Constitutional amendments significantly shape citizens' rights by legally altering the frameworks that govern society. For instance, the Bill of Rights enshrines specific protections, like freedom of speech and religion. Amendments can expand rights, such as the 19th Amendment granting women the right to vote, or limit them through provisions that may allow measures like Prohibition. Thus, amendments serve as both a mechanism to protect and sometimes restrict individual rights, directly impacting how citizens experience liberty and participate in democracy.
