We now ask whether any of our precedents forecloses the conclusions we have reached about the meaning of the Second Amendment.

United States v. Cruikshank, 92 U. S. 542, in the course of vacating the convictions of members of a white mob for depriving blacks of their right to keep and bear arms, held that the Second Amendment does not by its own force apply to anyone other than the Federal Government. The opinion explained that the right "is not a right granted by the Constitution [or] in any manner dependent upon that instrument for its existence. The second amendment . . . means no more than that it shall not be infringed by Congress." 92 U. S., at 553. States, we said, were free to restrict or protect the right under their police powers. The limited discussion of the Second Amendment in Cruikshank supports, if anything, the individual-rights interpretation. There was no claim in Cruikshank that the victims had been deprived of their right to carry arms in a militia; indeed, the Governor had disbanded the local militia unit the year before the mob's attack, see C. Lane, The Day Freedom Died 62 (2008). We described the right protected by the Second Amendment as " 'bearing arms for a lawful purpose' "22 and said that "the people [must] look for their protection against any violation by their fellow-citizens of the rights it recognizes" to the States' police power. 92 U. S., at 553. That discussion makes little sense if it is only a right to bear arms in a state militia.23

Presser v. Illinois, 116 U. S. 252 (1886), held that the right to keep and bear arms was not violated by a law that forbade "bodies of men to associate together as military organizations, or to drill or parade with arms in cities and towns unless authorized by law." Id., at 264-265. This does not refute the individual-rights interpretation of the Amendment; no one supporting that interpretation has contended that States may not ban such groups. JUSTICE STEVENS presses Presser into service to support his view that the right to bear arms is limited to service in the militia by joining Presser's brief discussion of the Second Amendment with a later portion of the opinion making the seemingly relevant (to the Second Amendment) point that the plaintiff was not a member of the state militia. Unfortunately for JUSTICE STEVENS' argument, that later portion deals with the Fourteenth Amendment; it was the Fourteenth Amendment to which the plaintiff's nonmembership in the militia was relevant. Thus, JUSTICE STEVENS' statement that Presser "suggested that. . . nothing in the Constitution protected the use of arms outside the context of a militia," post, at 40, is simply wrong.

Presser said nothing about the Second Amendment's meaning or scope, beyond the fact that it does not prevent the prohibition of private paramilitary organizations.

JUSTICE STEVENS places overwhelming reliance upon this Court's decision in United States v. Miller, 307 U. S. 174 (1939). "[H]undreds of judges," we are told, "have relied on the view of the amendment we endorsed there," post, at 2, and "[e]ven if the textual and historical arguments on both side of the issue were evenly balanced, respect for the well-settled views of all of our predecessors on this Court, and for the rule of law itself . . . would prevent most jurists from endorsing such a dramatic upheaval in the law," post, at 4. And what is, according to JUSTICE STEVENS, the holding of Miller that demands such obeisance? That the Second Amendment "protects the right to keep and bear arms for certain military purposes, but that it does not curtail the legislature's power to regulate the nonmilitary use and ownership of weapons." Post, at 2.

Nothing so clearly demonstrates the weakness of JUSTICE STEVENS' case. Miller did not hold that and cannot possibly be read to have held that. The judgment in the case upheld against a Second Amendment challenge two men's federal convictions for transporting an unregistered short-barreled shotgun in interstate commerce, in violation of the National Firearms Act, 48 Stat. 1236. It is entirely clear that the Court's basis for saying that the Second Amendment did not apply was not that the defendants were "bear[ing] arms" not "for . . . military purposes" but for "nonmilitary use," post, at 2. Rather, it was that the type of weapon at issue was not eligible for Second Amendment protection: "In the absence of any evidence tending to show that the possession or use of a [shortbarreled shotgun] at this time has some reasonable relationship to the preservation or efficiency of a well regulated militia, we cannot say that the Second Amendment guarantees the right to keep and bear such an instrument." 307 U. S., at 178 (emphasis added). "Certainly," the Court continued, "it is not within judicial notice that this weapon is any part of the ordinary military equipment or that its use could contribute to the common defense." Ibid. Beyond that, the opinion provided no explanation of the content of the right.

