The Prince of Wales's Leinster Regiment (Royal Canadians) was an infantry regiment of the line in the British Army, formed in 1881 by the amalgamation of the 100th (Prince of Wales's Royal Canadian) Regiment of Foot and the 109th Regiment of Foot (Bombay Infantry). The 100th Foot was first raised in 1763 and the 109th was first raised in 1761.
The Prince of Wales's Leinster Regiment was formed in 1881 was first raised in Canada as the 100th Regiment of Foot (Royal Canadians) (also known as the Royal Canadian Regiment). The Regiment originally maintained a recruiting depot in Canada but eventually they moved to Ireland.
In 1875 the 100th Regiment was officially designated to perpetuate the previous 100th Regiment that had served in Canada in the War of 1812. The Battle Honour, "Niagara," (awarded to the older regiment for service in the capture of Fort Niagara and subsequent service on the Niagara frontier) was adopted. This Battle Honour appears on some of the pieces of silver in the collection.
In 1875, the Regiment was authorized to carry the Battle Honour, “Niagara”, on its Colours. Battle Honours borne on the colours prior to World War I also included "Central India" in the Indian Mutiny; "South Africa 1900–02". The Regiment was involved in the colonial service in Aden, the Mediterranean, and the West Indies in the 19th century.
In the Cardwell Reforms of the British army in the 1881, existing single battalion regiments were amalgamated to form new, two battalion units. The 100th Regiment was combined with the 109th Regiment of Foot, then at Aldershot, to form the Prince of Wales's Leinster Regiment (Royal Canadians) with a Regimental HQ and recruit depot established in Leinster province in Ireland. The 100th became the 1st Bn of the new regiment, but their name 'Royal Canadians' was now used for both battalions. The 109th Foot became the 2nd Battalion.
The 2nd Battalion was in Ireland from 1882 until moving to England in 1888. It moved to Malta in 1894, and joined the Bermuda Garrison the following year. In 1897, it moved to Halifax, and in 1898 to the West Indies.
Second Boer War
From Nova Scotia, the 1st Battalion went to the South African War in 1900. It was the last British Army unit to garrison Canada. It remained in South Africa til 1902, following which it was stationed in Ireland and Britain. In 1911, it moved to India.
The 2nd Battalion went to South Africa in 1902. In 1905, it moved to Mauritius, and in 1907 to India. In 1911, it moved to Cork, in Ireland.
A 3rd Militia Battalion, formed from the former King′s County Militia, was embodied in early 1900 for service in South Africa. They embarked in early March 1900, returning to Ireland after more than two years in late May 1902.
The Leinsters, by then, was one of eight Irish regiments of the British Army. Its depot was at Crinkill, near Birr,  and the regiment served the counties of Longford, Meath, Westmeath, Offaly (King's County) and Laois (Queen's County). Prior to the First World War there were five Battalions, including the original two regular battalions, the 1st and 2nd, and three Militia battalions. The 3rd was The King's County Militia, the 4th was The Queen's County Militia and the 5th was The Royal Meath Militia.
Militarily, the whole of Ireland was administered as a separate command within the United Kingdom, with Command Headquarters at Parkgate (Phoenix Park) Dublin, directly under the War Office in London.
First World War
At the declaration of war in 1914 two additional Service Battalions were formed, the 6th Battalion and the 7th Battalion. The Regiment raised seven battalions for service with the British Army during World War I, which saw action on the Western Front and in the Middle East. In the war the 1st Battalion served with the 27th Division and the 10th (Irish) Division. The 2nd Battalion with the 6th Division, 24th Division, 16th (Irish) Division and the 29th Division. The 6th Battalion served with the 10th (Irish) Division, 14th (Light) Division, 34th Division and 66th Division. The 7th Battalion with the 16th (Irish) Division.
Following establishment of the independent Irish Free State in 1922, The Leinsters and the other five regiments that had their traditional recruiting grounds in the counties of the new state were disbanded. The Regimental Colours of these Irish regiments were laid up, in safety and in perpetuity, in Windsor Castle.
In recognition of their Canadian roots, the officers of the 1st Battalion decided to give their officers' mess silver 'in trust' to the Government of Canada- which in turn passed in on 'in trust' to the Commandant of the Royal Military College of Canada. On disbandment the Regiment's collection of silver was presented to the Government of Canada, “as a token of the regard for the Great Dominion which gave birth to the Battalion to be held in trust until such time as the Battalion is again raised”. The silver, known as “The Leinster Plate”, was deposited for safe keeping at the Royal Military College of Canada in 1923 at the suggestion of then Minister of National Defence, the Hon. Edward Mortimer Macdonald, and of Maj-Gen. J.H. McBrien, the Canadian Chief of Staff. The silver is on display at Royal Military College of Canada in the Senior Staff Mess and Museum (Fort Frederic). The Prince of Wales’s Leinster Regiment (Royal Canadians) plaque is on display in the Senior Staff Mess, Royal Military College of Canada. 
The silver of the 2nd Battalion is held by a museum in London.
The present-day guardian of the regimental history is the The Prince of Wales's Leinster Regiment (Royal Canadians) Association
In 2013 the Regimental Association erected a memorial to commemorate the regiment's strong linkages with the area, particularly to Crinkill Barracks. The barracks had been handed over to the new Irish National Army at the time of Irish independence, but were burnt down in July 1922 in the Irish Civil War that followed. Today only the ruins of the outer wall remain.
With the disbandment of the six southern Irish regiments on 31 July 1922 and the simultaneous outbreak of the Irish Civil War conflict some thousands of their ex-servicemen and officers contributed to expanding the Free State government's newly formed National Army. They brought considerable combat experience with them and by May 1923 comprised 50 per cent of its 53,000 soldiers and 20 per cent of its officers.
