Mr. Justice Stewart
delivered the opinion of the Court.
The petitioners, 187 in number, were convicted in a magistrate’s court in Columbia, South Carolina, of the [230]*230common-law crime of breach of the peace. Their convictions were ultimately affirmed by the South Carolina Supreme Court, 239 S. C. 339, 123 S. E. 2d 247. We granted certiorari, 369 U. S. 870, to consider the claim that these convictions cannot be squared with the Fourteenth Amendment of the United States Constitution.
There was no substantial conflict in the trial evidence.1 Late in the morning of March 2, 1961, the petitioners, high school and college students of the Negro race, met at the Zion Baptist Church in Columbia. From there, at about noon, they walked in separate groups of about 15 to the South Carolina State House grounds, an area of two city blocks open to the general public. Their purpose was “to submit a protest to the citizens of South Carolina, along with the Legislative Bodies of South Carolina, our feelings and our dissatisfaction with the present condition of discriminatory actions against Negroes, in general, and to let them know that we were dissatisfied and that we would like for the laws which prohibited Negro privileges in this State to be removed.”
Already on the State House grounds when the petitioners arrived were 30 or more law enforcement officers, who had advance knowledge that the petitioners were coming.2 Each group of petitioners entered the grounds through a driveway and parking area known in the record as the “horseshoe.” As they entered, they were told by the law enforcement officials that “they had a right, as a citizen, to go through the State House grounds, as any other citizen has, as long as they were peaceful.” Dur[231]*231ing the next half hour or 45 minutes, the petitioners, in the same small groups, walked single file or two abreast in an orderly way3 through the grounds, each group carrying placards bearing such messages as “I am proud to be a Negro” and “Down with segregation.”
During this time a crowd of some 200 to 300 onlookers had collected in the horseshoe area and on the adjacent sidewalks. There was no evidence to suggest that these onlookers were anything but curious, and no evidence at all of any threatening remarks, hostile gestures, or offensive language on the part of any member of the crowd. The City Manager testified that he recognized some of the onlookers, whom he did not identify, as “possible trouble makers,” but his subsequent testimony made clear that nobody among the crowd actually caused or threatened any trouble.4 There was no obstruction of pedes[232]*232trian or vehicular traffic within the State House grounds.5 No vehicle was prevented from entering or leaving the horseshoe area. Although vehicular traffic at a nearby street intersection was slowed down somewhat, an officer was dispatched to keep traffic moving. There were a number of bystanders on the public sidewalks adjacent to the State House grounds, but they all moved on when asked to do so, and there was no impediment of pedestrian traffic.6 Police protection at the scene was at all [233]*233times sufficient to meet any foreseeable possibility of disorder.7
In the situation and under the circumstances thus described, the police authorities advised the petitioners that they would be arrested if they did not disperse within 15 minutes.8 Instead of dispersing, the petitioners engaged in what the City Manager described as “boisterous,” “loud,” and “flamboyant” conduct, which, as his later testimony made clear, consisted of listening to a “religious harangue” by one of their leaders, and loudly singing “The Star Spangled Banner” and other patriotic and religious songs, while stamping their feet and clapping their hands. After 15 minutes had passed, the police arrested the petitioners and marched them off to jail.9
[234]*234Upon this evidence the state trial court convicted the petitioners of breach of the peace, and imposed sentences ranging from a $10 fine or five days in jail, to a $100 fine or 30 days in jail. In affirming the judgments, the Supreme Court of South Carolina said that under the law of that State the offense of breach of the peace “is .not susceptible of exact definition,” but that the “general definition of the offense” is as follows:
“In general terms, a breach of the peace is a violation of public order, a disturbance of the public tranquility, by any act or conduct inciting to violence ... , it includes any violation of any law enacted to preserve peace and good order. It may consist of an act of violence or an act likely to produce violence. It is not necessary that the peace be actually broken to lay the foundation for a prosecution for this offense. If what is done is unjustifiable and unlawful, tending with sufficient directness to break the peace, no more is required. Nor is actual personal violence an essential element in the offense. . . .
“By ‘peace/ as used in the law in this connection, is meant the tranquility enjoyed by citizens of a municipality or community where good order reigns among its members, which is the natural right of all persons in political society.” 239 S. C., at 343-344, 123 S. E. 2d, at 249.
The petitioners contend that there was a complete absence of any evidence of the commission of this offense, and that they were thus denied one of the most basic ele[235]*235ments of due process of law. Thompson v. Louisville, 362 U. S. 199; see Garner v. Louisiana, 368 U. S. 157; Taylor v. Louisiana, 370 U. S. 154. Whatever the merits of this contention, we need not pass upon it in the present case. The state courts have held that the petitioners’ conduct constituted breach of the peace under state law, and we may accept their decision as binding upon us to that extent. But it nevertheless remains our duty in a case such as this to make an independent examination of the whole record. Blackburn v. Alabama, 361 U. S. 199, 205, n. 5; Pennekamp v. Florida, 328 U. S. 331, 335; Fiske v. Kansas, 274 U. S. 380, 385-386. And it is clear to us that in arresting, convicting, and punishing the petitioners under the circumstances disclosed by this record, South Carolina infringed the petitioners’ constitutionally protected rights of free speech, free assembly, and freedom to petition for redress of their grievances.

