MR. JUSTICE FRANKFURTER delivered the opinion of the Court.
This is a suit instituted by the Chase National Bank, a New York corporation, in the federal District Court for the Southern District of Indiana, naming as defendants the Indianapolis Gas Company, the Citizens Gas Company of Indianapolis (Indiana corporations), and the City of Indianapolis. (For brevity's sake the parties will be referred to as Chase, Indianapolis Gas, Citizens Gas, and the City, respectively.) The power of the District Court to entertain this litigation was sustained by the Circuit Court of Appeals for the Seventh Circuit under the provision of the Judicial Code conferring upon the district courts jurisdiction "Of all suits of a civil nature . . . where the matter in controversy exceeds . . . three thousand dollars, and . . . is between citizens of different States . . ." 36 Stat. 1091; 28 U.S.C. § 41 (1). The correctness of this jurisdictional ruling must be determined before the merits of Chase's claims can be considered. The specific question is this: Does an alignment of the parties in relation to their real interests in the "matter in controversy" satisfy the settled requirements of diversity jurisdiction?
As is true of many problems in the law, the answer is to be found not in legal learning but in the realities of the record. Though variously expressed in the decisions, the governing principles are clear. To sustain diversity jurisdiction there must exist an "actual," Helm v. Zarecor, 222 U.S. 32, 36, "substantial," Niles-Bement-Pond Co. v. Iron Moulders Union, 254 U.S. 77, 81, controversy between citizens of different states, all of whom on one side of the controversy are citizens of different states from all parties on the other side. Strawbridge v. Curtiss, 3 Cranch 267. Diversity jurisdiction cannot be conferred upon the federal courts by the parties' own determination of who are plaintiffs and who defendants. It is our duty, as it is that of the lower federal courts, to "look beyond the pleadings and arrange the parties according to their sides in the dispute." Dawson v. Columbia Trust Co., 197 U.S. 178, 180. Litigation is the pursuit of practical ends, not a game of chess. Whether the necessary "collision of interests," Dawson v. Columbia Trust Co., supra, at 181, exists, is therefore not to be determined by mechanical rules. It must be ascertained from the "principal purpose of the suit," Easi Tennessee, V. G.R. v. Grayson, 119 U.S. 240, 244, and the "primary and controlling matter in dispute," Merchants' Cotton Press Co. v. Insurance Co., 151 U.S. 368, 385. These familiar doctrines governing the alignment of parties for purposes of determining diversity of citizenship have consistently guided the lower federal courts and this Court.

English, 246 U.S. 199.
And so we turn to the actualities of this litigation.
Chase is the trustee under a mortgage deed, to secure a bond issue, executed by Indianapolis Gas in 1902. In 1906 Citizens Gas was formed to compete with Indianapolis Gas in the distribution of light, heat, and power to the people of Indianapolis. Its franchise provided that after the expiration of twenty-five years and the performance of certain specified conditions, the company should be wound up and its property conveyed to the City subject to the company's "outstanding legal obligations." The competition between the two gas companies continued until 1913, when Indianapolis Gas leased all of its gas plant property to Citizens Gas for a term of ninety-nine years. Citizens Gas agreed to pay as rental (a) the interest on the lessor's outstanding bonded indebtedness, and (b) annual sums equal to a six per cent return on Indianapolis Gas's common stock. For twenty-two years thereafter Citizens Gas operated the mortgaged property and paid the interest on the bonds. In 1935, pursuant to its franchise, Citizens Gas conveyed its entire property, including that covered by its lease from Indianapolis Gas, to the City. But the City refused to regard itself bound by this lease. On March 2, 1936, the City and Indianapolis Gas agreed that, pending the settlement of the "presently existing controversy" between them as to whether the lease was valid and binding upon the City, the latter would deposit in escrow sums equal to the interest and dividend payments falling due. The agreement expressly provided that it was made without prejudice to either party's "position or rights."
Chase thereupon filed a bill of complaint in the District Court, naming as defendants Indianapolis Gas, Citizens Gas, and the City. It prayed that the lease from Indianapolis Gas to Citizens Gas be declared valid and binding upon the defendants, and as such be deemed part of the security for the performance of the mortgage obligations; that the City be ordered to perform all of the lessee's obligations in the lease and to pay directly to the plaintiff all of the interest payments as they shall become due; that judgment for overdue interest be entered against the defendants "liable therefor"; and that the plaintiff be awarded costs and attorneys' fees. The City and Citizens Gas specifically denied that the lease was valid and binding upon them; they alleged, further, that the controversy existed solely between Indianapolis Gas and the City, "citizens" of the same state. In its answer, Indianapolis Gas denied that it had "ever contended or admitted that the said ninety-nine year lease was not and is not a valid and binding obligation" upon the defendants.
