David Curtis "Steve" Stephenson was an American Ku Klux Klan leader, convicted rapist and murderer. In 1923 he was appointed Grand Dragon of the Indiana Klan and head of Klan recruiting for seven other states. Later that year, he led those groups to independence from the national KKK organization. Amassing wealth and political power in Indiana politics, he was one of the most prominent national Klan leaders. He had close relationships with numerous Indiana politicians, especially Governor Edward L. Jackson.

The Ku Klux Klan, commonly shortened to the KKK or the Klan, is the name of several historical and current American white supremacist, far-right terrorist organizations and hate groups. According to historian Fergus Bordewich, the Klan was "the first organized terror movement in American history." Their primary targets, at various times and places, have been African Americans, Jews, and Catholics.
