Explanation: 1. Under the kingship of Leo III, the destruction of icons was carried out, on the grounds that the worship of icons is considered heresy. It is known as the iconoclasm, and it implies a very strict and incorrect interpretation of the commandments of respecting one God, without making any statues and images, because this is considered idolatry. In the case of icons, they were not subject to worship but a way to speed up prayer to one God with the help of sacred characters on the icons.
2. Hagia Sophia was originally built as the Orthodox Church in Byzantium, then converted to Mosque after the fall of Byzantium, and today it is a museum, a symbol of grand medieval architecture, and a symbol of Istanbul. It is dedicated to the Holy Wisdom, built in the 6th century under the reign of Justinian I, and represents the perfect combination of the symbol of Christianity with the artistic details of Islam, subsequently added by the Turks.
3. Serfs were peasants who held a low position in the medieval hierarchy. Although they were not slaves, they did not have their own land, but they lived in the possessions of nobles and lords, and worked for them. In turn, they had everything they needed in terms of food and other needs, but their status was related to their master. Their master could not sell them, since in fact they were not slaves, they had the opportunity to produce food for themselves on the master's the land, and in return would pay to their master in the form of labor.
4. After King Edward died in 1066, he was succeeded by his brother-in-law, nobleman Harold Godwinson. Godwinson launched an army in the south of England during the Norman Invasion, and at the Battle of Hastings he was defeated by the William the Conqueror who took over the throne of England.
5. The Great Schism or the split in the Christian Church occurred in 1054. Thus, officially two Christian Churches, the Roman Catholic in the West, and the Orthodox in the East were officially formed, although unofficially they already existed before. The reasons for the split have been blunted for centuries before, and they were both political and religious. Some of the political ones were created even with the division of the Roman Empire. The official language in the Church in the West was Latin, in the East of Greece, and slowly began to diverge. Some of the Pope, after the fall of the Western Roman Empire, relied on the West European kings for their support, and thus diminished the significance of the Patriarch in Constantinople. Regarding religious reasons, the Western Church regarded itself as the only true Catholic Church, while on the other hand, the Church in Constantinople considered itself as to be right and one who followed the early tradition, hence the "Orthodox". In addition, there were differences in attitudes and opinions regarding the nature of the Holy Spirit. The ultimate official split occurred in 1054, when the Pope and Patriarch excommunicated each other.
6. The Crusades took several centuries, and the starting point was the liberation of the Holy Land from the Muslims. During the Crusades, there were many innovations in the mode of warfare, commercial and trade activities that were promoted. In addition, it will increase the royal power, especially thanks to certain periodic successes of the Crusades, but also because of the great wealth that has been brought. Although Jerusalem itself was conquered several times by the Crusades and was under Christian power, in the end, the Holy Land, as well as many parts of the Middle East and the Mediterranean, remained in the power of the Muslims.
