delivered the opinion of the Court.
This litigation began in 1951 when a group of Negro school children living in Prince Edward County, Virginia, filed a complaint in the United States District Court for the Eastern District of Virginia alleging that they had been denied admission to public schools attended by white children and charging that Virginia laws requiring such school segregation denied complainants the equal protec
*353
tion of the laws in violation of the Fourteenth Amendment. On May 17, 1954, ten years ago, we held that the Virginia segregation laws did deny equal protection.
Brown
v.
Board of Education,
Efforts to desegregate Prince Edward County’s schools met with resistance. In 1956 Section 141 of the Virginia Constitution was amended to authorize the General Assembly and local governing bodies to appropriate funds to assist students to go to public or to nonsectarian private schools, in addition to those owned by the State or by the locality.
1
The General Assembly met in special session and enacted legislation to close any public schools where white and colored children were enrolled together, to cut off state funds to such schools, to pay tuition grants to children in nonsectarian private schools, and to extend state retirement benefits to teachers in newly created private schools.
2
The legislation closing mixed schools and cutting off state funds was later invalidated by the Supreme Court of Appeals of Virginia, which held that these laws violated the Virginia Constitution.
Harrison
v.
Day,
In June 1959, the United States Court of Appeals for the Fourth Circuit directed the Federal District Court (1) to enjoin discriminatory practices in Prince Edward County schools, (2) to require the County School Board to take “immediate steps” toward admitting students without regard to race to the white high school “in the school term beginning September 1959,” and (3) to require the Board to make plans for admissions to elementary schools without regard to race.
Allen
v.
County School Board of Prince Edward County,
In 1961 petitioners here filed a supplemental complaint, adding new parties and seeking to enjoin the respondents from refusing to operate an efficient system of public free schools in Prince Edward County and to enjoin payment of public funds to help support private schools which excluded students on account of race. The District Court, finding that “the end result of every action taken by that body [Board of Supervisors] was designed to preserve separation of the races in the schools of Prince Edward County,” enjoined the county from paying tuition grants or giving tax credits so long as public schools remained closed.

Allen
v.
County School Board of Prince Edward County,
“In view of the long delay in the case since our decision in the Brown case and the importance of the questions presented, we grant certiorari and put the case down for argument March 30,1964, on the merits, as we have done in other comparable situations without waiting for final action by the Court of Appeals.”375 U. S. 391 , 392.
For reasons to be stated, we agree with the District Court that, under the circumstances here, closing the Prince Edward County schools while public schools in all the other counties of Virginia were being maintained denied the petitioners and the class of Negro students they represent the equal protection of the laws guaranteed by the Fourteenth Amendment.
*358 I.
Before reaching the substantial questions presented, we shall note several procedural matters urged by respondents in a motion to dismiss the supplemental amended complaint filed July 7, 1961 — ten years after this action was instituted. Had the motion to dismiss been granted on any of the grounds assigned, the result would have been one more of what Judge Bell, dissenting in the Court of Appeals, referred to as “the inordinate delays which have already occurred in this protracted litigation . . . .”
(a) It is contended that the amended supplemental complaint presented a new and different cause of action from that presented in the original complaint. The supplemental pleading did add new parties and rely in good part on transactions, occurrences, and events which had happened since the action had begun. But these new transactions were alleged to have occurred as a part of continued, persistent efforts to circumvent our 1955 holding that Prince Edward County could not continue to operate, maintain, and support a system of schools in which students were segregated on a racial basis. The original complaint had challenged racial segregation in schools which were admittedly public. The new complaint charged that Prince Edward County was still using its funds, along with state funds, to assist private schools while at the same time closing down the county’s public, schools, all to avoid the desegregation ordered in the Brown cases. The amended complaint thus was not a new cause of action but merely part of the same old cause of action arising out of the continued desire of colored students in Prince Edward County to have the same opportunity for state-supported education afforded to white people, a desire thwarted before 1959 by segre *359 gation in the public schools and after 1959 by a combination of closed public schools and state and county grants to white children at the Foundation’s private schools. Rule 15 (d) of the Federal Rules of Civil Procedure plainly permits supplemental amendments to cover events happening after suit, 11 and it follows, of course, that persons participating in these new events may be added if necessary. Such amendments are well within the basic aim of the rules to make pleadings a means to achieve an orderly and fair administration of justice.
(b) When this action was originally brought in 1951, it broadly charged that the constitution and laws of Virginia provided a state system of public schools which unconstitutionally segregated school children on the basis of color. This challenge was heard by a District Court of three judges as required by 28 U. S. C. § 2281. When in
Brown
we held the school segregation laws invalid as a denial of equal protection of the laws under the Fourteenth Amendment and remanded for the District Court to fashion a decree requiring abandonment of segregation “with all deliberate speed,” the three-judge court ceased to function, and a single district judge took over. Respondents contend that the single judge erroneously passed on the issues raised by the supplemental complaint and that we should now delay the case still further by vacating his judgment along with that of the Court of Appeals and remanding to the District Court for a completely new trial before three judges. We reject the contention. In
Rorick
v.
Board of Comm’rs of Everglades Drainage Dist.,
“ ‘Despite the generality of the language' of that Section, it is now settled doctrine that only a suit involving ‘a statute of general application’ and not one affecting a ‘particular municipality or district’ can invoke § 266.”
While a holding as to the constitutional duty of the Supervisors and other officials of Prince Edward County may have repercussions over the State and may require the District Court’s orders to run to parties outside the county, it is nevertheless true that what is attacked in this suit is not something which the State has commanded Prince Edward to do — close its public schools and give grants to children in private schools — but rather something which the county with state acquiescence and cooperation has undertaken to do on its own volition, a decision not binding on any other county in Virginia. Even though actions of the State are involved, the case, as it comes to us, concerns not a state-wide system but rather a situation unique to Prince Edward County. We hold that the single district judge did not err in adjudicating this present controversy.
(c) It is contended that the case is an action against the State, is forbidden by the Eleventh Amendment, and therefore should be dismissed. The complaint, however, charged that state and county officials were depriving petitioners of rights guaranteed by the Fourteenth Amendment. It has been settled law since

