There were a total of nine major Crusades between 1096 and 1271.
The Knights Templar, a military order, was founded to protect Christian pilgrims traveling to the Holy Land.
They were not only fought in the Middle East but also in Europe, including the Baltic region and the Iberian Peninsula.
The Fourth Crusade, launched in 1202, diverted to Constantinople and resulted in the sack of the Christian city in 1204.
Saladin, the Muslim leader, recaptured Jerusalem from the Crusaders in 1187.
The Children's Crusade of 1212 was a disastrous attempt by European children to peacefully convert Muslims in the Holy Land.
The Crusades introduced Europeans to many new goods, such as spices, silk, and other luxury items, which helped stimulate trade.
The Crusaders established several states in the Middle East, including the Kingdom of Jerusalem.
The Crusades had significant religious, economic, and social impacts on both Europe and the Middle East.
Richard the Lionheart, King of England, became famous for his role in the Third Crusade.
The Crusades led to the creation of various knightly orders, including the Knights Hospitaller and the Teutonic Knights.
Many Crusaders took vows of piety and sought to gain indulgences, which they believed would reduce their time in purgatory.
The Crusades were partly motivated by the desire to control trade routes and wealth in the Eastern Mediterranean.
The legacy of the Crusades continues to influence Christian-Muslim relations and perceptions of the medieval period.
