The Expugnatio Hibernica, or The Conquest of Ireland, is a medieval historical narrative by Gerald of Wales on the twelfth-century Anglo-Norman invasion of Ireland. Completed in , a second recension was issued .

It was a popular medieval work and survives in thirty-six manuscripts, most in Latin but some in English and Irish. It was first published, abridged, in the 1577 edition of Holinshed's Chronicles and then in full in the 1587 edition. A 1602 publication by William Camden brought it to wider attention and triggered broad attacks on its veracity by Irish apologists who considered it a concoction of lies, though modern scholarship is more nuanced in its assessment.

Though a flawed work, biased towards Gerald's family and against the Irish, it is considered the main source regarding the invasion and one of the most important works for the history of medieval Ireland.

Background In 1166 Diarmait Mac Murchada, the king of Leinster, was driven into exile by Tigernán Ua Ruairc and his allies. With the permission of Henry II Diarmait sought allies in England and Wales and in 1169 returned to Ireland with a force of Cambro-Norman adventurers, joined the following year by Richard de Clare.

Diarmait died in 1171 and de Clare claimed Leinster through marriage to Diarmait's daughter Aoife, causing Henry II to fear he might establish an autonomous lordship. Henry landed in Ireland in late 1171 to assert royal authority, receiving submissions from Irish rulers and the leading Anglo-Norman captains, but fighting and settlement continued after his departure; the events of the 1170s and 1180s formed the immediate background for Gerald's account of the invasion and early colony.

Gerald of Wales Gerald of Wales was a scholar and churchman, born to a mixed Norman and Welsh family among the marcher gentry of South Wales. He studied in St Peter's Abbey in Gloucester before moving to Paris where he studied the trivium.

After this first period in Paris he returned to Wales, where in 1176 he sought election to the see of St Davids but due to Henry II's opposition was unsuccessful despite the support from the monks. He then returned to Paris for about three years, until , where he studied canon law and theology, lecturing on the former.

In February 1183 he visited Ireland with his cousin, Philip de Barry, and stayed for about a year. After returning and at the urging of Henry II, he reluctantly accepted the position of royal clerk. He returned to Ireland for another year around April 1185 with Henry's son, John Lackland. He used his time in Ireland to gather material for both the Expugnatio Hibernica and the Topographia Hibernica, issuing the Topographia .

Composition and textual history Traditionally referred to as the Expugnatio Hibernica, or the Conquest of Ireland, the work has several names. Gerald referred to it as the Expugnatio Hibernica and the Vaticinalis historia, or The Prophetic History. He also combined the two names, calling it the Vaticinalem Hybernicae expugnationis Historiam or The Prophetic History of the Conquest of Ireland in a 1218 letter sent to the canons of Hereford Cathedral.

Written in Latin, the Expugnatio Hibernica is a historical narrative but can also be seen as a family epic that promotes the marcher lords who led the initial expedition to Ireland, including Gerald's family. Two recensions were issued, α in and a much revised β likely . Historically, there was some dispute over the authorship of β but modern scholars generally accept it as Gerald's work.

Date and circumstances of composition Scott and Martin argue that the first recension was completed in the summer of 1189, after the death of Henry II but before the coronation of Richard I. This is based on "Pictavensium comes inclite, Normannorum quoque dux et Anglorum rector mox future", or "Renowned Count of Poitou, also Duke of the Normans, and soon-to-be ruler of the English" appearing in the preface, as it would be insulting to Henry II if it appeared before his death, but inaccurate if it appeared after the coronation of Richard. Gerald tells us that the work took two years to complete, though Scott and Martin argue based on the body of the work that he began in early summer 1188.

Dedication and purpose Gerald dedicated the first recension to Richard, count of Poitou, later King Richard I, and the second recension to King John. Like the Topographia Hibernica, Gerald wrote the Expugnatio Hibernica in part as an attempt to obtain patronage, possibly to gain an English bishopric, as well as to argue that his extended family deserved greater rewards for their participation in the conquest than they had received. In his autobiography he said that he wrote the Expugnatio and Topographia "that he might at least by his own labour win some profit or conquest".

He was also committed to the subduing of Ireland and sought to use the Expugnatio Hibernica and the Topographia to justify English invasions of Ireland and to glorify its conquerors. He later used it to encourage further military expeditions there, pressing King John in a 1209 letter accompanying a copy of the Expugnatio Hibernica to return.

Recensions and authorial revision Gerald was a "fastidious" stylist and continued to modify the text for years after first writing it. These revisions are divided into two recensions, α and β. α represents the original text and copies with lesser modifications, and β follows a far more extensive reworking of the text. It is unknown when β was issued, but Scott and Martin as well as Amelia Sargent suggest a date around 1209, based on a quotation from the β recension that Gerald included in a letter he sent to King John.

