"Deeply researched and powerfully written, Adrift on an Inland Sea offers a bold, innovative approach to the histories of early modern imperial spheres and colonial borderlands. Hal Langfur contrasts the Portuguese crown's efforts to govern these interior frontiers with its dependence on local inhabitants, who parlayed their experience of the sertões as guides and intermediaries."—Cynthia Radding, University of North Carolina, Chapel Hill

"Adrift on an Inland Sea is a beautifully narrated history of late eighteenth- and early nineteenth-century Brazil that reveals its hinterlands as crucial sites for imperial and national projects. Tracing information gathering as mediated by state agents, settlers, and Indigenous and African-descended peoples, Hal Langfur offers an innovative account of Brazilian territorialization and state power."—Kirsten Schultz, Seton Hall University

"[A]s Langfur demonstrates so well, it was easy enough for crafty individuals to confound officials in Portugal, allowing some to accumulate vast personal wealth (especially in land holdings), while the crown was unable to intervene. He suggests that such deceptions occurred in proportion to the desire of the Portuguese to exert increased control over their colony as the 18th century waned. Seemingly, not even scientists could be counted on for truthful reporting. It is hard to say whether this captaincy's experience extends to all of colonial Brazil. Regardless, for Minas Gerais, the author's effort is solid and provocative. Highly recommended."—R. M. Delson, CHOICE

"Clearly written, broadly framed, evocative, and at times amusing, [Adrift on an Inland Sea] is likely to appeal broadly to undergraduate and graduate students and historians of borderlands, empire, ethnohistory, Brazil, and the Atlantic world."—Judy Bieber, Hispanic American Historical Review

"Hal Langfur's Adrift on an Inland Sea: Misinformation and the Limits of Empire in the Brazilian Backlands sheds valuable light on spaces and processes in the history of colonial Brazil that have been overlooked and understudied, namely those taking place in internal frontier zones—the sertões, or backlands, between and beyond the enclaves governed by Portuguese rule, unstable and unincorporated spaces that were socially and culturally discontiguous."—Adriana Johnson, H-Environment

"Adrift on an Inland Sea is written in elegant prose, well-argued, and a superbly researched monograph that will undoubtedly become a mandatory reading for scholars of frontiers and borderlands of the Americas, Atlantic empires, Brazil, and history of science and knowledge production."—Fabricio Prado, Colonial Latin American Review

"Historical geographers will appreciate how Langfur reads archival materials in ways that question expedition leaders and draw attention to the informants and interlocutors who previously had been erased from the official expedition reports. The fact that the book is engaging and compelling as a narrative is yet another excellent characteristic of this significant contribution to Brazilian geography and history."—Christian Brannstrom, Journal of Latin American Geography
