OPINION
Cаry Harden-Bey, an incarcerated pro se litigant, challenges the dismissal under *791 § 1997e(c) of the Prison Litigation Reform Act of 1995, 42 U.S.C. § 1997e(c), of his § 1983 claims against several employees of the Michigan Department of Corrections. Because Harden-Bey has stated a cognizable due-process claim, we reverse that part of the district court’s order. And because he has failed to state a cognizable cruel- and-unusual-punishment claim under the Eighth (and Fourteenth) Amendment or a cognizable equal-protection claim under the Fourteenth Amendment, we affirm the remaining parts of the district court’s order.
I.
Harden-Bey is an inmate at the Alger Maximum Correctional Facility, which is located in Munising, Michigan, and which contains six housing units — three for the general inmate population and three for inmates committed to administrative segregation. On September 18, 2002, prison officials placed Harden-Bey in administrative segregation because “[rjeports have been received from prisoners and staff that ... Harden-Bey is using his position as a ranking member of the Moori[s]h Science Temple of America to direct аnd influence his follo[wers] to strong arm other prisoners, col[l]ect debts, approve prisoner assaults and is involved in the approval and planning of a major serious assault on staff and [a] takeover of the housing unit and/or facility here at [Alger]. Based upon these reports, prisoner Harden-Bey is considered to be a threat to the safety and security of this facility.” (emphasis omitted). Harden-Bey requested a hearing, an investigation and access to all relevant witnesses and documents, claiming that prison officials premised their decision to segregate him on false and religiously biased information.
After conducting a hearing on the matter, a prison official upheld Harden-Bey’s placement in administrative segregаtion. The Hearings Division denied his request for a rehearing, after which he filed an internal grievance challenging his confinement in administrative segregation. In January 2003, prison officials denied the grievance because Harden-Bey had “clearly demonstrated that [he was] a serious threat to the physical safety of prisoners/staff.” He filed additional internal grievancеs in 2004 and 2005 related to his administrative segregation, alleging that several prison officials used their authority and influence to subject him to continued and “indefinite” confinement in administrative segregation and denied him periodic reviews for release from segregation. Prison officials rejected each grievance.
In December 2005, Harden-Bey filed this § 1983 action against several prison officials, challenging his placement and continued confinement in administrative segregation on several federal constitutional grounds. After granting Harden-Bey leave to proceed in forma pauperis, the district court dismissed the complaint for failure to state a claim upon which relief may be granted. See 28 U.S.C. § 1915(e)(2)(B)(ii); 42 U.S.C. § 1997e(c).

A.
In challenging the district court’s rejection of his due-process claim at the pleading stage, Harden-Bey focuses on the “long term indefinite” nature of his placement in administrative segregation and the absence of hearings during it. In one sense, he faces a steep climb. The Due Process Clause does not protect every administrative slight that occurs behind prison walls. It requires process only whеn a “life, liberty, or property” interest is at stake. U.S. Const, amend. XIV, § 1. And when it comes to the principal objection to *792 confinement in a prison cell, the deprivation of “liberty,” the State already has given Harden-Bey the procedural protections to which he is entitled: a trial in compliance with the due process and other constitutional guarantees аpplicable to crime and punishment.
But in another sense, Harden-Bey has a point. Even after a proper conviction and sentence, an inmate still retains a “liberty” interest, guarded by due process, with respect to state-imposed prison discipline that rises to the level of an “atypical and significant hardship on the inmate.”
Sandin v. Conner,
The question here is whether Harden-Bey’s allegedly indefinite confinement in administrative segregation, three years and running as of the time of the complaint, amounts to an “atypical and significant hardship on [him] in relation to the ordinary incidents of prison life.”
Sandin,
Two Supreme Court cases cast considerable light on the answer to this question.
Sandin
addressed whether an inmate’s placement in disciplinary segregation for 30 days presented the type of atypical, significant deprivation that implicated a protected liberty interest.
Austin
addressed whether inmates’ assignment to a maximum-security prison with “highly restrictive conditions” implicates a liberty interest.
In deciding whether changes to an inmate’s conditions of confinement implicate a cognizable liberty interest, both
Sandin
and
Austin
considered the nature of the more-restrictive confinement
and
its duration in relation to prison norms and to the terms of the individual’s sentence. In
*793
Sandin,
a 30-day placement in disciplinary segregation did not suffice to implicate a protected liberty interest; in
Austin,
an “indefinite” placement in a maximum-security prison faсility with “highly restrictive conditions” (together with other features of the transfer) sufficed to implicate such an interest,
id.
at 213, 224,
Consistent with these decisions, most (if not all) of our sister circuits have considered the nature of the more-restrictive confinement
and
its duration in determining whether it imposes an “atypical and significant hardship.”
