The Third Crusade was over. The Kingdom of Jerusalem now had to survive on its own. That this was possible is largely due to wise moves on the part of King Richard -- and luck.
When they had discussed this for some time, the wiser of them returned this reply to the royal enquiry: because the country had been devastated by disputes and disagreements, … the most essential thing was to create a new king whom everyone would obey, to whom the country could be entrusted, who would wage the people’s wars and whom the whole army would follow. If this did not happen before King Richard’s departure, they declared they would all leave since they were unable to guard the country by themselves.[i]
