Question: What other name is the Act from which tribes has been previously exempt under the The Curtis Act of 1898 known as?

Context paragraphs:
Council Tax: Council Tax is a local taxation system used in England, Scotland and Wales.  It is a tax on domestic property which was introduced in 1993 by the Local Government Finance Act 1992, replacing the Community Charge (popularly known as the Poll Tax).  Each property is assigned one of eight bands (A to H) based on property value, and the tax is set as a fixed amount for each band.  Some property is exempt from the tax, some people are exempt from the tax, while some get a discount.

Curtis Act of 1898: The Curtis Act of 1898 was an amendment to the United States Dawes Act; it resulted in the break-up of tribal governments and communal lands in Indian Territory (now Oklahoma) of the Five Civilized Tribes of Indian Territory: the Choctaw, Chickasaw, Muscogee (Creek), Cherokee, and Seminole.  These tribes had been previously exempt from the 1887 General Allotment Act (Dawes Act) because of the terms of their treaties.  In total, the tribes immediately lost control of about 90 million acres of their communal lands; they lost more in subsequent years.

Oklahoma Organic Act: An Organic Act is a generic name for a statute used by the United States Congress to describe a territory, in anticipation of being admitted to the Union as a state.  Because of Oklahoma's unique history, (much of the state was a place where aboriginal natives have always lived and after forced removal many other tribes were relocated here), an explanation of the Oklahoma Organic Act needs a historic perspective.  In general, the Oklahoma Organic Act may be viewed as one of a series of legislative acts, from the time of Reconstruction, enacted by Congress in preparation for the creation of a unified State of Oklahoma.  The Organic Act created Oklahoma Territory, and Indian Territory that were Organized incorporated territories of the United States out of the old "unorganized" Indian Territory.  The Oklahoma Organic Act was one of several acts whose intent was the assimilation of the tribes in Oklahoma and Indian Territories through the elimination of tribal reservations and the elimination of the tribes' communal ownership of property.

Dawes Act: The Dawes Act of 1887 (also known as the General Allotment Act or the Dawes Severalty Act of 1887),

Sligo Corporation election, 1919: An election for all 24 members of Sligo Corporation took place on 15 January 1919, using the single transferable vote (STV).  Urban districts in Ireland held annual elections on 15 January each year under the Local Government (Ireland) Act 1898, using plurality voting to replace a cohort of one-third or one-quarter of their councillors.  Those elections for 1915–19 were postponed while the First World War was still in progress.  The Sligo election was held under the Sligo Corporation Act of 1918, a private act passed in the UK Parliament under the sponsorship of the Sligo Ratepayers Association (SRA), an alliance of Protestants and businessmen which opposed the actions of the outgoing corporation.  The election under the 1918 act was exempt from the general postponement.  In the 1919 election, the SRA ran a slate of 18 candidates, 11 Protestant and 7 Catholic, and won 8 seats; Sinn Féin, Labour, and an Independent Nationalist had a majority of 13 seats between them.  It was the second STV election ever in Ireland; the first was in the University of Dublin in the November 1918 Westminster election.  The outcome was seen as a vindication of STV, which was adopted for all Irish local authorities by the Local Government (Ireland) Act 1919, in time for the 1920 local elections.  The 1918 act envisaged triennial elections in Sligo, as the 1919 act did throughout Ireland.  In the event, the Irish War of Independence, Irish Civil War, and aftermath meant the next local elections were postponed until 1925.

Daehan Gyenyeonsa: The "Daehan Gyenyeonsa" (A History of the Final Years of the Empire of Great Han of Korea) is, as the title indicates, a history of the final forty years of Korea's Joseon dynasty (after 1898 known as the Empire of Great Han).  It was penned by a minor government official and member of the Korean enlightenment movement, Jeong Gyo (鄭喬 1856-1925), about whom little is known.  The books is chronologically ordered and much of the historical content is based upon Jeong's own experiences and eye-witness accounts, yielding up rich historical detail and anecdote not available elsewhere.  It is particularly useful in its details of Korea's Independence Club.

Atoka Agreement: The Atoka Agreement is a document signed by representatives of the Choctaw and Chickasaw Indian Nations and members of the United States Dawes Commission on April 23, 1897 at Atoka, Indian Territory (now Oklahoma).  It provided for the allotment of communal tribal lands of the Choctaw and Chickasaw nations in the Indian Territory to individual households of members of the tribes, who were certified as citizens of the tribes.  Land in excess of the allotments could be sold to non-natives.  Provisions of this agreement were later incorporated into the Curtis Act of 1898, which provided for widespread allotment of communal tribal lands.

Denotified Tribes: Denotified Tribes (DNTs), also known as Vimukta Jati, are the tribes that were originally listed under the Criminal Tribes Act of 1871, as "Criminal Tribes" and "addicted to the systematic commission of non-bailable offences."  Once a tribe became "notified" as criminal, all its members were required to register with the local magistrate, failing which they would be charged with a "crime" under the Indian Penal Code.  The Criminal Tribes Act of 1952 repealed the notification, i.e. 'de-notified' the tribal communities.  This Act, however, was replaced by a series of Habitual Offenders Acts, that asked police to investigate a "suspect's" "criminal tendencies" and whether their occupation is "conducive to settled way of life."  The denotified tribes were reclassified as "habitual offenders" in 1959.

Endowment tax: Endowment tax is a proposed US taxation of endowments.  The proposers believe that certain institutions are taking advantage of the endowment systems tax free status when their non-profit status is questionable.  The city of Cambridge, Massachusetts, has proposed taxing MIT and other major universities on these previously exempt, non-profit earnings.

State of Sequoyah: The State of Sequoyah was a proposed state to be established from the Indian Territory in the eastern part of present-day Oklahoma.  In 1905, with the end of tribal governments looming (as prescribed by the Curtis Act of 1898), Native Americans of the Five Civilized Tribes—the Cherokee, Chickasaw, Choctaw, Creek (Muscogee), and Seminole—in Indian Territory proposed to create a state as a means to retain control of their lands.  Their intention was to have a state under Native American constitution and governance.  The proposed state was to be named in honor of Sequoyah, the Cherokee who created a writing system in 1825 for the Cherokee language.
