Final answer:
Ida B. Wells' pamphlet "The Reason Why" at the World's Fair highlighted the justifications for lynching and the exclusion of African American accomplishments as the "twin infamies." As a civil rights leader and journalist, she emphasized lynching as a tool of oppression rather than a response to crime.
Step-by-step explanation:
In her pamphlet "The Reason Why" at the World's Fair, Ida B. Wells argued that the "twin infamies" were the justifications used for the lynching of African Americans and the exclusion of African American achievements from the exposition's representation of American progress. Wells' ardent activism was grounded in her deep understanding of the systematic oppression faced by African Americans, cultivated through her experiences as a journalist, a civil rights leader, and a suffragist. She documented various accounts of lynching in her pamphlet, Southern Horrors: Lynch Law in All Its Phases and played a significant role in raising awareness about racial violence, specifically the false accusations often leveled against African American men as pretexts for lynching.
Ida B. Wells boldly challenged the societal norms and legal structures that endorsed racial discrimination and violence. Her perseverance in uncovering the truth about lynchings and challenging segregation, often at great personal risk, established her as a foundational figure in the civil rights movement and a defender of justice and equality.
