BACKGROUND
Ysleta Del Sur Pueblo (the “Tribe” or the “Pueblo”), a federally recognized Indi-an Tribe, filed suit in federal district court, seeking to eject David M. Laney, Robert L. Nichols, Anne S. Wynne, Eddie Sanchez, and Rudy Lugo, present commissioners of the Texas Transportation Commission, and two employees of the Texas Department of Transportation, in their individual capacities (“Appellants”), from a piece of real property (the “Property”) which currently serves as a highway maintenance facility in El Paso County, Texas. The tribe also requested that the Appellants remove their equipment and “all hazardous and environmentally damaging material” from the Property. The Pueblo alleges that the Appellants are trespassing in violation of federal law.
The Pueblo is an indigenous Native American Tribe that was originally situated in Isleta [anglicized spelling], New Mexico, where from time to time it received population accretions from the Pueblos of Abu, Quari, and Grand Qui-vara. 1 In 1680, during the Pueblo Revolt, a portion of the Pueblo migrated south with retreating Spaniards and occupied camps in the present day El Paso vicinity. In 1682, Spanish Governor Otermin attempted to reconquer New Mexico, attacking the Isleta Pueblo, reducing it to his control and relocating it to the El Paso area with the Pueblo members who had *284 fled New Mexico in 1680. In 1682, the Pueblo was situated at its present site in what is now El Paso County, Texas.
In 1751, the Governor of New Mexico granted land, including the Property, to the Pueblo. Neither its legal title nor aboriginal right to the Property was ever terminated by the Kingdom of Spain, the Republic of Mexico, or the Republic of Texas, the successive governments claiming sovereignty over- the area including the Property prior to the United States. 2 In 1845, Texas was admitted to the Union, sparking the Mexican-American War, which ending in 1848 with the signing of the Treaty of Guadalupe Hidalgo. Article VIII of the treaty guaranteed the protection of the title held by Mexican citizens to land in the United States, and member’s of the Tribe were, at the time the treaty was signed, Mexican citizens.
The Pueblo contends that between 1846 and 1850, the federal government acknowledged the Tribe’s interest in its lands. Nonetheless, the State of Texas (the “State”), evidently claiming or believing it held title, relinquished the Tribe’s land, including the Property, to a municipality. The Property was at some later time conveyed back to the State, and the State is the current title holder of record. The Pueblo argues that the State’s action violated the Trade and Intercourse Act, referred to as the Indian Nonintercourse Act (the “NIA”). 3 It claims that because of the violation of the NIA, the State’s relinquishment of the Property and all subsequent conveyances are null and void, making Appellants’ continued occupation of the Property illegal.
Appellants filed a motion to dismiss under Federal Rule of Civil Procedure 12(b)(6). In the motion, they asserted that the suit is barred by the Eleventh Amendment to the United States Constitution. 4 In an order entered January 26, 1999, the district court denied the motion after concluding that “Congress clearly intended to abrogate the States’ Eleventh Amendment immunity when it enacted the Noninter-course Act and Congress has the power to do so under the Indian Commerce Clause.” 5
ANALYSIS
I.
This court has jurisdiction, under the collateral order doctrine, to entertain
*285
an appeal of the denial of a Federal Rule of Civil Procedure 12(b)(6) motion to dismiss based upon a claim of Eleventh Amendment sovereign immunity.
See Puerto Rico Aqueduct and Sewer Auth. v. Metcalf &
Eddy,
Inc.,
II.
We hold that the State of Texas enjoys immunity, under the Eleventh Amendment, from a suit instituted by an Indian Pueblo alleging a cause of action arising under the NIA, 25 U.S.C. § 177. The Eleventh Amendment constitutes an important limitation on federal authority to review allegedly illegal or unconstitutional actions of state governments and their officers. And yet, our federal system requires that we protect state autonomy while promoting state compliance with federal law. Consequently, several methods of circumventing the Eleventh Amendment’s prohibition against suing states in federal court have arisen. Under the Eleventh Amendment, a state enjoys immunity from a suit instituted in a federal court by an Indian tribe, 6 unless the state expressly waives its sovereign immunity, 7 its immunity is properly abrogated by Congress, 8 or the suit “falls within the exception ... recognized for certain suits seeking declaratory and injunctive relief against state officers in their individual capacities.” 9 The Eleventh Amendment’s applicability to this case turns on whether this is a suit against the State, and if so, whether Congress validly abrogated state sovereign immunity in the NIA or whether the Pueblo may proceed under the doctrine of Ex parte Young. 10 We hold that this is a suit against the State, that Congress did not abrogate state sovereign immunity in the NIA, and that the Pueblo may not proceed under the Ex parte Young doctrine.
