British settlers in the Argentine pampas started practising it during their free time. Among them, David Shennan is credited with having organised the first formal polo game of the country in 1875, at Estancia El Negrete, located in the province of Buenos Aires.
The sport spread fast between the skilful gauchos and several clubs opened in the following years in the towns of Venado Tuerto, Cañada de Gómez, Quilmes, Flores and later (1888) Hurlingham. In 1892 The River Plate Polo Association was founded and constituted the basis for the current Asociación Argentina de Polo. In the Olympic Games held in Paris in 1924 a team composed by Juan Miles, Enrique Padilla, Juan Nelson, Arturo Kenny, G. Brooke Naylor and A. Peña obtained the first gold medal for the country's olympic history; this also occurred in Berlín 1936 with players Manuel Andrada, Andrés Gazzotti, Roberto Cavanagh, Luis Duggan, Juan Nelson, Diego Cavanagh and Enrique Alberdi.
From then on, the game spread powerfully across the country and Argentina is credited globally as the mecca of polo, mainly because Argentina is notably the country with the largest number ever of 10 handicap players in the world.
Five great teams were able to ensemble together four 10 handicap players in order to make a 40 handicap team: Coronel Suárez, 1975, 1977–1979 (Alberto Heguy, Juan Carlos Harriott, Alfredo Harriot and Horacio Heguy); La Espadaña, 1989–1990 (Carlos Gracida, Gonzalo Pieres, Alfonso Pieres y Ernesto Trotz Jr.); Indios Chapaleufú, 1992–1993 (Bautista Heguy, Gonzalo Heguy, Horacio Heguy Jr. and Marcos Heguy); La Dolfina, 2009–2010 (Adolfo Cambiaso Jr., Lucas Monteverde, Mariano Aguerre y Bartolomé Castagnola); Ellerstina, 2009 (Facundo Pieres, Gonzalo Pieres Jr., Pablo Mac Donough and Juan Martín Nero).
Argentina was host of the ninth edition of the World Polo Championship (for teams of up to 14 goals) at the Estancia Grande Polo Club, in the province of San Luis in October 2011.
The three major polo tournaments in Argentina, known as "Triple Corona" ("Triple Crown"), are Hurlingham Polo Open, Tortugas Polo Open, Palermo Polo Open. Polo season usually last from October to December.
Polo then found popularity throughout the rest of the Americas like Brazil, Chile, Mexico, and the United States of America.
