Because of the Crusades, the Christian as well as the Islamic world had 360 degrees changes and negative long-term effects. Before the crusades most of Christians were pacifists and regard Jesus Christ as the Prince of peace; but due to the Crusades, Christians' posture about violence totally changed. From their perspective violence could be justified if it was used just in wars to defend their church and God's mandates. Although at first, the Crusades were used in order for Christian pilgrimages to access the Holy city of Jerusalem, which was something good because the Muslims had taken control over the city and didn't let them in. Later on, the Crusaders lost their original path and promoted religious warfare for two and half centuries committing pillaging, murder among other atrocities not only against Muslims but also against any other vulnerable minorities.
Crusades also helped to elevate the authority of the papacy as the authoritative spiritual and temporal power in Europe before the emergence of the nation-states. Nowadays, because of the way Crusades develop most Muslims regard them as cruel and savage onslaughts by European Christians.
The Aztecs were a Pre-Columbian Mesoamerican people of central Mexico in the 14th, 15th and 16th centuries. They called themselves Mexica. The Republic of Mexico and its capital, Mexico City, derive their names from the word "Mexica".
The capital of the Aztec empire was Tenochtitlan, built on raised island in Lake Texcoco. Mexico City is built on the ruins of Tenochtitlan. The Spanish colonization of the Americas reached the mainland during the reign of Huey Tlatoani , Moctezuma II (Montezuma II). In 1521 Hernan Cortes and an allied army of American Indians that far outnumbered the defending Aztecs, conquered the Aztecs through germ warfare, siege warfare, psychological warfare, and direct combat.
According to their own history, when the Mexicas arrived in the Anahuac valley (Valley of Mexico) around Lake Texcoco, the groups living there considered them uncivilized. The Mexicas borrowed much of their culture from the ancient Toltec whom they seem to have at least partially confused with the more ancient civilization of Teotihuacan. To the Mexicas, the Toltecs were the originators of all culture; "Toltecayotl" was a synonym for culture. Mexica legends identify the Toltecs and the cult of Quetzalcoatl with the mythical city of Tollan, which they also identified with the more ancient Teotihuacan.
The center of the Aztec civilization was the Valley of Mexico, a huge, oval basin about 7,500 feet above sea level. The Aztec empire included many cities and towns, especially in the Valley of Mexico. The largest city in the empire was the capital, Tenochtitlan.
