Middle Ages was truly a tough time to be alive. This turbulent period spanned several centuries, from the 5th to the 15th centuries, and during these 1000 years, many changes swept through European societies.

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

Theodoric the Great lived in the period after the demise of the Western Roman Empire and had to deal with the results of this huge societal transition. He was an expansionist and sought to take control over the provinces of the Eastern Roman Empire, always setting his gaze to Constantinople.

Theodoric was a shrewd politician with an imperialist mindset and tried to find large areas for the Ostrogoths to live. He was known to murder his opponents, even in theatrical ways. The most famous account of his brutality was his decision to kill one of his opponents, Odoacer, at a feast and slaughter even some of his loyal followers.

Clovis I was the founder of the Merovingian dynasty and was the first king of the Franks. Clovis united the Frankish tribes under one rule and set up a system of government that would rule over the Frankish Kingdom for the next two centuries.

He took over the reins of the last remaining part of the Roman Empire that was once a great hegemony and that controlled most of the world. Justinian had a great ambition to restore the Roman Empire and even managed to recover some territories of the collapsed Western empire.

Being a skilled tactician, he expanded to North Africa and conquered the Ostrogoths. He also took Dalmatia, Sicily, and even Rome. His expansionism led to the great economic rise of the Byzantine Empire, but he was also known for his readiness to subjugate smaller peoples under his rule.

Justinian rewrote the Roman law that still serves as the basis of civil law in many contemporary European societies. Justinian also built the famous Hagia Sofia and is known as the last Roman emperor, while for Eastern Orthodox believers he earned the title of the Saint Emperor.

Asparuh is remembered as a hegemonic leader and father of the nation. Even a peak in Antarctica is named after him.

Wu Zhao ruled in the 7th century, during the Tang dynasty in China. She was the only female sovereign in Chinese history and spent 15 years in power. Wu Zhao expanded the borders of China while tackling inner issues like corruption in the court and revitalizing the culture and economy.

While being very attentive to solving domestic issues, Wu Zhao also set her sights on expanding Chinese territorial limits deeper into Central Asia and even waging wars on the Korean Peninsula. Besides being an expansionist, she made sure to invest in education and literature.

Ivar the Boneless

Ivar the boneless was a Viking leader and a semi-legendary Viking leader. We know that he was indeed a real person that lived in the 9th century and was the son of the famous Viking Ragnar Lothbrok.

Ivar was known as a cunning strategist that used many useful tactics in his battle. He led the Great Heathen Army in 865 to invade the seven kingdoms on the British islands to get revenge for his father’s death.

Ivar’s life was a mix of legend and truth, so it is hard to separate truth from fiction, but one thing is clear – he was a powerful leader.

Although not a king per se, Pope Urban II held great power as the leader of the Catholic Church and the ruler of the papal states. His most important contribution was to recover the Holy Land, the territories around Jordan River and the East Bank from the Muslims that settled in the region.

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.

The schism was not resolved until the death of Anacletus II who was then declared the Antipope and Innocent reclaimed his legitimacy and was confirmed as the actual pope.

He went as far as present-day Senegal and the Gambia and defeated many kings and leaders in the region.

Despite his heightened expansionism, Sundiata Keita did not display autocratic traits and was not an absolutist. The empire of Mali was a fairly decentralized state that was run like a federation in which each tribe had their ruler and representatives in the government.

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.
