American Angus Association
The American Aberdeen-Angus Breeders' Association (name shortened in 1950s to American Angus Association) was founded in Chicago, Illinois, on November 21, 1883, with 60 members. The growth of the Association has paralleled the success of the Angus breed in America.
In the first century of operation, more than 10 million head were recorded. The Association records more cattle each year then any other beef breed association, making it the largest beef breed registry association in the world.
