An English crown possession carved out by adventurers who came to restore an exiled Leinster king, reduced within two centuries to a fortified strip around Dublin, and elevated by its own Parliament's unanimous vote in 1541 from a lordship into a kingdom.

Diarmait Mac Murchada abducts DerbforgaillRevoltContested
Diarmait, king of Leinster, carried off Derbforgaill, wife of Tiernan O'Rourke of Breifne, with her own apparent consent - an injury O'Rourke never forgave, and one later chroniclers treated as the seed of the feud that would cost Diarmait his own kingdom fourteen years later.

A coalition led by O'Rourke and the high king Rory O'Connor expelled Diarmait from his own kingdom. He crossed to England and then to France to seek Henry II's help, receiving only a royal letter permitting any of the king's subjects to aid him, since Henry himself had pressing business elsewhere.

Strongbow arrived with a force of knights, stormed Waterford, and married Diarmait's daughter Aoife there on the spot - securing, by the agreement struck at Bristol, his own inheritance of the whole kingdom of Leinster on Diarmait's death.

Alarmed that Strongbow might carve out an independent kingdom of his own, Henry II landed with a large force that October. A synod at Cashel brought the Irish church into line with Roman practice, and Irish kings and Anglo-Norman lords alike gave way before him rather than risk a fight - the conquest absorbed into a royal lordship instead of standing as an independent baronial state.

Richard de Burgh intervenes in ConnaughtSuccession crisis
A contested succession to the kingship of Connaught after Cathal Crobderg's death drew in Anglo-Norman lords, Richard de Burgh chief among them, as indispensable allies of the Irish claimants who needed their swords. Over the following decades that dependence hardened into outright lordship, and by the century's end the de Burghs held both Connaught and Ulster - two of the largest Anglo-Norman territorial blocks in Ireland, and the widest extent the lordship's own territory would ever reach.

His 1537 execution, alongside five of his uncles, ended the House of Kildare's decades-long function as the crown's own hereditary governor of Ireland - and with it, the model of ruling the lordship through a semi-independent Anglo- Irish magnate family that had held since the 1460s.

A wife who loved another lord
formationDrafted from Furnivall), Early English Text Society (1896)
Diarmait Mac Murchada ruled Leinster as one of Ireland's more powerful
provincial kings, and had, by most accounts, made himself hated among
his own nobles as thoroughly as any of his rank. The event later
chroniclers fixed on as the seed of his eventual ruin was one born of
private passion rather than politics: Tigernán Ua Ruairc of Bréifne
held as his wife a woman named Derbforgaill, and she and Diarmait had
loved each other for some time before either found the chance to act
on it.
An abduction with the lady's own consent
The opportunity came when Ua Ruairc left his own territory on
business abroad. Derbforgaill sent word to Diarmait that she was
ready to do as he wished if he would only come for her, and he
gathered a following and carried her off into Leinster - by the
chronicle's own telling, willingly on her part, whatever show of
distress she made for appearances. Ua Ruairc, informed of the affair
on his return, was consumed less by the loss of his wife, the account
says, than by the shame of it, and set about gathering every ally he
could find against Diarmait.
A grudge with a long memory
Nothing about the affair itself immediately cost Diarmait his throne;
years passed before the consequences caught up with him. But the
enmity it created in Ua Ruairc proved durable in a way few political
quarrels of the period were, and when a wider coalition against
Diarmait finally formed in 1166, Ua Ruairc's own old grievance was
central to it - a private wrong from fourteen years earlier furnishing
the occasion, if not quite the sole cause, for driving one of
Ireland's provincial kings into an exile that would change the
country's history far beyond anything either man could have intended.
A letter instead of an army
formationDrafted from Furnivall), Early English Text Society (1896)
In 1166 the coalition Tigernán Ua Ruairc had spent years assembling -
joined by the high king Rory O'Connor himself - drove Diarmait Mac
Murchada out of Leinster entirely. He crossed first to England, then
on to France, where King Henry II was occupied with other business
of his own. Diarmait had nowhere else obvious to turn: he asked Henry
for help restoring him to his kingdom.
A grant of permission, not of soldiers
Henry received him courteously and sympathized with his case, but had
no intention of committing an army of his own to an Irish succession
dispute. What he gave instead was a letter, addressed to all his
subjects - English, Norman, Welsh and Scottish alike - declaring that
he had received Diarmait into his grace and permitting any who wished
to help restore him to do so freely, with the king's own blessing.
Diarmait, provided with money from Henry's own treasury besides,
crossed to Bristol to make what he could of the offer.

