The U.S. Constitution's 14th Amendment, ratified in 1868, contains what’s known as the "Citizenship Clause," granting citizenship to "all persons born or naturalized in the United States ... ." A panel of professors looks at the history of the 14th Amendment and its grant of birthright citizenship, and how that has affected different ethnic groups, including Native Americans, and immigrant groups such as Asians & Mexicans. The panelists also talk about state and federal efforts over the years to regulate birthright citizenship and touch on recent proposals to amend the Constitution's "Citizenship Clause." This discussion was part of a conference on birthright citizenship hosted by the University of Maryland’s Center for the History of the New America.
