Answer: It allowed both Christians and Muslims to enter Jerusalem.
Explanation:
The crusades were attempts by western Christians to recover the Holy land which had fallen to the control of Muslims.
The peace treaty between Richard and Saladin in 1192 at the end of the third crusade
granted Muslims control over Jerusalem yet it allowed unarmed Christian pilgrims and merchants to visit the city.
This treaty allowed both Christians and unarmed Muslim pilgrims to visit the Holy land.
