28 late 18th and early 19th century did not criminalize pre-quickening abortions does not mean that anyone thought the States lacked the authority to do so. When legislatures began to exercise that authority as the century wore on, no one, as far as we are aware, argued that the laws they enacted violated a fundamental right. That is not surprising since common-law authorities had repeatedly condemned abortion and described it as an “unlawful” act without regard to whether it occurred before or after quickening. See supra, at 16–21.

Another amicus brief relied upon by respondents (see Brief for Respondents 21) tries to dismiss the significance of the state criminal statutes that were in effect when the Fourteenth Amendment was adopted by suggesting that they were enacted for illegitimate reasons. According to this account, which is based almost entirely on statements made by one prominent proponent of the statutes, important motives for the laws were the fear that Catholic immigrants were having more babies than Protestants and that the availability of abortion was leading White Protestant women to “shir[k their] maternal duties.” Brief for American Historical Association et al. as Amici Curiae 20.

Resort to this argument is a testament to the lack of any real historical support for the right that Roe and Casey recognized. This Court has long disfavored arguments based on alleged legislative motives. See, e.g., Erie v. Pap’s A. M., 529 U. S. 277, 292 (2000) (plurality opinion); Turner Broadcasting System, Inc. v.

The Court has recognized that inquiries into legislative motives “are a hazardous matter.” O’Brien, 391 U. S., at 383. Even when an argument about legislative motive is backed by statements made by legislators who voted for a law, we
