# History
Todays American Chiropractic Association (ACA) is an organizational descendant of one of the first national chiropractic membership societies  the Universal Chiropractors Association (UCA), established at the Palmer School of Chiropractic in 1906.
From the humble beginnings of UCA  an organization designed to thwart political medicines efforts to jail chiropractors  organized chiropractic would progress to offer doctors educational opportunities, malpractice insurance, research funding, and accreditation for chiropractic colleges. These developments were largely the result of various successors to the UCA, especially the National Chiropractic Association (NCA: 1930-1963), which is the immediate predecessor of todays ACA.
In 1963, the National Chiropractic Association reorganized into the American Chiropractic Association (ACA).  Todays ACA provides lobbying, public relations, professional and educational opportunities for doctors of chiropractic, funds research regarding chiropractic and health issues, and offers leadership for the advancement of the profession.