III.
Fii'st, before we analyze the issue of congressional abrogation of state immunity, we must determine whether the instant suit is one against the State. Often, suits stating a cause of action under a particular statute name both the state and state officials, in their individual capacities. Under those circumstances, a plaintiff mounts an attack against the state by arguing that the statute at issue abrogates sovereign immunity. If the court finds valid abrogation, both prospective and retroactive relief are available against the state. If however, the particular statute has not properly abrogated state sovereign immunity, the plaintiff may nevertheless challenge the action of the state officials under the
Ex parte Young
doctrine, for
*286
prospective relief.
See, e.g., Seminole Tribe v. Florida,
In the instant case, the Pueblo has not expressly named the State of Texas or one of its agencies as a defendant, but rather only certain state officials. In
Pennhurst State School & Hospital v. Halderman,
There may be a question, however, whether a particular suit in fact is a suit against the State....
When the suit is brought only against state officials, a question arises as to whether that suit is a suit against the State itself. Although prior decisions of this Court have not been entirely consistent on this issue, certain principles are well established. The Eleventh Amendment bars a suit against state officials when the state is the real, substantial party in interest. Thus, [t]he general rule is that relief sought nominally against an officer is in fact against the sovereign if the decree would operate against the latter ...
The Court has recognized an important exception to this general rule: a suit challenging the constitutionality of a state officials’s action is not one against the State. This was the holding of Ex parte Young ....
Id.
at 101-102,
For purposes of addressing congressional abrogation of immunity, we recognize that the State is the true party of interest in this case, although it has not been expressly named as a defendant. The State is the real party of interest because the State holds record title to the Property, utilizes the Property as a maintenance facility, and the Pueblo is attempting to persuade us to declare that title null and void. For purposes of deciding whether the
Ex parte Young
doctrine is applicable in the instant case, we acknowledge that the state officials are named in their individual capacities.
See, e.g., Fitzpatrick v. Bitzer,
IV.
Having determined that this is a suit against the State, we now address the question of whether Congress validly abrogated state sovereign immunity in the NIA. We hold that Congress has not. To validly abrogate state sovereign immunity, Congress must “ ‘unequivocally express ... its intent to abrogate the immunity,’ ... and second, ... [it must act] ‘pursuant to a valid exercise of power.’ ”
Florida Prepaid Postsecondary Ed. Expense Bd. v. College Sav. Bank,
- U.S. -, -,
*287
Appellants argue that, under
Seminole Tribe,
Congress’ intent to abrogate state sovereign immunity must be unmistakably clear in the statute. The NIA, they argue is silent as to abrogation.
11
The Pueblo relies primarily on
County of Oneida v. Oneida Indian Nation,
Appellants respond that the Tribe’s reliance on Oneida II is misplaced. Oneida II, they argue, dealt with whether the NIA provides tribes a private cause of action, not with whether the statute waives sovereign immunity. The State of New York, they point out, was not even a party to the suit.
Contrary to the Tribe’s assertion, Oneida II does not imply a private cause of action for Indians under the NIA. Indeed, the Supreme Court specifically declined to reach that issue. 12 The text of the statute does appear, however, to apply to the states in its invalidation of any unauthorized transaction. Even assuming an implied private cause of action, however', the Tribe makes a fatal logical leap by concluding that a congressional intent to abrogate state sovereign immunity flows from the fact that an implied private cause of action exists under a statute applicable to states and private individuals. The leap is especially huge considering the historical relationship between the United States and the Indians. 13 The statute could easily be determined to provide tribes an implied private cause of action against any party other than a state while reserving for the United States a cause of action as fiduciary against any party, including a state. Seminole Tribe provides that:
Congress’ intent to abrogate the States’ immunity from suit must be obvious from a clear legislative statement ... [A] general authorization for suit in federal court is not the kind of unequivocal statutory language sufficient to abrogate the Eleventh Amendment .. . Congress may abrogate the States’ constitutionally secured immunity from suit in federal *288 court only by making its intention unmistakably clear in the language of the statute.
