diction of a Maryland tribunal.18 See also, e. g., Louisville & N. R. Co. v. Deer, 200 U. S. 176 (1906); Steele v. G. D. Searle & Co., 483 F. 2d 339 (CA5 1973), cert. denied, 415 U. S. 958 (1974).

Pennoyer itself recognized that its rigid categories, even as blurred by the kind of action typified by Harris, could not accommodate some necessary litigation. Accordingly, Mr. Justice Field's opinion carefully noted that cases involving the personal status of the plaintiff, such as divorce actions, could be adjudicated in the plaintiff's home State even though the defendant could not be served within that State. 95 U. S., at 733-735. Similarly, the opinion approved the practice of considering a foreign corporation doing business in a State to have consented to being sued in that State. Id., at 735-736; see Lafayette Ins. Co. v. French, 18 How. 404 (1856). This

18 The Court in Harris limited its holding to States in which the principal defendant (Balk) could have sued the garnishee (Harris) if he had obtained personal jurisdiction over the garnishee in that State. 198 U. S., at 222-223, 226. The Court explained:

"The importance of the fact of the right of the original creditor to sue his debtor in the foreign State, as affecting the right of the creditor of that creditor to sue the debtor or garnishee, lies in the nature of the attachment proceeding. The plaintiff, in such proceeding in the foreign State is able to sue out the attachment and attach the debt due from the garnishee to his (the garnishee's) creditor, because of the fact that the plaintiff is really in such proceeding a representative of the creditor of the garnishee, and therefore if such creditor himself had the right to commence suit to recover the debt in the foreign State his representative has the same right, as representing him, and may garnish or attach the debt, provided the municipal law of the State where the attachment was sued out permits it." Id., at 226.

The problem with this reasoning is that unless the plaintiff has obtained a judgment establishing his claim against the principal defendant, see, e. g., Baltimore & O. R. Co. v. Hostetter, 240 U. S. 620 (1916), his right to "represent" the principal defendant in an action against the garnishee is at issue. See Beale, The Exercise of Jurisdiction in Rem to Compel Payment of a Debt, 27 Harv. L. Rev. 107, 118-120 (1913).

basis for in personam jurisdiction over foreign corporations was later supplemented by the doctrine that a corporation doing business in a State could be deemed "present" in the State, and so subject to service of process under the rule of Pennoyer. See, e. g., International Harvester Co. v. Kentucky, 234 U. S. 579 (1914); Philadelphia & Reading R. Co. v. McKibbin, 243 U. S. 264 (1917). See generally Note, Developments in the Law, State-Court Jurisdiction, 73 Harv. L. Rev. 909, 919-923 (1960) (hereafter Developments).

The advent of automobiles, with the concomitant increase in the incidence of individuals causing injury in States where they were not subject to in personam actions under Pennoyer, required further moderation of the territorial limits on jurisdictional power. This modification, like the accommodation to the realities of interstate corporate activities, was accomplished by use of a legal fiction that left the conceptual structure established in Pennoyer theoretically unaltered. Cf. Olberding v. Illinois Central R. Co., 346 U. S. 338, 340–341 (1953). The fiction used was that the out-of-state motorist, who it was assumed could be excluded altogether from the State's highways, had by using those highways appointed a designated state official as his agent to accept process. See Hess v. Pawloski, 274 U. S. 352 (1927). Since the motorist's "agent" could be personally served within the State, the state courts could obtain in personam jurisdiction over the nonresident driver.

The motorists' consent theory was easy to administer since it required only a finding that the out-of-state driver had used the State's roads. By contrast, both the fictions of implied consent to service on the part of a foreign corporation and of corporate presence required a finding that the corporation was "doing business" in the forum State. Defining the criteria for making that finding and deciding whether they were met absorbed much judicial energy. See, e. g., International Shoe

Co. v. Washington, 326 U. S., at 317-319. While the essentially quantitative tests which emerged from these cases purported simply to identify circumstances under which presence or consent could be attributed to the corporation, it became clear that they were in fact attempting to ascertain "what dealings make it just to subject a foreign corporation to local suit." Hutchinson v. Chase & Gilbert, 45 F. 2d 139, 141 (CA2 1930) (L. Hand, J.). In International Shoe, we acknowledged that fact.

