This volume presents the first full English translation of four key texts from the dispute between Juan Ginés de Sepúlveda and Bartolomé de las Casas regarding the justice of Spain's invasion of the Americas, culminating in their famous debate in Valladolid in 1550-51. An impassioned defence of the invasion, Sepúlveda's Democrates secundus (composed around 1544) amplified the controversy within Spain about the justice of its activities in the Americas. When Las Casas schemed to block publication of Sepúlveda's manuscript, Sepúlveda wrote an Apologia (1550) in its defence. Tensions were so high that Emperor Charles V called a temporary halt to undertakings in the Americas and convoked a meeting of theologians and jurists in Valladolid to address the matter. Here, Sepúlveda and Las Casas debated bitterly. Las Casas subsequently printed a composite record of the Valladolid deliberations (Aquí se contiene una disputa o controversia, 1552). Sepúlveda retaliated by penning a furious response (Proposiciones temerarias y de mala doctrina, around 1553-54) and strove to have Las Casas' text banned by the Inquisition. The debate between Sepúlveda and Las Casas was a pivotal moment in the history of international legal thought. They argued over fundamental matters of empire and colonial rule; natural law and cultural difference; the jurisdiction of the Church, responsibilities of Christian rulers, and rights of infidel peoples; the just reasons for war and grounds for resistance; and the right to punish idolatry, protect innocents from tyranny, and subjugate unbelievers for the purpose of spreading the Christian faith. With a detailed scholarly introduction that elucidates the complex story of these four controversial texts and reflects on the impacts of Sepúlveda's ideas, which continue to be felt in the theories and practices of war today, this book is a must-read for all those interested in the fields of history, political science, international relations, and colonial studies.

Was the Roman Empire just? Did Rome acquire her territories through just wars, and did Rome's rule exert a civilizing effect, ultimately beneficial for its subjects? Or was Roman imperialism a massive injustice - the bellicose conquest and absorption of countless peoples and large swaths of territory under false pretences, driven by greed and a lust for domination and glory? In The Wars of the Romans (1599), the important Italian jurist and Regius Professor of Civil Law at Oxford University Alberico Gentili (1552-1608) argues both sides of the debate. In the first book he lays out the case against the justice of the Roman Empire, and in the second book the case for.
Gentili's polemic and highly engaging work helped pioneer the use of Roman law and just war theory in what became a leading international law approach to the enduring questions of the justice of empire. Writing in the wake of the first wave of European colonial expansion in the Americas, and relying on models of the controversy about Roman imperialism from Cicero to Lactantius and Augustine, Gentili developed the arguments which were to become pivotal in normative debates concerning imperialism. In this work Gentili, a consummate Roman law scholar, frames the moral and practical issues in a combination of Roman legal terminology and the language of natural law, a combination which was to prove highly influential in the literature from Grotius onward on natural law, the law of nations and what eventually became international law.
