National Rifle Association of America
The NRA began after the American Civil War.  Leaders of the Union army were upset because the Union recruits could not shoot guns well.  They would fire and miss many times, and this wasted ammunition.  They started the NRA to teach men how to use guns.  For most of the 20th century, the NRA was mostly about teaching people how to use guns.  The NRA cooperated with the government.  For example, the State of New York helped the NRA buy a gun range.
