Subsequent amendments (11–27)
Amendments to the Constitution subsequent to the Bill of Rights cover many subjects. The majority of the seventeen later amendments stem from continued efforts to expand individual civil or political liberties, while a few are concerned with modifying the basic governmental structure drafted in Philadelphia in 1787.
