This work--the first of its kind in more than sixty years--covers polo in Argentina, from its beginnings in the 1870s to the summer of 2013. The history of the early pioneers is constructed with data not previously published, gathered from contemporary sources. International competitions are covered and include the Olympic Games, the Cup of the Americas and the World Championships. Particular attention is given to the major clubs, the Argentine and Hurlingham Open Championships, and the National Handicap Tournament. Several of the elite players merit individual or family mini-biographies. Myths in Argentine polo are also debunked, based upon careful analysis of contemporary sources. Travels abroad by Argentine teams are fully described as are the foreign teams that competed in Argentina. The work is enhanced by the author's personal observation of significant events and friendship with many of the participants.
