delivered the opinion of the Court.
This case concerns the authority of the federal courts to adjudicate controversies. Jurisdiction to resolve cases on the merits requires both authority over the category of claim in suit (subject-matter jurisdiction) and authority over the parties (personal jurisdiction), so that the court’s decision will bind them. In
Steel Co.
v.
Citizens for Better Environment,
Steel Co. is the backdrop for the issue now before us: If, as Steel Co. held, jurisdiction generally must precede merits in dispositional order, must subject-matter jurisdiction precede personal jurisdiction on the decisional line? Or, do federal district courts have discretion to avoid a difficult question *578 of subject-matter jurisdiction when the absence of personal jurisdiction is the surer ground? The particular civil action we confront was commenced in state court and removed to federal court. The specific question on which we granted certiorari asks “[wjhether a federal district court is absolutely barred in all circumstances from dismissing a removed case for lack of personal jurisdiction without first deciding its subject-matter jurisdiction.” Pet. for Cert. i.
We hold that in cases court, as in cases originating in federal court, there is no unyielding jurisdictional hierarchy. Customarily, a federal court first resolves doubts about its jurisdiction over the subject matter, but there are circumstances in which a district court appropriately accords priority to a personal jurisdiction inquiry. The proceeding before us is such a ease.

The underlying controversy stems from a venture to produce gas in the Heimdal Field of the Norwegian North Sea. In 1976, respondents Marathon Oil Company and Marathon International Oil Company acquired Marathon Petroleum Company (Norway) (MPCN) and respondent Marathon Petroleum Norge (Norge). See App. 26. 1 Before the acquisition, Norge held a license to produce gas in the Heimdal Field; following the transaction, Norge assigned the license to MPCN. See Record, Exhs. 61 and 62 to Document 64. In 1981, MPCN contracted to sell 70% of its share of the Heimdal gas production to a group of European buyers, including petitioner Ruhrgas AG. See Record, Exh. 1 to Document 63, pp. 90, 280. The parties’ agreement was incor *579 porated into the Heimdal Gas Sales Agreement (Heimdal Agreement), which is “governed by and construed in accordance with Norwegian Law,” Record, Exh. B, Tab 1 to Pet. for Removal, Heimdal Agreement, p. 102; disputes thereunder are to be “exclusively and finally ... settled by arbitration in Stockholm, Sweden, in accordance with” International Ghamber of Commerce rules, id., at 100.

Marathon Oil Company, Marathon International Oil Company, and Norge (collectively, Marathon) filed this lawsuit against Ruhrgas in Texas state court on July 6, 1995, asserting state-law claims of fraud, tortious interference with prospective business relations, participation in breach of fiduciary duty, and civil conspiracy. See App. 38-40. Marathon Oil Company and Marathon International Oil Company alleged that Ruhrgas and the other European buyers induced them with false promises of “premium prices” and guaranteed pipeline tariffs to invest over $300 million in MPGN for the development of the Heimdal Field and the erection of a pipeline to Ruhrgas’ plant in Germany. See id., at 26-28; Brief for Respondents 1-2. Norge alleged that Ruhrgas’ effective monopolization of the Heimdal gas diminished the value of the license Norge had assigned to MPCN. See App. 31, 33, 357; Brief for Respondents 2. Marathon asserted that Ruhrgas had furthered its plans at three meetings in Houston, Texas, and through a stream of correspondence directed to Marathon in Texas. See App. 229, 233.

After permitting Court dismissed the case for lack of personal jurisdiction. See App. 455. In so ruling, the District Court relied on Fifth Circuit precedent allowing district courts to adjudicate personal jurisdiction without first establishing subject-matter jurisdiction. See

v.
Middleton,
A panel of the Court of Appeals for the Fifth Circuit concluded that “respec[t]” for “the proper balance of federalism” impelled it to turn first to “the formidable subject matter jurisdiction issue presented.”
The Fifth Circuit, on its own motion, granted rehearing en banc, thereby vacating the panel decision. See
Writing for the seven dissenters, Judge Higginbotham agreed that subject-matter jurisdiction ordinarily should be considered first. See
id.,
at 231. If the challenge to personal jurisdiction involves no complex state-law questions, however, and is more readily resolved than the challenge to subject-matter jurisdiction, the District Court, in the dissenters’ view, should take the easier route. See
ibid.
Judge Higginbotham regarded the District Court’s decision dismissing Marathon’s case as illustrative and appropriate: While Ruhrgas’ argument under 9 U. S. C. § 205 presented a difficult issue of first impression, its personal jurisdiction challenge raised “[n]o substantial questions of purely state law,” and “could be resolved relatively easily in [Ruhrgas’] favor.”

Steel Co.
held that Article III generally requires a federal court to satisfy itself of its jurisdiction over the subject matter before it considers the merits of a ease. “For a court to pronounce upon [the merits] when it has no jurisdiction to do so,”
Steel Co.
declared, “is ... for a court to act ultra vires.”

