The Oath of Allegiance for prospective citizens originated with the Naturalization Act of 1790, which required applicants to take an oath or affirmation "to support the constitution of the United States", but did not provide a text. The Naturalization Act of 1795 added renunciation of the new citizen's former sovereign to the oath. The Naturalization Act of 1906 added the section of the oath requiring new citizens to defend the Constitution and laws of the United States of America against all enemies, foreign and domestic; and bear true faith and allegiance to the same.
