Final answer:
The education of Black students in the early 1900s was affected by the establishment of Jim Crow laws that mandated segregation in public schools. These laws resulted in separate but unequal facilities for Black students.
Step-by-step explanation:
During the early 1900s, one factor that affected the education of Black students was the establishment of Jim Crow laws, which mandated the segregation of public schools and other aspects of life based on race. These laws created separate but unequal facilities for Black students, with inferior resources and funding compared to white schools. The Supreme Court's ruling in Plessy v. Ferguson in 1896 further upheld the principle of separate but equal, legitimizing the unequal treatment of Black students in education.