The question in International Shoe was whether the corporation was subject to the judicial and taxing jurisdiction of Washington. Mr. Chief Justice Stone's opinion for the Court began its analysis of that question by noting that the historical basis of in personam jurisdiction was a court's power over the defendant's person. That power, however, was no longer the central concern:

"But now that the capias ad respondendum has given way to personal service of summons or other form of notice, due process requires only that in order to subject a defendant to a judgment in personam, if he be not present within the territory of the forum, he have certain minimum contacts with it such that the maintenance of the suit does not offend 'traditional notions of fair play and substantial justice.' Milliken v. Meyer, 311 U. S. 457, 463." 326 U. S., at 316.

Thus, the inquiry into the State's jurisdiction over a foreign corporation appropriately focused not on whether the corporation was "present" but on whether there have been

"such contacts of the corporation with the state of the forum as make it reasonable, in the context of our federal system of government, to require the corporation to defend the particular suit which is brought there." Id., at 317.

Mechanical or quantitative evaluations of the defendant's activities in the forum could not resolve the question of reasonableness:

"Whether due process is satisfied must depend rather upon the quality and nature of the activity in relation to the fair and orderly administration of the laws which it was the purpose of the due process clause to insure. That clause does not contemplate that a state may make binding a judgment in personam against an individual or corporate defendant with which the state has no contacts, ties, or relations." Id., at 319.19

Thus, the relationship among the defendant, the forum, and the litigation, rather than the mutually exclusive sovereignty of the States on which the rules of Pennoyer rest, became the central concern of the inquiry into personal jurisdiction.20 The immediate effect of this departure from Pennoyer's conceptual apparatus was to increase the ability of the state courts to obtain personal jurisdiction over nonresident defendants. See, e. g., Green, Jurisdictional Reform in California,

19 As the language quoted indicates, the International Shoe Court believed that the standard it was setting forth governed actions against natural persons as well as corporations, and we see no reason to disagree. See also McGee v. International Life Ins. Co., 355 U. S. 220, 222 (1957) (International Shoe culmination of trend toward expanding state jurisdiction over "foreign corporations and other nonresidents"). The differences between individuals and corporations may, of course, lead to the conclusion that a given set of circumstances establishes state jurisdiction over one type of defendant but not over the other.

20 Nothing in Hanson v. Denckla, 357 U. S. 235 (1958), is to the contrary. The Hanson Court's statement that restrictions on state jurisdiction "are a consequence of territorial limitations on the power of the respective States," id., at 251, simply makes the point that the States are defined by their geographical territory. After making this point, the Court in Hanson determined that the defendant over which personal jurisdiction was claimed had not committed any acts sufficiently connected to the State to justify jurisdiction under the International Shoe standard.

21 Hastings L. J. 1219, 1231–1233 (1970); Currie, The Growth of the Long Arm: Eight Years of Extended Jurisdiction in Illinois, 1963 U. Ill. L. F. 533; Developments 1000-1008.

No equally dramatic change has occurred in the law governing jurisdiction in rem. There have, however, been intimations that the collapse of the in personam wing of Pennoyer has not left that decision unweakened as a foundation for in rem jurisdiction. Well-reasoned lower court opinions have questioned the proposition that the presence of property in a State gives that State jurisdiction to adjudicate rights to the property regardless of the relationship of the underlying dispute and the property owner to the forum. See, e. g., U. S. Industries, Inc. v. Gregg, 540 F. 2d 142 (CA3 1976), cert. pending, No. 76–359; Jonnet v. Dollar Savings Bank, 530 F. 2d 1123, 1130-1143 (CA3 1976) (Gibbons, J., concurring); Camire v. Scieszka, 116 N. H. 281, 358 A. 2d 397 (1976); Bekins v. Huish, 1 Ariz. App. 258, 401 P. 2d 743 (1965); Atkinson v. Superior Court, 49 Cal. 2d 338, 316 P. 2d 960 (1957), appeal dismissed and cert. denied sub nom. Columbia Broadcasting System v. Atkinson, 357 U. S. 569 (1958). The overwhelming majority of commentators have also rejected Pennoyer's premise that a proceeding “against" property is not a proceeding against the owners of that property. Accordingly, they urge that the "traditional notions of fair play and substantial justice" that govern a State's power to adjudicate in personam should also govern its power to adjudicate personal rights to property located in the State. See, e. g., Von Mehren & Trautman, Jurisdiction to Adjudicate: A Suggested Analysis, 79 Harv. L. Rev. 1121 (1966) (hereafter Von Mehren & Trautman); Traynor, Is This Conflict Really Necessary?, 37 Texas L. Rev. 657 (1959) (hereafter Traynor); Ehrenzweig, The Transient Rule of Personal Jurisdiction: The "Power" Myth and Forum Conveniens, 65 Yale L. J. 289 (1956); Developments; Hazard.
