BIOGRAPHICAL DOSSIER
Life and historical role
Life and political setting
Isaac was the grandson of a sibling of Emperor Manuel I. While Byzantine governor in Cilicia he was captured by the Armenians; after his release he crossed to Cyprus with forged documents and in 1184 established an independent regime there, proclaiming himself emperor. The Angelos dynasty in Constantinople failed to dislodge him.
Role in the Crusades
In spring 1191 some ships of Richard's fleet were wrecked on the Cypriot coast in a storm, and Isaac mistreated the people and goods aboard. Landing on the island in May 1191, Richard defeated Isaac's army and conquered the island within weeks. Isaac is said to have been bound in silver chains.
Historical significance and source problems
The conquest of Cyprus made the island a supply base for the siege of Acre and then a Latin kingdom under the Lusignans. Isaac was held under Hospitaller guard and died around 1195. Niketas Choniates and the accounts of Richard's crusade in the Itinerarium Peregrinorum and Ambroise offer different perspectives.