Finding "no collision between the interests of the plaintiff and the interests of the Indianapolis Gas Company," the District Court realigned the latter as a party plaintiff, and finding identity of citizenship between some of the plaintiffs and the remaining defendants, dismissed the suit for want of jurisdiction. The Circuit Court of Appeals reversed, one judge dissenting, 96 F.2d 363, and certiorari was denied, 305 U.S. 600.
On remand to the District Court, Chase filed a supplemental bill alleging default as to interest payments falling due and praying judgment against the defendants in the amount of the unpaid coupons. It alleged that "neither The Indianapolis Gas Company nor Citizens Gas Company, nor both of them, have property sufficient to pay the interest in default on the Bonds, other than the property now in the possession and under the control of the City of Indianapolis." This was admitted by Indianapolis Gas. The District Court held on the merits that the lease was not enforceable against either Citizens Gas or the City; that the former had no power under its franchise to bind the latter to the lease, and that by conveying the leased property to the City, Citizens Gas thereby discharged itself of its lessee obligations. Accordingly, the Court ordered that judgment be entered only against Indianapolis Gas for the amount of the unpaid interest.
Asserting that the District Court erred in not holding the lease valid and enforceable against the defendants, both Chase and Indianapolis Gas appealed. The Circuit Court of Appeals sustained their position and again reversed, 113 F.2d 217. The court held, further, that Chase was entitled to a judgment for unpaid interest against the parties in the following order of liability: the City, Citizens Gas, and Indianapolis Gas. We granted certiorari, 311 U.S. 636, because of the important jurisdictional issue involved in the litigation.
The facts leave no room for doubt that on the merits only one question permeates this litigation: Is the lease whereby Indianapolis Gas in 1913 conveyed all its gas plant property to Citizens Gas valid and binding upon the City? This is the "primary and controlling matter in dispute." The rest is window-dressing designed to satisfy the requirements of diversity jurisdiction. Everything else in the case is incidental to this dominating controversy, with respect to which Indianapolis Gas and the City, "citizens" of the same state, are on opposite sides. That the case presents "only one fundamental issue" and that that is the obligation of the City under the lease, Chase admits and indeed insists upon in its brief on the merits. Chase and Indianapolis Gas have always been united on this issue: both have always contended for the validity of the lease and the City's obligation under it. The opinion of the District Court lays bare the heart of this controversy:
It is contended that, notwithstanding their indissoluble bond on the controlling issue, there are "sufficient matters in controversy" between Chase and Indianapolis Gas to preclude their alignment on the same side. Chase, of course, did not bring this suit in order to obtain a declaration that, regardless of the validity of the lease, Indianapolis Gas is still ultimately responsible for the interest payments on its bonded indebtedness. That was not really in issue, and by its answer, Indianapolis Gas took it out of the case. The further argument is made that, by entering into the escrow agreement with the City, Indianapolis Gas has asserted a claim to the interest payments adverse to that of Chase and the bondholders. But the facts are against this contention. The agreement deals merely with the disposition of the interest falling due during the pendency of the litigation. Moreover, the lease between Indianapolis Gas and Citizens Gas contains no provisions requiring payment of the interest direct to Chase or the bondholders. Nor can diversity jurisdiction be rested upon so flimsy a basis as Chase's prayer for reimbursement of costs and attorneys' fees. The tail flies with the kite.
"There can be no doubt that both plaintiff and the defendant, The Indianapolis Gas Company, have at all times asserted that the lease in question is valid and is binding upon the City, as Trustee. Neither is there any doubt as to their interest in sustaining the validity of such lease at the time of the institution of this action, prior hereto, and at all times subsequent thereto, and that many conferences have been held by and between them, through their attorneys, and many letters have passed between them relating to this subject. . . . Later, when the parties [ i.e., Indianapolis Gas and the City] were unable to adjust their differences and arrive at an agreement, it was decided by The Indianapolis Gas Company and the plaintiff that a suit should be instituted. The common stockholders of that company, of course, had a vital interest in the question of the validity of the lease because, if the lease is valid, they are assured of a six per cent return upon their stock for many years. If, however, a foreclosure suit should have been begun, or if the lease is invalid, no such return is assured. It was natural, therefore, that the Gas Company should take an active interest in the litigation and attempt to guide it along the course that would be most advantageous to it and to its stockholders."
Plainly, therefore, Chase and Indianapolis Gas are, colloquially speaking, partners in litigation. The property covered by the lease is now in the City's possession; Chase is simply acting to protect the bondholders' security. As to Indianapolis Gas, if the lease is upheld, it will continue to receive a six per cent return on its capital, and the burden of paying the interest on its bonded indebtedness will be not upon it but upon the City. What Chase wants, Indianapolis Gas wants, and the City does not want. Yet, the City and Indianapolis Gas were made to have a common interest against Chase when, as a matter of fact, the interests of the City and of Indianapolis Gas are opposed to one another. Therefore, if regard be had to the requirements of jurisdictional integrity, Indianapolis Gas and Chase are on the same side of the controversy not only for their own purposes but also for purposes of diversity jurisdiction. But such realignment places Indiana "citizens" on both sides of the litigation and precludes assumption of jurisdiction based upon diversity of citizenship. We are thus compelled to the conclusion that the District Court was without jurisdiction. And, of course, this Court, by its denial of certiorari when the case was here the first time, could not confer the jurisdiction which Congress has denied.