V.
In
Seminole Tribe,
the Supreme Court overruled its holding in
Pennsylvania v. Union Gas Co.,
Equally misplaced is the Tribe’s reliance on Congress’ power in Section 5 of the 14th Amendment. The NIA was originally passed in 1790; the second NIA was passed in 1793, and the language of that act was carried forward in several future acts concluding with an act in 1834.
See Oneida I,
It is nonsensical to rely on the Fourteenth Amendment to justify abrogation under a statute passed before its ratification. The Pueblo cites no authority for the pi'oposition that Congress, in passing the NIA, could abrogate state sovereign immunity under a power not yet granted to it.
VI.
The district court did not address whether this suit may proceed under the Ex parte Young doctrine. However, as we now find that the district court erred with respect to abrogation, it becomes necessary to decide if the Pueblo may proceed with its suit against the state officials under Ex parte Young. Generally speaking, the Eleventh Amendment allows suits against state officers, however, whether a state officer may be sued depends, largely, on the claim presented and the nature of the relief sought.
Appellants argue that this is an action to quiet title, citing
Idaho v. Coeur d'Alene,
Moreover, Appellants argue, the Tribe’s assertion that the relief it seeks is merely prospective has been rejected in
John G. And Marie Stella Kenedy Memorial
*289
Foundation v. Mauro,
Appellants distinguish the instant case from
Florida Dep’t of State v. Treasure Salvors,
The Pueblo relies on
Coeur d’Alene,
arguing that in that case the Supreme Court reaffirmed the doctrine of
Ex parte Young.
The Tribe maintains that the Supreme Court declined to apply the
Ex parte Young
doctrine in
Coeur d’Alene
because of the particular relief sought—a quiet title action seeking to divest the state of any regulatory power over the disputed property—and the type of real property at issue, submerged lands. According to the Pueblo, Justice O’Connor’s concurrence makes clear that in cases involving ordinary land, a distinction can be made between possession and title. Here, as in
United States v. Lee,
Appellants respond that Texas has special interests equal to those of Idaho in Coeur d’Alene. The land at issue here is located in a highly developed area, used for highway construction, maintenance and operation, and has many improvement that help facilitate the purposes which it serves. According to the Appellants, the State will be unable to properly carry out its sovereign responsibilities with regards to state roadways if it loses possession of the property. Appellants note that this case should not be viewed any differently than a case where plaintiffs seek to take possession of land upon which a state highway has been constructed.
In
Coeur d’Alene,
Justice O’Connor’s concurrence sets forth the controlling test with regard to
Ex parte Young
as whether “a plaintiff alleges an ongoing violation of federal law, and [whether] the relief sought is prospective rather than retrospective.”
Id.
at 294,
Justice O’Connor distinguished
United States v. Lee
and
Tindal v. Wesley
on the grounds that, in those cases, possession could be distinguished
from
title. “A court could find that the officials had no right to remain in possession, thus conveying all the incidents of ownership to the plaintiff, without formally divesting the state of its title.”
Id.
at 290,
*290 There are two main problems with the Tribe’s arguments. First, the Tribe has not sufficiently distinguished its own case from a quiet title action, and second, Coeur d’Alene did not vitiate Mauro. The Tribe asserts in its First Amended Complaint that “The Pueblo retains legal title to all lands described in the Relinquishment Acts, as well as the right to possess those lands over which it exercised aboriginal possession on December 29, 1845.” By seeking to eject Appellants, the Tribe is asking this court to determine that the State has no title to the Property because title rests in the Pueblo. Additionally, the Tribes’s argument that the State will retain sufficient regulatory control over the Property rings hollow. A judgment for the Tribe will significantly alter the State’s regulatory control over the Property because the Property will be considered part of an Indian reservation under federal control. Moreover, the State here, unlike Florida in Treasure Salvors, has a color-able claim to title: the Tribe was not federally recognized until the 1900’s, so there is a question whether it would have even retained legal title to land held by it when Texas became a state.
