Irish military diaspora
The Irish military diaspora refers to the many people of either Irish birth or extraction who have served in overseas military forces, regardless of rank, duration of service, or success.
Many overseas military units were primarily made up of Irishmen and had the word 'Irish', an Irish place name or an Irish person in the unit's name. 'Irish' named military units took part in numerous conflicts throughout world history. The first military unit of this kind was in the Spanish Netherlands during the Eighty Years' War between Spain and the Dutch. A notable example is that of Owen Roe O'Neill.
Australia and New Zealand
The British colonies of Australia and New Zealand suffered a series of 'war scares' during the 19th century from perceived threats from France and Russia. In 1870, when the last British troops left, defence became the responsibility of locally raised colonial forces.New Zealand
The first Irish unit formed was in New Zealand - the Christchurch Royal Irish Rifle Volunteers were gazetted on 18 November 1868, re-designated No. 2 Company Christchurch R.V. on 4 April 1871, and then disbanded on 11 August 1874.On 29 April 1885, a meeting was held in Christchurch, New Zealand and 95 members of the Irish-community applied to form an Irish volunteer corps. That was accepted on 30 April 1885 as the Canterbury Irish Rifle Volunteers.
On 1 June 1892, they were amalgamated with the Sydenham R.V. to form the Christchurch City R.V., gazetted 22 July 1892.
New Zealand's Dunedin Irish R.V. were formed 7 May 1885, when 189 men offered their services. The Dunedin Irish R.V. became part of the 1st Battalion Otago R.V. on 25 January 1886, and were disbanded on 13 September 1893.
One other Irish Corps was to be formed in the South Island of New Zealand, the Southland Irish R.V., were formed at Invercargill and accepted 10 June 1885 as an Honorary Corps. On 7 August 1885, it applied to be formed into a Garrison Corps and then being disbanded on 9 July 1886.
Another N.Z. Irish corps was proposed during a 'war scare' in 1885, the Temuka Irish Rifles, on 13 June 1885, but the proposal was abandoned when the government deemed it improbable that hostilities would ensue.
Another Irish corps was proposed on 3 April 1887, and was accepted 24 June as the Auckland Royal Irish R. V. On 13 August 1887, they were posted to the 3rd Battalion Auckland R.V. When inspected on 6 October 1889, they had a total strength of 93 officers and men and they were disbanded on 5 March 1892.
The last Irish Corps to be formed in New Zealand was the Irish R.V., accepted 22 October 1901. They were attached to the 2nd Battalion Wellington R.V. and 'J' Company, formed 16 April 1902, becoming 'I' Company on 1 November 1904.
The N.Z. Defence Act of 1911 saw an end to the volunteer system, the Wanganui Irish were absorbed into the new territorial system when the 2nd Battalion Wellington R.V. were re-designated, 7th Regiment on 17 March 1911.
An Irish Caubeen was worn by the Nelson, Marlborough, and West Coast Regiment, which came about after a regimental-alliance with the Royal Irish Fusiliers, which took place on 23 September 1949. The blue caubeen and green hackle of the Royal Irish Fusiliers, was formally presented to the NMWC Regiment at a Barrosa Day parade in 1961 but may have been worn on special anniversaries and parades before that. On 24 January 1964, the Ist Battalion Nelson, Marlborough, and West Coast Regiment amalgamated into the, 2nd Battalion Royal New Zealand Infantry