Theories of Empire, 1450-1800 [PDF ebook] 

Theories of Empire, 1450-1800 draws upon published and unpublished work by leading scholars in the history of European expansion and the history of political thought. It covers the whole span of imperial theories from ancient Rome to the American founding, and includes a series of essays which address the theoretical underpinnings of the Spanish, Portuguese, French, British and Dutch empires in both the Americas and in Asia. The volume is unprecedented in its attention to the wider intellectual contexts within which those empires were situated – particularly the discourses of universal monarchy, millenarianism, mercantalism, and federalism – and in its mapping of the shift from Roman conceptions of imperium to the modern idea of imperialism.
