This six-minute video illustrates the battle between two of the most powerful trends of the 1920s: the increasing political power of urban immigrants, and the increasing influence of the Ku Klux Klan. At the 1924 Democratic Party national convention, these two forces fought to a standstill, leading to the longest convention in the history of American politics. The video is useful to lessons covering the 1924 election, or for lessons focused on the cultural and demographic changes of the 1920s.