Recruiting an army from a royal permission slip
He spent time at Bristol reading the king's letter aloud to whoever
would listen, and promising land, rents, and rich gifts to any who
would come fight for him. For a long while no one of real substance
answered. Only when Richard de Clare, Earl of Strigoil - a man whose
own fortunes in England had faded, and who had every reason to want
what Diarmait was offering - finally came to him did the enterprise
gain the backing it needed. Their agreement was blunt: Strongbow would
help Diarmait with all the force he could muster the following summer,
and in return would receive Diarmait's own daughter in marriage, along
with the whole of Leinster to go with her.
A king follows his own barons

Strongbow's own campaign succeeded faster and more completely than
anyone, Henry II included, had quite expected. He landed at Waterford
in August 1170, stormed the town, and married Aoife, Diarmait's
daughter, among the ruins that same day - a wedding conducted, by
every account, with the ordinary business of a battle's aftermath
still visible around it. Dublin fell soon after. When Diarmait died
the following spring, Strongbow claimed the whole of Leinster as his
own inheritance through his wife, exactly as their agreement had
promised.

An earl grown too independent
A Norman baron ruling an Irish kingdom in his own right, answerable to
no one, was not the outcome Henry II had authorized when he wrote his
permissive letter at Diarmait's request. Alarmed at what his own
subject was building across the Irish Sea, Henry crossed to Waterford
in person that October, at the head of a force large enough to leave
no doubt about who held the greater power between them.
Submission, and a synod to match it
Strongbow submitted at once, surrendering Dublin and the coastal towns
to the crown and holding the rest of Leinster only as the king's own
tenant thereafter. Irish provincial kings, watching an army larger
than any yet seen in Ireland, largely followed his example rather than
risk finding out what resistance would cost. A synod convened at
Cashel that winter brought the Irish church's own practices - on
marriage, tithes and the sacraments - into closer conformity with Rome
and, by extension, with the reforming programme Henry's own bishops
were pursuing in England. What had begun as one exiled king's private
bid to reclaim his throne ended, within five years, as a lordship of
the English crown spanning most of the island's eastern half.

A seneschal builds an earldom
peakDrafted from Orpen, 4 vols (1911-1920)
The century after Henry II's submission at Waterford was the lordship's
own territorial peak, and no single family did more to reach it than
the de Burghs, whose conquest of Connaught turned a province still
ruled by its own Irish kings into the last great Anglo-Norman earldom
on the island.
A kingship inherited like a fief
When the Connaught king Cathal Crobderg died in 1224, his son Aedh
succeeded him in a manner the Irish annals themselves treated as
unusual - not through the acclamation of the Uí Briúin's own
chieftains by ancient custom, but as something closer to a hereditary
fief passing from father to son, backed by the English justiciar's own
support. The succession was contested almost immediately. Rival
claimants among Cathal's own kinsmen, backed by the king of Tyrone,
rose against Aedh within the year, and the fighting that followed drew
in Anglo-Norman forces from both the north and south of the province -
among them Richard de Burgh, recently appointed seneschal of Munster,
whose own family had held a hereditary claim on Connaught since the
previous generation. Aedh could not do without Norman help, and the
Norman lords who supplied it did not do so for nothing.
A conquest paid for in installments
What followed was not a single campaign but decades of intervention,
each round of internal Connaught politics giving Anglo-Norman lords a
fresh pretext to intervene, extract concessions, and entrench their own
following further into the province's own territory. Richard de Burgh
built his own position methodically rather than by outright conquest,
marrying into the local nobility, securing royal grants confirming his
claims, and gradually converting a role as an Irish king's indispensable
ally into direct lordship over most of the province. By the time his
family's hold on Connaught was fully secured, the de Burghs held not
only that earldom but, through the same generations, the earldom of
Ulster as well - two of the largest Anglo-Norman territorial blocks in
Ireland, controlled by a single family whose founder had begun as one
lord among many competing for influence at an Irish king's court.

