full_context: Document 1: Rowlandton Mound Site: It was once thought that large civic sites in Western Kentucky such as Rowlandton Mound, the Twin Mounds Site and the Tolu Site were expansions of the Kincaid Mounds polity in nearby Southern Illinois in the 13th century, but archaeological excavations in 2006 by Dr. Kit Wesler of Murray State University have shown that this was not the case. It is probable that these civic sites were established originally by local Late Woodland peoples.
Document 2: State constitution (United States): Usually, they are much longer than the United States Constitution, which only contains 4,543 words. State constitutions are usually longer than 8,500 - words because they are more detailed regarding the day - to - day relationships between government and the people. The shortest is the Constitution of Vermont, adopted in 1793 and currently 8,295 words long. The longest is Alabama's sixth and current constitution, ratified in 1901, about 345,000 words long. Both the federal and state constitutions are organic texts: they are the fundamental blueprints for the legal and political organizations of the United States and the states, respectively.

Document 5: Admission to the Union: The Admission to the Union Clause of the United States Constitution, oftentimes called the New States Clause, and found at Article IV, Section 3, Clause 1, authorizes the Congress to admit new states into the United States beyond the thirteen already in existence at the time the Constitution went into effect.
Document 6: Incorporation of the Bill of Rights: Incorporation, in U.S. law, is the process by which American courts have applied portions of the U.S. Bill of Rights to the states. When it was first ratified, the Bill of Rights only protected the rights it enumerated from federal infringement, allowing states and local governments to abridge them. However, beginning in 1897 with Chicago, Burlington and Quincy Railroad v. City of Chicago, various portions have been held to be incorporated against state and local government through the Fourteenth Amendment.
Document 7: List of U.S. state birds: Below is a list of U.S. state birds as designated by each state's legislature. The selection of state birds began in 1927, when the legislatures for Alabama, Florida, Maine, Missouri, Oregon, Texas and Wyoming selected their state birds. The last state to choose its bird was Arizona in 1973. Alaska, California, and South Dakota permit hunting of their state birds. Pennsylvania has adopted a ``state game bird ''but not a state bird, while Alabama, Georgia, Massachusetts, Missouri, Oklahoma, South Carolina, and Tennessee have designated an additional`` state game bird'' for the purpose of hunting. The northern cardinal is the state bird of seven states, followed by the western meadowlark as the state bird of six states. Several states have extinct official animals, such as state dinosaurs in addition to state insects, state butterflies, state mammals and state reptiles.
Document 8: Constitution of Florida: Florida's first constitution as a U.S. territory was written and implemented in 1838. On March 3, 1845, Florida was granted admission into the Union as the 27th state.

Document 9: Oklahoma: State law codifies Oklahoma's state emblems and honorary positions; the Oklahoma Senate or House of Representatives may adopt resolutions designating others for special events and to benefit organizations. Currently the State Senate is waiting to vote on a change to the state's motto. The House passed HCR 1024, which will change the state motto from "Labor Omnia Vincit" to "Oklahoma-In God We Trust!" The author of the resolution stated that a constituent researched the Oklahoma Constitution and found no "official" vote regarding "Labor Omnia Vincit", therefore opening the door for an entirely new motto.
Document 10: Mound Bottom: Mound Bottom is a prehistoric Native American complex in Cheatham County, Tennessee, located in the Southeastern United States. The complex, which consists of earthen platform and burial mounds, a 7-acre central plaza, and habitation areas, was occupied between approximately 1000 and 1300 AD, during the Mississippian period.
Document 11: Pocahontas Mounds: Pocahontas Mounds (22 HI 500) is an archaeological site from the Plaquemine Mississippian culture in Hinds County, Mississippi, dating from 800 to 1300 CE. Two mounds from the site were added to the NRHP on two separate occasions, "Pocahontas Mound A" on November 25, 1969 as NRIS number 69000365 and "Pocahontas Mound B" on April 11, 1972 as NRIS number 72000694.
Document 12: Indian Mounds Park (Saint Paul, Minnesota): Indian Mounds Regional Park is a public park in Saint Paul, Minnesota, United States, featuring six prehistoric Native American burial mounds overlooking the Mississippi River. The oldest mounds were constructed 1,500 -- 2,000 years ago by people of the Hopewell tradition. Later the Dakota people interred their dead there as well. At least 31 more mounds were destroyed by development in the late 19th century. They were the tallest Native American mounds in Minnesota or Wisconsin (except for the unique 45 - foot (14 m) Grand Mound outside International Falls, Minnesota), and comprise one of the northwesternmost Hopewellian sites in North America. Indian Mounds Regional Park is a component of the Mississippi National River and Recreation Area, a unit of the National Park System. The Mounds Group is listed on the National Register of Historic Places. The 2014 nomination document provides a description of the archaeology and the context.
Document 13: Nacoochee Mound: The Nacoochee Mound (Smithsonian trinomial 9WH3) is an archaeological site on the banks of the Chattahoochee River in White County, in the northeast part of the U.S. state of Georgia, at the junction of Georgia State Route 17 and Georgia State Route 75. First occupied as early as 100-500 CE, the site was later developed and occupied more intensively by peoples of the South Appalachian Mississippian culture (a regional variation of the Mississippian culture) from 1350 to 1600 CE. One of their characteristic platform mounds is located at the site. A professional archeological excavation revealed a total of 75 human burials, with artifacts that support dating of the site.
Document 14: Arledge Mounds I and II: Most unusual is the proximity of the mounds to each other — while many groups of mounds are known in Ohio, they are not typically connected at the base as these two mounds are; only the Arledge Mounds and the McMurray Mounds, which straddled the border between Franklin and Madison counties, are known to have been conjoined. Although these mounds have not been excavated, archaeologists have proposed that they were built by the Adena culture, who are known to have built the McMurray Mounds.
Document 15: North Carolina: North Carolina was inhabited for thousands of years by succeeding cultures of prehistoric indigenous cultures. Before 200 AD, they were building earthwork mounds, which were used for ceremonial and religious purposes. Succeeding peoples, including those of the ancient Mississippian culture established by 1000 AD in the Piedmont, continued to build or add on to such mounds. In the 500–700 years preceding European contact, the Mississippian culture built large, complex cities and maintained far-flung regional trading networks. Its largest city was Cahokia, located in present-day Illinois near the Mississippi River.
