The Middle Ages, which lasted from the 5th century to15th century, was the middle period of the division of the three traditions in European history.

The Middle Ages began with the decline of the Western Roman Empire (AD 476), and finally merged into the Renaissance and the Age of Exploration (geographical discovery). Another view is that the Middle Ages ended with the demise of the Eastern Roman Empire (1453).

The word "Middle Ages" was used by Italian humanist Biondo in the late15th century. Europe in this period did not have a strong regime to rule.

Feudal separatism brought frequent wars, and Catholicism imprisoned people's thoughts, which led to the stagnation of science and technology and productivity, and people lived in hopeless pain. Therefore, the Middle Ages or early Middle Ages are generally called "dark ages" in Europe and America. Traditionally, this is a period of slow development in the history of European civilization.

Crusade (Latin: Cruciata, 1096- 129 1) is a series of famous religious military actions with the permission of the Roman Catholic Pope, which lasted for nearly 200 years. Feudal lords and knights in western Europe launched nine wars against the eastern Mediterranean countries in the name of recovering the land occupied by Arab Muslims.

The cross is a symbol of Christianity, so everyone who takes part in the expedition wears the cross on his chest and arms, so he is called the Crusader.

At that time, Jerusalem, a holy place of Roman Catholicism, fell into the hands of Islam. In order to recover lost territory, Roman Catholicism made many expeditions to the east. But in fact, the Crusades were not confined to Islam. For example, the Fourth Crusade was aimed at the Byzantine Empire which believed in the Orthodox Church.

Crusaders established dozens of Crusader countries in the areas they occupied, the largest being the Kingdom of Jerusalem, in addition to the Principality of Antioch and the Kingdom of Tripoli.
