The Renaissance or otherwise known as the Rebirth was the mark of a new era of a way of life. It had taken place from the 14th to 16th centuries (or from 1350 AD to 1550 AD) and was a phase of changes which were more evident in culture and not a political event. The Renaissance had many causes from events occurring around Medieval Europe and in other parts of the world such as the Middle East and Asia.Some of those causes would be the Crusades, the Decline of Feudalism, the Rise of the Mongol Empire, and the Roles of Rulers, Nobles, Popes, and the Middle Class but the two most important causes are the Crusades and the Decline of Feudalism.During the Crusades, Crusaders brought in new thoughts and beliefs, which replaced the old thoughts and beliefs of other well known groups. They had also brought in new ideas and materials from other people in the Middle East such as scientific books of Aristotle, the Arabic numerals, mariners compass, and paper.There were three types of effects; social effects, economic effects and political effects. Some social effects of the Renaissance were manners and etiquette, the development of literature and fine arts, and scientific inventions and discoveries. Economic effects were the development of trade and commerce and Colonialism. Lastly the political effects were the rise of strong monarchies and a change in warfare. All these effects of the Renaissance play their own part in their own category they were placed under.