(d) It is argued that the District Court should have abstained from passing on the issues raised here in order to await a determination by the Supreme Court of Appeals of Virginia as to whether the conduct complained

County School Board of Prince Edward County
v.
Griffin,
Since 1959, all Virginia counties have had the benefits of public schools but one: Prince Edward. However, there is no rule that counties, as counties, must be treated alike; the Equal Protection Clause relates to equal protection of the laws “between persons as such rather than between areas.”
Salsburg
v.
Maryland,
Virginia law, as here applied, unquestionably treats the school children of Prince Edward differently from the way it treats the school children of all other Virginia counties. Prince Edward children must go to a private school or none at all; all other Virginia children can go to public schools. Closing Prince Edward’s schools bears more heavily on Negro children in Prince Edward County since white children there have accredited private schools which they can attend, while colored children until very recently have had no available private schools, and even the school they now attend is a temporary expedient. Apart from this expedient, the result is that Prince Edward County school children, if they go to school in their own county, must go to racially segregated schools which, although *363 designated as private, are beneficiaries of county and state support.
A State, of course, has a wide discretion in deciding whether laws shall operate statewide or shall operate only in certain counties, the legislature “having in mind the needs and desires of each.”

Hall
v.
St. Helena Parish School Board,
III.
We come now to the question of the kind of decree lecessary and appropriate to put an end to the racial discrimination practiced against these petitioners under authority of the Virginia laws. That relief needs to be quick and effective. The parties defendant are the Board of Supervisors, School Board, Treasurer, and Division Superintendent of Schools of Prince Edward County, and the State Board of Education and the State Superintendent of Education. All of these have duties which relate directly or indirectly to the financing, supervision, or operation of the schools in Prince Edward County. The Board of Supervisors has the special responsibility to levy local taxes to operate public schools or to aid children attending the private schools now functioning there for white children. The District Court enjoined the county officials from paying county tuition grants or giving tax exemptions and from processing applications for state tuition grants so long as the county’s public schools remained closed. We have no doubt of the power of the
*365
court to give this relief to enforce the discontinuance of the county’s racially discriminatory practices. It has long been established that actions against a county can be maintained in United States courts in order to vindicate federally guaranteed rights.
E. g., Lincoln County
v.
Luning,
The District Court held that “the public schools of Prince Edward County may not be closed to avoid the effect of the law of the land as interpreted by the Supreme Court, while the Commonwealth of Virginia permits other public schools to remain open at the expense of the taxpayers.”
Allen
v.
County School Board of Prince Edward County,
The judgment of the Court of Appeals is reversed, the judgment of the District Court is affirmed, and the cause is remanded to the District Court with directions to enter a decree which will guarantee that these petitioners will get the kind of education that is given in the State’s public schools. And, if it becomes necessary to add new parties to accomplish this end, the District Court is free to do so.
It is so ordered.
Notes
Virginia tuition grants originated in 1930 as aid to children who had lost their fathers in World War I. The program was expanded until the Supreme Court of Appeals of Virginia held that giving grants to children attending private schools violated the Virginia Constitution.

Day,
Va. Code, §22-188.3 et seq.; §51-111.38:1.
Acts, 1959 Ex. Sess., c. 53.
Va. Code, §§22-251 to 22-275.
Va. Code, §§22-275.1 to 22-275.25.
The Board’s public explanation of its June 3, 1959, refusal to appropriate money or levy taxes to carry on the county’s public school system was:
“The School Board of this county is confronted with a court decree which requires the admission of white and colored children to all the schools of the county without regard to race or color. Knowing the people of this county as we do, we know that it is not possible to operate the schools of this county within the terms of that principle and, at the same time, maintain an atmosphere conducive to the educational benefit of our people.”
Va. Code, §§ 22-115.29 to 22-115.35.
On the question of the validity of state tuition grants, the court held that, as a matter of state law, such grants were not meant to be given in localities without public schools; therefore, the court enjoined the county from processing applications for state grants so long as public schools remained closed.
The Supreme Court of Appeals of Virginia had, in a mandamus proceeding instituted by petitioners, held that the State Constitution and statutes did not impose upon the County Board of Supervisors any mandatory duty to levy taxes and appropriate money to support free public schools.
Griffin
v.
Board of Supervisors of Prince Edward County,
In the meantime, the Supreme Court of Appeals of Virginia had held that the Virginia Constitution did not compel the State to reopen public schools in Prince Edward County.

“But it should go without saying that the vitality of these constitutional principles cannot be allowed to yield simply because of disagreement with them.”
