In the 1990s the UKA experienced a resurgence in the activity of its members who returned to the teachings of the Imperial Wizard, Col. William Joseph Simmons, who founded and led the second Ku Klux Klan from 1915 to 1939. Under Simmons' leadership, the second Klan operated as a fraternal organization, a style that is still practiced by the UKA in the 21st century. It has several active Klaverns 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.