Justice O’Connor’s concurring opinion in
Coeur d’Alene
deals specifically with submerged lands and avoids the topic of other pieces of real property. Also, there is no rationale for denial of
Ex parte Young
treatment in that case that represents the views of a majority of the Court. The Tribe therefore incorrectly relies on a statement in Justice O’Connor’s concurrence to declare
Mauro,
a case involving real property in another context, vitiated. Justice O’Connor set other contexts aside when she stated, “Whatever distinction can be drawn between possession and ownership of real property in other contexts, ....”
Coeur d’Alene,
CONCLUSION
We hold that the State of Texas enjoys immunity, under the Eleventh Amendment, from a suit instituted by an Indian pueblo alleging a cause of action arising under the NIA. Accordingly, we find that the district court erred in denying the Appellants’ Rule 12(b)(6) motion to dismiss, and we therefore REVERSE and RENDER, dismissing this case on the grounds of state sovereign immunity.
Notes
. In summarizing the factual background of this case, we have relied, in large part, upon the Tribe's First Amended Complaint, filed November 25, 1997. The facts alleged in the First Amended Complaint, as they pertain to the historical origins of the Pueblo and relationship to the Property, remain undisputed.
. According to the Complaint, the Republic of Texas claimed land including the Property but never exercised government control over it.
. Congress enacted the NIA in 1790. The Act was amended and repassed in 1793, 1796, 1799, 1802, and 1834. It is now codified at 25 U.S.C. § 177 and provides:
No purchase, grant, lease, or other conveyance of lands, or of any title or claim thereto, from any Indian nation or tribe of Indians, shall be of any validity in law or equity, unless the same be made by treaty or convention entered into pursuant to the Constitution. Every person who, not being employed under the authority of the United Stales, attempts to negotiate such treaty or convention, directly or indirectly, or to treat with any such nation or tribe of Indians for title or purchase of any lands by them held or claimed, is liable to a penalty of $1,000. The agent of any State who may be present at any treaty held with Indians under the authority ol the United States, in the presence and with the approbation of the commissioner of the United States appointed to hold the same, may, however, propose to, and adjust with, the Indians the compensation to be made for their claim to lands within such State, which shall be extinguished by treaty.
. The Eleventh Amendment provides that “[tjhe Judicial power of the United States shall not be construed to extend to any suit in law or equity, commenced or prosecuted against one of the United States by Citizens of another States, or by Citizens or Subjects of any Foreign State.” U.S. Const., Amend. XI. In addition, in
Hans v. Louisiana,
. “The Congress shall have the Power ... To regulate Commerce with foreign Nations, and among the several States, and with Indian Tribes;....” U.S. Const. Art. I, § 8, cl. 3.
. Eleventh Amendment immunity is eifective against Indian tribes and their members.

Ex parte Young,
.Indeed, Appellants argue that the NIA is not applicable to the states at all, presumably even in a suit by the United States. The 1790 version of the NIA provided that "no sale of lands made by any . . . tribe . . . shall be valid to any person or persons, or to any state. ...”
Subsequent versions deleted the reference to person, persons, and states. The current version of the act provides that ”[n]o purchase, . . . shall be of any validity in law or equity....” Appellants assert that this change in language evinces Congress’ intent to exclude the states from application of the statute altogether. Appellants’ argument is without merit. See
Oneida Indian Nation v. County of Oneida,
. Oneida II dealt with the 1893 version of the NIA. In that case, the Supreme Court remarked:
LBoth lower courts found] that the Oneidas had the right to sue on two theories: first, a common-law right of action for unlawful possession; and second, an implied statutory cause of action under the Nonintercourse Act of 1793. We need not reach the latter question as we think the Indians’ common-law right to sue is firmly established.
.
See, e.g., Montana v. United States,
. It appears from the opinion that the land, which was sometimes covered by the Laguna Madre, may have been characterized as submerged lands.
. Justice O'Connor states:
"Whatever distinction can be drawn between possession and ownership of real property in other contexts, it is not possible to make such a distinction for submerged lands ... In my view, because a ruling in the Tribe's favor, in practical effect, would *290 be indistinguishable from an order granting the Tribe title to submerged lands, they Young exception to the Eleventh Amend-merit's bar is not properly invoked here.'
