Urbanization fueled the development of new industries, a growing middle class, and a more diverse population, all of which were favorable conditions for the blooming of Renaissance ideas and creativity.
4. Rise of Humanism: Humanism, one of the defining features of the Renaissance, was shaped by the experiences and knowledge gained during the Crusades.