[234]*234Upon this evidence the state trial court convicted the petitioners of breach of the peace, and imposed sentences ranging from a $10 fine or five days in jail, to a $100 fine or 30 days in jail. In affirming the judgments, the Supreme Court of South Carolina said that under the law of that State the offense of breach of the peace “is .not susceptible of exact definition,” but that the “general definition of the offense” is as follows:
“In general terms, a breach of the peace is a violation of public order, a disturbance of the public tranquility, by any act or conduct inciting to violence ... , it includes any violation of any law enacted to preserve peace and good order.

The petitioners contend that there was a complete absence of any evidence of the commission of this offense, and that they were thus denied one of the most basic ele[235]*235ments of due process of law. Thompson v. Louisville, 362 U. S. 199; see Garner v. Louisiana, 368 U. S. 157; Taylor v. Louisiana, 370 U. S. 154. Whatever the merits of this contention, we need not pass upon it in the present case. The state courts have held that the petitioners’ conduct constituted breach of the peace under state law, and we may accept their decision as binding upon us to that extent. But it nevertheless remains our duty in a case such as this to make an independent examination of the whole record. Blackburn v. Alabama, 361 U. S. 199, 205, n. 5; Pennekamp v. Florida, 328 U. S. 331, 335; Fiske v. Kansas, 274 U. S. 380, 385-386. And it is clear to us that in arresting, convicting, and punishing the petitioners under the circumstances disclosed by this record, South Carolina infringed the petitioners’ constitutionally protected rights of free speech, free assembly, and freedom to petition for redress of their grievances.
It has long been established that these First Amendment freedoms are protected by the Fourteenth Amendment from invasion by the States. Gitlow v. New York, 268 U. S. 652; Whitney v. California, 274 U. S. 357; Stromberg v. California, 283 U. S. 359; De Jonge v. Oregon, 299 U. S. 353; Cantwell v. Connecticut, 310 U. S. 296. The circumstances in this case reflect an exercise of these basic constitutional rights in their most pristine and classic form. The petitioners felt aggrieved by laws of South Carolina which allegedly “prohibited Negro privileges in this State.” They peaceably assembled at the site of the State Government10 and there peaceably expressed their grievances “to the citizens of South Carolina, along with the Legislative Bodies of South Carolina.” [236]*236Not until they were told by police officials that they must disperse on pain of arrest did they do more. Even then, they but sang patriotic and religious songs after one of their leaders had delivered a “religious harangue.” There was no violence or threat of violence on their part, or on the part of any member of the crowd watching them. Police protection was “ample.”
This, therefore, was a far cry from the situation in Feiner v. New York, 340 U. S. 316, where two policemen were faced with a crowd which was “pushing, shoving and milling around,” id., at 317, where at least one member of the crowd “threatened violence if the police did not act,” id., at 317, where “the crowd was pressing, closer around petitioner and the officer,” id., at 318, and where “the speaker passes the bounds of argument or persuasion and undertakes incitement to riot.” Id., at 321. And the record is barren of any evidence of “fighting words.” See Chaplinsky v. New Hampshire, 315 U. S. 568.
We do not review in this case criminal convictions resulting from the evenhanded application of a precise and narrowly drawn regulatory statute evincing a legislative judgment that certain specific conduct be limited or proscribed. If, for example, the petitioners had been convicted upon evidence that they had violated a law regulating traffic, or had disobeyed a law reasonably limiting the periods during which the State House grounds were open to the públic, this would be a different case.11 [237]*237See Cantwell v. Connecticut, 310- U. S. 296, 307-308; Garner v. Louisiana, 368 U. S. 157, 202 (concurring opinion). These petitioners were convicted of an offense so generalized as to be, in the words of the South Carolina Supreme Court, “not susceptible of exact definition.” And they were convicted upon evidence which showed no more than that the opinions which they were peaceably expressing were sufficiently opposed to the views of the majority of the community to attract a crowd and necessitate police protection.
The Fourteenth Amendment does not permit a State to make criminal the peaceful expression of unpopular views. “[A] function of free speech under our system of government is to invite dispute. It may indeed best serve its high purpose when it induces a condition of unrest, creates dissatisfaction with conditions as they are, or even stirs people to anger. Speech is often provocative and challenging. It may strike at prejudices and preconceptions and have profound unsettling effects as it presses for acceptance of an idea. That is why freedom of speech . . . is . . . protected against censorship or punishment, unless shown likely to produce a clear and present danger of a serious substantive evil that rises far above public inconvenience, annoyance, or unrest. . . . There is no room under our Constitution for a more re[238]*238strictive view. For the alternative would lead to standardization of ideas either by legislatures, courts, or dominant political or community groups.” Terminiello v. Chicago, 337 U. S. 1, 4-5. As in the Terminiello ease, the courts of South Carolina have defined a criminal offense so as to permit conviction of the petitioners if their speech “stirred people to anger, invited public dispute, or brought about a condition of unrest. A conviction resting on any of those grounds may not stand.” Id,., at 5.
As Chief Justice Hughes wrote in Stromberg v. California, “The maintenance of the opportunity for free political discussion to the end that government may be responsive to the will of the people and that changes may be obtained by lawful means, an opportunity essential to the security of the Republic, is a fundamental principle of our constitutional system. A statute which upon its face, and as authoritatively construed, is so vague and indefinite as to permit the punishment of the fair use of this opportunity is repugnant to the guaranty of liberty contained in the Fourteenth Amendment. .- . .” 283 U. S. 359, 369.
For these reasons we conclude that these criminal convictions cannot stand.
