The First Crusade resulted in the successful conquest of Jerusalem and the establishment of a few tenuous Crusader states.
In response to the fall of these Crusader states, the second crusade was called in response in order to recapture the areas in question. However, it was a complete failure.
The Third Crusade was called in response to the fall of Jerusalem to Saladin and increasing Muslim successes in the Holy Land. However, the crusade immediately ran into problems, with leaders dying, returning home, and being unable to move inland. Ultimately the Third Crusade ended with a negotiated peace in which Christian pilgrims were given access to Jerusalem.
Pope Innocent III initiated the Fourth Crusade, which immediately went off of the rails, with the crusaders getting involved in Venetian-Byzantine politics, fighting Christians, and eventually sacking Constantinople without ever reaching the Holy Land.

There were 4 crusades in total with varying goals and degrees of success. They can be described as follows:

1st Crusade

  • Called by the Pope to recapture the Holy land from Muslims.
  • Resulted in Jerusalem being recaptured and the establishment of certain kingdoms known as Crusader states.

2nd Crusade

  • Goal was to recapture some of the Crusader states which had fallen under Muslim dominance.
  • Ended in failure as the Crusaders were defeated by the Seljuk Turks.

3rd Crusade

  • Called to end Muslim incursions into the Crusader territories as well as to recapture Jerusalem.
  • Partly ended in failure as the result was a negotiated peace which allowed Christians to visit Jerusalem.

4th Crusade

  • Called to help the Byzantine empire stem Muslim invasions.
  • Ended in failure as the Crusaders instead attacked the Byzantine empire and hastened its end.

In conclusion, the four crusades saw different results.
