What does the 15th Amendment guarantee?

The 15th Amendment, ratified in 1870, explicitly guarantees that the right to vote cannot be denied or abridged on account of race, color, or previous condition of servitude. This was a significant milestone in the struggle for civil rights in the United States, aiming to ensure that African American men, particularly in the post-Civil War era, could participate in the electoral process. The amendment was a crucial step towards achieving political equality, reflecting the intent to build a more inclusive democracy.

The other options focus on different rights and protections that are covered under other amendments or laws. For instance, the right to vote for women is secured by the 19th Amendment, while rights for the accused are addressed in the 6th Amendment. Similarly, protections against unreasonable searches and seizures are part of the 4th Amendment. Thus, while they are important aspects of citizens' rights, they do not pertain specifically to the guarantee provided by the 15th Amendment.
