Those evil spirits, however, which most effectively coöperated to make the last state worse than the first came as the result of the extraordinarily stupid and blundering measures which the Federalists adopted to curb the activities of resident aliens and the abuse of free speech. Beginning with the Naturalization Act of June 18, 1798, there followed in quick succession three other repressive measures, the Act Concerning Aliens of June 25, the Act Respecting Alien Enemies of July 6, and the Act for the Punishment of Certain Crimes against the United States (the Sedition Act) of July 14.[286] The purpose of these famous acts has already been indicated; the impulse out of which they grew is not so easily determined. Was it that the heads of the national government really anticipated danger on account of the presence of a multitude of foreigners and the unlicensed freedom of action and public utterance which thus far had been allowed?[287] Was it that the memory of more than four years of biting satire and vicious calumny which the opposition had visited upon the heads of Federalist leaders had filled the latter with longings for revenge? Or was it that, conscious of their undisputed control of national affairs and carried away by the sense of their power, the Federalist leaders proposed to show how strong and effective a centralized government could become? No single alternative, doubtless, suggests the full truth. No matter; the effect which these measures produced is, with us, the main point, and to that we turn.
