The Naturalization Act of 1790: How the First Congress Defined American Citizenship

When the United States became an independent nation, one of the first questions its leaders had to answer was deceptively simple:

Who could become an American?

The Constitution had created a new federal government, but it did not provide a detailed national system for turning immigrants into citizens. Article I gave Congress the power to establish a "uniform Rule of Naturalization." Congress exercised that power almost immediately.

On March 26, 1790, President George Washington signed the Naturalization Act of 1790 into law.

It was short. It was direct. And its language provides an important window into how the founding generation thought about citizenship, immigration, and membership in the new republic.

What the Act Actually Said

The central provision declared that:

"any alien, being a free white person"

who had lived within the United States for two years could apply for citizenship, provided that a court found the applicant to be a person of "good character."

That language matters.

Citizenship through naturalization was not presented as something automatically available to every person who entered or resided in the United States. Congress established qualifications for admission into the political community.

The applicant had to meet residency requirements, appear before a court, demonstrate good character, and fall within the racial classification established by Congress.

By modern standards, the racial restriction is unmistakably discriminatory. It would eventually be dismantled through later legislation and constitutional development.

But understanding history requires reading the law as it existed rather than rewriting it according to modern expectations.

The first federal naturalization law restricted eligibility to "free white persons."

The Founders Were Legislating

The timing is particularly significant.

The Naturalization Act was passed by the First United States Congress.

This was not a Congress operating generations after the Constitution was written. Many of the people participating in the new federal government had been directly involved in the Revolution, the Constitutional Convention, or the state ratification debates.

George Washington was president.

John Adams was vice president.

James Madison served in the House of Representatives.

The legislation therefore gives us unusually early evidence of how the founding generation implemented the Constitution's naturalization power when forced to turn constitutional principles into actual law.

That does not mean every provision of the 1790 Act permanently defines American citizenship. Congress itself changed the naturalization laws repeatedly.

It does mean the Act deserves serious attention when discussing the historical development of American citizenship.

Naturalization Is Not Birthright Citizenship

An important distinction is frequently lost in modern discussions.

The Naturalization Act of 1790 primarily concerned naturalization.

Naturalization answers the question:

Under what circumstances can someone who is not already an American citizen become one?

Birthright citizenship asks a different question:

Who becomes a citizen automatically because of the circumstances of his or her birth?

The modern constitutional debate surrounding citizenship by birth is primarily associated with the Fourteenth Amendment, ratified in 1868—nearly eight decades after the Naturalization Act.

The 1790 Act therefore should not be presented as though Congress had enacted the modern Fourteenth Amendment doctrine in 1790.

It had not.

But the Act does contain an important provision concerning children born outside the United States.

"Natural Born Citizens"

The statute provided that:

"the children of citizens of the United States, that may be born beyond sea, or out of the limits of the United States, shall be considered as natural born citizens"

subject to qualifications concerning the citizenship of their fathers.

This provision is historically fascinating because it demonstrates that the First Congress did not view physical birthplace as the only possible connection between citizenship and birth.

A child could be born outside the territorial United States and nevertheless be regarded by federal law as a citizen from birth because of descent from American citizens.

That does not settle every modern argument concerning the constitutional meaning of "natural born Citizen." Scholars and courts have debated the significance of the statute and its terminology.

But it does demonstrate something important:

From the beginning of the Republic, citizenship involved questions of both place and parentage.

Citizenship and National Membership

The Naturalization Act also reveals something broader about the early American understanding of national membership.

The United States was a nation receiving immigrants, but the federal government nevertheless claimed the authority to determine the conditions under which outsiders could formally join the political community.

Residency mattered.

Character mattered.

Parentage could matter.

And, regrettably from a modern perspective, race mattered.

The requirements changed dramatically over the following two centuries, but the underlying governmental function remained: the United States maintained legal rules determining who was a citizen and how citizenship could be acquired.

This history becomes particularly relevant when modern discussions collapse several different concepts into a single word.

Citizenship, nationality, ancestry, ethnicity, birthplace, and nativeness are related concepts, but they are not identical concepts.

A person can become a citizen of a country without having been born there.

A person can be born outside a country while inheriting citizenship from his parents.

A family can live in a country for generations while retaining ancestral origins somewhere else.

And a person's legal citizenship does not, by itself, answer every historical or cultural question about whether that person is "native" to a place.

What Changed After 1790?

The 1790 law did not last long.

Congress replaced it with the Naturalization Act of 1795, increasing the residency requirement and modifying the naturalization process. Additional changes followed in 1798 and 1802.

The racial restrictions survived much longer.

Following the Civil War, Congress expanded naturalization eligibility to persons of African descent. Restrictions affecting Asian immigrants persisted into the twentieth century, and the racial qualifications embedded in American naturalization law were eventually eliminated.

The Fourteenth Amendment introduced another enormous change in 1868:

"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."

From that point forward, American citizenship law had to be understood through both federal statutes and the Constitution itself.

That history is important because there was never one single citizenship rule frozen permanently in 1790.

American citizenship law evolved.

Why the 1790 Act Still Matters

The Naturalization Act of 1790 cannot answer every modern argument about immigration or citizenship.

It should not be asked to.

What it can do is establish a historical starting point.

The first generation governing under the Constitution understood that citizenship required legal definition. Congress exercised its constitutional authority to determine who could enter the American political community through naturalization, while also recognizing citizenship acquired through descent in circumstances involving children born outside the country's borders.

Some of the distinctions Congress made were later rejected.

Others evolved.

Still others remain recognizable in American immigration and citizenship law today.

But the document leaves us with a question that remains surprisingly relevant more than two centuries later:

What makes someone American?

Is it birthplace?

Citizenship?

Parentage?

Ancestry?

Culture?

Generations of attachment to the land?

Or some combination of them?

Those questions cannot be answered merely by quoting a single law from 1790.

But if we are going to debate what it means to be native to America, the laws written by the people who established the American republic are an important place to begin.
