Ava DuVernay’s ‘14th’ examines the amendment’s role in US rights

The 14th Amendment made people born or naturalized in the United States citizens and established equal protection under the law.

Ava DuVernay’s documentary looks at how it shaped rights and democracy after the Civil War.

It argues that the amendment is under threat, including from Donald Trump’s attempt to end birthright citizenship.

The amendment matters because it has been used to support equality movements.