This holding is not only consistent with, but positively suggests, that the Second Amendment confers an individual right to keep and bear arms (though only arms that "have some reasonable relationship to the preservation or efficiency of a well regulated militia"). Had the Court believed that the Second Amendment protects only those serving in the militia, it would have been odd to examine the character of the weapon rather than simply note that the two crooks were not militiamen. JUSTICE STEVENS can say again and again that Miller did "not turn on the difference between muskets and sawed-off shotguns, it turned, rather, on the basic difference between the military and nonmilitary use and possession of guns," post, at 42-43, but the words of the opinion prove otherwise. The most JUSTICE STEVENS can plausibly claim for Miller is that it declined to decide the nature of the Second Amendment right, despite the Solicitor General's argument (made in the alternative) that the right was collective, see Brief for United States, O. T. 1938, No. 696, pp. 4-5. Miller stands only for the proposition that the Second Amendment right, whatever its nature, extends only to certain types of weapons.

It is particularly wrongheaded to read Miller for more than what it said, because the case did not even purport to be a thorough examination of the Second Amendment. JUSTICE STEVENS claims, post, at 42, that the opinion reached its conclusion "[a]fter reviewing many of the same sources that are discussed at greater length by the Court today." Not many, which was not entirely the Court's fault. The respondent made no appearance in the case, neither filing a brief nor appearing at oral argument; the Court heard from no one but the Government (reason enough, one would think, not to make that case the beginning and the end of this Court's consideration of the Second Amendment). See Frye, The Peculiar Story of United States v. Miller, 3 N. Y. U. J. L. & Liberty 48, 65-68 (2008). The Government's brief spent two pages discussing English legal sources, concluding "that at least the carrying of weapons without lawful occasion or excuse was always a crime" and that (because of the class-based restrictions and the prohibition on terrorizing people with dangerous or unusual weapons) "the early English law did not guarantee an unrestricted right to bear arms." Brief for United States, O. T. 1938, No. 696, at 9-11. It then went on to rely primarily on the discussion of the English right to bear arms in Aymette v. State, 21 Tenn. 154, for the proposition that the only uses of arms protected by the Second Amendment are those that relate to the militia, not self-defense. See Brief for United States, O. T. 1938, No. 696, at 12-18. The final section of the brief recognized that "some courts have said that the right to bear arms includes the right of the individual to have them for the protection of his person and property," and launched an alternative argument that "weapons which are commonly used by criminals," such as sawed-off shotguns, are not protected. See id., at 18-21. The Government's Miller brief thus provided scant discussion of the history of the Second Amendment-and the Court was presented with no counterdiscussion. As for the text of the Court's opinion itself, that discusses none of the history of the Second Amendment. It assumes from the prologue that the Amendment was designed to preserve the militia, 307 U. S., at 178 (which we do not dispute), and then reviews some historical materials dealing with the nature of the militia, and in particular with the nature of the arms their members were expected to possess, id., at 178-182. Not a word (not a word) about the history of the Second Amendment. This is the mighty rock upon which the dissent rests its case.24

We may as well consider at this point (for we will have to consider eventually) what types of weapons Miller permits. Read in isolation, Miller's phrase "part of ordinary military equipment" could mean that only those weapons useful in warfare are protected. That would be a startling reading of the opinion, since it would mean that the National Firearms Act's restrictions on machineguns (not challenged in Miller) might be unconstitutional, machineguns being useful in warfare in 1939. We think that Miller's "ordinary military equipment" language must be read in tandem with what comes after: "[O]rdinarily when called for [militia] service [able-bodied] men were expected to appear bearing arms supplied by themselves and of the kind in common use at the time." 307 U. S., at 179. The traditional militia was formed from a pool of men bringing arms "in common use at the time" for lawful purposes like self-defense. "In the colonial and revolutionary war era, [small-arms] weapons used by militiamen and weapons used in defense of person and home were one and the same." State v. Kessler, 289 Ore. 359, 368, 614 P. 2d 94, 98 (1980) (citing G. Neumann, Swords and Blades of the American Revolution 6-15, 252-254 (1973)). Indeed, that is precisely the way in which the Second Amendment's operative clause furthers the purpose announced in its preface. We therefore read Miller to say only that the Second Amendment does not protect those weapons not typically possessed by law-abiding citizens for lawful purposes, such as short-barreled shotguns. That accords with the historical understanding of the scope of the right, see Part III, infra.25

