In the 1990s the UKA experienced a resurgence of activity of members who returned to teachings of William Joseph Simmons, who had founded and led the second Ku Klux Klan from 1915 to 1922. Simmons taught a kind of fraternal organization that is practiced by the UKA in the 21st century. It has several Klaverns active in twenty nine states, according to the Southern Poverty Law Center. The UKA's membership is not precisely known. Its leadership is believed to be weak and its activities are limited to ceremonial practices with no clear political agenda.
