Question

Quizplus · Accepted Answer

In Guinn v. United States (1915), the Supreme Court declared the "grandfather clause" unconstitutional in Oklahoma and Maryland. The clause waived literacy and other requirements for voting if a person's ancestors had voted before 1866, effectively disenfranchising Black voters who were not yet citizens at that time. This ruling helped pave the way for greater Black participation in the political process.