We conclude that nothing in our precedents forecloses our adoption of the original understanding of the Second Amendment. It should be unsurprising that such a significant matter has been for so long judicially unresolved. For most of our history, the Bill of Rights was not thought applicable to the States, and the Federal Government did not significantly regulate the possession of firearms by law-abiding citizens. Other provisions of the Bill of Rights have similarly remained unilluminated for lengthy periods. This Court first held a law to violate the First Amendment's guarantee of freedom of speech in 1931, almost 150 years after the Amendment was ratified, see Near v. Minnesota ex rel. Olson, 283 U. S. 697 (1931), and it was not until after World War II that we held a law invalid under the Establishment Clause, see Illinois ex rel. McCollum v. Board of Ed. of School Dist. No. 71, Champaign Cty., 333 U. S. 203 (1948). Even a question as basic as the scope of proscribable libel was not addressed by this Court until 1964, nearly two centuries after the founding. See New York Times Co. v. Sullivan, 376 U. S. 254 (1964). It is demonstrably not true that, as JUSTICE STEVENS claims, post, at 41-42, "for most of our history, the invalidity of Second-Amendment-based objections to firearms regulations has been well settled and uncontroversial." For most of our history the question did not present itself.

III

Like most rights, the right secured by the Second Amendment is not unlimited. From Blackstone through the 19th-century cases, commentators and courts routinely explained that the right was not a right to keep and carry any weapon whatsoever in any manner whatsoever and for whatever purpose. See, e.g., Sheldon, in 5 Blume 346; Rawle 123; Pomeroy 152-153; Abbott 333. For example, the majority of the 19th-century courts to consider the question held that prohibitions on carrying concealed weapons were lawful under the Second Amendment or state analogues. See, e.g., State v. Chandler, 5 La. Ann., at 489-490; Nunn v. State, 1 Ga., at 251; see generally 2 Kent *340, n. 2; The American Students' Blackstone 84, n. 11 (G. Chase ed. 1884). Although we do not undertake an exhaustive historical analysis today of the full scope of the Second Amendment, nothing in our opinion should be taken to cast doubt on longstanding prohibitions on the possession of firearms by felons and the mentally ill, or laws forbidding the carrying of firearms in sensitive places such as schools and government buildings, or laws imposing conditions and qualifications on the commercial sale of arms.26

We also recognize another important limitation on the right to keep and carry arms. Miller said, as we have explained, that the sorts of weapons protected were those "in common use at the time." 307 U. S., at 179. We think that limitation is fairly supported by the historical tradition of prohibiting the carrying of "dangerous and unusual weapons." See 4 Blackstone 148-149 (1769); 3 B. Wilson, Works of the Honourable James Wilson 79 (1804); J. Dunlap, The New-York Justice 8 (1815); C. Humphreys, A Compendium of the Common Law in Force in Kentucky 482 (1822); 1 W. Russell, A Treatise on Crimes and Indictable Misdemeanors 271-272 (1831); H. Stephen, Summary of the Criminal Law 48 (1840); E. Lewis, An Abridgment of the Criminal Law of the United States 64 (1847); F. Wharton, A Treatise on the Criminal Law of the United States 726 (1852). See also State v. Langford, 10 N. C. 381, 383-384 (1824); O'Neill v. State, 16 Ala. 65, 67 (1849); English v. State, 35 Tex. 473, 476 (1871); State v. Lanier, 71 N. C. 288, 289 (1874).

