The Aztec World, From Aztlan to Tenochtitlan

The Mexica did not arrive in an empty world. Before Tenochtitlan rose from the lake, the Basin of Mexico was already packed with old cities, ruined pyramids, dynastic claims, hostile shore towns, sacred hills, tribute routes, wetland fields, salt water, fresh springs, and memories that could still make or break a ruler. Teotihuacan stood in ruin. Tula survived as a political name. Culhuacan carried old prestige. Azcapotzalco held power. Texcoco watched the eastern waters. Into this crowded, dangerous basin came a people whose origin was remembered through Aztlan, migration, divine command, hardship, service, and humiliation. The Aztec World: From Aztlan to Tenochtitlan follows that rise without stripping away the pressure of the ground beneath it. This is the story of a lake city built where mud, reeds, salt water, flooding, and enemy towns made survival uncertain. It moves through painted migration records, foundation signs, royal marriages, Tepanec domination, the Triple Alliance, tribute lists, market life, canals, causeways, aqueducts, temple precincts, sacred warfare, imperial expansion, Spanish entry, siege, and the breaking of the island capital. Drawing on codices, Nahua histories, colonial chronicles, archaeology, temple excavation, tribute records, and the surviving geography of the Valley of Mexico, this book treats Tenochtitlan not as a sudden wonder, but as the most forceful answer to a basin that had been testing cities for centuries. The Mexica learned the valley s rules, then turned them into empire: water into defense, ancestry into authority, tribute into supply, ritual into command, and an island settlement into the capital of the Aztec world.

Luke Reagan is a qualified historian with a lifelong devotion to the ancient cultures of Mesoamerica and the wider Americas, with particular studies in the Huastec, Zapotec, Teotihuacan, Toltec, Mixtec, and Aztec, or Mexica, worlds. His work is also shaped by an intense interest in Spanish history in the New World, especially the first encounters between Indigenous civilizations, explorers, chroniclers, soldiers, missionaries, and antiquarians. A lifelong collector of *National Geographic Magazine*, Reagan grew up with exploration, archaeology, and historical discovery as part of his intellectual environment, while his father and uncle were partly involved in the development of Lidar, the remote-sensing technology now used to reveal ancient landscapes, hidden settlements, and buried architectural systems.

Reagan's personal idols include Hiram Bingham, John Lloyd Stephens and Frederick Catherwood, and Percy Fawcett, explorers and antiquarians whose field accounts, drawings, controversies, ambitions, and obsessions helped bring ancient American sites into public imagination. His own interests follow that same line of inquiry, moving between ruins, archives, maps, expedition literature, colonial records, and the material remains of cultures too often reduced to footnotes. He comes from three generations of Reagans who fought for the rights of Native Americans in Texas and the wider region, giving his historical work a personal stake beyond scholarship alone. His mother's involvement in archaeoastronomy, especially at Chaco Canyon and Ancestral Puebloan sites, further shaped his interest in how ancient peoples read the sky, built sacred landscapes, and encoded cosmology into architecture.

Luke Reagan's work stands at the meeting point of historical research, exploration history, Indigenous cultural study, Spanish colonial history, archaeoastronomy, and the enduring mystery of ancient American civilizations.
