delivered the opinion of the court.
The eight thousand plaintiffs in this case are members of the Choctaw and Chickasaw tribes. Each of them holds a patent to 320 acres of allotted land issued under the terms of the' Curtis Act (June 28, 1898, 30 Stat. 495, 507, c. 517), which contained a provision “that the land should be non-taxable” for a limited time. Before the expiration of that period the officers of the State of Oklahoma in- . stituted proceedings with a view of assessing and collecting taxes on these lands lying within that State. The plaintiffs' application for an injunction was denied.
In order to understand the issues presented by the writ of error it is necessary to refer, as briefly as possible, to certain well-known facts, and to material portions of lengthy statutes, under which the tribal property of the Choctaws and Chickasaws was divided in severalty among their members.
The Five Civilized Tribes owned immense tracts of land in territory that is now embraced within the limits of the State of Oklahoma. The legal title was in the Tribes for the common use of their members. But the fact that so extensive an area was held under a system that did not recognize private property in land, presented a serious obstacle to the creation of the State which Congress desired to organize for the government and development of that part of the country. And, with a view of removing these difficulties, it provided (March 3, 1893, 27 Stat. 612, 645, c. 209) for the appointment of the Dawes Commission, authorizing it to enter into negotiations with these Tribes for the extinguishment of their title, either by cession to the United States or by allotment, in severalty, among their members. As might have been anticipated, the Commission found that many of the Indians were greatly opposed to any change. “Some of them held passionately to their institutions from custom *668 and patriotism, and others held with equal tenacity because of the advantages and privileges they enjoyed.” (20 H. R. Doc., 1903-4, p. 1.) After several years of negotiations their opposition was so far overcome that provisional agreements were made which contemplated most radical changes in the' political and property rights of the Indians.
On April 23, 1897, the Dawes Commission and the Choctaw and Chickasaw representatives made what is known as the Atoka Agreement. It was incorporated bodily into the Curtis Act of June 28,1898 (30 Stat. 505), and was modified by the act of July 1, 1902 (32 Stat. 641, 657, c. 1362).
. These two acts, containing what is known as the Atoka Agreement and the Supplemental Agreement, provided that Indian laws and courts should be at once abolished; that there should be an enrollment of all the members of the tribe; and that the members of the two tribes should become citizens of the United States.
It was also provided, as appears from extracts copied in the margin, 1 that, each member of the tribe should have *669 allotted to bim his share of the land — all of which "shall be non-taxable while the title remains in the original allottee;” that a part of the land could be sold after one year and all of it sold after five years; that the patents issued to the allottee "should be framed in. conformity with the provisions of the Agreement,”- and that the acceptance of such patent should be operative as an assent on his part to the allotment of all land of the tribes in accordance with the provisions of the Agreement, and as a relinquishment of all his interest in other parts of the common property.
The complaint does not state when the plaintiffs received their patents, but the report of the Dawes Corn- *670 mission for the year ending June 1, 1904 (20 H. R. Doc., 27-42), shows that the enrollment and allotment had so far progressed as to make it fair to assume that most, if not all, of the patents had been issued, and that much of the land was alienable and all of it was non-'taxable when, on November 16, 1907, Oklahoma was admitted into the Union. The constitution of that State provided that all existing rights should continue as if no change in government had taken place, and that property- exempt from taxation by virtue of treaties and Federal laws should so remain during the force and effect of such treaties or Federal laws.
No taxes were assessed against the lands of the plaintiffs for the year 1907, but on May 27, 1908 (35 Stat. 312, c. 199), Congress passed a general act removing restrictions from the sale and encumbrance of land held by Indians of the class to which the plaintiffs belong. .Another section provided that lands from which restrictions had been removed should be subject to taxation.
Thereupon proceedings were instituted by the State of Oklahoma with a view of assessing the plaintiffs’ lands for taxes. This they sought to enjoin, but their complaint was dismissed on demurrer. The case was carried to the Supreme Court of the State which held that Oklahoma was not a party to any contract with the Indians; that the United States, by virtue of its governmental power over the Indians, could have substituted title in severalty for ownership in common without plaintiffs’ consent and that, for want of a consideration, the provision that the-land should be non-taxable was not a contract, but a mere gratuity which could be withdrawn at will. The court thereupon overruled plaintiffs’ contention that they had a vested right of exemption which prevented the State from taxing the land at this time and dismissed their suit.
1. There are many cases, some of which are cited in the opinion of the Supreme Court of Oklahoma
(Thomas
v.
*671
Gay,
This sovereign and plenary power was exercised and retained in all the dealings and legislation under which the lands of the Choctaws and Chickasaws were divided in severalty among the members of the Tribes. For, although the Atoka Agreement is in the form of a contract it is still an integral part of the Curtis Act, and, if not a treaty, is a public law relating to tribal property, and as such was amendable and repealable at the will of Congress. But there is a broad distinction between tribal property and private property, and between the power to abrogate a statute and the authority to destroy rights acquired under such law.

