No Reinaert, there was no united european political program the get rid land off nasty men. The ruling parties/kings in Europe didn't have this united social platform. If you are aware of any documents from way back stating otherwise, you are welcome to change my mind.
You are giving to much credit to one force being able to organize complicated ventures for 200 years. Usually there is bunch of small elements coming together in certain order to culminate in a big effect, like crusades this time. The elemental, quantitative, partial, many different things, if they work together they often mask and mislead people in believing that there is one universal, united force or organization controlling things.
I agree that greed or getting rich was one of main factors going to crusades, or many other war. Other factors are:
- Religion and promise of comfy afterlife. Life doesn't end after death, so no big deal if I die.
- The "Holy Land" was long time in christian hands, and was conquered by Muslims. This was a huge reason in Europe to go save the Christ homeland from infidels.
- Male predisposition to war is another big one. Give young guys a good reason and weapons to fight, and they are more than ready. For their whole childhood tell them romantic stories about great ancestor warriors (indoctrination), and you have an army of new martyrs. You don't need to twist guys arms to listen to the war stories, that's our genetic predisposition too.
- Also, the times were quite good in Europe, there was money to spend for the crusades. Not sure what was the cost of crusades, but we are talking about moving hundred of thousands of people and equipment through Europe and the sea. There were no new crusades organized in 1300 hundreds when big famine and black death came and ruined Europe.
