actually third crusade objective was to capture jerusalem from ayyubids saladin.they managed to capture some cities but not jerusalem.i think muslims lost jerusalem in sixth crusade.
Fourth Crusade commenced by Pope Innocent III led to destruction of Byzantine Empire at the hands of European armies instead ; this bunch was like (**** Jerusalem; lets plunder our Eastern brothers). This stupidity paved way for Ottomans to sack Constantinople later.
Actually, this idea is still alive and thriving. Western Europeans sometimes coming to the East for plundering and murdering. But - Russia is stronger, than Second Roman Empire. Another crusade, another attemp to сonquer Russia - and there will be no West at all. And they do realize this fact.
