The origins of the Crusade are in political turmoil. Middle of the 7th century to the middle of the 10th century, Islam gradually expanded (Riley-Smith 1). Half of the Christian world was conquered by Arab military. This includes countries that have established Christianity for centuries, such as Egypt, South France, South Italy, Sicily, Spain, Syria, Turkey (Riley-Smith 2). In the late 10th century, Europe and the Middle East were divided into Christian and Muslim hemispheres.
The 11th and 12th century Christian crusaders were numerous and complicated. The Christian Crusade Christian has built a tension between Christians and Muslims. In this article, I will explain the cause and effect of the medieval crusade. The importance of the Holy Land in the Islamic Bible, the Quran, and the Christian Bible is the most important reason for the Christian Crusade. The religious competition between the two religions is due to the belief that the two religions are two different gods. Muslims believe that God is a true God and Christians believe that God is a true God. Islam believes that the truth of God is the truth and has angered pilgrims who are trying to regain the sacred places of Bethlehem, Nazareth, Jerusalem, now dominated by Muslims since AD 638
Christian began crusades in the name of religion, and their religion was most affected. In the fourth Crusade, western Christians murdered Eastern Christians in Constantinople on the way. They will also dress Christians as they dress like Muslims. It is time when Orthodox Church and Catholic Church are completely separated and their conflict still exists. The Europeans have an important positive influence thanks to the Crusade. One of the biggest advantages is the trade of spices and fine fabrics. They also brought many medicines and treatments from Arabia and Persia, and the Crusade also helped the beginning of the Italian Renaissance.
A lot of things happened in the 4th Crusade. The Crusaders attacked the Zara witch as a Catholic Hungarian city. The Crusaders also fired the Constantinople, the Muslim District, the Christian District of Constantinople, as Christians believed that it was a traitor. Pope Innocent III summoned the Crusaders to free non-Holy lands from non-Christians. Venice offered to the Crusade in exchange for half of their wealth. As a result of this crusade, the crusade collapsed in 1204, some Christians were dispatched to Venice, Constantinople became ruined and the Greeks regained it.
