What is the illuminatis purpose?

The Illuminati was an organization (1776-1785) of enlightened intellectuals whose goal was the overthrow of an oppressive monarchy and the control of civil authorities by the Roman Catholic Church. The founder was Adam Weishaupt, a Bavarian writer and scholar. The organization was very unsuccessful in their endeavor because that monarch, Karl Theodor, Duke of Bavaria and Prince-Elector of the Holy Roman Empire, successfully destroyed the organization and imprisoned the leadership who were not able to flee, which ended the organization.
