Question: When did the territory that the marble for the Lincoln memorial came from become part of the United States?

full_context: Document 1: Montana: Under Territorial Governor Thomas Meagher, Montanans held a constitutional convention in 1866 in a failed bid for statehood. A second constitutional convention was held in Helena in 1884 that produced a constitution ratified 3:1 by Montana citizens in November 1884. For political reasons, Congress did not approve Montana statehood until 1889. Congress approved Montana statehood in February 1889 and President Grover Cleveland signed an omnibus bill granting statehood to Montana, North Dakota, South Dakota and Washington once the appropriate state constitutions were crafted. In July 1889, Montanans convened their third constitutional convention and produced a constitution acceptable by the people and the federal government. On November 8, 1889 President Benjamin Harrison proclaimed Montana the forty-first state in the union. The first state governor was Joseph K. Toole. In the 1880s, Helena (the current state capital) had more millionaires per capita than any other United States city.
Document 2: Washington Monument: The interior is occupied by iron stairs that spiral up the walls, with an elevator in the center, both supported by eight iron columns, which do not support the stone structure. The stairs contain fifty sections, most on the north and south walls, with many long landings stretching between them along the east and west walls. These landings allowed many inscribed memorial stones of various materials and sizes to be easily viewed while the stairs were accessible (until 1976), plus one memorial stone between stairs that is difficult to view. The pyramidion has eight observation windows, two per side, and eight red aircraft warning lights, two per side. Two aluminum lightning rods connected via the elevator support columns to ground water protect the monument. The monument's present foundation is 37 feet (11.3 m) thick, consisting of half of its original bluestone gneiss rubble encased in concrete. At the northeast corner of the foundation, 21 feet (6.4 m) below ground, is the marble cornerstone, including a zinc case filled with memorabilia. Fifty American flags fly 24 hours a day on a large circle of flag poles centered on the monument. In 2001, a temporary screening facility was added to the entrance to prevent a terrorist attack. In 2011, an earthquake slightly damaged the monument, mostly the pyramidion.
Document 3: History of Colorado: The United States Congress passed an enabling act on March 3, 1875, specifying the requirements for the Territory of Colorado to become a state. On August 1, 1876 (28 days after the Centennial of the United States), U.S. President Ulysses S. Grant signed a proclamation admitting the state of Colorado to the Union as the 38th state and earning it the moniker ``Centennial State ''. The borders of the new state coincided with the borders established for the Colorado Territory.
Document 4: Lincoln Memorial: The exterior of the Memorial echoes a classic Greek temple and features Yule marble from Colorado. The structure measures 189.7 by 118.5 feet (57.8 by 36.1 m) and is 99 feet (30 m) tall. It is surrounded by a peristyle of 36 fluted Doric columns, one for each of the 36 states in the Union at the time of Lincoln's death, and two columns in - antis at the entrance behind the colonnade. The columns stand 44 feet (13 m) tall with a base diameter of 7.5 feet (2.3 m). Each column is built from 12 drums including the capital. The columns, like the exterior walls and facades, are inclined slightly toward the building's interior. This is to compensate for perspective distortions which would otherwise make the memorial appear to bulge out at the top when compared with the bottom, a common feature of Ancient Greek architecture.
Document 5: Lincoln Memorial: Lying between the north and south chambers is the central hall containing the solitary figure of Lincoln sitting in contemplation. The statue was carved by the Piccirilli Brothers under the supervision of the sculptor, Daniel Chester French, and took four years to complete. The statue, originally intended to be only 10 feet (3.0 m) tall, was, on further consideration, enlarged so that it finally stood 19 feet (5.8 m) tall from head to foot, the scale being such that if Lincoln were standing, he would be 28 feet (8.5 m) tall. The widest span of the statue corresponds to its height. Of Georgia white marble, it weighs 175 short tons (159 t) and was shipped in twenty - eight pieces.
Document 6: El Dorado Confederate Monument: The El Dorado Confederate Monument is located on the grounds of the Union County Courthouse in El Dorado, Arkansas, near the corner of North Main and South Washington Streets. It consists of a statue of a Confederate Army soldier in mid-stride, mounted on top of a temple-like structure supported by four cannon-shaped Ionic columns. The columns support a lintel structure bearing inscriptions on three sides, above which is a tiered roof with cannonballs at the corners. The temple structure is high, and square; the statue measures by by . Both the statue and the temple are constructed of gray/blue striated marble. Inside the temple structure is a water fountain that no longer works.
Document 7: St. Peter's Basilica: The facade designed by Maderno, is 114.69 metres (376.3 ft) wide and 45.55 metres (149.4 ft) high and is built of travertine stone, with a giant order of Corinthian columns and a central pediment rising in front of a tall attic surmounted by thirteen statues: Christ flanked by eleven of the Apostles (except Saint Peter, whose statue is left of the stairs) and John the Baptist. The inscription below the cornice on the 1 metre (3.3 ft) tall frieze reads:
Document 8: Lincoln Memorial Reflecting Pool: The Lincoln Memorial Reflecting Pool was designed by Henry Bacon, and was constructed in 1922 and 1923, following the dedication of the Lincoln Memorial. It is approximately 2,029 feet (618 m) long (over a third of a mile) and 167 feet (51 m) wide. The perimeter of the pool is therefore 4,392 feet (1,339 m), about 0.83 miles around. It has a depth of approximately 18 inches (46 cm) on the sides and 30 inches (76 cm) in the center. It holds approximately 6,750,000 U.S. gallons (25,500,000 L) of water.

