Although immigrants have come by millions into the United States, and have been the main contributing cause of its wonderful national expansion, yet opposition to their coming has manifested itself strongly at different times. In the colonial period the people objected, and rightly, to the maternal solicitude which England evidenced by making the colonies the dumping ground for criminals and undesirables. However, these objections were disregarded and convicts and criminals continued to come while the colonies remained under British rule. After the national era, immigration was practically unrestricted down to 1875. At different periods there were manifestations of a strong desire to restrict immigration, but Congress never responded with exclusion laws. The alien and sedition laws of 1798 had for their object the removal of foreigners already residents in the United States. The naturalization laws passed that same year, lengthening the time of residence necessary for citizenship to fourteen years, were another severe measure against resident aliens. The native American and the Know-nothing uprisings were still other indications of that same spirit of antagonism to the alien based on religious grounds. This religious antagonism in many of the States took the form of opposition to immigration itself and a demand for restrictions. But this all proved futile, for the National Government recognized the necessity of settling the limitless West. Then, too, another subject loomed large and threatening at this time, and engrossed the attention of the people away from the dire evils which the Irish and the Catholics would precipitate upon “our free and happy people”. This was the State Rights and Slavery question; and soon the country forgot immigration in the throes of the Civil War.
