Answer: One of the first major impacts of the crusades was that it increased interaction between different societies and groups of people. For instance, the crusades caused the religions of Christianity, Judaism and Islam to clash. In this conflict, people of all faiths travelled vast distances to fight over the city of Jerusalem, which each faith considered important to its religious heritage. This clash of religious ideals caused a sharing of ideas between the different religious groups and helped the principles of each religious faith to spread into new areas. Arguably, the clash between these three religions and this area of the world continues still today. Beyond religion, the interaction between different groups of people led to a spread of scientific and philosophical knowledge. The existence of the Silk Road had already caused a massive spread of ideas and knowledge across Eurasia, but the crusades continued and expanded the trend. At the outbreak of the crusades in the 11th century, the Middle East was a major center of learning and knowledge. Due to its geographical location, the major Middle Eastern civilizations were at the crossroads of the Silk Road and therefore benefited greatly from having access to both European and Asian knowledge. As such, when European crusaders came into contact with Middle Eastern peoples they were exposed to new ideas and inventions which eventually made their way back into European society. For example, the Europeans learned new understandings about mathematics from Middle Eastern mathematicians who were by far the most advanced at that time.
