A more thorough explanation:

Term: Disenfranchise
Definition: To take away someone's right to vote or participate in a certain activity or privilege.
Examples:

• After the Civil War, many Southern states passed laws to disenfranchise Black Americans, making it difficult or impossible for them to vote.
• The new policy will disenfranchise many elderly citizens who do not have access to the internet and cannot complete the online application.

The term disenfranchise means to take away someone's right to vote or participate in a certain activity or privilege. The examples illustrate this definition by showing how certain groups of people, such as Black Americans and elderly citizens, have been disenfranchised in the past and present. In both cases, they are being denied the right to vote or participate in a certain activity due to laws or policies that make it difficult or impossible for them to do so.
