In 1190 Richard I of England arrived in Sicily at the head of a large crusading army on its way to the Holy Land. Richard immediately demanded the release of his sister, William II's wife Joan, imprisoned by Tancred in 1189, along with every penny of her dowry and dower (in response of her vocal support of Germans). He also insisted that Tancred fulfil the financial commitments made by William II to the crusade. When Tancred balked at these demands, Richard seized a monastery and the castle of La Bagnara.