The Court of Appeals accorded priority to the requirement of subject-matter jurisdiction because it is nonwaivable and delimits federal-court power, while restrictions on a court’s jurisdiction over the person are waivable and protect individual rights. See
id.,
at 217-218. The character of the two jurisdictional bedrocks unquestionably differs. Subject-matter limitations on federal jurisdiction serve institutional interests. They keep the federal courts within the bounds the Constitution and Congress have prescribed. Accordingly, subject-matter delineations must be policed by the courts on their own initiative even at the highest level. See

These distinctions do not mean that diction is ever and always the more “fundamental.” Personal jurisdiction, too, is “an essential element of the jurisdiction of a district . . . court,” without which the court is “powerless to proceed to an adjudication.”

reasoned that subjeet-matter necessarily precedes a ruling on the merits, the same principle does not dictate a sequencing of jurisdictional issues. “[A] court that dismisses on . . . non-merits grounds such as . . . personal jurisdiction, before finding subject-matter jurisdiction, makes no assumption of law-declaring power

Maintaining that subject-matter jurisdiction must be decided first even when the litigation originates in federal court, see Tr. of Oral Arg. 21; Brief for Respondents 13, Marathon sees removal as the more offensive case, on the ground that the dignity of state courts is immediately at stake. If a federal court dismisses a removed case for want of personal jurisdiction, that determination may preclude the parties from relitigating the very same personal jurisdiction issue in state court. See
Baldwin
v.
Iowa State Traveling Men’s
Assn.,
in subsequent state-court litigation, however, may also attend a federal court’s subject-matter determination. Ruhrgas hypothesizes, for example, a defendant who removes on diversity grounds a state-court suit seeking $50,000 in compensatory and $1 million in punitive damages for breach of contract. See Tr. of Oral Arg. 10-11. If the district court determines that state law does not allow puni
*586
tive damages for breach of contract and therefore remands the removed action for failure to satisfy the amount in controversy, see 28 U. S. C. § 1332(a) (1994 ed., Supp. III) ($75,000), the federal court’s conclusion will travel back with the ease. Assuming a fair airing of the issue in federal court, that court’s ruling on permissible state-law damages may bind the parties in state court, although it will set no precedent otherwise governing state-court adjudications.

v.
Baxter State Bank,
Most essentially, federal tary systems for administering justice in our Nation. Cooperation and comity, not competition and conflict, are essential to the federal design. A State’s dignitary interest bears consideration when a district court exercises discretion in a case cf this order. If personal jurisdiction raises “difficult questions of [state] law,” and subject-matter jurisdiction is resolved “as eas[ily]” as personal jurisdiction, a district court will ordinarily conclude that “federalism concerns tip the scales in favor of initially ruling on the motion to remand.”

Ferguson,
“does not mean blind deference to 'States’ Rights’ any more than it means centralization of control over every important issue in our National Government and its courts. The Framers rejected both these courses. What the concept does represent is a system in which there is sensitivity to the legitimate interests of both State and National Governments.” Younger,401 U. S., at 44 .
The Fifth Gircuit and Marathon posit that state-court defendants will abuse the federal system with opportunistic removals. A discretionary rule, they suggest, will encourage manufactured, convoluted federal subject-matter theories designed to wrench eases from state court. See

In accord with Judge Higginbotham, we recognize that in most instances subject-matter jurisdiction will involve no arduous inquiry. See

It is so ordered.
Notes
Ruhrgas is a German corporation; Norge is a Norwegian corporation. See App. 21,22. Marathon Oil Company, an Ohio corporation, and Marathon International Oil Company, a Delaware corporation, moved their principal places of business from Ohio to Texas while the venture underlying this case was in formation. See id., at 21, 239, and n. 11.
A suit between “citizens of a State and citizens or subjects of a foreign state” lies within federal diversity jurisdiction. 28 U. S. C. § 1332(a)(2). Section 1332 has been interpreted to require “complete diversity.” See
Strawbridge
v.
Curtiss,
Title 9 U. S. C. §205 allows removal "[wjhere the subject matter of an action or proceeding pending in a State court relates to an arbitration agreement or award falling under the Convention [on the Recognition and Enforcement of Foreign Arbitral Awards of June 10,1958].”
Respecting the three meetings Ruhrgas attended in Houston, Texas, see
supra,
at 579, the District Court concluded that Marathon had not shown that Ruhrgas pursued the alleged pattern of fraud and misrepresentation during the Houston meetings. See App. 449. The court further found that Ruhrgas attended those meetings “due to the [Heimdal Agreement] with MPCN.”
Id.,
at 450. As the Heimdal Agreement provides for arbitration in Sweden, the court reasoned, “Ruhrgas could not have expected to be haled into Texas courts based on these meetings.”
Ibid.
The court also determined that Ruhrgas did not have “systematic and continuous contacts with Texas” of the kind that would “subject it to general jurisdiction in Texas.”

v.
Hall,
The Court of Appeals concluded that whether Norge had a legal interest in the Heimdal license notwithstanding its assignment to MPCN likely turned on difficult questions of Norwegian law; Ruhrgas therefore could not show, at the outset, that Norge had been fraudulently joined as a plaintiff to defeat diversity. See
The Fifth Circuit remanded the case to the District Court for it to consider the “nove[l]” subject-matter jurisdiction issues presented.
The Court of Appeals for the Second Circuit has concluded that district courts have discretion to dismiss a removed case for want of personal jurisdiction without reaching the issue of subject-matter jurisdiction. See

v.
Peaslee,
Ruhrgas suggests that it would be appropriate simply to affirm the District Court's holding that it lacked personal jurisdiction over Ruhrgas. See Brief for Petitioner 38-39, and n. 20. That issue is not within the question presented and is properly considered by the Fifth Circuit on remand.