It may be objected that if weapons that are most useful in military service-M-16 rifles and the like-may be banned, then the Second Amendment right is completely detached from the prefatory clause. But as we have said, the conception of the militia at the time of the Second Amendment's ratification was the body of all citizens capable of military service, who would bring the sorts of lawful weapons that they possessed at home to militia duty. It may well be true today that a militia, to be as effective as militias in the 18th century, would require sophisticated arms that are highly unusual in society at large. Indeed, it may be true that no amount of small arms could be useful against modern-day bombers and tanks. But the fact that modern developments have limited the degree of fit between the prefatory clause and the protected right cannot change our interpretation of the right.

IV

We turn finally to the law at issue here. As we have said, the law totally bans handgun possession in the home. It also requires that any lawful firearm in the home be disassembled or bound by a trigger lock at all times, rendering it inoperable.

As the quotations earlier in this opinion demonstrate, the inherent right of self-defense has been central to the Second Amendment right. The handgun ban amounts to a prohibition of an entire class of "arms" that is overwhelmingly chosen by American society for that lawful purpose. The prohibition extends, moreover, to the home, where the need for defense of self, family, and property is most acute. Under any of the standards of scrutiny that we have applied to enumerated constitutional rights,27 banning from the home "the most preferred firearm in the nation to 'keep' and use for protection of one's home and family," 478 F. 3d, at 400, would fail constitutional muster.

Few laws in the history of our Nation have come close to the severe restriction of the District's handgun ban. And some of those few have been struck down. In Nunn v. State, the Georgia Supreme Court struck down a prohibition on carrying pistols openly (even though it upheld a prohibition on carrying concealed weapons). See 1 Ga., at 251. In Andrews v. State, the Tennessee Supreme Court likewise held that a statute that forbade openly carrying a pistol "publicly or privately, without regard to time or place, or circumstances," 50 Tenn., at 187, violated the state constitutional provision (which the court equated with the Second Amendment). That was so even though the statute did not restrict the carrying of long guns. Ibid. See also State v. Reid, 1 Ala. 612, 616-617 (1840) ("A statute which, under the pretence of regulating, amounts to a destruction of the right, or which requires arms to be so borne as to render them wholly useless for the purpose of defence, would be clearly unconstitutional").

It is no answer to say, as petitioners do, that it is permissible to ban the possession of handguns so long as the possession of other firearms (i.e., long guns) is allowed. It is enough to note, as we have observed, that the American people have considered the handgun to be the quintessential self-defense weapon. There are many reasons that a citizen may prefer a handgun for home defense: It is easier to store in a location that is readily accessible in an emergency; it cannot easily be redirected or wrestled away by an attacker; it is easier to use for those without the upper-body strength to lift and aim a long gun; it can be pointed at a burglar with one hand while the other hand dials the police. Whatever the reason, handguns are the most popular weapon chosen by Americans for self-defense in the home, and a complete prohibition of their use is invalid.

We must also address the District's requirement (as applied to respondent's handgun) that firearms in the home be rendered and kept inoperable at all times. This makes it impossible for citizens to use them for the core lawful purpose of self-defense and is hence unconstitutional. The District argues that we should interpret this element of the statute to contain an exception for self-defense. See Brief for Petitioners 56-57. But we think that is precluded by the unequivocal text, and by the presence of certain other enumerated exceptions: "Except for law enforcement personnel . . . , each registrant shall keep any firearm in his possession unloaded and disassembled or bound by a trigger lock or similar device unless such firearm is kept at his place of business, or while being used for lawful recreational purposes within the District of Columbia." D. C. Code §7-2507.02. The nonexistence of a self-defense exception is also suggested by the D. C. Court of Appeals' statement that the statute forbids residents to use firearms to stop intruders, see McIntosh v. Washington, 395 A. 2d 744, 755-756 (1978).28

