Which Constitutional amendment was ratified to ensure individuals cannot be deprived of life, liberty, or property without due process?

The amendment designed to protect individuals from being deprived of life, liberty, or property without due process is the Fifth Amendment. This amendment, ratified in 1791, establishes that no person shall be "deprived of life, liberty, or property, without due process of law," thereby ensuring legal safeguards for individuals in legal proceedings.

While the Fourteenth Amendment also includes a due process clause and extends this protection to actions taken by state governments, it was specifically the Fifth Amendment that originally provided this essential protection against federal government actions. The Sixth Amendment focuses on the rights of individuals in criminal prosecutions, such as the right to a fair trial and legal representation. The First Amendment addresses freedoms concerning religion, expression, assembly, and the right to petition but does not discuss due process. Thus, the Fifth Amendment is the correct answer in the context of protecting due process rights at the federal level.
