the crusades were called the holy wars because the crusaders were fighting for Jerusalem which was considered the holy land by 3 monotheistic cultures and each one wanted it to be under their control.
What meant "holy" back then, is now called "freeing some brown people and bringing democracy"
A red herring veiling the real cause: greed of the few + gullibility of the many
The Crusades
Another name for the Crusades is the "Holy Wars." This term reflects the religious motivations behind the military campaigns, primarily aimed at reclaiming Jerusalem and other sacred sites in the Holy Land from Muslim control. The Crusades spanned several centuries, beginning in the late 11th century and continuing into the 13th century, and involved various European powers.
They were called crusades. There were a number of crusades to the Holy Land, but there were others, such as the Northern Crusades against pagans of the Baltic region, and the Albigensian Crusade against French heretics.
Europeans traveled to the Middle East to conquer the lands under Muslim control because of that was the supposed Holy Land, were Jesus was born, they were armies of religious fanatics who dropped everything to go fight for God. This caused amazing amounts of destruction and I would not be surprised if all the troubles in the Middle East today stem form this initial string of conflict and Holy Wars, as for the question it is one that needs to be answered in a library with lots of hours of research on the subject, including studying all the various battles that allowed for the Crusaders to enter so far into the Holy Land. I recommend you search Crusades or Holy Wars in wiki to get you started._________________________________________________________Comments on answer aboveThe so called holy lands are holy to the three religions Judaism, Christianity and Islam and not only holy to Christians to justify their Crusades warsThe Crusades wars were only to gain more political supports for the leaders of these wars in their countries and get more power by controlling other countries.The Europeans conquered also Muslim lands in Egypt, Iraq, Syria, Iran, Indonesia, Afghanistan, Pakistan, Algeria, Morocco, Tunisia, Libya, ...