Between α and β there are several intermediate manuscripts which show the evolution of text. In the earliest versions of α Gerald uses arcarii, while in later manuscripts he uses arcarii equestres before settling on satellites equestres. In the earliest versions of α he uses stadia when providing distances, while in later manuscripts he uses a mix of stadia and miliaria or milia passuum and in the β recension he consistently uses miliaria or milia passuum.

Other modifications go beyond stylistic. The description of Robert FitzStephen is enhanced, adding that he was "only slightly above average in height", and alters the account of Raymond FitzGerald to say that upon succeeding his uncle FitzStephen he restored peace following the 1188 Desmond Insurrection "only in part".

The most substantial differences are in the inclusion of prophecies and the papal privileges. α includes two papal privileges, from Pope Adrian IV and Pope Alexander III, granting King Henry II dominium over Ireland, while β omits the privilege from Alexander III.

β also excluded many of the prophecies relating to Merlin, and a third distinction, which Gerald mentioned in the α recension and would have contained further details of prophecies, was never published. It is likely that the initial reason for not issuing the third distinction was out of a desire to avoid offending Henry II, as Gerald's interpretation would not be favourable to him. However, this reason ceases to apply after the death of Henry II and it is unlikely that Gerald, who described Henry II as a "tyrant" in De principis instructione, would have felt a need to continue to suppress the work.

Scott and Martin propose two alternative theories for these excisions and continued suppression. Either Gerald's faith in the prophecies waned over the years between α and β, or he lost the underlying sources and was unwilling to issue works without reference to them. They consider the first theory more probable and Sargent concurs, arguing that Gerald removed them as part of a reconception of the project, to revise his expectations of what constituted a successful conquest of Ireland, and to encourage King John to return and complete the conquest.

Gerald also added two chapters to Expugnatio Hibernica as part of β. The first regarding a vision seen by Henry II at Cardiff, and the second regarding the 1170 synod at Armagh. These chapters are also included in De principis instructione, and the first is included in Itinerarium Kambriae.

Contents The Expugnatio Hibernica provides a narrative of the Anglo-Norman invasion of Ireland until 1189 and the origin story of the twelfth-century Norman colony. Originally divided into three distinctions, the third was never issued.

Gerald describes the first distinction as containing "the account of the exile of Diarmait and his restoration by Henry II, King of England". It covers: The exile of Diarmait The arrival of FitzStephen and the capture of Wexford and Osraige The alliance of the Irish princes against Diarmait and his Norman allies The arrival of Maurice FitzGerald and the capture of Dublin The arrival of Raymond and Earl Richard and the capture of Waterford The arrival of King Henry II and the submission of princes of Ireland The rebellion of King Henry's sons

He describes the second distinction as containing "the account of the return of the earl to Ireland, sent by the King of England, and of Raymond's reinstatement as the commander of the garrison". It presents eight sections of narrative:

The activities of Richard de Clare and Raymond le Gros between 1173 and 1175 The capture of Limerick The relief of Limerick and the death of le Gros John de Courcy's expedition to Ulster Various events in Ireland in 1177 Events involving Hugh de Lacy from 1181 to 1185 John Lackland's 1185 expedition to Ireland Events in 1185 and 1186

The accounts in these sections become more compressed as they progress. Gerald justifies this by saying that he was preoccupied preparing for a crusade, though Scott and Martin suggest he may have simply been eager to complete the work.

Two papal privileges claimed to support English dominium over Ireland, Laudabiliter et satis issued by Adrian IV and Quoniam ea issued by Alexander III, are included in chapters five and six of this distinction alongside a defence of the English legal right to Ireland.

Themes and rhetoric A recurrent theme of the Expugnatio Hibernica is Gerald's praise of his family's achievements in Ireland, and he uses the work both to celebrate their actions and to argue that they deserved greater rewards.

This celebration of Gerald's ancestors results in uneven treatment of the individual Anglo-Norman leaders, with some of those unrelated to him treated with a clear hostile slant. Scott and Martin point to his portrayal of Hervey de Montmorency and William FitzAldelm as cases where "one feels that whatever they do will be given a sinister slant by Gerald".

He also presents some of his relatives, especially Raymond le Gros, as "larger than life", and this comes at the expense of Richard de Clare whose role in the endeavour is diminished.

O'Leary describes it as a "political work", setting out both how Ireland should be conquered and governed, and connecting military success to questions of authority and royal policy. Gerald presents the king as the source of lawful rule, but he also criticises parts of royal intervention in Ireland and argues that conquest would have proceeded further without it. He contrasts the antiqua militia, the "old soldiers", with later arrivals and uses this contrast to frame disputes over leadership and reward.

Gerald's depiction of the Irish relies on hostile ethnographic stereotyping. He describes them as barbarous and treacherous and attributes economic conditions to idleness while allowing only a limited set of positive qualities, including musical skill and clerical chastity. Gerald also uses language of subjugation and "ordering", including the phrase "in formam simul et normam redacta" in support of bringing the Irish into a "disciplined" state.
