What rights did they guarantee for American citizens?

The Bill of Rights, the first ten amendments to the U.S. Constitution, guarantees essential rights for American citizens, including freedom of speech, religion, and assembly (First Amendment); the right to bear arms (Second Amendment); protection against unreasonable searches and seizures (Fourth Amendment); and the right to a fair trial (Sixth Amendment). These amendments ensure fundamental civil liberties and protections against government overreach, safeguarding individual freedoms and promoting justice. Additionally, they provide rights related to due process and protection from cruel and unusual punishment.
