Mexico's history reaches back 4,000 years, beginning with the Olmecs who lived in the Yucatan Peninsula. That remarkable civilization created those huge stone heads with developments that spearheaded and vitalized every subsequent Mesoamerican civilization that followed. The Olmecs, and the Maya, who succeeded them, created the concept of zero, an incredible development in mathematical computation. This book begins with the Olmecs, tracing successor civilizations to the last Mesoamerican Empire, the Aztecs. I describe Aztec life, ritual, cuisine, and development until, in August 1521, this civilization was conquered by Spanish conquistadors. Much of the Aztecs, their people, and royalty are known today by way of Spanish ethnographers and historians who authored codices writing and describing what they saw even as that civilization was changed. That change was permanent. Aztec ritual and its polytheism were altered by Spanish missionaries and enforced by the Inquisition. From 1521 until 1821, Spanish Colonial authorities imposed forced labor in varying forms. Colonialism was overthrown in 1821, and Mexico now entered a new era. This book describes those changes as well as the challenges the government today faces in addressing many disparities in its policies. Healthcare challenges, with systemic poverty as well as the drug war preoccupies much energy in the government's efforts to address them. Mexico also has a large Jewish population whose history was marked by secrecy and Spanish efforts to eradicate this ancient religion. Today's Zocalo, in the heart of Centro Historico, was the place where Jews were burned to death in public admonition against Jewish practice. Another site for such death was the nearby ex-Convento of San Diego, opposite the Grand Palace de Belles Artes. Today's Jews are thriving, and Mexico-Israel relations are strong. This book would not be complete without describing my visits to the country. In My Visit, I describe the different ports I visited while aboard cruise ships. But many more months in the country were spent in San Miguel de Allende and in Mexico City. I describe these visits, their people, and the many nuances of Mexican life. The Mexican constitution recognizes 69 ethnic languages and speakers who are scattered but who primarily live in its southern states. Many ethnic languages are so diverse, that their dialects are unintelligible to the same language group. Language creates the core bonds of society and such multiplicity provides insight into the huge diversity of identity and of life in Mexico. This book is the 14th in the Journey series and is my first book on the American continent. I hope I have done justice to the vast complexity of this society.