Apart from his challenge to the handgun ban and the trigger-lock requirement respondent asked the District Court to enjoin petitioners from enforcing the separate licensing requirement "in such a manner as to forbid the carrying of a firearm within one's home or possessed land without a license." App. 59a. The Court of Appeals did not invalidate the licensing requirement, but held only that the District "may not prevent [a handgun] from being moved throughout one's house." 478 F. 3d, at 400. It then ordered the District Court to enter summary judgment "consistent with [respondent's] prayer for relief." Id., at 401. Before this Court petitioners have stated that "if the handgun ban is struck down and respondent registers a handgun, he could obtain a license, assuming he is not otherwise disqualified," by which they apparently mean if he is not a felon and is not insane. Brief for Petitioners 58. Respondent conceded at oral argument that he does not "have a problem with . . . licensing" and that the District's law is permissible so long as it is "not enforced in an arbitrary and capricious manner." Tr. of Oral Arg. 74-75. We therefore assume that petitioners' issuance of a license will satisfy respondent's prayer for relief and do not address the licensing requirement.

JUSTICE BREYER has devoted most of his separate dissent to the handgun ban. He says that, even assuming the Second Amendment is a personal guarantee of the right to bear arms, the District's prohibition is valid. He first tries to establish this by founding-era historical precedent, pointing to various restrictive laws in the colonial period. These demonstrate, in his view, that the District's law "imposes a burden upon gun owners that seems proportionately no greater than restrictions in existence at the time the Second Amendment was adopted." Post, at 2. Of the laws he cites, only one offers even marginal support for his assertion. A 1783 Massachusetts law forbade the residents of Boston to "take into" or "receive into" "any Dwelling House, Stable, Barn, Out-house, Ware-house, Store, Shop or other Building" loaded firearms, and permitted the seizure of any loaded firearms that "shall be found" there. Act of Mar. 1, 1783, ch. 13, 1783 Mass. Acts p. 218. That statute's text and its prologue, which makes clear that the purpose of the prohibition was to eliminate the danger to firefighters posed by the "depositing of loaded Arms" in buildings, give reason to doubt that colonial Boston authorities would have enforced that general prohibition against someone who temporarily loaded a firearm to confront an intruder (despite the law's application in that case). In any case, we would not stake our interpretation of the Second Amendment upon a single law, in effect in a single city, that contradicts the overwhelming weight of other evidence regarding the right to keep and bear arms for defense of the home. The other laws JUSTICE BREYER cites are gunpowder-storage laws that he concedes did not clearly prohibit loaded weapons, but required only that excess gunpowder be kept in a special container or on the top floor of the home. Post, at 6-7. Nothing about those fire-safety laws undermines our analysis; they do not remotely burden the right of self-defense as much as an absolute ban on handguns. Nor, correspondingly, does our analysis suggest the invalidity of laws regulating the storage of firearms to prevent accidents.

JUSTICE BREYER points to other founding-era laws that he says "restricted the firing of guns within the city limits to at least some degree" in Boston, Philadelphia and New York. Post, at 4 (citing Churchill, Gun Regulation, the Police Power, and the Right to Keep Arms in Early America, 25 Law & Hist. Rev. 139, 162 (2007)). Those laws provide no support for the severe restriction in the present case. The New York law levied a fine of 20 shillings on anyone who fired a gun in certain places (including houses) on New Year's Eve and the first two days of January, and was aimed at preventing the "great Damages . . . frequently done on [those days] by persons going House to House, with Guns and other Firearms and being often intoxicated with Liquor." 5 Colonial Laws of New York 244-246 (1894). It is inconceivable that this law would have been enforced against a person exercising his right to self-defense on New Year's Day against such drunken hooligans. The Pennsylvania law to which JUSTICE BREYER refers levied a fine of 5 shillings on one who fired a gun or set off fireworks in Philadelphia without first obtaining a license from the governor. See Act of Aug. 26, 1721, §4, in 3 Stat. at Large 253-254. Given Justice Wilson's explanation that the right to self-defense with arms was protected by the Pennsylvania Constitution, it is unlikely that this law (which in any event amounted to at most a licensing regime) would have been enforced against a person who used firearms for self-defense. JUSTICE BREYER cites a Rhode Island law that simply levied a 5-shilling fine on those who fired guns in streets and taverns, a law obviously inapplicable to this case. See An Act for preventing Mischief being done in the town of Newport, or in any other town in this Government, 1731, Rhode Island Session Laws. Finally, JUSTICE BREYER points to a Massachusetts law similar to the Pennsylvania law, prohibiting "discharg[ing] any Gun or Pistol charged with Shot or Ball in the Town of Boston." Act of May 28, 1746, ch. X, Acts and Laws of Mass. Bay 208. It is again implausible that this would have been enforced against a citizen acting in self-defense, particularly given its preambulatory reference to "the indiscreet firing of Guns." Ibid. (preamble) (emphasis added).

