Henry II returns to England on April 17, 1172, having granted a charter to Dublin, the first granted to an Irish town.

Toward the end of 1171, Henry II, the first king of England to set foot on Irish soil, lands at Crook, County Waterford. His visit to Ireland serves two purposes. Firstly, it allows him to bring his adventurous English barons to heel and put the royal seal on their conquests in Ireland. Secondly, it means he can avoid meeting the cardinal legates who have been dispatched from Rome to investigate his complicity in the murder of the Archbishop of Canterbury, Thomas Becket, in 1170.

When the King of Leinster, Diarmait Mac Murchada, finds himself exiled in the late 1160s, he quickly finds help across the Irish Sea. He finds Henry II on the banks of the Loire in 1166 and is then pointed in the direction of south Wales by a Bristol merchant to find Richard FitzGilbert de Clare, more commonly known as Strongbow, who is then out of royal favour due to his prior support of Henry II’s competition for the kingship, Stephen of Blois.

Bolstered by English forces, Diarmait returns to Ireland and retakes his kingdom with Strongbow’s help, the latter earning the hand in marriage of Diarmait’s daughter, Aoife, in return. None of this has greatly concerned Henry II, until Diarmait dies, and Strongbow seizes the Kingdom of Leinster for himself in 1171. Leinster encompasses not only the counties of Carlow, Kilkenny, Wexford, Kildare, and parts of Wicklow, Laois, and Offaly, but the kings of Leinster are often the overlords of the flourishing Hiberno-Norse ports of Wexford and Dublin, both of which have considerable trading links with England and wider Europe.

Concerned with the growing power of Strongbow in Ireland, Henry II decides to head across the Irish Sea. He originally intends to arrive in Ireland in September 1171, but unfavourable winds on the coast of southwest Wales delay his journey for 17 days. He finally embarks from Pembroke on October 16 and arrives on the County Waterford coast the following day.

Naturally, Henry does not come alone and is at the head of an estimated 4,000 strong army comprised of 500 knights and their esquires and a large body of archers, all of which are carried, along with horses, in 400 ships. The undertaking is vast, and a large quantity of supplies are gathered to provision this considerable force. These ingredients include salted meats and fish, 1,000 lbs. of wax to ensure that Henry can seal charters and mandates, and, of course, the oil on which the medieval war machine runs, wine.

With the arrival of Henry II in Ireland, Strongbow surrenders the kingdom of Leinster and the Hiberno-Norse towns of Dublin, Wexford, and Waterford. Henry II regrants Leinster to Strongbow as a lordship, and later grants him Wexford. However, Waterford and Dublin become, and remain, royal ports.

Henry II then tours Ireland, showing the clergymen and native kings who their new lord is. He first visits Lismore and Cashel, then back to Waterford for a brief rest, before journeying by way of Kilkenny to Dublin, where he arrives around November 11. At all of his stop he collects the submissions of the Irish kings, with the probable exception of Ruaidrí Ua Conchobair (Rory O’Connor), who is the claimant to the high kingship of Ireland at the time.

Outside the city walls of Dublin, Henry II constructs a palace at the present-day southern side of Dame Street, where he celebrates the winter festivities until February 2. At this time, he also grants Dublin its first charter, on a piece of parchment measuring only 121 x 165 mm, which, extraordinarily, survives to this day. Henry’s charter to Dublin grants the right to live in the city to the men of Bristol, with whom the men of Dublin have enjoyed pre-existing economic relations.

About March 1, 1172, Henry II makes his way to Wexford, before finally departing for England on Easter Sunday, April 17, after celebrating Mass. It is probable that he had intended to stay in Ireland longer than he did, but events in England and Normandy divert his attention. In Normandy, Henry II’s son, Henry, has gone into rebellion against his father, while in England, the cardinal legates are threatening to interdict Henry’s lands unless he comes to meet with them regarding Becket’s murder.

The circumstances which lead to Henry II’s departure are more telling for Ireland’s future than any member of contemporary society could have realised. Now, Ireland has to compete with the other segments of a vast transnational realm, with lands stretching across England, Wales and France. Although Henry II is the first king of England to arrive in Ireland, his visit does not mean that royal visits would become a routine occurrence. Throughout the Middle Ages, the kings of England only directly visit Ireland in 1185, 1210, 1394–5, and 1399. As such, Henry’s visit and departure marks the beginning of absentee lordship over Ireland.
