North and Central America 
|Indigenous peoples of the Americas||The whole of North America (including the Inuit of the Arctic).||Native Americans in the United States and the First Nations of Canada had established varying levels of governmental organization before contact with Europeans. The most advanced civilizations of North America were represented by the indigenous peoples in Mexico and Central America.||All the native peoples were eventually incorporated into the United States, Mexico, Canada and Central America, but many retain various levels of self-government and autonomy within those nations.|
|Cahokia||Illinois, Missouri, Indiana, Kentucky and parts of Ohio.||The population of the town at Cahokia exploded circa 1050 AD, indicating the establishment of a large "chiefdom".||The population of Cahokia dispersed in the 14th century, indicating the decline of the Cahokia "chiefdom".||Other political bodies existed in the Mississippian culture; the Mississippian culture article has a list of Known Mississippian Chiefdoms.|
|Huron Confederacy||Central Ontario.||Confederacy of five Iroquoian tribes and several smaller groups. Controlled trade in corn and furs in the upper Great Lakes area and sporadically through the Ottawa and St. Lawrence River valleys.||The Hurons were dispersed by the Iroquois in 1649. Many fled to the northern Lake Michigan region and Quebec, while a large group joined the Iroquois.|
|Iroquois Confederacy||Upstate New York and surrounding areas.||Formed before European contact; arguably as early as 31 August 1142, though also likely sometime in the 15th to 17th centuries.||The Treaty of Canandaigua, signed in 1794, established relations between the United States government and the Iroquois; the treaty is still in force, though the Confederacy is no longer effectively an independent nation.|
|Cherokee Nation||Originally in the southeastern United States, primarily Georgia, South Carolina, and North Carolina, and parts of Alabama and Tennessee. Parts of The Nation (and its government structures) ended up in present-day Oklahoma.||The original Cherokee Nation was unified from an interrelated society of city-states in the late 18th century. They enjoyed relatively peaceful relations with the Spanish, British, French, and later (with the exception of the Chickamauga factions), to the USA.||The modern Cherokee Nation, the Eastern Band of Cherokee Indians and the United Keetoowah Band of Cherokee Indians are the three federally recognized tribal successors to the original Cherokee Nation, being somewhat autonomous within the United States.|
|Vermont Republic||State of Vermont.||Organized by Ethan Allen and others in 1777 from territory claimed by New York and New Hampshire.||Admitted as a state to the United States of America in 1791.

A European prince was sought, but Spain prohibited any from taking the throne. Agustín I, in the meantime, was proclaimed emperor of Mexico in 1821.||In December 1822, Generals Antonio López de Santa Anna and Guadalupe Victoria wrote and signed the Plan of Casa Mata, an agreement between the two generals, amongst other Mexican generals, governors, and high-ranking governmental officials, to abolish the monarchy and replace it with the United Mexican States, which was done in 1823.||Emperor Maximilian I of Mexico, head of the Second Mexican Empire, adopted Agustin's grandsons.

The Webster-Ashburton Treaty in 1842 settled several U.S.-British border disputes dating from 1783, including the division of the former area of Indian Stream.|
|Republic of Texas||Texas and some surrounding territory.||Seceded from Mexico in 1836.||Voluntarily annexed to the United States of America and admitted as a state in 1845.||Annexation to the U.S. triggered the Mexican-American War the next year 1846.|

|Alta California||Southern California, centered in San Jose and Santa Barbara.||After U.S. occupation of Los Angeles in 1846, the Californios revolted and defeated an American force on 30 September 1846, and organized a government and an army.||Signed the Treaty of Guadalupe Hidalgo accepting American sovereignty over California on 2 February 1848.||By November 1846, the Californios had gained back control of all the territory south of San Francisco, leaving America in control of just San Diego and Monterey.|

His consort was Carlota of Mexico, a Belgian princess. France occupied Mexico, starting in 1861. Many Mexicans, including the nobility, backed his government.||Maximiliano's rule was blemished by constant conflict.

Maximilian was captured and, on orders of Benito Juárez, executed in the Cerro de las Campanas near Querétaro.|
