How to justify a crusade? The conquest of Livonia and new crusade rhetoric in the early thirteenth century

This article addresses the issue of how it was possible to justify a crusade to a region, such as the eastern shore of the Baltic, where there were no sacred shrines to protect or Christian lands to reconquer. Adopting a pluralist perspective of crusades, it argues that the Livonian crusade of the early thirteenth century offers some interesting clues to the new developments of crusading ideology. Conceiving of the conquest and conversion of Livonia as a crusade, albeit not quite equal to the liberation of Jerusalem, its initiators and apologists employed legal and rhetorical devices to justify the occupation of a region under the auspices of a crusade. This article examines these strategies through the medium of contemporary chronicles and papal letters.