Regiment. N.Z. Army Headquarters ruled that only "A" and "B" Companies of the new regiment were to wear the caubeen and hackle on dates significant to the regiment. That was found to be unworkable and so the caubeen and hackle were not worn until 1968, when the ruling was changed. Only officers and warrant officers seem to have worn the caubeen during formal parades, and the RNZIR cedar green beret was worn for everyday use. By the early 1990s. all ranks were wearing the caubeen and hackle. On the formation of the Royal Irish Rangers in 1969, the green caubeen of the Irish Rangers was adopted by the New Zealanders. The 2RNZIR discontinued wearing the caubeen in the 1990s due to financial constraints, and it was replaced by the cedar green beret. In November 1998, the NZ mounted-rifles "lemon-squeezer" hat was introduced army wide, and was worn for formal parades, while the beret was worn for everyday use. In 1999, the rifle green beret was adopted for the New Zealand army and was phased-in in late 2002. The 2nd Battalion Group, as the unit was known then, wore the green hackle on the left side of the mounted rifle hat. That was to signify the continued association with the Royal Irish Regiment.
Australia (pre-Federation)
Queensland
An offer to form an Irish Corps in the British colony of Queensland, Australia, had been rejected in 1862.Eighteen years after the formation of the first Irish Corps in New Zealand, a Queensland Irish Volunteer Corps were proposed on 18 February 1887, and gazetted 24 February 1887 as 'A' Company Queensland Irish Rifle Corps.
Established at Peel Street, South Brisbane with three officers and 100 other ranks, 'B' and 'C' companies quickly followed, formed on 11 March 1887 at Valley, North Brisbane and on 22 March 1887 at Petrie Terrace, West Brisbane.
'D' Company was formed at Gympie on 14 November 1888 with an establishment of three officers and 90 other ranks. The application to form this unit had been submitted on 27 May 1887. The application to form a company at Ipswich was submitted 26 August 1889. They were gazetted on 4 September 1889 as 'E' Company and had a strength of three officers and 90 other ranks.
Gazetted the same day were 'F' Company established at Woollongabba, East Brisbane with three officers and 90 other ranks.
The final company raised was 'G' Company at Maryborough and again with three officers and 90 other ranks, on 4 December 1889.
An application in March 1887, signed by over 100 men willing to form an Irish Corps at Rockhampton came to nothing.
'G' Company at Maryborough was the first to disband on 6 August 1891, followed by 'D' Company at Gympie on 7 November 1894.
In a re-organisation during 1896, the Queensland Irish Volunteer Corps were designated 3rd Battalion, Regiment of Queensland Rifles and 'A', 'B', 'C', 'E' and 'F' companies became 'I','J', 'K', 'M', and 'N' companies. On 30 July 1897, 'I', 'K', and 'M' Companies were disbanded; 'L' and 'N' companies were disbanded by August the following year, and this brought to an end the Volunteer Corps in Queensland.
New South Wales
In November 1895, a meeting was held in Sydney Town Hall when it was decided to form an Irish Rifle Corps.These companies were established and gazetted on 5 March 1896, as the New South Wales Irish Rifles. They were grouped together with St George Rifles and the Scottish Rifles to form an administrative regiment, designated the 5th New South Wales Infantry Regiment on 20 June 1896. Another Irish company was formed in Sydney in 1998.

