There is one civilization in world history came to be influenced by Eris: the Aztecs which begat the modern day Mexico. Once the Aztecs ruled the valley of Mexico where Mexico city now sits, parts of southern Mexico and Central America north of Nicaragua and their range could reached the region known as "Aztlan" where they might originated from between north of the tropic of Cancer in Mexico, central Texas and southern California. The Aztecs' nomadic ancestors might began in the present-day Southwest US (Arizona or New Mexico?) about 558 years (the year 970-975 AD?) before their conquest by Europeans (the Spanish) in 1521. Just like Eris makes on average 558 years to orbit the Sun. Right before the 2nd millennia AD, the ancestors of Mexico began to move down further into the Mexican peninsula, and after the 3rd millennia AD began, seems like recent decades of Mexican immigration northward to the US represents a "return" to an ancestral homeland, despite being under the US. I asked what does Eris represent to some countries in mundane astrology?
Perhaps the years 2079-2084 when Eris makes a second return in its orbital cycle: would Mexico either have a very indigenous majority (other than mestizos of mixed European-Amerindian descent) or the southwest US may be returned to Mexican rule after the land was annexed by the US after the Mexican-American war, 1846-48 and an earlier revolution by the Anglo-American Texas Republic 1836-45. Despite the destruction of the Aztec, Maya and MesoAmerican peoples or empires by 3 centuries of Spanish colonial rule, the Mexican people with indigenous roots mixed with the Spaniards declared independence in 1821 (or was it 1810?) and the pre-independence Spanish settlement of coastal California in 1769-1779. Independence 300 years after conquest, gain of land 250 years after (1760-70s), loss of land 250 years before (1830-40s) and possible extension 300 years before the sociopolitical "Reconquista", Eris may played a role in causing effects by certain alignments and positions in its orbital cycle to project changes in Aztec-based, yet Hispanicized Mexico.
