What was the crusade of 1096-1099, and was there any?

This is the date of the First Crusade, when, after the appeal to the Holy See of the Byzantine emperor Alexy 1, Pope Urban 2 at the Clermont Cathedral called on the Christians of the West to stop civil strife and turn their sword towards the new formidable enemy – the Seljuk Turks, who oppressed the Christians of the East. As a result of this campaign, part of Anatolia (Asia Minor) was liberated from the Turks, Jerusalem was captured and the Kingdom of Jerusalem was founded. However, the cruelty of the Crusaders for many centuries sowed a blood feud between Islam and Christianity.
