Mexico City was America's largest city in the seventeenth century - a genuine metropolis. In this deeply researched book, Tatiana Seijas reveals a rich tapestry of stories about essential workers who remade and transformed the city during this period. Her narrative style carries readers to a unique place and time with residents from around the world who sold food, facilitated transportation, provided care, and valued the city's silver. Free and enslaved people from Africa and Asia, immigrants, and Native Americans pursued opportunities in a wealthy, yet deeply unequal environment, where working people claimed parts of the city for themselves. They carved out spaces to create new businesses and protect their livelihoods, altering the cityscape itself in the process. American Metropolis brings Mexico City to life from the perspective of the working people who transformed this early modern metropolis.
