Final answer:
Graphs illustrating immigration sources during the Gilded Age reveal demographic changes that fueled societal anxiety, leading to increased lynchings and the resurgence of the KKK. The immigrants, particularly Jewish and Catholic, became targets for discrimination, scapegoating and violence, peaking with the Immigration Act of 1924 and the Tulsa massacre.
Step-by-step explanation:
Information from graphs of sources of immigrants during the Gilded Age and the early 20th century can help us understand the roots of lynching and violence in that era. The waves of immigration led to significant demographic shifts which caused anxiety among many Americans. This anxiety was primarily aimed at new immigrant groups with different customs, languages and religions, particularly those from Southern and Eastern Europe who were predominantly Jewish and Catholic. These immigrant groups were perceived as threats to the job market and the 'traditional' American way of life, leading to scapegoating and discrimination.
As a response to these demographic changes, the Ku Klux Klan experienced a rebirth during the 1920s, expanding its targets to include these new immigrant groups alongside African Americans. The Klan's resurgence paralleled a period of heightened lynching and racial violence, reflecting widespread intolerance that also manifested in restrictive immigration laws like the Immigration Act of 1924. This era witnessed the tragic Greenwood massacre in Tulsa, which exemplified the extreme consequences of racial tensions. Thus, the data on sources of immigration is closely related to the societal conditions that enabled such violence.