See, e.g., Iqbal v. Hasty,
As Sandin and Austin indicate and as the cases from our sister circuits suggest, the duration of prison discipline bears on whether a cognizable liberty interest exists. Harden-Bey has been in administrative segregation for three yеars. He alleges, not improbably, that his placement remains “indefinite” and, what is more, that prison officials refuse to give him a hearing to explain his continued detention. While the prison may have ample reasons for segregating Harden-Bey from the general prison population and may indeed have given him all of the procedural protections to which he is entitled before and after this placement, we have no way of knowing whether that is so based solely on his complaint. On this bare-bones record, we hold only that the district court erred in dismissing the complaint on the ground that the duration of this prison discipline, three years and counting, does not affect whether Harden-Bey has a protected liberty interest. On remand, the court should consider whether the nature of this placement in administrative segregation together with its duration creates a cognizable liberty interest and, if so, whether the State has given Harden-Bey the protection to which he is due.
That would end the matter but for one complication. The district court, it turns out, had a reasonable basis for thinking that the duration of prison disсipline has
*794
little or no bearing on whether it is “atypical and significant.” In one published opinion and in some unpublished opinions and orders, we have said that “administrative segregations [do] not ... involve an ‘atypical and significant’ hardship implicating a protected liberty interest
without regard to duration.” Jones v. Baker,
Yet this language
from Jones
does not deserve the credence that the district court and some of our unpublished deсisions have given it. At issue in
Jones
was prison discipline imposed on an inmate who participated in the 1993 prison riots at the Southern Ohio Correctional Facility and who was implicated in the murder of a prison officer. The question at hand was whether the inmate’s segregation during the two and one-half years between the riots and an administrative hearing regarding his role in the murder violаted due process.
But two other features of Jones limit its application here. One: Jones itself confined the reach of its decision, noting “that our holding here does not mean that every administrative segregation regardless of length or the reason for the segregation will not implicate a liberty interest. The facts of this case and the extraordinarily good reasons for holding plaintiff in segregation form the basis for this decision.” Id. at 813. Two: Jones involved the review of a summary judgment decision, not the review of a pleading-stage dismissal. The panel’s holding thus turned not just on whether the placement implicated a protected liberty interest but also on whether the State’s explanation — that it neеded to segregate an inmate implicated in the murder of a prison guard during the ensuing two-and-a-half-year investigation — sufficed to establish as a matter of law that no due process violation occurred.
Jones does not control this case. Harden-Bey has already been in administrative segregation for three years, not two and a half, and his confinement is “indefinite,” not limitеd until a scheduled hearing. And in view of the pleading-stage dismissal of this case, we do not know the particulars of the State’s explanation for its confinement of Harden-Bey or the frequency with which hearings are given to determine whether he should remain in administrative segregation. Most fundamentally, however, Jones cannot stand for what amount to two irreconcilable propositions: (1) that administrative segregation never implicates a protected liberty interest “without regard to duration,” id. at 812, and (2) that this does not mean “every administrative segregation regardless of length ... will not implicate a liberty interest,” id. at 813. In the end, Jones, like all decisions, stands for no more and no less than what was necessary to resolve the case — that the State’s explanation for holding the inmate in administrative segregation for two and a half years sufficed as a matter of law to establish that no due process violation occurred.
Our other published decisions in this area do not require a different approach. They deal with the distinct question whether an initial placement in administrative segregation is “atypical and significant” or whether a placement for a relatively brief period of time is “atypical and significant.”
See Harbin-Bey v. Rutter,
In the final analysis, the nature and duration of an inmate’s segregation may affect whethеr the State has implicated a liberty interest that warrants due-process protection—as do the other Sandin factors, such as whether the segregation will affect the overall duration of the inmate’s sentence. Because the district court dismissed this case at the pleading stage based in part on the conclusion that the duration of the segregation has littlе or no bearing on whether that segregation was atypical and significant, we reverse that decision and remand the case so that the district court can assess in the first instance whether the nature and allegedly “indefinite” duration of Harden-Bey’s segregation makes these conditions “atypical and significant in relation to the ordinary incidents of prison life.”
B.
The district сourt correctly rejected Harden-Bey’s Eighth Amendment claim. To move beyond the pleading stage in this setting, an inmate must allege that he has been deprived “of the minimal civilized measure of life’s necessities.”
Rhodes v. Chapman,
In his complaint, Harden-Bey makes no allegations that rise to the level of an Eighth Amendment violation. “Because placement in segregation is a routine discomfort that is a part of the penalty that criminal offenders pay for their offenses against society, it is insufficient to support an Eighth Amendment Claim.”
Murray v. Unknown Evert,
C.
Harden-Bey’s equal-protection claim also fails as a matter of law. As the district court correctly pointed out, this aspect of the complaint says only that his placement in administrative segregation was “created on Religious Bias.” “[I]n the context of a civil rights claim, ... conclusory allegations of unconstitutional conduct without specific factual allegations fail to state a claim.”
Lillard v. Shelby County Bd. of Educ.,
Even if Harden-Bey means to rest his claim on the allegation that the prison placed him in administrative segregation because he “is using his position as a ranking member of the Moori[s]h Science Temple of America” to cause disturbances in the prison, that does not help him. His complaint alleges no facts to contradict the disciplinary record, which shows that prison officials placed him in administrative segregation because of past (and impending) efforts to cause disturbances within the prison, not because of his religion.

For these reasons, we affirm in part, reverse in part and remand the case to the district court to consider Harden-Bey’s due-process claim in the first instance.
