Opinion of the Court
Allen v. State Bd. of Elections, 393 U. S. 544, 569 (1969) (emphasis added). Where members of a racial minority group
vote as a cohesive unit, practices such as multimember or atlarge electoral systems can reduce or nullify minority voters'
ability, as a group, "to elect the candidate of their choice."
Ibid. Accordingly, the Court held that such schemes violate
the Fourteenth Amendment when they are adopted with a
discriminatory purpose and have the effect of diluting minority voting strength. See, e. g., Rogers v. Lodge, 458 U. S.
613, 616-617 (1982); White v. Regester, 412 U. S. 755, 765-766
(1973). Congress, too, responded to the problem of vote dilution. In 1982, it amended § 2 of the Voting Rights Act to
prohibit legislation that results in the dilution of a minority
group's voting strength, regardless of the legislature's intent.
42 U. S. C. § 1973; see Thornburg v. Gingles, 478 U. S. 30
(1986) (applying amended § 2 to vote-dilution claim involving
multimember districts); see also Voinovich v. Quilter, 507
U. S. 146, 155 (1993) (single-member districts).

It is against this background that we confront the questions presented here. In our view, the District Court properly dismissed appellants' claims against the federal appellees. Our focus is on appellants' claim that the State
engaged in unconstitutional racial gerrymandering. That
argument strikes a powerful historical chord: It is unsettling
how closely the North Carolina plan resembles the most
egregious racial gerrymanders of the past.
.An understanding of the nature of appellants' claim is critical to our resolution of the case. In their complaint, appellants did not claim that the General Assembly's reapportionment plan unconstitutionally "diluted" white voting
strength. They did not even claim to be white. Rather, appellants' complaint alleged that the deliberate segregation of
voters into separate districts on the basis of race violated
their constitutional right to participate in a "color-blind"
