There's many christians that live in Israel.
Plus, many Jews migrate there as throughout the ages, Israel has been conqured time and time again, which means Jews were then carted off to all the parts of the world, and many decendants of these Jews that were moved wish to return to their promised land.
I'd love to visit Israel, it sounds like a glorious place to go.
The Crusades were started by Pope Urban II with his speach in 1095, where he promised all those that went on the crusade remission for their sins, which he really was just using it as a ploy to get back all the lands that were taken from him by the Muslim turks.

Pope Urban II
Call to Crusade
November 27, 1095
Most beloved brethren: Urged by necessity, I, Urban, by the permission of God chief bishop and prelate over the whole world, have come into these parts as an ambassador with a divine admonition to you, the servants of God.
I hoped to find you as faithful and as zealous in the service of God as I had supposed you to be. But if there is in you any deformity of crookedness contrary to God’s law, with divine help I will do my best to remove it.
For your brethren who live in the east are in urgent need of your help, and you must hasten to give them the aid which has often been promised them. For, as the most of you have heard, the Turks and Arabs have attacked them and have conquered the territory of Romania [the Greek empire] as far west as the shore of the Mediterranean and the Hellespont, which is called the Arm of St. George. They have occupied more and more of the lands of those Christians, and have overcome them in seven battles. They have killed and captured many, and have destroyed the churches and devastated the empire.
If you permit them to continue thus for awhile with impurity, the faithful of God will be much more widely attacked by them. On this account, I, or rather the Lord, beseech you and Christ’s heralds to publish this everywhere and to persuade all people of whatever rank, foot-soldiers and knights, poor and rich, to carry aid promptly to those Christians and to destroy that vile race from the lands of our friends. I say this to those who are present, it is meant also for those who are absent. Moreover, Christ commands it.
All who die by the way, whether by land or by sea, or in battle against the pagans, shall have immediate remission of sins. This I grant them through the power of God with which I am invested.
Let those who have been accustomed unjustly to wage private warfare against the faithful now go against the infidels and end with victory this war which should have been begun long ago. Let those who for a long time have been robbers, now become knights. Let those who have been fighting against their brothers and relatives now fight in a proper way against the barbarians. Let those who have been serving as mercenaries for small pay now obtain the eternal reward. Let those who have been wearing themselves out in both body and soul now work for a double honour. Behold! On this side will be the sorrowful and the poor, on that, the rich; on this side, the enemies of the Lord, on that, his friends, Let those who go not put off the journey, but rent their lands and collect money for their expenses; and as soon as winter is over and spring has come, let them eagerly set out on the way with God as their guide.
O what a disgrace if such a despised and base race, which worships demons, should conquer a people which has the faith of omnipotent God and is made glorious with the name of Christ! With what reproaches will the Lord overwhelm us if you do not aid those who, with us, profess the Christian religion!
