Why were the crusades organized?
The reason for organizing the Crusades was the liberation of the Holy Sepulcher from the hands of the Gentiles. Rumors about multiple murders of Christian believers in Palestine, robberies and any other crimes against Christianity were widely used.
The reasons for the trips were very different from the reason. It should be borne in mind that the main role in the management of European states at that time was played by the Catholic Church. A significant increase in the birth rate created a huge mass of people who needed food and other benefits. There was no way to provide them. Fearing riots, the church sent them to Palestine. But the main reason for the campaigns was the greed of the church. She wanted to retain and expand her influence in the East.
