The painting of the Sistine Chapel ceiling by Michelangelo and of various rooms by Raphael in the Apostolic Palace are considered among the masterworks that mark the High Renaissance in Rome.
Also, during his papacy, the lead up to the Protestant Reformation produced increased tension in Christianity, which caused the Catholic Church to lose influence and political power in Europe.
Several of his predecessors were poor, unjust, and impious rulers who caused people to doubt the papal seat and the Vatican’s monopoly on religion.
During his reign, Julius II utilized his iconic status to his advantage, displaying his interest in the arts by placing himself on medals, emblems, and by commissioning specific artworks containing his image.
The most noticeable self-referencing image trend on the coins and works of art commissioned by Julius II was the "Della Rovere oak."
The Della Rovere coat of arms bore an oak tree and the family was referenced with the emblem of the acorn, which had mythological, Christian, and Republican Roman iconographic associations.
Sixtus IV had fabricated a lineage associated with the Della Rovere counts when he was a cardinal and saw an opportunity to ascend to the papal throne.
When Julius took the papal office, the condition of the Church was extremely poor, and he took the opportunity to expand it, modernize it, and leave his impression forever on the Vatican.
Della Rovere wanted the splendor of the new basilica to inspire awe in the masses, produce support for Catholicism and prove to his enemies he was a pious and devoted man.
Julius II’s Papacy is frequently criticized, for it is a common conception that he was keen for glory, which is reflective in his nickname, "The Warrior Pope" (Gosman, 50).
To say this is not to deny that messages may be read into them, but it should not be assumed that patrons would necessarily have cared about or understood or been motivated by theories and statements about their power and authority that may be coded into the works of art they paid for.
(Gosman, 55) Julius was, according to some scholars, a man who appreciated art, took pleasure in building, and merely wanted to create grand places in which to live, and that this motivation was much more important than the desire to project political ideas and images of his power.
