Cite as: 541 U. S. 509 (2004) Opinion of the Court services, programs, and activities, which are the subject of Title II; and public accommodations, which are covered by Title III. Title II, §§ 12131-12134, prohibits any public entity from discriminating against "qualified" persons with disabilities in the provision or operation of public services, programs, or activities. The Act defines the term "public entity" to include state and local governments, as well as their agencies and instrumentalities. § 12131(1). Persons with disabilities are "qualified" if they, "with or without reasonable modifications to rules, policies, or practices, the removal of architectural, communication, or transportation barriers, or the provision of auxiliary aids and services, mee[t] the essential eligibility requirements for the receipt of services or the participation in programs or activities provided by a public entity." § 12131(2). Title II's enforcement provision incorporates by reference § 505 of the Rehabilitation Act of 1973, 92 Stat. 2982, as added, 29 U. S. C. § 794a, which authorizes private citizens to bring suits for money damages. 42 U. S. C. § 12133. III The Eleventh Amendment renders the States immune from "any suit in law or equity, commenced or prosecuted ... by Citizens of another State, or by Citizens or Subjects of any Foreign State." Even though the Amendment "by its terms . . . applies only to suits against a State by citizens of another State," our cases have repeatedly held that this immunity also applies to unconsented suits brought by a State's own citizens. Garrett, 531 U. S., at 363; Kimel v. Florida Bd. of Regents, 528 U. S. 62, 72-73 (2000). Our cases have also held that Congress may abrogate the State's Eleventh Amendment immunity. To determine whether it has done so in any given case, we "must resolve two predicate questions: first, whether Congress unequivocally expressed its intent to abrogate that immunity; and second, if it did, whether Congress acted pursuant to a valid grant of constitutional authority." Id., at 73.
