The dates listed in the following table indicate the year in which the city started to continuously serve as the state's sole capital. Most states have changed their capital city at least once—see Historical state capitals for details.
An insular area is a United States territory that is neither a part of one of the fifty states nor a part of the District of Columbia, the nation's federal district. Those insular areas with territorial capitals are listed below.
From 1774 to 1800, Congress met in numerous locations; therefore, the following cities can be said to have once been the United States capital:
Prior to becoming a territory of the United States in 1898, Hawaii was an independent country. Five sites served as its capital:
Before joining the United States under the Texas Annexation in 1845, Texas was an independent nation known as the Republic of Texas. Seven cities served as its capital:
Some Native American tribes, in particular the Five Civilized Tribes, organized their states with constitutions and capitals in Western style. Others, like the Iroquois, had long-standing, pre-columbian traditions of a 'capitol' longhouse where wampum and council fires were maintained with special status. Since they did business with the U.S. Federal Government, these capitals can be seens as officially recognized in some sense.
New Echota, now near Calhoun, Georgia was founded in 1825, realizing the dream and plans of Cherokee Chief Major Ridge. Major Ridge chose the site because of its centrality in the Cherokee Nation which spanned parts of Georgia, North Carolina, Tennessee and Alabama, and because it was near the confluence of the Conasauga and Coosawattee rivers. The town's layout was partly inspired by Ridge's many visits to Washington D.C. and to Baltimore, but also invoked traditional themes of the Southeastern ceremonial complex. Complete with the Council House, Supreme Court, Cherokee syllabary printing press, and the houses of several of the Nation's constitutional officers, New Echota served as the capital until 1832 when the state of Georgia outlawed Native American assembly in an attempt to undermine the Nation. Thousands of Cherokee would gather in New Echota for the annual National Councils, camping along the nearby rivers and holding long stomp dances in the park-like woods that were typical of many Southeastern Native American settlements.
