          "The building served as the capitol until 1907, when the Dawes Act finally dissolved the Cherokee Nation and Tahlequah became the county seat of Cherokee County, Oklahoma. The Cherokee National government was re-established in 1938 and Tahlequah remains the capital of the modern Cherokee Nation; it is also the capital of the United Keetoowah Band of Cherokee Indians.",
          "Some Cherokees fleeing the Federal Army, sent for the \"round up\", fled to the remote settlements separated from the rest of the Cherokee Territory in Georgia and North Carolina, in order to remain in their homeland. In the 20th century, their descendants organized as the Eastern Band of Cherokee Indians; its capital is at Cherokee, North Carolina, in the tribally-controlled Qualla Boundary.",
          "After Removal from their Alabama-Georgia homeland, the Creek national government met near Hot Springs which was then part of their new territory as prescribed in the Treaty of Cusseta. Because some Creeks fought with the Confederacy in the American Civil War, the Union forced the Creeks to cede over 3,000,000-acre (1,200,000 ha) - half of their land in what is now Arkansas. ... Served as the National capital after the American Civil War."

          "The capital city of the United States of America is Washington, D.C., and can be referred to formally as the District of Columbia or more informally as D.C. or Washington. In 2017, the city had a population of 6,131,977 and an approximate size of 68.34 square miles.",
          "This climate is prone to thunderstorms, which may be sometimes accompanied by tornadoes. The highest temperature ever recorded in D.C. was 106 °F in 1918, while the lowest was −15 °F in 1899. The economy of the capital is booming, with a steady performance compared to the other US states.",
          "Data shows that the capital consistently ranks first among the top ten US states in terms of GDP between 2009 and 2016. In 2016 alone, the GDP per capita was $160,472, a figure that is almost three times as large as that of the GDP of the second-highest state, Massachusetts.",
          "Tourism is the second largest contributor to D.C.’s economy, as the city receives an annual average of almost 20 million visitors. Aside from the obvious allure of visiting a city that is a country's capital, there are several other features that attract visitors from all over the world every year."
