After the fall of the Western Roman Empire, the people of the Middle Ages saw many transitions. They entered the Age of Discovery, struggled with plagues and diseases, opened to new cultures, and influences from the East, and waged terrible wars.

Given how many turbulent events happened in these several centuries, it is truly hard to write about the Middle Ages without considering the changemakers: Kings, queens, popes, emperors, and empresses.

In this article, let’s take a look at 20 medieval rules who wielded great power and were crucial during the Middle Ages.

Theodoric the Great – Rein 511 to 526

Pope Urban especially set his gaze on reclaiming Jerusalem that was already under Muslim rules for centuries. He tried to present himself as the protector of the Christians in the Holy Land. Urban started a series of crusades to Jerusalem and called upon Christians to take participation in an armed pilgrimage to Jerusalem and liberated it from its Muslim rulers.

The great schism was perhaps one of the most dramatic events in the history of the Catholic Church because, for the first time in history, two popes claimed to hold power. Innocent II struggled for many years to gain legitimacy from European leaders and their recognition of his papal title.

There was even an assembly created to check on his power and to make sure that his decisions and rulings are enforced among the population. All of these ingredients made the empire of Mali thrive until the late 14th century when it started to crumble after some states decide to declare independence.