A peak the lordship would not reach again
By the last decades of the thirteenth century, Anglo-Norman lordship
stretched, in some form of overlordship or direct control, across most
of the island - Leinster under royal administration, Munster divided
between the Butlers and the Geraldines, Ulster and Connaught under the
de Burghs, with only the most remote and mountainous Irish-held
territories remaining fully outside the reach of English law and
English lords. It was the widest extent the lordship would ever
achieve. The murder of the last de Burgh Earl of Ulster in 1333 - by
his own Anglo-Norman kinsmen, in a killing that fractured the earldom
and pushed many of his own family into adopting Irish custom rather
than defending English lordship - marked the point from which the
territory so painstakingly assembled began, permanently, to contract.
A Scottish king of Ireland
contractionDrafted from Orpen, 4 vols (1911-1920)
Edward Bruce, brother of Robert the Bruce of Scotland, landed in
Ulster in 1315 at the invitation of Irish lords hoping to use Scotland's
own war against England as cover for a rising against the colony
closer to home. The Earl of Ulster's forces were routed at Connor that
September, and for the next three years Bruce's presence turned
loosely connected local grievances into something closer to a general
war against English rule across much of the island.
Towns burned from Sligo to Athlone
The fighting spread well beyond Ulster. In Connaught, rival claimants
to the kingship there took Bruce's invasion as their own opportunity,
burning English towns and castles from Sligo to Athlone under his
encouragement, while in Thomond the Anglo-Norman lord Richard de Clare
found the local Irish dynasty he had depended on switching allegiance
to the invaders. No part of the English colony could simply wait the
crisis out; garrisons and settlers across the country found themselves
drawn into a conflict none of them had chosen.
Faughart
The invasion ended, after three years that left much of the colony
devastated, at the Battle of Faughart near Dundalk in October 1318.
English forces broke the Scottish line in a single rush; Edward Bruce
himself was found dead beneath the body of an English knight named
John Maupas, and the leader who brought his head to the king, John de
Bermingham, was made Earl of Louth for it. The immediate danger ended
with Bruce's death, but the colony that survived him was not the one
that had existed three years before - poorer, more exposed, and
considerably less confident that English rule in Ireland was
permanent.

A silk fringe on every helmet
contractionDrafted from Bagwell, 3 vols (1885-1890)
By the last decades of the fifteenth century, the lordship the
Statutes of Kilkenny had tried to wall off from Irish influence had
shrunk to a fortified enclave around Dublin, the Pale, defended by a
brotherhood of thirteen landowners with barely two hundred paid
soldiers between them. Real power over what remained of English
Ireland belonged, for most of two generations, to a single family: the
Earls of Kildare.
A house too useful to remove
Under Edward IV and Richard III, the House of Kildare eclipsed its old
rival the Butlers so completely that the crown found it simpler to
govern through the Fitzgeralds than around them. Successive kings
confirmed Kildare earls as viceroy or deputy governor not because
London trusted the family, but because no one else could hold the
lordship's shrunken territory together as cheaply or as effectively.
The arrangement suited Kildare as much as the crown: the earls
governed Ireland largely as they pleased, answerable to a king an
ocean away who had neither the money nor the inclination to install a
rival administration.
A young man given a naked sword
That arrangement ended in 1534, when the ninth Earl, summoned to
London to answer charges of misgovernment, handed the sword of his
own deputyship to his twenty-year-old son and heir, Thomas Lord
Offaly - advising him to be guided by older, cooler heads among his
own kinsmen. The advice went unheeded. A false rumor reached Dublin
that the old earl had been executed in the Tower, and his son,
convinced his father was already dead, resolved on open rebellion
before the truth could catch up with him. On St Barnabas's Day he rode
into Dublin at the head of a hundred and forty armed retainers, each
wearing a fringe of silk on his helmet - the flourish that gave him
the name by which he has been remembered ever since, Silken Thomas.
Interrupting a meeting of the royal council at St Mary's Abbey, he
publicly renounced his father's office and threw down the sword of
state, ignoring the Archbishop of Dublin's own tearful warning that
"they are not yet born that shall hereafter feel the smart of this
uproar." His cousin Lord Butler, offered a share of Ireland in exchange
for joining the revolt, refused in writing, declaring he would rather
die Thomas's enemy than live as his partner.