For administrative purposes, two non-Irish companies from the Illawarra district were attached.
A further Irish Company was formed at Newcastle, the men being sworn in in June 1900.
Twenty-three men of the 8th fought in the Boer War.
The 8th Union Volunteers Infantry Regiment was re-designated NSW Irish Rifle Regiment in 1903, and then became the 1st Battalion NSW Irish Rifle Regiment in 1908.
A major re-organisation in 1912 saw the name change to 33rd Infantry Regiment and, in yet another re-organisation in 1918, changed to the 55th Battalion.
In 1927 the old NSW Irish Rifles title was revived. The 'Irish connection' finally came to an end in 1930, when the regiment was re-designated as the NSW Rifle Regiment.

South Australia
The South Australian Register, dated 13 February 1900, carried the following public notice: "A meeting of all interested in the formation of an Irish Rifle Corps will be held on Tuesday 20 February at 8pm in the town hall."Afterwards 157 names of volunteers were taken, and after selection, were to become 'F' Company, 1st Battalion Adelaide Rifles. At the formation of the Irish Company, it was suggested that a green uniform be worn, but no distinctive uniform was adopted. although a shamrock worked from black braid was worn on the uniform sleeves, and hand-engraved brass harp collar badges were worn. They were worn until January 1910, when the company was ordered to discontinue wearing them, which they did under protest. That was done to secure uniformity of dress with the other companies in the 10th AIR. A green stripe an inch wide was also approved to be worn on the trouser seams, but was later disallowed.
Victoria
Attempts had been made to form other Irish Corps. A five hundred strong Irish Australian Volunteer Corps was proposed in Melbourne Victoria in April 1885. A number of meetings were held at St. Patrick's Cathedral Hall.Australia (post-Federation)
With the formation of the Australian Commonwealth military forces in 1903, the Adelaide Rifles became part of the newly-formed 10th Australian Infantry Regiment. That had been the last Irish unit to be formed in Australia.Steps were also taken in May 1901 and May 1910, to form an Irish Australian Regiment in Melbourne, and again in 1941. An Irish Volunteer Corps was proposed at a meeting held in the dining rooms of the Shamrock Hotel, in Perth Western Australia on 18 April 1900. Another Irish corps was proposed in Perth in 1904. An Irish regiment was suggested at Bendigo Victoria in April 1906, and a company of Irish Rifles was considered at Broken Hill NSW in April 1910. An Irish corps was also proposed in Queensland, as part of the 9th Australian Infantry Regiment in 1906. Committees were often appointed, but the corps were never formed.
The 4th Battalion, Royal Australian Regiment ; an infantry battalion formed on 1 February 1964, and renamed the 2nd Commando Regiment on 19 June 2009. 4 R.A.R. is affiliated with Britain's 4th Regiment of Foot Guards. The 4 R.A.R. regimental band use the same uniform as the Pipes and Drums of the Irish Guards. The 4 R.A.R. battalion subsequently served in Malaysia as part of the Far East Strategic Reserve from August 1965 to September 1967, and seeing active service in Borneo against the Indonesian army during the Indonesia-Malaysia confrontation. The battalion began its first 12-month tour of Vietnam on 1 June 1968, returning to Vietnam for its second tour in May 1971. From 1990 to 1993 many individual soldiers from the battalion served with the United Nations in Cambodia. In 1993, soldiers from the battalion were detached for operational service in Somalia. In May 1993, the battalion deployed troops to Cambodia. In 1994, the battalion deployed Rwanda. In 1996, a decision was made to convert 4 RAR to a special forces unit. On 1 February 1997, was renamed to 4 RAR. The unit conducted operations in East Timor and Iraq, and later lost soldiers killed-in-action during the war in Afghanistan.

Austria and Austria-Hungary
The Habsburgs were the principal employers of Irish soldiers in Central Europe. The multinational nature of the empire meant that gifted foreigners were always welcome and had opportunities not available in other Eastern and Central European countries. By one estimation, over 100 Irishmen were field marshals, generals, or admirals in the Austrian Army, with a corresponding number of men holding commissions in the lower ranks. The first Irishman of note to serve the Habsburgs was Colonel Richard Walsh of Carrickmines, Dublin, who was mortally wounded at the Battle of Lützen. His son Oliver became a Major-General. In all, eleven members of this family were field marshals or generals, the most notable being George Olivier, count of Wallis.Many Irishmen were Inhaber and held rank as regimental colonels. Jacob Butler is the first of these. A Walter Butler was an Inhaber of a dragoon regiment and received praise for his role in the defence of Frankfurt an der Oder. Butler was responsible for the assassination of the Bohemian general Albrecht von Wallenstein, who was in the process of defecting to the Swedes.
Another Irishman to serve as field marshal was Francis Taaffe, 3rd Earl of Carlingford. While attending the Jesuit college at Olomouc, he came to know Charles V, Duke of Lorraine, and this benefited his career greatly. He played a prominent role in saving Vienna in 1683 and in the subsequent conflict with the Turks. He later became a member of the Order of the Golden Fleece and served Charles V as his prime minister.
Maximilian Ulysses Browne was of the first generation born in Austria but was from a prominent Limerick family. Through his mother he was descended from the FitzGeralds, Earls of Desmond. Browne was a major-general by the age of 30. He rose to the rank of Generalfeldmarschall and died leading his men into battle during the Battle of Prague. Browne was a kinsman and mentor to Franz Moritz von Lacy who rose to be president of the Hofkriegsrat from 1766 to 1774. Other famous Irish-Austrian generals included William O'Kelly from Aughrim in Co. Galway; John Sigismund Maguire of Co. Kerry, who captured Dresden in 1758 and successfully defended it against Frederick the Great, who mentioned him on a number of occasions; and General Karl O'Donnell, was known for his exceptional conduct at the Battle of Torgau. Meanwhile, Colonel Hume Caldwell of Co. Fermanagh was noted for his conduct at Breslau and Olmütz, where he perished. Unusually, Caldwell was of Protestant origin. Field Marshal Laval Nugent von Westmeath was prominent during the Napoleonic Wars and was most noted for his role in the capture of Rome in 1815. In recognition of this, Pope Pius VI made him a prince in 1816. There were no Irish regiments in the Austrian Army with influence confined to nobility serving as officers.

