers of Tyrconnell are also noted for having, even, earlier, in the late 12th century A.D. and for centuries thereafter, graciously given succor and dignities to their former foes the MacDonlevy (dynasty) rulers of Ulidia (kingdom), after that eastern Ireland kingdom fell to the English. While under the O’Donnell dynasty’s protection in the Kingdom of Tyrconnell or Irish Tir Chonaill, that is “land or territory of the O’Donnell”, the MacDonlevy (Gaelic language Mac or Ó Duinnshléibhe) were also known by the agnomen Ultaigh or in variant spelling Ultach (Mac an Ultaigh (Irish language surname), anglicized MacNulty) for their Nation of origin the Ulaidh. During their exile in Tyrconnell, The O’Donnell even named his deposed fellow Gael royals the MacDonlevy, who were also one of the ancient hereditary medical families of Ireland, to the high Gaelic status of “ollahm leighis” or his official physicians.
It was in fact two of these deposed MacDonlevy (> MacNulty) royals and Roman Catholic priests thereto exiled in Tyrconnell, Fathers Muiris Ulltach in full Muiris mac Donnchadh Ulltach Ó Duinnshléibhe and Muiris Ulltach in full Muiris mac Seaán Ulltach Ó Duinnshléibhe, who both along with the Archbishop of Tuam attended Hugh Roe O'Donnell (aka Red Hugh O’Donnell), The O'Donnell of 1601 Kinsale fame, in his exile at his death bed at Simancas Castle in Spain in 1602. And, it was in turn an Irish Count O’Donnell, who compassionately married the widow (d. 1708) of Don-Levi, a Jacobite (Jacobitism) and, thereby, on James II of England's and his French allied's failure to reclaim his British crowns, the last The MacDonlevy to sit in Ireland (departed 1691), after this prince died in exile with the Stuarts in France at the Archbishopric of Treves. This union of the MacDonlevy and the O'Donnell, though, bore no issue.
In absence of these indulgences of the O’Donnell dynasty kings having maintained the MacDunleavy/MacNulty physicians of Tirconnell as a dignified community, it is debatable whether they could have so influenced the course of western medicine, educating and training Niall Ó Glacáin (L. Nellanus Glacanus) in the medical arts, so he could later on the Continent apply empirical method to pioneer the field of forensic anatomy and pathology, first describe the petechial haemorrhages of the lung and swelling of the spleen incident of bubonic plague (Tractatus de Peste, 1629), and early elucidate the empirical method of differential diagnosis for the continental European medical community, and producing the medieval physician and medical scholar Cormac MacDonlevy translator from Latin to vernacular of Bernard de Gordon's Lilium Medicine, Gaulteris Agilon's De dosibus and Gui de Chuliac's Chirurgia.
Later in the early 13th century, the O’Donnell also gave succor to the Ó Cléirigh kings of Uí Fiachrach Aidhne. Onara Ultach was descended of the MacDonlevy (dynasty) royals of Ulidia (kingdom), who as above noted after the fall of that Ulster kingdom to the Anglo-Norman forces of Henry Plantagenet served as ollam lieghis or the official physicians to the O'Donnell kings of Tyrconnell. Onara married Donnchadh Ó Cléirigh, a son of the Chief of the name of the Ó Cléirigh family then also of Tyconnell. The Ó Cléirigh were too a learned Irish royal family that had lost their sub-kingdom in Uí Fiachrach Aidhne in what is today County Galway to the Anglo-Norman forces of Henry Plantagenet. The Ó Cléirigh then went into service of the O’Donnell as poet historians, scribes and secretaries or official bards, called in Irish language "ollam righ". Onara bore for Donnchadh a son Mícheál Ó Cléirigh (c. 1590 – 1643), anglicized Michael O’Cleary, who matured to become the principal author of the Annals of the Four Masters. But for the manifold grace of the O’Donnell, this union would never have occurred, and Michael O’Cleary never lived to memorialize this history of Gaelic Ireland.
The Royal Household was known in Gaelic as "Lucht Tighe" and comprised several offices that were performed on a hereditary basis by the heads and members of particular other families, for over four centuries.

