Established in 1926 in Davenport, Iowa, USA by Dr. B. J. Palmer, the International Chiropractors Association (ICA) is the world's oldest international chiropractic professional organization representing practitioners, students, chiropractic assistants, educators and lay persons world-wide. The ICA is dedicated to the growth and development of the chiropractic profession based on Dr. Palmer’s fundamental belief in the principle and philosophy of chiropractic as a unique, separate, distinct and drugless health care profession.
ICA's distinguishing feature today is the same as it was in 1926 – advocating for chiropractic. For nearly 90 years, the ICA has advocated and, when necessary, litigated to support the chiropractic profession and quality patient care. With the support of ICA’s dedicated members and leaders globally, chiropractic is a formally recognized and respected health care choice.
As noted chiropractic historian, Russell Gibbons wrote in 1996:
"The story of ICA's maintenance of principle and scope of practice, its growing and systemic efforts through the legislative process and its influence upon opinion makers is a remarkable account. For with minimum resources, ICA created an effective lobby for chiropractic and pioneered the concept of public relations, which eventually was to change the perception of millions of Americans toward chiropractic as a legitimate and respectable health care alternative."