Canada
The Irish Regiment of Canada in the Second World War was the only Canadian Irish unit to fight in any war. It also perpetuates the active service of the 1st Canadian Machine Gun Battalion from the First World War and the indirect service of the 190th Battalion, Canadian Expeditionary Force, and the 208th Battalion, CEF. Served as 1915 110th Irish Regiment; 1920 – The Irish Regiment; 1932 – The Irish Regiment of Canada; 1936 – The Irish Regiment of Canada ; 1940 – The Irish Regiment of Canada.The Irish Fusiliers of Canada perpetuated the First World War active service of the 29th Battalion, CEF plus the indirect service of the 121st Battalion, CEF and the 158th Battalion, CEF. Served as 1913 – 11th Regiment, Irish Fusiliers of Canada; 1920 – The Irish Fusiliers of Canada; 1936 – The Irish Fusiliers of Canada ; 1946 – 65th Light Anti-Aircraft Regiment ; 1958 – The Irish Fusiliers of Canada ; 1965 – placed on the Supplementary Order of Battle; 2002 – amalgamated with The British Columbia Regiment.
The Irish Canadian Rangers perpetuated the indirect service of the 199th Battalion Duchess of Connaught's Own Irish Rangers, CEF. Served as 1914 – 55th Irish Canadian Rangers; 1920 – The Irish Canadian Rangers; 1936 – disbanded.
The 218th Battalion, CEF lacks perpetuation. The colonel had Irish ancestry, but the largest group of its men were recent eastern European immigrants from the fringes of the Austro-Hungarian Empire who spoke Ukrainian but would have had Austrian citizenship. This combined with the 211th Battalion, CEF, to form the 8th Battalion, Canadian Railway Troops, which served in France building and maintaining railroads.

- The Princess Louise Fusiliers. Although the word "Irish" does not appear in the unit name, the "PLF" are designated as an Irish regiment. The blue Caubeen is an authorized headdress, and a grey hackle is worn with it and with the beret. Until relatively recently, officers also carried a blackthorn walking stick.

Papal States
The next significant engagement was the Battle of Castelfidardo where 150 Irishmen fought. The war ended shortly after this when the outnumbered and outequipped Papal army were ordered by Pius to lay down their arms.
Apart from Myles O'Reilly this was the first military experience of Myles Keogh who later on to fight with distinction during the US Civil War and after in the United States Cavalry until he fell at the Battle of Little Bighorn in 1876.
Portugal
- Marshal William Beresford, 1st Viscount Beresford; head of the Portuguese army from 1809 to 1820.
Russia
Irish military involvement in the Swedish army was neither happy nor successful. At the beginning of the seventeenth century about 6,000 men were shipped out of Ulster for the security of the plantation and sent to Sweden. They were especially unhappy fighting for a Lutheran power. Some Irish friars disguised themselves as soldiers and moved among the men encouraging them to desert to Catholic powers. The men then left Swedish service and most joined the army of Poland. After this incident Gustavus Adolphus refused to accept any large scale recruitment of Irishmen considering them untrustworthy. However a small number went to serve in the officer corps. The most prominent of these was Hugh Hamilton, 1st Viscount of Glenawly. Two of his nephews also entered Swedish service.

Spain
The next great exodus of Irishmen to serve in the armies occurred after the Siege of Kinsale. An Irish regiment was formed in 1605 and Colonel Henry O'Neill was placed at its head. Five other Irish regiments were formed between 1632 and 1646 and were placed under the command of The Earl of Tyrconnell, Owen Roe O'Neill, Thomas Preston, Patrick FitzGerald and John Murphy. Later they were joined by Irishmen who had served in the army of Henri de Bourbon and Charles IV. The difficulties that plagued them at home were carried to the continent when O'Donnells refused to serve under O'Neills and tension existed between the Old English and the Old Irish. This was especially evident in tensions between O'Neill and Preston.
After the Cromwellian conquest of Ireland there was a fresh exodus of men which suited the English as it ensured that men of fighting age would be engaged in wars on the continent. In one incident in 1653 during the Siege of Girona some of the Irish defenders deserted and joined the French under de Bellefonds. With the restoration of Charles II in 1660 most of the remaining Irish chose to return to Ireland. Two regiments remained under the command of the O'Neills and.
With the War of Succession in 1701 Irish regiments were reformed mostly via France. Two dragoon regiments were formed and named after their founders, O'Mahony and Crofton. Four infantry regiments were formed between 1702 and 1718 while a fifth transferred from French service in 1715. They were named:
