"Whosoever will may come" was the generous welcome which America extended to all the world for over a century. Many alarms, indeed, there were and several well-defined movements to save America from the foreigner. The first of these attempts resulted in the ill-fated Alien and Sedition laws of 1798, which extended to fourteen years the period of probation before a foreigner could be naturalized and which attempted to safeguard the Government against defamatory attacks. The Jeffersonians, who came into power in 1801 largely upon the issue raised by this attempt to curtail free speech, made short shrift of this unpopular law and restored the term of residence to five years. The second anti-foreign movement found expression in the Know-Nothing party, which rose in the decade preceding the Civil War. The third movement brought about a secret order called the American Protective Association, popularly known as the A.P.A., which, like the Know-Nothing hysteria, was aimed primarily at the Catholic Church. Its platform stated that "the conditions growing out of our immigration laws are such as to weaken our democratic institutions," and that "the immigrant vote, under the direction of certain ecclesiastical institutions," controlled politics. In 1896 the organization claimed two and a half million adherents, and the air was vibrant with ominous rumors of impending events. But nothing happened. The A.P.A. disappeared suddenly and left no trace. For over a century it was almost universally believed that the prosperity of the country depended largely upon a copious influx of population. This sentiment found expression in President Lincoln's message to Congress on December 8, 1863, in which he called immigration a "source of national wealth and strength" and urged Congress to establish "a system for the encouragement of immigration." In conformity with this suggestion, Congress passed a law designed to aid the importation of labor under contract. But the measure was soon repealed, so that it remains the only instance in American history in which the Federal Government attempted the direct encouragement of general immigration.[50]
