Thirteen papers from a conference held in Barcelona in 2005 on the subject of 'War and territory in the Roman world: historical and archaeological approaches'. The contributors consider the relationship between the army and society, between the emperor and his army, between warfare and the environment, as well as more specific subjects: the representation of military power; the relationship between local and central power, especially at the frontiers of the empire; imperial administration; changes in imagery on coinage; war and the management of human and material resources. Seven of the papers focus on the Iberian peninsula whilst the rest look towards the empire as a whole. Text in English, Spanish, French and Italian.
