20 Deaths That Changed the World

The assassination of Julius Caesar in 44 B.C. shook the already fragile political order of the Roman Republic. His assassins hoped to save Rome from dictatorship, but instead they helped spark a new civil war. This chaos ultimately paved the way for Augustus and the rise of the Roman Empire. 

The crucifixion of Jesus became the central event of Christianity. His disciples believed that his death and resurrection held a spiritual significance that transformed their understanding of God, salvation, and human history. Over time, Christianity spread throughout the Roman Empire and eventually became one of the world’s major religions.

Joan of Arc was burned at the stake in 1431 after helping to rally French forces during the Hundred Years’ War. Her death transformed her—who was then a controversial young military figure—into a martyr and a national symbol. Decades later, her conviction was overturned, and her reputation continued to grow. 

Martin Luther King Jr. was assassinated in 1968 while he was in Memphis to show his support for striking sanitation workers. His death sparked immense grief, anger, and unrest across the United States. It also helped provide the momentum needed for the passage, a few days later, of the Fair Housing Act.

The assassination of Archduke Franz Ferdinand in Sarajevo in 1914 helped trigger World War I. His death was not the sole cause of the war, but it set off a chain of events in a Europe already marked by alliances, rivalries, and military tensions. Within a matter of weeks, much of the continent was drawn into a conflict that would become one of the deadliest in history.

Abraham Lincoln was assassinated in 1865, just a few days after the Civil War had effectively ended. His death deprived the United States of the president who had guided the nation through secession and emancipation. Reconstruction then unfolded under weaker and more divisive leadership, with far-reaching consequences for former slaves and the future of civil rights. 

Alexander the Great died in 323 B.C., at the age of only 32, leaving behind a vast empire with no clearly designated adult heir to succeed him. His death sparked the Wars of the Diadochi, during which his generals fought over the territories he had conquered. This conflict divided his empire into Hellenistic kingdoms, spreading the Greek language, art, science, and culture throughout Egypt, Persia, and parts of Asia. 

Socrates was sentenced to death in Athens in 399 B.C. and chose to drink hemlock rather than renounce his principles. His death has become one of the most famous examples of intellectual courage in the history of philosophy. Through Plato’s writings, it has shaped ideas about ethics, justice, citizenship, and the reflective life. 

The assassination of John F. Kennedy in 1963 shook the entire world and brought to an end a presidency associated with youth, the tensions of the Cold War, the civil rights movement, and the ambitions of the Space Age. Lyndon B. Johnson seized upon this historic moment to advance major reforms, including landmark civil rights legislation and the “Great Society” programs. This event also deeply shook the postwar optimism of the baby boom generation and led to a questioning of authority.

Emmett Till was a 14-year-old Black teenager who was murdered in Mississippi in 1955 after being falsely accused of insulting a white woman. His mother, Mamie Till-Mobley, insisted that the funeral be held with an open casket so that the world could see what had been done to him. The images of his mutilated body helped galvanize the civil rights movement. 

Malcolm X was assassinated in 1965, after having been for years one of the most influential figures in Black political thought. His ideas had evolved considerably before his death, shifting away from his earlier separatist positions toward a broader vision of human rights on an international scale. His assassination brought this transformation to an end. After his death, he became an even more influential figure for movements focused on racial justice, self-determination, and resistance.

Cleopatra’s death in 30 B.C. marked the end of Ptolemaic Egypt. After her defeat alongside Mark Antony, Egypt became a province of the Roman Empire. Her death also helped consolidate Augustus’s power and shape the political order of the Mediterranean world.

Marie Antoinette was executed during the French Revolution in 1793. Her death symbolized the fall of the old monarchy and the anger directed at aristocratic privileges. She was not solely responsible for the crisis France was facing, but she became one of its most famous targets. 

Tsar Nicholas II and his family were executed by the Bolsheviks in 1918. Their deaths brought an end to the Romanov dynasty and made any simple restoration of the Russian monarchy far less likely. These murders have also become a powerful symbol of both revolutionary brutality and anti-communist memory. 

George Floyd was murdered by a Minneapolis police officer in 2020. Videos of his death went viral around the world and sparked one of the largest protest movements in modern history. These protests drew attention to police violence, systemic racism, and the need for accountability. 

Princess Diana died in a car accident in Paris in 1997. Her death sparked an immense outpouring of emotion among the public and forced the British royal family to rethink its relationship with the people. Diana had already upended expectations regarding royal celebrity, vulnerability, philanthropy, and media attention, and her death helped redefine the modern image of the monarchy.

King Edward VII died in 1910, bringing to an end a brief but significant reign during which he helped strengthen Britain’s ties with France and other European powers. His death marked the passing of a monarch closely linked to diplomacy, personal relationships, and the delicate balance of power in Europe. Just a few years later, the continent was plunged into World War I, and Britain entered the war under the reign of a very different king. 

Patrice Lumumba, the first prime minister of independent Congo, was assassinated in 1961. His death marked a decisive turning point in the history of postcolonial Africa and in Cold War politics. Lumumba embodied the hope for true independence, national unity, and freedom from all foreign interference, and his assassination remains an enduring symbol of the violence that surrounded decolonization.

Steve Jobs passed away in 2011 after helping to transform personal computing, music, animation, smartphones, and consumer technology. His death did not spell the end of Apple, but it profoundly altered the trajectory of the tech industry. It marked the transition from visionary and singular leadership to a new era characterized by corporate standardization, global patent battles, and competition.

George Washington’s death in 1799 came after he had already accomplished a revolutionary act: voluntarily stepping down from power, thereby setting a precedent for the peaceful transfer of power. His death made him a unifying national symbol of republican moderation, civic duty, and American identity. It also helped unite a then-divided American nation in mourning.
