Smallpox was one of the deadliest diseases in human history, causing immense suffering and death for thousands of years. In the 20th century alone, it claimed the lives of around 300 million people, rivaling the devastation of the Spanish flu. Unlike flu survivors, those who survived smallpox often faced lifelong consequences such as blindness, infertility, and severe scarring. This disease did not discriminate, affecting everyone from royalty to commoners, and even toppling empires. However, in the mid-20th century, a global effort led by the World Health Organization (WHO) successfully eradicated smallpox, with the last natural case recorded in 1977. Humanity was finally free from this ancient scourge.
Smallpox was a particularly vicious virus. Once inhaled, it remained dormant for about 12 days, silently preparing its attack. On the 13th day, symptoms like headaches, back pain, chills, and vomiting would emerge. By the 17th day, painful pustules appeared in the throat and spread across the skin, covering the body in pus-filled lumps. Depending on the strain, the mortality rate could be as high as 30%. Survivors often bore the scars of their ordeal, and some were left blind or infertile.
The exact origins of smallpox are still debated. Some evidence suggests it may have existed as early as 10,000 BC, while other research points to a later emergence in the 16th century AD. Most historians agree that smallpox was present by 1570 BC, during Egypt’s New Kingdom. Mummies from this period, including Pharaoh Ramesses V, show signs of the disease.
Smallpox primarily affected children, especially those in crowded living conditions where the virus could spread easily. Although it was less contagious than diseases like measles, once it took hold, it spread rapidly. Historical records, such as a 14th-century Hittite tablet, describe pandemics that devastated populations, including rulers and common citizens alike.
In 430 BC, during the Peloponnesian War, Athens was struck by a devastating plague that killed a third of its population. Historian Thucydides documented its terrifying symptoms, which included high fevers, convulsions, and pustules. While the exact cause remains unknown, smallpox is a likely candidate.
Centuries later, the Antonine Plague hit Rome around 165 AD, possibly brought from China via the Silk Road. This outbreak killed millions, with symptoms like fever, diarrhea, and skin eruptions. At its peak, over 2,000 people died daily in Rome, including Emperor Marcus Aurelius. The plague’s impact was so severe that it may have weakened Rome’s military defenses.
As smallpox ravaged early empires, it also inadvertently increased their resistance to the virus. In the early 16th century, smallpox reached the New World. In 1520, an infected individual arrived in Mexico with Hernán Cortés’s expedition, leading to a catastrophic outbreak that killed up to 40% of Tenochtitlan’s population. The indigenous peoples had no immunity, resulting in devastating losses.
In the Andes, smallpox preceded European arrival, contributing to the Inca Empire’s decline. By the time Francisco Pizarro arrived in 1532, the empire was already weakened by the disease. Contrary to popular belief, smallpox was not deliberately introduced to Native Americans by colonists, although there was one documented instance in 1763 when British forces considered using it as a weapon during the French and Indian War.
By the 18th century, smallpox was a grim reality in Europe, killing around 400,000 people annually. However, some regions began to control the disease through variolation, a process of inoculating healthy individuals with material from infected patients.
In 1796, Edward Jenner, a surgeon in Gloucestershire, made a groundbreaking discovery. He observed that milkmaids who contracted cowpox did not get smallpox. Jenner tested this by inoculating a young boy, James Phipps, with cowpox material, and the boy became immune to smallpox. This marked the beginning of vaccination, a term derived from the Latin word for cow.
Despite initial skepticism, Jenner’s work gained acceptance, and vaccination spread across Europe and beyond. By the mid-20th century, much of the Western world had defeated smallpox. The last U.S. case was reported in 1949, and in 1980, the WHO declared the world free of smallpox.
Today, smallpox exists only in two secure laboratories, and while some advocate for their destruction, others argue they are necessary for future research. The eradication of smallpox is a testament to humanity’s ability to unite against a common enemy. It serves as a beacon of hope, showing that with cooperation and funding, we can overcome even the most formidable challenges posed by infectious diseases.
Research and create a detailed timeline of the key events in the history of smallpox. Include its origins, major outbreaks, the development of the vaccine, and its eventual eradication. Present your timeline using a digital tool or poster format, and be prepared to discuss the impact of each event on society.
Engage in a role-play activity where you and your classmates debate the ethical implications of variolation and vaccination in the 18th century. Assume the roles of historical figures such as Edward Jenner, local physicians, and concerned citizens. Prepare arguments for and against the use of early vaccination techniques.
Examine primary source documents, such as Thucydides’ account of the plague in Athens or records from the Antonine Plague. Analyze these texts to identify descriptions of symptoms and societal impacts. Write a short essay comparing these historical accounts to modern understandings of smallpox.
Imagine you are living in the 18th century and tasked with designing a public health campaign to promote smallpox vaccination. Create posters, pamphlets, or a speech that would persuade the public of the benefits of vaccination. Consider the challenges of overcoming skepticism and fear.
Conduct a research project on the science behind vaccination, focusing on how Edward Jenner’s discovery led to the development of modern vaccines. Present your findings in a presentation or report, highlighting how vaccines work and their role in preventing diseases today.

