How did the U.S. Bill of Rights change the focus of constitutional government?

The U.S. Bill of Rights shifted the focus of constitutional government by establishing explicit, legally binding limitations on the power of the federal government to infringe upon individual liberties. While the original Constitution primarily outlined the structure and powers of the government, it contained limited protections for citizens.12

The addition of the first 10 amendments in 1791 was driven by popular dissatisfaction and the influence of Anti-Federalists, who feared that a strong central government could threaten personal freedom. By codifying rights such as freedom of speech, freedom of religion, and due process, the Bill of Rights transformed the Constitution into a document that not only organized the state but also served as a primary safeguard for the individual against state authority.2341

Initially, these protections applied only to the federal government. However, following the American Civil War, the Fourteenth Amendment allowed the U.S. Supreme Court to gradually incorporate these guarantees, extending their reach to protect citizens from state-level infringements as well.12
