The club was founded in 1873 by Mr. Horace Rochford, (Mr Horace was 60 when he took up polo but was well known in hunting circles prior to this) on the "Nine Acres" in the Phoenix Park. Three years previously the first authentic game of polo in Ireland was played on Gormanstown Strand, Co. Meath. Co. Meath (captained by Captain Hartopp) beat the 9th Lancers, who were at the time quartered in Ireland.
The Nine Acres is located beside the main road through the Phoenix Park. The polo pavilion is one of the many beautiful buildings in the Park, which is regarded as a prime example of a 17th-century deerpark and attracts crowds of tourists every summer.
Irish players and ponies had a full share in the development of polo in the western world. An article in "The Irish Times" of September 18, 1909, by T.F. Dale, notes that the Irish player John Watson, who captained the famous Freebooters, brought the backhand stoke into general use. Ireland also supplied two of the four players who won the American Newport Cup in 1886, and apparently all the ponies, the article continued.
With the growth of polo in Ireland came a huge increase in the number of spectators in the Phoenix Park every summer. In 1893 the attendance at one tournament was 15,000. In 1909 there were an estimated 30,000 at a tournament.
One of the best-known players in the early years was John Watson, MFH. A contemporary of Horace Rochford, he was described in 1891 as the leading poloist of his day and won countless cups in England, Ireland, India and the USA. While serving in India he drew up a set of rules which form the framework of the existing rules today. On leaving the Army he played regularly in Dublin and won the Cup outright in 1886; he gave the present Freebooters' Cup to replace the original Open Cup, which was inaugurated in 1878 and subscribed to by the members of the club. John Watson never played for his county, preferring to captain the Freebooters, who had no club or ground and consisted of any good players who were invited onto the team.
Mr. Ussher Roberts, well known in connection with the Dublin Horse Show, also did much for the club. It was he who put up the railings on the south side of the ground and organised for the ground to be drained into the lake in the Zoological Gardens.
The Leornard family name has been associated with the All Ireland Polo Club throughout its history. They ensured the club's survival through two world wars and a civil war. John Leonard started to play polo at the County Dublin Polo Club on the Navan Road in 1901.The Leonard's' talent for "making" excellent ponies financed their enjoyment of the sport and raised the standard of play - the cavalry officers in McKee Barracks bought polo ponies from Jack Leonard, and brought their considerable horsemanship into the game. John Leonard was Secretary of the All Ireland Polo Club from 1914 to 1918.
Captain Steeds, who joined the club in 1877, learnt his polo during 12 years of service in the British Army, and had been a member of a team that won the Westchester Cup. His signature is one of two signatures on the original lease of the polo ground from the Board of Works.
Major (later Colonel) Rimington, who was the club's Secretary from 1897 to 99. Major Rimington encouraged many of the younger members of the Ward, Meath and Kildare hunts to take up the game. They, in turn, recruited many of their friends. The original colours of the All Ireland Polo Club were crimson and gold; these were changed to the present green and white by Colonel Rimington.
The old Victorian pavilion was seriously damaged by fire in January 1987. Many old photographs, paintings and sketches, records, etc - were lost. In 1988, when Alex Mackay was president of the club, a hard-working committee reinstated the club to its former glory and the completely renovated clubhouse. The pavilion has been faithfully restored to its original Victorian design, complete with elegant railings and intricate woodwork. The only change has been to build it larger that the original, to accommodate a growth in membership.
Trips abroad have increased too. All Ireland Polo Club teams have visited Argentina, the UK, the USA, Pakistan, Canada and many other countries.
With the input of new players, the club is flourishing today. Today, there is talk to reintroducing polo as an Olympic sport. If polo in Ireland continues to grow at its present rate, we stand a good chance of repeating Ireland's performance in 1936, when General Dawnay, father of Major Hugh Dawnay, competed as part of the British Army team in Berlin, in 1908, when an Irish team won silver medals.