Compare Dawson v. Columbia Trust Co., 197 U.S. 178, a suit by a Pennsylvania mortgagee of a Georgia waterworks company to restrain a Georgia city from building a new waterworks and to compel specific performance of the city's contract with the waterworks company. The latter was joined as a defendant, on the theory that it was a party to the contract sought to be enforced. The Court held that the bill should be dismissed for lack of jurisdiction: ". . . the court will look beyond the pleadings and arrange the parties according to their sides in the dispute. When that is done it is obvious that the Water Works Company is on the plaintiff's side." 197 U.S. at 180. Ayres v. Wiswall, 112 U.S. 187, and Coney v. Winchell, 116 U.S. 227, are not applicable here. They hold merely that in a foreclosure suit the mortgagee may join the mortgagor and his assignee as defendants; they did not involve any controversy between the mortgagor and the "assignee" as to whether the assignment is binding upon the latter.
Sutton v. English, 246 U.S. 199, clearly holds that the parties must be aligned according to their "attitude towards the actual and substantial controversy." 246 U.S. at 204. The plaintiffs, who included all of the heirs of Mary Jane except Cora, sought to establish their right to certain property claimed to have belonged to Mary Jane. The claimants could not recover unless they proved that a residuary bequest to Cora was invalid — and, with respect to this issue, their position was completely adverse to Cora's. "But, as already pointed out, even could complainants succeed in showing that Mary Jane Hubbard at the time of her death was entitled to the community property, her will giving all the residue of her property to Cora D. Spencer still stands in the way of their succeeding to it as heirs-at-law, and hence their prayer to have that will annulled with respect to the residuary clause is essential to their right to any relief in the suit." 246 U.S. at 207. If the plaintiffs prevailed on this issue of the validity of the residuary gift to Cora, their interests and hers would then be the same with respect to the remaining issues in the case. But the Court held that in relation to the "actual and substantial controversy," Cora and the plaintiffs were on opposite sides, thereby sustaining diversity jurisdiction. In Sutton v. English, alignment of the parties with respect to their real interests sustained diversity; such alignment here precludes jurisdiction. That case and this are applications of the same principle.
This is not a sacrifice of justice to technicality. For the question here is not whether Chase and Indianapolis Gas may pursue what they conceive to be just claims against the City, but whether they may pursue them in the federal courts in Indiana, rather than in its state courts. The fact that Chase prefers the adjudication of its claims by the federal court is certainly no reason why we should deny the plain facts of the controversy and yield to illusive artifices. Settled restrictions against bringing local disputes into the federal courts cannot thus be circumvented.
These requirements, however technical seeming, must be viewed in the perspective of the constitutional limitations upon the judicial power of the federal courts, and of the Judiciary Acts in defining the authority of the federal courts when they sit, in effect, as state courts. See Madisonville Traction Co. v. Mining Co., 196 U.S. 239, 255, and Ex parte Schollenberger, 96 U.S. 369, 377. The dominant note in the successive enactments of Congress relating to diversity jurisdiction, is one of jealous restriction, of avoiding offense to state sensitiveness, and of relieving the federal courts of the overwhelming burden of "business that intrinsically belongs to the state courts," in order to keep them free for their distinctive federal business. See Friendly, The Historic Basis of Diversity Jurisdiction, 41 Harv. L. Rev. 483, 510; Shamrock Oil Corp. v. Sheets, 313 U.S. 100, 108-09; Healy v. Ratta, 292 U.S. 263, 270. "The policy of the statute [conferring diversity jurisdiction upon the district courts] calls for its strict construction. The power reserved to the states, under the Constitution, to provide for the determination of controversies in their courts may be restricted only by the action of Congress in conformity to the judiciary sections of the Constitution. . . . Due regard for the rightful independence of state governments, which should actuate federal courts, requires that they scrupulously confine their own jurisdiction to the precise limits which the statute has defined." Healy v. Ratta, supra, at 270. In defining the boundaries of diversity jurisdiction, this Court must be mindful of this guiding Congressional policy. See Hepburn Dundas v. Ellzey, 2 Cranch 445; New Orleans v. Winter, 1 Wheat. 91; Morris v. Gilmer, 129 U.S. 315, 328-29; Coal Company v. Blatchford, 11 Wall. 172; Shamrock Oil Corp. v. Sheets, 313 U.S. 100; and compare Old Grant v. M'Kee, 1 Pet. 248; Elgin v. Marshall, 106 U.S. 578; Healy v. Ratta, 292 U.S. 263; McNutt v. General Motors Acceptance Corp., 298 U.S. 178.
