Aztec Club of 1847

The Aztec Club of 1847 is a military society founded in 1847 by United States Army officers of the Mexican–American War. It is a hereditary organization, including members who can trace a direct ancestral connection to those initially eligible.

Similar to the earlier Society of the Cincinnati, which arose out of the officer class of the American Revolutionary War, the Aztec Club was a precursor of veterans' organizations like the Grand Army of the Republic, the Military Order of the Loyal Legion of the United States and the United Confederate Veterans which veteran officers formed after the American Civil War.
