The Battle Over Birthright Citizenship: History, Legal Precedent, and the 14th Amendment

As the political season intensifies, questions surrounding birthright citizenship have once again taken center stage in American public discourse. Former President Donald Trump, the Republican presidential nominee, has proposed signing an executive order on his very first day in office to revoke birthright citizenship for the future children of undocumented immigrants. However, legal advisors and hardline allies are pushing the envelope even further, seeking to strip birthright citizenship from all children born to non-citizens. Critics point out that such sweeping measures would fundamentally undermine the foundational premise of the 14th Amendment of the U.S. Constitution, which explicitly guarantees citizenship to "all persons born or naturalized in the United States."

This ongoing debate strikes at the heart of the American identity and what it means to be a citizen. Proposals aimed at restricting birthright citizenship fly in the face of more than 125 years of established legal practice, a tradition rooted in judicial interpretations of the 14th Amendment and, more broadly, the very founding principles of the nation. Despite this legal foundation, recent years have seen the rise of a concerted public policy apparatus dedicated to redefining and rolling back birthright citizenship, largely catalyzed by a surge in both legal and undocumented immigration. Proponents of the most extreme views argue that neither the children of undocumented immigrants nor the children of legal immigrants who have not yet naturalized possess a rightful claim to birthright citizenship. Furthermore, advocates of this restrictive perspective insist that overturning birthright citizenship for these marginalized groups can be achieved through mere executive action or simple legislation, bypassing the rigorous constitutional amendment process entirely. As this issue gains increasing prominence in the national conversation, examining the historical context and legal mechanics of the 14th Amendment provides crucial clarity.

The 14th Amendment states clearly: "All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside."

Why Was the 14th Amendment Necessary in the First Place?

Although birthright citizenship had been practiced in the United States since its founding, it originally excluded specific classes of people, most notably Native Americans and enslaved Africans. The situation escalated dramatically with the U.S. Supreme Court’s infamous 1857 Dred Scott decision, which ruled that all people of African descent—whether enslaved or free, and regardless of whether they lived in slave states, free states, or federal territories—were excluded from citizenship. This judicial ruling helped ignite the American Civil War, the deadliest conflict in the nation’s history. In the war’s aftermath, Congress was intensely determined to ensure that newly emancipated Black Americans could not be stripped of their fundamental rights by former Confederate states. Lawmakers sought to guarantee citizenship for African Americans regardless of their state of residence, thereby explicitly overturning the Supreme Court’s Dred Scott ruling.

When Congress approved the 14th Amendment, did members intend for its protections to extend only to former slaves and other individuals of African descent?

Congress and the ratifying states adopted the Reconstruction Amendments—the 13th, 14th, and 15th Amendments—within a five-year span following the conclusion of the Civil War to rectify specific injustices suffered by Black Americans. The 13th Amendment abolished slavery nationwide, and the 15th Amendment prohibited federal and state governments from denying citizens the right to vote "on account of race, color, or previous condition of servitude." Yet the 14th Amendment, the most complex and far-reaching of the Reconstruction amendments, makes no explicit reference to either slavery or race. Instead, it establishes broad language stating that all persons born or naturalized in the United States, and subject to its jurisdiction, are citizens. The Senate debated the meaning of "citizenship" within the amendment at great length. The historical record of those debates and their final resolution make it unmistakably clear that the language was intentionally crafted to confer birthright citizenship upon all individuals born within the United States, subject only to minor exceptions.

Opponents of birthright citizenship for the children of non-naturalized immigrants often focus on the phrase "and subject to the jurisdiction thereof" as a disqualifier for children born to parents who lacked legal status at the time of birth. What about parents who are legally present in the United States? Would the phrase exclude their children as well?

