This volume contains papers from the fifth conference on the military orders held in London. It deals with the archaeological investigations at the Hospitaller castle at al-Marqab and examines aspects of the history of the military orders in the Latin East and the Mediterranean lands.

Scholarly interest and popular interest in the military orders show no sign of abating. This volume records the proceedings of the fifth conference in 2009, and, like the earlier volumes in the series, is essential reading for everyone interested in the progress of research into these powerful institutions.

The subjects in this volume focus on the history of the Latin East and its place in the context of Mediterranean trade and near eastern political developments.