An eclipse the family did not recover from
Silken Thomas held the field against royal forces for over a year,
laying siege to Dublin Castle and rallying Irish allies to his cause,
but the rebellion collapsed once an English army under Skeffington
arrived in strength. He surrendered in 1535 on a promise of mercy that
the crown did not honor: after an act of attainder stripped him of his
title, he and five of his uncles were taken to Tyburn in 1537 and
executed together, ending the Kildare ascendancy in a single afternoon.
The rebellion's real casualty was the whole system of governing
Ireland through a semi-independent Anglo-Irish magnate family. Henry
VIII drew the obvious lesson: within a few years the crown would
govern Ireland directly, through English-appointed deputies backed by
an English garrison rather than through any Irish family's own private
loyalty - the change of policy that led, by 1541, to Henry claiming
not merely to be Ireland's lord but its king.
A law against marrying the neighbours
contractionDrafted from Bagwell, 3 vols (1885-1890)
By the 1360s the gap between how much of Ireland the English crown
claimed and how much it actually governed had grown too wide to
ignore. Lionel of Clarence, sent as viceroy and married into the
earldom of Ulster, found even the country immediately around Dublin
difficult to hold - his own soldiers cut off by local raiders more
than once - and spent much of his time in England rather than in the
lordship he had nominally come to strengthen. In 1367 he returned to
summon a parliament whose enactments gave legal recognition to a
reality that had been building for decades.

Naming the Pale by not yet naming it
The Statute of Kilkenny drew a formal line between shires still
answering reliably to English law and territory beyond it - ten
counties required to render account at Dublin, others excused
altogether because of distance. The word "Pale" itself would not come
into use for another century, but the statute's own text already
described exactly the thing that word would later name: a narrow,
defended core of English government surrounded by land the crown no
longer administered directly.
Treason defined as intermarriage
The statute's substance went well beyond administrative boundaries. It
recited that the English in Ireland had once spoken English and lived
as Englishmen, but that many had since adopted Irish language and
custom to the crown's own detriment - and it made marriage, fosterage,
or even friendly social bonds with the Irish into acts of high treason
for the colonists still living inside the shrinking zone of direct
rule. Englishmen were required to keep English names, English dress,
and the English tongue on pain of forfeiture. That such a law needed
writing at all was itself the clearest evidence of how far the
colony's own assimilation into the country it ruled had already gone.
Risen again from death to life
endDrafted from Bagwell, 3 vols (1885-1890)
By 1541 the title Henry II had claimed at Waterford three hundred and
seventy years earlier - Lord of Ireland, granted in the shadow of a
papal bull - had come to look like a liability rather than an honour.
Friars sympathetic to Rome had spent years encouraging the idea that
the English crown's own authority in Ireland was merely delegated from
the pope, a notion the recent break with Rome in England made
considerably more awkward than it had once been.

A parliament that voted itself out of one name
Anthony St. Leger, the king's deputy, summoned a parliament to Dublin
that summer, attended by the Anglo-Irish peerage and, unusually, by a
number of Gaelic lords as observers or agents. On the appointed day a
bill declaring Henry VIII King of Ireland, rather than merely its
lord, was read aloud in both English and Irish, to what the record
calls general acclamation. It passed its three readings the same day
and was sent to the Commons, where it passed just as quickly; the
Lords, St. Leger noted, subscribed it at once, "lest they should
thereafter be tempted to deny their consents."
What a change of title actually settled
St. Leger himself, writing to the king afterward, described the honour
of presiding over the change as being no less to his own comfort than
"to be risen again from death to life." The language was not simply
flattery. The new royal title answered, at a legal and symbolic level
at least, the very question the friars had been raising - that English
authority in Ireland rested on the pope's grant and could therefore be
dissolved by the pope's displeasure. A kingdom, unlike a lordship,
claimed no such derivative status. The unanimous vote that created it
settled nothing about how much of Ireland the crown actually governed,
which remained, as it had for two centuries, considerably less than
the whole island - but it closed, on paper at least, an argument about
where that authority had come from in the first place.
Succession
What led here
1171Lordship of Irelandoverthrewthe Kingdom of Leinster under Diarmait Mac Murchada
Diarmait, restored to his own throne with Anglo-Norman help before his death in 1171, had already agreed that Strongbow would inherit Leinster through marriage to his daughter Aoife; Henry II's own arrival that same year folded the whole enterprise into a royal lordship before Strongbow could rule it as an independent kingdom in his own right.
No conquest or change of ruler separates the two records: an Irish Parliament voted Henry VIII King of Ireland in place of Lord of Ireland, and the same crown administration continued under the new style.
