The Mangalarga Marchador takes its name from two sources: "Mangalarga" from the farm in Rio de Janeiro where the breed gained fame, and "Marchador" from the distinctive marching gait (marcha) that defines the breed. The word "marchador" means "one who marches" in Portuguese, directly referencing the smooth, rhythmic gaits unique to this breed.
The Associação Brasileira dos Criadores do Cavalo Mangalarga Marchador (ABCCMM), founded in 1948 in Caxambu, Minas Gerais, maintains the official studbook and oversees breeding standards. The association requires that horses pass rigorous evaluation of conformation, gait, and temperament before receiving permanent registration and breeding approval. Approved horses receive the distinctive horseshoe brand with an "M" in the center, a trademark protected in both Brazil and the United States.
In North America, the U.S. Mangalarga Marchador Association (USMMA) functions as a nucleo (affiliate) of the ABCCMM, maintaining equivalent standards and registration protocols. The breed exists internationally, with significant populations in Europe, particularly Germany, in addition to growing numbers in the United States and other countries.
Naming conventions for Mangalarga Marchadors follow traditions unique to the breed. Each horse receives a compound name including both an individual identifier and a surname indicating the breeding farm of origin. Historic farm names like Abaiba, Favacho, Passa Tempo, Tabatinga, and Traituba appear in pedigrees worldwide, connecting modern horses to foundation bloodlines. This naming system tells each horse's heritage and maintains connection to the breed's Brazilian roots.
