Why did it take nearly a century for the full effect of the Fifteenth Amendment to be felt?

I can't find the passage in my textbook and I'm confused. I know what the fifteenth amendment means but not this.

Read the first paragraph carefully:

Sorry I forget to say it is for art the question is.

What would be the most common cause of deterioration to a fifteenth century book?

The Fifteenth Amendment, passed in 1870, granted African American men the right to vote. However, its full effect was not felt until nearly a century later due to several reasons.

1. Resistance and Intimidation: Despite the amendment, many Southern states implemented discriminatory practices such as literacy tests, poll taxes, and intimidation tactics to prevent African Americans from voting. These efforts, collectively known as Jim Crow laws, aimed to suppress the political power of African Americans.

2. Supreme Court Decisions: In the late 19th and early 20th centuries, the U.S. Supreme Court handed down decisions that weakened the enforcement of the Fifteenth Amendment. For example, the 1896 Plessy v. Ferguson case upheld racial segregation (known as the "separate but equal" doctrine), which indirectly hindered African Americans' voting rights.

3. Lack of Federal Enforcement: The federal government initially did not take strong measures to enforce the Fifteenth Amendment. It was not until the Civil Rights Movement of the 1950s and 1960s that significant federal action was taken to protect voting rights, including the passage of the Civil Rights Act of 1964 and the Voting Rights Act of 1965.

4. Voting Rights Movement: African Americans and civil rights activists fought tirelessly for equal voting rights during the mid-20th century. Protests, marches, and grassroots organizing efforts brought attention to the barriers faced by African Americans, ultimately leading to legislative changes and court decisions that helped dismantle discriminatory voting practices.

In summary, the delayed impact of the Fifteenth Amendment was primarily due to the resistance, intimidation, discriminatory laws, Supreme Court decisions, lack of federal enforcement, and the slow progress of the broader civil rights movement throughout the century that followed its enactment.
