Abstract
Continuing control over the political and developmental policies of Amazonia has become perhaps the last best hope of the Brazilian military establishment, which has seen its principal raisons d'etre—the threats traditionally thought to be posed by foreign enemies and internal subversion—disappear in recent years. Alfred Stepan has clarified the unusually high level of "military prerogatives" exercised in the post-1985 Brazilian political system, which relate to a wider theoretical consideration of political and biological diversity and are linked both directly and analogously, particularly in the Amazon region. In this regard, the direction of development policy in the greater Amazon region suggests the relevance of this military "policy prerogative" to the future of civil-military relations in Brazil, and the survival of one of the world's last great wildernesses.
