The 47 Most Important Historical Figures
History is full of people who marked a turning point in the evolution of humanity. Today, the world is what it is thanks to your thoughts, ideas, or actions, with a significance that often escapes our knowledge. To pay tribute to them, here’s a list of the 47 most important historical figures.
Of course, our selection is incomplete, as we could easily choose hundreds of heroes, writers, philosophers, and scientists from each country. Even so, this is a good starting point to get to know their stories and concerns. Are you ready?
The most important historical figures
Before we begin, we must first warn you about something: Our list doesn’t revolve around famous people because of their ethics, but rather because of the consequences that their ideas or actions have generated. While many of them changed the landscape for the better, others did nothing more than sow darkness.
Also, note that the list isn’t ordered according to importance. Each of the figures is accompanied by their date of birth and death. In some cases, we include the date that’s traditionally associated with these moments. Because some of these individuals lived centuries ago, a reliable record of exact dates isn’t always available. With this in mind, let’s get started.
1. Jesus of Nazareth (4 BC – 30-33 AD)
The leading figure in Christianity, Jesus of Nazareth was a Jewish preacher who lived during the first century AD. His schism today brings together more than 2.4 billion believers, almost 1.4 billion of whom are Catholics. His teachings have been the center of attention of theologians for two millennia. Jesus was born in Bethlehem in Judea and, according to tradition, was a descendant of King David.
2. Muhammad (570 – 632)
In the Islamic religion, Muhammad is the last of the prophets (who is preceded by Jesus, Moses, and Abraham, among others). According to tradition, the prophet founded Islam after a revelation from the archangel Gabriel in the cave of Hira. Today, there are more than 1.8 billion Muslims worldwide.
3. Christopher Columbus (1451 – 1506)
This navigator and cartographer served the Crown of Castile and directed the exploration that would result in the discovery of America. The Modern Age, and globalization along with it, began on October 12, 1492, at which time he disembarked on Guanahani Island (present-day Bahamas). He made a total of four trips before he died on May 20, 1506.
4. Julius Caesar (100 BC – 44 BC)
Gaius Julius Caesar was one of the most important politicians and soldiers in ancient Rome. His control of the Republic was surrounded by controversy and betrayal.
One of his greatest achievements was the Gallic War, which would extend Roman territory into parts of what are now France, Belgium, Switzerland, Germany, and the Netherlands. A plot hatched by some senators put an end to his life.
5. Alexander the Great (56 BC – 323 BC)
Alexander the Great was the king of Macedonia until his death. Aristotle was in charge of his education, and his reign is considered by historians as the beginning of the Hellenistic Period. His actions were an inspiration to other important historical figures such as Julius Caesar and Napoleon Bonaparte.
Alexander the Great is one of the most important heroic figures of antiquity.
6. Plato (427 BC – 347 BC)
Plato is one of the most important philosophers in the history of philosophy.

9. Johannes Gutenberg (1400 – 1468)
The inventor of the modern movable type printing press couldn’t be missing from this list of the most important historical figures.

10. Miguel de Cervantes (1547 – 1616)

14. Karl Marx (1818 – 1883)
Karl Marx completely shaped political, philosophical, and economic history after his death.

Marx focused on the idea that societies advance thanks to the dialectic of class struggle.
15. Isaac Newton (1643 – 1727)

20. Wolfgang Amadeus Mozart (1756 – 1791)
An undisputed genius in the history of music, Mozart is a figure who requires no introduction.

Aristotle’s works are a reference for Western political, religious, philosophical, scientific, and natural theory.

23. Neil Armstrong (1930-2012)
The first man to walk on the moon certainly deserves a place among the most important historical figures.