While many everyday citizens harbor reservations about automatic citizenship for children born on U.S. soil to undocumented immigrants, the organized political movement to restrict birthright citizenship goes significantly further. Leading restrictionist advocates argue that only the children of native-born Americans and naturalized immigrants should be eligible for citizenship at birth. Under their interpretation, children born to lawful permanent residents, temporary foreign workers, international students, and other individuals who have not yet completed the full naturalization process would be excluded. Their central legal theory contends that non-naturalized residents are not subject to the "full political jurisdiction" of the United States, but rather merely to a "partial territorial jurisdiction."

What did the framers of the amendment mean by "subject to the jurisdiction thereof," and whom did they intend to exclude?

The congressional debates surrounding the amendment were extensive and occasionally contentious, focusing on three specific categories of individuals: the children of foreign diplomats born in the United States, Native Americans, and certain immigrant groups. Senator Jacob Howard of Michigan, a primary sponsor of the amendment whose proposed language became the final text of Section 1’s opening sentence, directly addressed the intended exclusions. When asked what exceptions the phrase "subject to the jurisdiction" entailed, Howard explained that the amendment simply codified existing national law, ensuring that every person born within the limits of the United States and subject to its jurisdiction is a citizen by birth and national law. He noted that this would naturally exclude children born to foreign diplomats or ministers accredited to the U.S. government, but would encompass virtually every other class of person, thereby resolving lingering doubts regarding national citizenship.

Why did the amendment exclude Native Americans?

Native Americans did not secure full U.S. citizenship, including voting rights, until the passage of the Indian Citizenship Act in 1924. The historical relationship between the federal government and Native American tribes was defined by profound conflict, discrimination, and active warfare. At the time the 14th Amendment was adopted, most Native Americans were legally regarded as citizens of sovereign nations with which the United States maintained treaty relationships or engaged in outright hostilities. Throughout the 19th century, multiple wars erupted between the federal government and various tribes. By 1866, the U.S. government signed treaties with several tribes in the Oklahoma territories, requiring them to abolish slavery and extend rights to formerly enslaved Black individuals and their descendants as a condition of peace.

What about the children of foreign-born immigrants living in the United States at the time of the amendment’s passage? Were they considered citizens by birth?

During the drafting process, several senators proposed excluding other groups as well, including the Chinese, "gypsies," and other populations described in overtly xenophobic terms. Senator Edgar Cowan of Pennsylvania expressed anxiety that California might be "invaded by a flood of Australians or people from Borneo, man-eaters, or cannibals," questioning whether states were powerless to protect themselves from rapid demographic shifts brought by foreign populations with different religions, customs, and traditions. Conversely, Senator John Conness of California, an Irish immigrant who represented his adopted state, fiercely opposed Cowan’s rhetoric. In a detailed response, Conness defended the inclusion of children born to Chinese parents in California, arguing that denying civil rights and equal protection to children born on American soil simply because of their lineage ran counter to any genuine sense of humanity.

Did the drafters foresee a large population of children born to non-citizen parents, or did they view it as a minor demographic factor?

The 19th century experienced large-scale immigration to the United States, sparking a fierce political backlash. A powerful nativist movement emerged in the 1850s, embodied by the Know Nothing Party—later known as the American Party—which achieved success in local, state, and national elections and ran former President Millard Fillmore as its presidential candidate in 1856. The Know Nothings were virulently anti-immigrant and specifically hostile toward Catholic immigrants arriving in vast numbers from Ireland. The 1860 census recorded that more than 13 percent of the U.S. population was foreign-born, a figure comparable to modern rates. Senators debating the 14th Amendment were acutely aware of these mid-century demographic shifts. Notably, none of them suggested that eligibility for birthright citizenship should be restricted solely to children whose parents had already naturalized—a process that was cumbersome, unstandardized, and rarely utilized by many immigrants, particularly women, during that era.

What about children born to parents living illegally in the United States? At the time the 14th Amendment was adopted, were all immigrants whose children received automatic citizenship legal residents?

