Answer:
As an effect of her writings about attacks on African Americans, Ida B. Wells had to leave Memphis, as many white people threatened her.
Step-by-step explanation:
Ida B. Wells was an African-American woman co-founder of the National Association for the Advancement of Colored People and dedicated to the defense of civil rights and the rights of women in the United States.
In 1889 she began to co-own and write a newspaper against segregation that was published in Memphis, whose name was Free Speech. In 1892 she was forced to leave the city because of the publication of an article written by her denouncing the lynching of three friends who owned a grocery store accused of taking away customers from their white competitors. Many African-Americans decided to leave the city while others organized boycotts for businesses whose owners were white, as a result Wells moved her residence to Chicago.
In 1892 she published a famous pamphlet entitled: "Southern Horrors: Lynch Law in All Its Phases", which together with another entitled "A Red Record" were the beginning of her documented research and campaign against lynchings. Having contrasted different cases of lynching due to accusations against black men of raping white women, she concluded that in the southern United States the excuse of alleged abuse was used to hide the real motive of lynching African American men: the economic progress of black people, which not only threatened their money but also the idea of the innate inferiority of the black man.
