full_context: Document 1: Dakota Territory: The Territory of Dakota was an organized incorporated territory of the United States that existed from March 2, 1861, until November 2, 1889, when the final extent of the reduced territory was split and admitted to the Union as the states of North and South Dakota.
Document 2: New Mexico: Inhabited by Native Americans for thousands of years before European exploration, it was colonized by the Spanish in 1598 as part of the Imperial Spanish viceroyalty of New Spain. In 1563, it was named Nuevo México after the Aztec Valley of Mexico by Spanish settlers, 223 years before the establishment and naming of the present - day country of Mexico; thus, the present - day state of New Mexico was not named after the country today known as Mexico. Its geographic characteristics made settlement and effective political control difficult which prompted Mexico's invasion and control of the area from 1824 to 1846. New Mexico's Spanish origins made cultural integration with Mexico unsuitable, which sparked the Revolt of 1837 and a growing economic association with the expanding United States. The 1848 Mexican -- American War indirectly capitalized on this tension and created the U.S. New Mexico Territory. It was admitted to the Union as the 47th state on January 6, 1912.

Document 5: Pueblo Alto: Pueblo Alto ("High Village" in Spanish) is an Ancestral Puebloan great house and archaeological site located in Chaco Culture National Historical Park, northwestern New Mexico, United States. The complex, comprising 89 rooms in a single-story layout, is located on a mesa top near the middle of Chaco Canyon; 0.6 miles (1 km) from Pueblo Bonito, it was begun between AD 1020 and 1050. Its location made the community visible to most of the inhabitants of the San Juan Basin; indeed, it was only 2.3 miles (3.7 km) north of Tsin Kletsin, on the opposite side of the canyon. The community was the center of a bead- and turquoise-processing industry that influenced the development of all villages in the canyon; chert tool production was also common. It shares its mesa with another great house, Nuevo Alto, both of which are now protected within the borders of Chaco Culture National Historical Park. Storerooms at Pueblo Alto opened to the outside rather than into the interior rooms and there was a huge midden of pottery. This and chert found in the midden came mostly from the Chuska area 70 km (43 mi) to the west.