A broader point about the laws that JUSTICE BREYER cites: All of them punished the discharge (or loading) of guns with a small fine and forfeiture of the weapon (or in a few cases a very brief stay in the local jail), not with significant criminal penalties.29 They are akin to modern penalties for minor public-safety infractions like speeding or jaywalking. And although such public-safety laws may not contain exceptions for self-defense, it is inconceivable that the threat of a jaywalking ticket would deter someone from disregarding a "Do Not Walk" sign in order to flee an attacker, or that the Government would enforce those laws under such circumstances. Likewise, we do not think that a law imposing a 5-shilling fine and forfeiture of the gun would have prevented a person in the founding era from using a gun to protect himself or his family from violence, or that if he did so the law would be enforced against him. The District law, by contrast, far from imposing a minor fine, threatens citizens with a year in prison (five years for a second violation) for even obtaining a gun in the first place. See D. C. Code §7-2507.06.

JUSTICE BREYER moves on to make a broad jurisprudential point: He criticizes us for declining to establish a level of scrutiny for evaluating Second Amendment restrictions. He proposes, explicitly at least, none of the traditionally expressed levels (strict scrutiny, intermediate scrutiny, rational basis), but rather a judge-empowering "interest-balancing inquiry" that "asks whether the statute burdens a protected interest in a way or to an extent that is out of proportion to the statute's salutary effects upon other important governmental interests." Post, at 10. After an exhaustive discussion of the arguments for and against gun control, JUSTICE BREYER arrives at his interest-balanced answer: because handgun violence is a problem, because the law is limited to an urban area, and because there were somewhat similar restrictions in the founding period (a false proposition that we have already discussed), the interest-balancing inquiry results in the constitutionality of the handgun ban. QED.

We know of no other enumerated constitutional right whose core protection has been subjected to a freestanding "interest-balancing" approach. The very enumeration of the right takes out of the hands of government-even the

Third Branch of Government-the power to decide on a case-by-case basis whether the right is really worth insisting upon. A constitutional guarantee subject to future judges' assessments of its usefulness is no constitutional guarantee at all. Constitutional rights are enshrined with the scope they were understood to have when the people adopted them, whether or not future legislatures or (yes) even future judges think that scope too broad. We would not apply an "interest-balancing" approach to the prohibition of a peaceful neo-Nazi march through Skokie. See National Socialist Party of America v. Skokie, 432 U. S. 43 (1977) (per curiam). The First Amendment contains the freedom-of-speech guarantee that the people ratified, which included exceptions for obscenity, libel, and disclosure of state secrets, but not for the expression of extremely unpopular and wrong-headed views. The Second Amendment is no different. Like the First, it is the very product of an interest-balancing by the people-which JUSTICE BREYER would now conduct for them anew. And whatever else it leaves to future evaluation, it surely elevates above all other interests the right of law-abiding, responsible citizens to use arms in defense of hearth and home.
JUSTICE BREYER chides us for leaving so many applications of the right to keep and bear arms in doubt, and for not providing extensive historical justification for those regulations of the right that we describe as permissible. See post, at 42-43. But since this case represents this Court's first in-depth examination of the Second Amendment, one should not expect it to clarify the entire field, any more than Reynolds v. United States, 98 U. S. 145 (1879), our first in-depth Free Exercise Clause case, left that area in a state of utter certainty. And there will be time enough to expound upon the historical justifications for the exceptions we have mentioned if and when those exceptions come before us.
