Tatiana Seijas is Associate Professor of History at Rutgers University. She writes about global migrations, long-distance trade, urban economies, and the joined history of freedom and slavery. Her research also aims to cross historiographical and geographical frontiers and to reconstruct the everyday experiences of people who were born without the privileges of power. Her publications include As Is She Were Free: A collective Biography of Women and Emancipation in the Americas (2020), and Asian Slaves in Colonial Mexico: from Chinos to Indians (2014), which won the Berkshire Conference of Women Historians Book Prize. Her latest monograph American Metropolis: The Making of Seventeenth-Century Mexico City is a new history about the working people who transformed a global city. Seijas is currently researching and writing “First Routes: Indigenous Trade and Travel in North America,” which recovers the history of Native merchants who forged routes of exchange between the Mesoamerican highlands and the Rio Grande Valley.
