Occupation of Sicily

In September 1190 Richard and Philip arrived in Sicily. After the death of King William II of Sicily in 1189 his cousin Tancred had seized power, although the legal heir was William's aunt Constance, wife of Henry VI, Holy Roman Emperor. Tancred had imprisoned William's widow, Queen Joan, who was Richard's sister, and did not give her the money she had inherited in William's will. When Richard arrived he demanded that his sister be released and given her inheritance; she was freed on 28 September, but without the inheritance. The presence of foreign troops also caused unrest: in October, the people of Messina revolted, demanding that the foreigners leave. Richard attacked Messina, capturing it on 4 October 1190.

The two kings stayed in Sicily for a while, but this resulted in increasing tensions between them and their men, with Philip plotting with Tancred against Richard. The two kings eventually met to clear the air and reached an agreement, including the end of Richard's betrothal to Philip's sister Alys. In 1190 King Richard, before leaving for the Holy Land for the crusade, met Joachim of Fiore, who spoke to him of a prophecy contained in the Book of Revelation.
