But Philip II and Richard the Lionheart are able to engage with Saladin, and they are able to gain some land, in particular the region around Acre, and they're able to get some concessions from Saladin for unarmed Christian pilgrims to visit the Holy Land, especially Jerusalem. Now, Saladin dies as we approach the end of the 12th century. So in the beginning of the 13th century, the Fourth Crusades get launched. And these are interesting because the crusaders, with the help of Venetian traders, they actually engage with the claimant to the throne of the Byzantine Empire with the hope that if they can help them come back to the throne, that they can provide them the necessary resources in order to continue on with the Crusades. Well, they are able to put the claimant on the throne, but then an uprising takes that claimant down from the throne, and so the crusaders don't get their payment. But they want that payment badly. And so they decide to take Constantinople themselves.
