How did the bill of rights change the government?

They put limits on the national government's right to control

Explanation:

They put limits on the national government's right to control specific civil liberties and rights, many of which were already protected by some of the state constitutions. ... Liberties protected included freedom of speech, press, religion, and assembly (First Amendment).

i confess that there are several parts of this constitution which i do not at present approve, but i am not sure i shall never approve them: for having lived long, i have experienced many instances of being obliged by better information or fuller consideration, to change opinions even on important subjects, which i once thought right, but found to be otherwise. it is therefore that the older i grow, the more apt i am to doubt my own judgment, and to pay more respect to the judgment of others.