Later struggles and diaspora
The O'Donnells defeated the O'Neills in the 1522 Battle of Knockavoe. In 1541 Manus O'Donnell took part in the "Surrender and regrant" process. In 1567 the O'Donnells won the Battle of Farsetmore against the O'Neills, reconfirming their autonomy in Ulster.
During the Nine Years' War of 1594-1603, the O'Donnells of Tyrconnel played a leading part, led by the famous Prince Red Hugh O'Donnell. Under his leadership, and that of his ally Hugh O'Neill, they advanced to Kinsale and laid siege to the English forces in anticipation of a Spanish invasion. En route, they implanted some O'Donnell kinsmen in Ardfert and Lixnaw to protect the territories of their ally, FitzMaurice, Lord of Kerry. The Battle of Kinsale was lost in 1601, heralding the end of the Gaelic order and Brehon Laws in Ireland, and the completion of the Elizabethan conquest. Following the Treaty of Mellifont of 1603 the new King James I pardoned Rory O'Donnell and created him Earl of Tyrconnell in the Irish peerage.
Rory then unfortunately joined in the Flight of the Earls in 1607, which led to the title becoming attainted in 1614, and Tyrconnell and Ulster being colonised in the Plantation of Ulster. He died in exile in Rome in 1608.
The head of the dynasty was traditionally also called "The O'Donnell", and inaugurated as Chieftain in an elaborate ceremony, under the Laws of Tanistry, part of the ancient Brehon Code of Law. Since the collapse of Gaelic Rule and the Brehon legal system, the succession of the "Chiefs of the Name" has followed the principle of male primogeniture.
On this basis, the current nominal head of the O'Donnell Clan (Clann Domhnaill), who bears the courtesy title of "The O'Donnell", i.e. the latest in the line of Chiefs of the Name of O'Donnell of Tyrconnell, customarily recognised as a Prince, is Fr. Hugh O'Donel, O.F.M., a Franciscan priest in Dublin who recently retired from missionary work in Zimbabwe. His widely recognised Tánaiste (or heir apparent) as The O'Donnell of Tyrconnell, Prince and Chief of the Name of O'Donnell, is S.E. Don Hugo O'Donnell, Duke of Tetuan, a Grandee of Spain. He is known as S.E. Don Hugo O'Donnell y Duque de Estrada - the latter appendant Duque de Estrada is not a title but a maternal family name. Don Hugo is an active member of the Clan Association of the O'Donnells of Tyrconnell, and a member of the nobiliary Sovereign Military Hospitaller Order of Saint John of Jerusalem, of Rhodes, and of Malta, i.e. a Knight of Malta.

Cardinal Patrick O'Donnell was probably the next most famous O'Donnell to emerge in Ireland after the exile of Rory O'Donnell, 1st Earl of Tyrconnell. Thomas O'Donnell (MP) for West Kerry (1900–1918) was a leading agrarian reformer, and the first Member of Parliament to address the House of Commons in Westminster in the Irish language (Gaelic), but was called to order by the Speaker, but not without having made his mark with John Redmond's support. There is currently an Irish Senator from County Donegal named Brian o Domhnaill (o Donnell).

- Susan Wilkinson, “Early Medical Education in Ireland”, Irish Migration Studies in Latin America, Vol. 6, No. 3 (November 2008) pp 157-158, discussing the high status that physicians were accorded in ancient Gaelic society and, specifically, the particularly high status of "ollahm leighis". Wilkinson also alludes that the high status accorded the king’s physician was due in no small part to the fact that many a battle wounded Gaelic chief owed his life to these skilled physicians and field surgeons, “Every Irish chieftain was accompanied into battle by his personal liaig, and not a few owed their lives – following near fatal spear or sword injuries – to the skills of their Druid physician.” and, also, at footnote 2 of cite “The word “liaig” means ‘leech’, an archaic term for a doctor or healer. The term is often used for a Druidic doctor in ancient texts.” Leeching (medical) for millennia was in Ireland as elsewhere a commonly employed ancient medical practice.
- Edward MacLysaght, The Surnames of Ireland, 5th Edition, Irish Academic Press, Dublin, 1980, p 238, 292, who cites to 2 entries in The Annals of the Four Masters, which is a historical chronicle that records, among other matter, the births and deaths of Gaelic nobility. The first entry cited is an entry recording the 1395 A.D. death of a Maurice, the son of one “Paul Utach”, who is, himself, recorded there to be “Chief Physician of Tyrconnell” and also as “Paul the Ulidian”. It is there in the Annals further stated by its authors of the father Paul Ultach that “This is the present usual Irish name of the Mac Donlevy, who were originally chiefs of Ulidia. The branch of the family who became physicians to O’Donnell are still extant (at time of compilation of the Annals in the 17th century just after the fall of this last Gaelic sovereignty of Tirchonaill, itself, in 1607), near Kilmacrenan, in the county of Donegal.” The second citation is to an entry recording the 1586 A.D. death of "Owen Utach", who is therein noted to be a particularly distinguished and skilled physician. The Annals compilers further elaborate of Owen Ultach at this entry that “His real name was Donlevy or, Mac Donlevy. He was physician to O’Donnell.”