It’s one of the worst diseases in history: smallpox. For millennia, it was a scourge of mankind, inflicting death wherever it appeared. In the 20th century alone, it killed around 300 million people—almost as many as the Spanish flu. While survivors of the flu returned to normal, survivors of smallpox were often left with lifelong damage, including blindness, infertility, and disfigurement. This disease affected people from all walks of life: princes, pharaohs, emperors, queens, artists, warriors, and workers alike. Smallpox felled empires and annihilated cities, until one day it stopped. In the mid-20th century, a push by the World Health Organization saw smallpox become the first disease to be completely eradicated, with the last natural case recorded in 1977. After thousands of years of suffering, humanity was finally free.
But what was this virus we drove to extinction? Where did it come from, and how did it affect the story of humanity? Today, we’re diving into the life of one of history’s great plagues and how it shaped our modern world.
Of all the nasty viruses that have afflicted mankind, few have been as severe as smallpox. Once inhaled, it stays hidden for around 12 days, almost like an army laying the perfect ambush. During this time, life carries on as normal, but on day 13, the first symptoms appear: headaches, back pain, chills, and vomiting. As the 17th day approaches, pustules start to appear inside the throat and spread across the skin. Every inch of the body that the virus touches breaks out in pus-filled lumps. Depending on which version of the virus you’ve contracted, your chances of death could range from 3% to a staggering 30%. Surviving might be even worse, as the pustules leave behind hideous scars, and you may be left blind or infertile.
The exact origins of smallpox are still a mystery. Some suggest it may date back to as far as 10,000 BC, while research in 2016 concluded it may have appeared as late as the 16th century AD. For this discussion, we’ll go with the majority opinion, which states that smallpox first appeared by 1570 BC, coinciding with the start of Egypt’s New Kingdom. Mummies from this era show signs of infection, including Ramesses V, who had dried pustules on his cheeks.
While smallpox afflicted adults, the majority of its victims were children, particularly those living in cramped quarters where the virus could spread easily. Although smallpox was relatively non-contagious compared to diseases like measles, once it took hold, it spread rapidly. Historical records, such as a 14th-century Hittite tablet, describe pandemics that swept through regions, killing rulers and countless others.
If you ever find yourself in possession of a time machine, avoid Athens in 430 BC. During the second year of the Peloponnesian War, a disease known as the Plague of Athens arrived, killing around a third of the population. The historian Thucydides described its horrifying symptoms, which included violent fevers, convulsions, and pustules. While we don’t know the exact cause of the plague, smallpox is a major contender.
Nearly six centuries later, the Antonine Plague arrived in ancient Rome around 165 AD, likely brought from China via the Silk Road. This plague would kill millions, with symptoms including fevers, diarrhea, and skin eruptions. At its height, over 2,000 people died each day in Rome, including Emperor Marcus Aurelius. The death toll was staggering, and it may have contributed to the military’s inability to defend Rome’s borders.
As smallpox devastated early empires, it also inadvertently strengthened their resistance to the virus. Fast forward to the early 16th century, when smallpox made its way to the New World. In 1520, a ship carrying an infected individual landed in Mexico, coinciding with Hernán Cortés’s expedition into the Aztec Empire. Smallpox wreaked havoc, killing up to 40% of the population in Tenochtitlan. The indigenous peoples had no immunity to the virus, leading to catastrophic consequences.
In the Andes, smallpox arrived ahead of the Europeans in 1528, contributing to the downfall of the Inca Empire. By the time Francisco Pizarro arrived in 1532, the empire was already weakened by the disease.
Contrary to popular belief, smallpox wasn’t deliberately introduced to the Native American population by colonists. It had already swept through the Americas, decimating indigenous populations. However, there was one documented instance in 1763 when British forces considered using smallpox as a weapon against Native Americans during the French and Indian War.
By the 18th century, smallpox was a grim reality in Europe, killing around 400,000 people annually. However, other continents were already bringing the disease under control through a process called variolation, which involved inoculating healthy individuals with material from infected patients.
Edward Jenner, a surgeon in Gloucestershire, made a groundbreaking discovery in 1796. He noticed that milkmaids who contracted cowpox did not get smallpox. Jenner conducted an experiment using cowpox material to inoculate a young boy, James Phipps, who later proved immune to smallpox. This marked the beginning of vaccination, a term derived from the Latin word for cow.
Despite initial skepticism, Jenner’s work gained recognition, and vaccination spread across Europe and beyond. By the mid-20th century, much of the Western world had defeated smallpox. The last U.S. case was reported in 1949, and by 1980, the World Health Organization declared the planet smallpox-free.
Today, smallpox exists only in two carefully guarded labs, and while some argue for their destruction, others believe they may be necessary for future research. The story of smallpox is a testament to humanity’s ability to come together to combat and ultimately eradicate a disease that had plagued civilization for millennia.
The eradication of smallpox serves as a beacon of hope, demonstrating that with cooperation and funding, we can overcome even the most formidable challenges posed by infectious diseases.
