Constitutional amendments significantly shape political systems by altering the fundamental legal framework that governs a nation. They can expand or restrict rights, redefine government structures, and influence the balance of power among branches of government. Amendments often reflect the evolving values and priorities of society, as seen in amendments addressing civil rights or voting access. The process of amending a constitution also serves as a barometer for public consensus and political will, highlighting the mechanisms through which democratic principles are expressed and enacted within a governance model.
