Book excerpt: Roots of Empire is the first monograph to connect forest management and state-building in the early modern Spanish global monarchy. The Spanish crown's control over valuable sources of shipbuilding timber in Spain, Latin America, and the Philippines was critical for developing and sustaining its maritime empire. This book examines Spain's forest management policies from the sixteenth century through the middle of the eighteenth century, connecting the global imperial level with local lived experiences in forest communities impacted by this manifestation of expanded state power. As home to the early modern world's most extensive forestry bureaucracy, Spain met serious political, technological, and financial limitations while still managing to address most of its timber needs without upending the social balance.