The modern regulatory category of "illegal immigrants" did not exist in the legal framework familiar to the framers of the 14th Amendment. At that time, the United States maintained essentially open borders, with minimal restrictions on immigration, barring criminals, prostitutes, and individuals suffering from certain physical or mental illnesses. Even those limited restrictions were enforced unevenly until the late 19th century. Following the Civil War, some individual states attempted to enact localized immigration controls, but these state laws were struck down by the Supreme Court in 1875 in the case Chy Lung v. Freeman, where the Court ruled that the regulation of foreign immigration falls exclusively under federal congressional authority.

Despite this ruling, anti-immigrant sentiment persisted, leading Congress to pass the Chinese Exclusion Act of 1882, the first major federal law explicitly banning immigration from a specific nationality. This was quickly followed by the Immigration Act of 1882, which introduced a head tax on immigrants, established a federal immigration bureaucracy, and authorized the exclusion of specific classes of arrivals.

Has the Supreme Court ever resolved how birthright citizenship applies to the children of undocumented or non-citizen immigrants?

The U.S. Supreme Court directly addressed the application of birthright citizenship to the children of foreign nationals in the landmark 1898 case United States v. Wong Kim Ark. Wong was born in San Francisco in 1873 to parents who had emigrated from China. Amid mounting anti-Chinese sentiment and the enforcement of the Chinese Exclusion Act, Wong’s parents returned to China in 1890, accompanied briefly by their teenage son before he returned to California. In 1895, following a visit to his parents in China, Wong was denied re-entry at the port of San Francisco, prompting a three-year legal battle to establish his constitutional citizenship.

The Supreme Court ruled definitively that, regardless of his parents’ foreign citizenship or subsequent return to China, a child born on U.S. soil while their parents are domiciled in the United States becomes a citizen at birth. Addressing arguments that children of non-naturalized immigrants remain subjects of a foreign power, the majority opinion emphasized that such facts cannot exclude individuals born in the country from the broad, clear mandate of the 14th Amendment.

Has the Supreme Court ever revisited the Wong Kim Ark precedent?

The high court has never overturned or re-evaluated the core legal reasoning established in Wong Kim Ark. Nevertheless, conservative legal scholars and prominent critics of birthright citizenship, such as John Eastman of the Claremont Institute, have periodically urged the judiciary to reconsider the doctrine. In the 2004 case Hamdi v. Rumsfeld, which centered on due process rights and the wartime detention of an American-born individual captured fighting for the Taliban in Afghanistan, Eastman filed an amicus curiae brief arguing that Yaser Esam Hamdi was not a citizen despite being born in Baton Rouge, Louisiana, because his parents were temporary visa holders at the time. However, none of the Supreme Court justices—not even those who voted against granting Hamdi broader procedural rights—questioned his status as a birthright citizen, with Justice Antonin Scalia explicitly describing Hamdi as an American citizen.

Is there any legal avenue for opponents to alter the guarantee of birthright citizenship?

The only mechanisms available to alter birthright citizenship as guaranteed by the Constitution are passing a constitutional amendment or successfully challenging the established judicial interpretation of the 14th Amendment in federal court. While critics have repeatedly introduced federal legislation aimed at stripping birthright citizenship from the children of undocumented immigrants, these proposals have consistently stalled because legal scholars agree they would not survive constitutional review.

Ironically, abolishing birthright citizenship by statute or executive order would immediately expand the undocumented population in the United States, adding millions of unauthorized individuals to government registries overnight. While amending the Constitution requires a two-thirds vote in both houses of Congress and ratification by three-fourths of state legislatures, attempting to dismantle birthright citizenship would fundamentally transform the constitutional landscape of the United States.

Birthright citizenship remains a cornerstone of American exceptionalism, reflecting a historical tradition of national integration and civic inclusion. While the nation has confronted profound historical failures—ranging from the horrors of slavery to the systemic discrimination of the Jim Crow era—the arc of American jurisprudence has consistently trended toward expanding, rather than restricting, fundamental rights. Through the 13th, 14th, 15th, and 19th Amendments, successive generations worked to extend liberty, citizenship, and the franchise to marginalized populations. For nearly two and a half centuries, the United States has continually strived to realize the foundational ideals articulated in the Declaration of Independence.
