The basis of the organization came in 1841.
The organization transmuted further from other war fighting groups like The General Society of the War of 1812, The Grand Army of the Republic and The Order of Indian Wars.
All these had the same general philosophy, so had a common ground.
By 1886, it was realized that these organizations would naturally become extinct due to deaths of the veterans if something wasn’t done to give them new life.

These fighting group organizations founded the Army and Navy Union of the United States of America that was open to all who had served honorably or are serving in the United States Armed Forces.
