The supports Renaissance Artists of Italia had got from Roman Popes were related with that Italia produce the most and the best artists, and for the reason of it Roman Popes and artists had close relations with each other beyond the classes, giving feedback to another. Popes exercises his influence over the entire arts to use the art works as a method of propagating Catholic doctrines and the superiority of theology. The artists Even enjoyed stable life, even though they had to draw about limited themes. However, the Papal court moving to Avignon, France which had powerful sovereign, the new era of Pope in France started, since then Italian Renaissance Art began in Firenze. This seems very unique, by judging that arts such as architecture made great strides in Rome depending upon the support of Roman Popes. The support of Roman Popes guaranteed artists` success, therefore it seems to be worth considering the relation between Renaissance Art and the detention of Pope in France. The crisis of the Avignon era, however, made the Pope`s authority focused on Rome. Furthermore, the rise of Renaissance in Firenze and the support of Medici and Mecenat affected by social and ideological change brought a development to Firenze art, and that made it possible to form Roman Church. By the religious and political events, the crisis of religious picture and religious arts was established, but works of the gifted artists supported by Popes, especially of Rennaisance era, made significant contributions to art. Even if the division, religious renovation of religion and the firmness of Christianity made by the authority of Pope and the issue of commitment of it after the Avignon era caused political and ideological chaos, the supports for artists by Popes were constant, and in the event the chaos and division gave rise to creative artists and the new trend of art.
