Founded in 1919, The American Legion Auxiliary has nearly 1 million members from all walks of life. The Auxiliary administers hundreds of volunteer programs, gives tens of thousands of hours to its communities and to veterans, and raises millions of dollars to support its own programs, as well as other worthwhile charities familiar to Americans. It is all accomplished with volunteers.

While originally organized to assist The American Legion, the Auxiliary has achieved its own unique identity while working side-by-side with the veterans who belong to The American Legion. Like the Legion, the Auxiliary’s interests have broadened to encompass the entire community.

The American Legion Auxiliary is made up of the male and female spouses, grandmothers, mothers, sisters, and direct and adopted female descendants of members of The American Legion. Through its nearly 10,500 units located in every state and some foreign countries, the Auxiliary embodies the spirit of America that has prevailed through war and peace. Along with The American Legion, it solidly stands behind America and its ideals

Founded in 1932, the Sons of The American Legion (SAL) exists to honor the service and sacrifice of Legionnaires.

SAL members include males of all ages whose parents or grandparents served in the U.S. military and were eligible for American Legion membership. Members of The American Legion (TAL), American Legion Auxiliary (ALA), and SAL comprise the Legion Family, which has a combined membership of nearly 3 million.

Although SAL has its own membership, the organization is not a separate entity. Rather, the SAL is a program of The American Legion. Many Legionnaires hold dual membership in SAL.

The Sons of The American Legion was created in 1932 as an organization within The American Legion. The SAL is made up of boys and men of all ages whose parents or grandparents served in the United States military and became eligible for membership in The American Legion. Together, members of The American Legion, The American Legion Auxiliary and the Sons of The American Legion make up what is known as the Legion Family. All three organizations place high importance on preserving our American traditions and values, improving the quality of life for our nation's children, caring for veterans and their families, and perhaps most importantly, teaching the fundamentals of good citizenship.

The SAL has study programs recommended for younger members. One such program, called "The Ten Ideals," teaches the elements of patriotism, health, knowledge, training, honor, faith, helpfulness, courtesy, reverence and comradeship. If a member completes the Ten Ideals program, he is eligible to continue with another program called the "Five-Point Program of Service." This program covers patriotism, citizenship, discipline, leadership and legionism.

American Legion Riders chapters are well known for their charitable work, which has raised hundreds of thousands of dollars for local children's hospitals, schools, veterans homes, severely wounded servicemembers and scholarships. Since 2006, Riders nationwide have participated in The American Legion Legacy Run to annually raise money for the Legacy Scholarship Fund, established to provide scholarships to children of U.S. military personnel killed since Sept. 11, 2001. 

In Garden City, Mich., in 1993, Chuck "Tramp" Dare and Bill "Polka" Kaledas, commander of American Legion Post 396, shared an idea to start a motorcycle enthusiasts association within the organization. The two longtime riders wanted an environment where Legion family members could come together to share a common love for motorcycles.

Dare and Kaledas wrote a letter to Michigan Department Adjutant Hubert Hess, sharing their idea. Hess replied that he liked the concept and wanted to pursue it. Later, he gave Kaledas and Dare instructions for managing the program at the post level. He also explained how they could be approved to use the American Legion emblem, and how to gain Membership's support and recognition. At a regular meeting, Post 396 members passed a resolution for a new program to be known as the "American Legion Riders."

Joined by 19 other founding members from their post, Dare and Kaledas were flooded with requests for information about their organization. They agreed to establish a central source for the Riders to ensure that chapters formed not as motorcycle clubs or gangs, but as Legionnaires and Auxiliary and SAL members joining to ride as Legion family.
