The Holy Land was and still is a place that is very important for the three major monotheistic religions: Islam, Judaism, and Christianity. There are many important religious sites in the Holy Land. This is the land now called Israel or Palestine. Jerusalem, Nazareth, Bethlehem and other religious sites fell under the control of Muslims during the Caliphate of Omar (634-44).

There were many different crusades. The most important and biggest Crusades took place from the 11th century to the 13th century. There were 9 large crusades during this time.

The smaller Crusades continued to the 16th century, until the Renaissance and Reformation.

The word "Crusade" is related to the word "Cross", and means a Christian holy war. There is also the Arabic word "Jihad", referring to a holy war fought by Muslims. All sides (Christians, Muslims, and Jews) believed very much in their religions. They also had political reasons for fighting.
