The gallowglass (also spelt galloglass, gallowglas or galloglas; from Irish: gallóglaigh) were a class of elite mercenary warriors who were principally members of the Norse-Gaelic clans of Scotland between the mid 13th century and late 16th century. As Scots, they were Gaels and shared a common background and language with the Irish, but as they had intermarried with the 10th century Norse settlers of western Scotland, the Irish called them Gall Gaeil ("foreign Gaels").
Large numbers of gallowglass septs settled in Ireland after being dispossessed of their lands in Scotland for choosing the wrong sides in the Wars of Scottish Independence. The first and probably most famous of these were the MacSweeneys, (who unlike most were said to be of native Irish ancestry) settled originally by the O’Donnells in west Donegal. These were followed by MacDonnells, MacCabes and several other groups settled by powerful Irish nobles in different areas. The gallowglass were attractive as a heavily armoured, trained aristocratic infantry to be relied upon as a strong defence for holding a position, unlike most Irish foot soldiers, who were lower class and less well armoured than the typical Irish noble who fought as cavalry. In time there came to be many native Irish gallowglass as the term came to mean a type of warrior rather than an ethnic designation.
They were a significant part of Irish infantry before the advent of gunpowder, and depended upon seasonal service with Irish chieftains. A military leader would often choose a gallowglass to serve as his personal aide and bodyguard because, as a foreigner, the gallowglass would be less subject to local feuds and influences.
The term is an anglicisation of the Irish gallóglaigh (lit. "foreign young warriors"), with the English plural -s added to the end. The singular of gallóglaigh is gallóglach. The word óglach comes from Old Irish oac (meaning "youth") and Old Irish lóeg (meaning "calf" but later becoming a word for a hero). Encarta specifies the plural of gallowglass to be "gallowglasses", but this article assumes that the singular and plural terms are both "gallowglass", as the English term comes from an Irish plural. Shakespeare uses the form "gallowglasses" in the play Macbeth.
The first record of gallowglass service was in 1259, when Aedh Ó Conchobair, King of Connacht, received a dowry of 160 Scottish warriors from the daughter of the King of the Hebrides. They were organised into groups known as a "Corrughadh", which consisted of about 100 men. In return for military service, gallowglass contingents were given land and settled in Irish lordships, where they were entitled to receive supplies from the local population.
In 1569 Turlough O'Neill married Lady Agnes MacDonald of Kintyre. Her dowry consisted of at least 1200 galloglass fighters. Along with two young men as support and friends on top to assist or fight this could easily have numbered over 5,000 current and future Gallowglass coming into the area.
By 1512, there were reported to be fifty-nine groups throughout the country under the control of the Irish nobility. Though initially they were mercenaries, over time they settled and their ranks became filled with both Scots-Norse and many native Irish men.
They were noted for wielding the massive two-handed sparth axe (a custom noted by Geraldus Cambrensis to have derived from their Norse heritage) and broadsword or claymore ("claidheamh mór"). For armour, the gallowglass wore mail shirts over padded jackets and iron helmets; he was usually accompanied by two boys (like a knight's squires), one of whom carried his throwing spears while the other carried his provisions.

The importation of gallowglass into Ireland was a major factor in containing the Anglo-Norman invasion of the 12th century, as their ranks stiffened the resistance of the Irish lordships. Throughout the Middle Ages in Ireland, gallowglass troops were maintained by Gaelic Irish and Hiberno-Norman lords alike. Even the English Lord Deputy of Ireland usually kept a company of them in his service. (See Also: Norman Ireland)
In a paper entitled "A Description of the Power of Irishmen", written early in the 16th century, the Irish forces of Leinster are numbered at 522 horse, 5 battalions of gallowglass (gallóglaigh) and 1432 kerne, and those of the other provinces were in like proportion. Mac Cárthaigh Mór commanded 40 horse, 2 battalions of gallowglass, and 2000 kerne; the Earl of Desmond 400 horse, 3 battalions of gallowglass, and 3000 kerne, besides a battalion of crossbowmen and gunners, the smaller chieftains supplying each their quota of men.
In 1517, "when the reformacion of the countrye was taken in hand," it was reported that the Irish forces in Thomond were 750 horse, 2324 kerne, and 6 "batayles" of gallowglass, the latter including 60 to 80 footmen harnessed with spears; each of these had a man to bear his harness, some of whom themselves carried spears or bows.
Every kerne had a bow, a 'skieve' or quiver, three spears, a sword, and a skene (Irish scian or Scottish Gaelic sgian), each two of them having a lad to carry their weapons. The horsemen had two horses apiece, some three, the second bearing the 'knave' or his attendant.
The 16th century in Ireland saw an escalation in military conflict, caused by the Tudor conquest of Ireland. Gallowglass fighters were joined by native Irish mercenaries called buanadha (literally "quartered men") and by newer Scottish mercenaries known as "redshanks". The flow of mercenaries into Ireland was such a threat to English occupation that Queen Elizabeth I took steps against them in 1571 – around 700 of them were executed after the first of the Desmond Rebellions.
Despite the increased use of firearms in Irish warfare, gallowglass remained an important part of Hugh Ó Neill's forces in the Nine Years War. After the combined Irish defeat at the Battle of Kinsale in 1601, recruitment of gallowglass waned, although Scottish Highland mercenaries continued to come to Ireland until the 1640s (notably Alasdair Mac Colla). They fought under the Irish General Eoin Roe O'Neill at the Battle of Benburb when O'Neill had an overwhelming victory in 1646. The Gallowglass of the Mac Cárthaigh Riabhaigh are recorded as having attacked Mallow in County Cork as late as 1645.
Images of Gallowglass fighting as mercenaries in European mainland armies were sketched by Dürer in 1521 and later by French and Dutch artists. Gallowglass served in the Dutch Blue Guards, Swiss Guard, The French Scottish Guard and the forces of King Gustav Adolphus of Sweden in his invasion of Livonia during the Thirty Years War.
