Final answer:
A republic's constitution explicitly outlines and limits governmental powers, thereby protecting the civil liberties and civil rights of its citizens. The U.S. Constitution and its Bill of Rights are key examples, ensuring freedoms such as speech and religion, while also establishing a government that is by and for the people.
Step-by-step explanation:
A republic's constitution is fundamental in shaping the rights of its citizens by serving as the foundational framework that delineates the powers of the government and the liberties of the people. The Bill of Rights, the first 10 amendments to the U.S. Constitution, is a prime example of how constitutional provisions safeguard civil liberties and civil rights, limiting governmental power and ensuring freedoms such as speech, religion, press, assembly, and the right to a fair trial. Over time, the interpretation of these amendments has expanded to protect more people and activities from governmental interference, though it also enables the government to impose necessary limits for the good of the community.
It is the duty of the government to enforce these rights, as prescribed in the constitution, to balance individual freedoms with community welfare. The republic form of government established under the U.S. Constitution stipulates a government that is representative of the people, where power is either directly or indirectly derived from the citizens. Consequently, the government operates to empower citizens while ensuring that no single entity or group can abuse its power and curtail individual rights.
