Final answer:
The Fourteenth Amendment provided citizenship and the right to due process of law to all males, as well as establishing equal protection under the law.
Step-by-step explanation:
The amendment that granted citizenship and the right to due process of law to all males is the Fourteenth Amendment. Ratified in 1868, the 14th Amendment is one of the three Reconstruction Amendments, which also includes the 13th and 15th Amendments. This amendment established that anyone born or naturalized in the United States are citizens of the United States and of the state wherein they reside. The 14th Amendment also includes a due process clause that prevents the states from depriving any person of life, liberty, or property without due process of law, and ensures all citizens equal protection under both state and federal law, thus overturning the Dred Scott decision.