Felps,
2. The individual Indian had no title or enforcible right in the tribal property. But as one of those entitled to occupy the land he did have an equitable interest, which Congress recognized and which it desired-to have satisfied and extinguished. The Curtis Act was framed with a view of having every such claim satisfactorily settled. And though.it provided for a division of the land in severalty, it offered a patent of non-taxable land only to those who would relinquish their claim in the other property of the Tribe formerly held for their common use. For, the Atoka Agreement, after declaring that “all land *672 allotted should be non-taxable,” stipulated further that each enrolled member of the Tribes should receive a patent framed in conformity with the Agreement, and that each Choctaw and Chickasaw who accepted such patent should be held thereby to assent to the terms of this Agreement and to relinquish all of his right in the property formerly held in common.
There was here, then, an offer of non-taxable land. Acceptance by the party to whom the offer was made, with the consequent relinquishment of all claim to other lands furnished a part of the consideration, if, indeed, any was needed, in such a case, to support either the grant or the exemption.
Wisconsin &c. R. R.
v.
Powers,
As the plaintiffs were offered the allotments on the conditions proposed; as they accepted the terms and, in the relinquishment of their claim, furnished a consideration which was sufficient to entitle them to enforce whatever rights were conferred, we are brought to a consideration of the question as to what those rights were.
3. On the part of the State it is argued that there was, in fact, no tax exemption, but that that provision was only intended to guard absolutely, against alienation of the land, whether for taxes, or at judicial sale, or by private contract. In other words, it is said that the tax exemption was only an additional prohibition against a sale, so that when the restrictions against alienation were removed by the act of 1908 (35 Stat. 312), the provision as to nontaxability went as a necessary part thereof.
*673
But the exemption and non-alienability were two separate and distinct subjects. One conferred a right and the other imposed a limitation. The defendant’s argument also ignores the fact that, in this case, though the land could be sold after five years it might remain nontaxable for 16 years longer, if the Indian retained title during that length of time. Restrictions on alienation were removed by lapse of time. He could sell part after one year, a part after three years and all except homestead after five years. The period of exemption was not co-incident with this five-year limitation. On the contrary the privilege of non-taxability might last for 21 years, thus recognizing that the two subjects related to different periods and that neither was dependent on the other. The right to remove the restriction was in pursuance of the power under which Congress could legislate as to the status of the ward and lengthen, or shorten the period of disability. But the provision that the land should be non-taxable was a property right, which Congress undoubtedly had the power to grant. That right fully vested in the Indians and was binding upon Oklahoma.

4. The record contains no copy of any of the patents under which the plaintiffs hold. But the act provided that they should be framed in conformity with the Atoka Agreement. Those who signed the patent could not convey more rights than were granted by that part of the Curtis Act, nor could they, by omission, deprive the patentee of any exemption to which he was thereby entitled. The patent and the legislation of Congress must be construed together, and when so construed they show that Congress, in consideration of the Indians’ relinquishment of all claim to the common property, and for other satisfactory reasons, made a grant of land which should be non-taxable for a limited period. The patent issued in *674 pursuance of those statutes gave the Indian as good a title to the exemption as it did to the land itself. Under the provisions of the Fifth Amendment there was no more power to deprive him of the exemption than of any other right in the property. No statute would have been valid which reduced his fee to a life estate, or attempted to take from him ten acres, or fifty acres, or the timber growing on the land. After he accepted the patent the Indian could not be heard, either at law or in equity, to assert any claim to the common property. If he is bound, so is the tribe and the Government when the patent was issued.
5. It is conceded that no right which was actually conferred on the Indians can be arbitrarily abrogated by statute. But as it is claimed that he, in fact, acquired no valid exemption, since it stands on a different footing from the grant of the land itself; and that, though the provision of non-taxability added to the value of the property, it can be withdrawn because, if not a gratuity, it is at least subject to the general rule that tax exemptions are to be strictly construed and are subject to repeal unless the contrary clearly appears.

Cook,
6. But in the Government’s dealings with the Indians the rule is exactly the contrary. The construction, instead of being strict, is liberal; doubtful expressions, instead of being resolved in favor of the United States, are to be resolved in favor of a weak and defenseless people, who are wards of the nation, and dependent wholly upon its protection and good faith. This rule of construction has been recognized, without exception, for more than a hundred years and has been applied in tax cases.
For example, in
Kansas Indians,
The provision that “all land shall be non-taxable” naturally indicates that the exemption is attached to the *676 land — only an artificial rule can make it a personal privilege. But if there is any conflict between the natural meaning and the technical construction, — if there were room for doubt, or if there were any question as to whether this was a personal privilege and repealable, or an incident attached to the land itself for a limited period, that doubt, under this rule, must be resolved in favor of the patentee.

7. There have been comparatively few cases which discuss the legislative power over private property held by the Indians. But those few all recognize that he is not excepted from the protection guaranteed by the Constitution. His private rights are secured and enforced to the same extent and in the same way as other residents or citizens of the United States.
In re Heff,
Nothing that was said in
Tiger
v.
Western Investment Co.,
But there was no intimation that the power of wardship-conferred authority on Congress to lessen any of the rights of property which had been vested in the individual Indian by prior laws or contracts. Such rights are protected from repeal by the provisions of the Fifth Amendment.
The constitution of the State of Oklahoma itself expressly recognizes that the exemption here granted must be protected until it is lawfully destroyed. We have seen that it was a 'vested property right which could not be *679 abrogated by statute. The decree refusing to enjoin the assessment of taxes on the exempt lands of plaintiffs must therefore be reversed, and the case remanded for further proceedings not inconsistent with this opinion.
