The European Renaissance was a cultural movement that spread across Europe in the 14th to17th centuries. It began in Florence during the middle ages (1300's) and later spread to the rest of Europe. Although the Renaissance was traditionally and intellectual reform, it has been viewed as a bridge between the Middle Ages and Modern Era.
The Renaissance Era focused on the artistic developments of some prominent artists such as Da Vinci and Michelangelo, and saw revolutions in intellectualism. Part of this era also included political and social upheaval.
Those of the Renaissance Era employed the theory of humanism- a method of study in which people studied and search for realism and human in art. Scholars began to focus more on studying texts in Latin or ancient Greek. Beforehand, scholars had been focusing on texts written in Greek and Arabic works of natural sciences, philosophy and mathematics, instead of focusing on cultural and social texts.
Though it may seem to some that prominent members of the Renaissance Era rejected Christianity, it was quite the opposite. They still worshiped Christ but took a subtle shift in religion that reflected in other parts of life. The Greek New Testament was brought back ad helped pave the way for the Protestant Reformation.
