A Brief History of the NRA
Dismayed by the lack of marksmanship shown by their troops, Union veterans Col. William C. Church and Gen. George Wingate formed the National Rifle Association in 1871. The primary goal of the association would be to "promote and encourage rifle shooting on a scientific basis.’’ [...]
The NRA's interest in promoting the shooting sports among America's youth began in 1903 when NRA Secretary Albert S. Jones urged the establishment of rifle clubs at all major colleges, universities and military academies. By 1906, NRA's youth program was in full swing with more than 200 boys competing in matches at Sea Girt that summer. Today, youth programs are still a cornerstone of the NRA, with more than one million youth participating in NRA shooting sports events. The National Matches are one of the biggest sporting events held in the country today.
In 1975, recognizing the critical need for political defense of the Second Amendment, NRA formed the Institute for Legislative Action, or ILA.
Meanwhile, the NRA continued its commitment to training, education and marksmanship. During World War II, the association offered its ranges to the government, developed training materials, encouraged members to serve as plant and home guard members, and developed training materials for industrial security. NRA members even reloaded ammunition for those guarding war plants. After the war, the NRA concentrated its efforts on another much-needed arena for education and training: the hunting community. In civilian training, the NRA continues to be the leader in firearms education. Over 125,000 certified instructors now train about 1,000,000 gun owners a year. Courses are available in basic rifle, pistol, shotgun, muzzleloading firearms, personal protection, even ammunition reloading.
Additionally, nearly 7,000 certified coaches are specially trained to work with young competitive shooters. Since the establishment of the lifesaving Eddie Eagle GunSafe® Program in 1988, more than 28 million pre-kindergarten to fourth grade children have learned that if they see a firearm in an unsupervised situation, they should "STOP. DON'T TOUCH. RUN AWAY. TELL A GROWNUP."
In 1990, NRA made a dramatic move to ensure that the financial support for firearms-related activities would be available now and for future generations. Establishing the NRA Foundation, a 501 (c) (3) tax-exempt organization, provided a means to raise millions of dollars to fund gun safety and educational projects of benefit to the general public.
While widely recognized today as a major political force and as America's foremost defender of Second Amendment rights, the NRA has, since its inception, been the premier firearms education organization in the world.