Document 10: Utah Territory: The Territory of Utah was an organized incorporated territory of the United States that existed from September 9, 1850, until January 4, 1896, when the final extent of the territory was admitted to the Union as the State of Utah, the 45th state.
Document 11: Colorado Territory: The movement to create a territory within the present boundaries of Colorado followed nearly immediately. Citizens of Denver and Golden pushed for territorial status of the newly settled region within a year of the founding of the towns. The movement was promoted by William Byers, publisher of the Rocky Mountain News, and by Larimer, who aspired to be the first territorial governor. In 1859, settlers established the Territory of Jefferson, and held elections, but the United States Congress did not recognize the territory, and it never gained legal status.
Document 12: Ohio: On February 19, 1803, U.S. President Thomas Jefferson signed an act of Congress that approved Ohio's boundaries and constitution. However, Congress had never passed a resolution formally admitting Ohio as the 17th state. The current custom of Congress declaring an official date of statehood did not begin until 1812, with Louisiana's admission as the 18th state. Although no formal resolution of admission was required, when the oversight was discovered in 1953, Ohio congressman George H. Bender introduced a bill in Congress to admit Ohio to the Union retroactive to March 1, 1803, the date on which the Ohio General Assembly first convened. At a special session at the old state capital in Chillicothe, the Ohio state legislature approved a new petition for statehood that was delivered to Washington, D.C. on horseback. On August 7, 1953 (the year of Ohio's 150th anniversary), President Eisenhower signed a congressional joint resolution that officially declared March 1, 1803, the date of Ohio's admittance into the Union.

Document 14: Lincoln Memorial: With Congressional approval and a $300,000 allocation, the project got underway. On February 12, 1914, a dedication ceremony was conducted and the following month the actual construction began. Work progressed steadily according to schedule. Some changes were made to the plan. The statue of Lincoln, originally designed to be 10 feet (3.0 m) tall, was enlarged to 19 feet (5.8 m) to prevent it from being overwhelmed by the huge chamber. As late as 1920, the decision was made to substitute an open portal for the bronze and glass grille which was to have guarded the entrance. Despite these changes, the Memorial was finished on schedule. Commission president William H. Taft -- who was then Chief Justice of the United States -- dedicated the Memorial on May 30, 1922 and presented it to President Warren G. Harding, who accepted it on behalf of the American people. Lincoln's only surviving son, 78 - year - old Robert Todd Lincoln, was in attendance.
Document 15: Colorado Territory: Colorado Territory was officially organized by Act of Congress on February 28, 1861, out of lands previously part of the Kansas, Nebraska, Utah, and New Mexico territories. Technically the territory was open to slavery under the Dred Scott Decision of 1857, but the question was rendered moot by the impending American Civil War and the majority pro-Union sentiment in the territory. The name "Colorado" was chosen for the territory. It had been previously suggested in 1850 by Senator Henry S. Foote as a name for a state to have been created out of present-day California south of 35° 45'. To the dismay of Denverites, the town of Colorado City was designated the first territorial capital, quickly succeeded by Golden. Denver eventually became the temporary territorial capital, but was not designated the permanent capital until 1881, five years after Colorado became a state.
