Final answer:
African Americans were denied their founding ideals during the Jim Crow Era through segregation and discrimination, including Jim Crow laws and restrictive voting practices. This hindered their ability to access equal rights, opportunities, and resources.
Step-by-step explanation:
African Americans were denied their founding ideals during the Jim Crow Era through various methods of segregation and discrimination. Jim Crow laws enforced racial segregation in schools, public buildings, transportation, and other public places. African Americans were subjected to inferior facilities and were denied equal rights and opportunities.
These discriminatory laws were upheld by the United States Supreme Court in the case of Plessy v. Ferguson, which established the principle of separate but equal. African Americans also faced disenfranchisement through restrictive voting practices, such as literacy tests, poll taxes, and white-only primaries.
The denial of African Americans' founding ideals during the Jim Crow Era hindered their ability to reach their potential, limiting access to education, jobs, and housing opportunities.
