The second Ku Klux Klan

The second klan was from 1915–1944

In 1915 the film The Birth of a Nation was released, mythologizing and glorifying the first Klan and its endeavors. The second Ku Klux Klan was founded in 1915 by William Joseph Simmons at Stone Mountain, near Atlanta, with fifteen "charter members". Its growth was based on a new anti-immigrant, anti-Catholic, Prohibitionist and anti-Semitic agenda, which reflected contemporary social tensions, particularly recent immigration. The new organization and chapters adopted regalia featured in The Birth of a Nation; membership was kept secret by wearing masks in public.

The first and third Klans were primarily Southeastern groups aimed against Black people. The second Klan, in contrast, broadened the scope of the organization to appeal to people in the Midwestern and Western states who considered Catholics, Jews, and foreign-born minorities to be anti-American.
