A Holy Day Morning Turned into Hell
On the morning of November 1, 1755, All Saints' Day, thousands of residents of Lisbon gathered in churches for worship. At that time, Lisbon was a commercial and imperial center of Portugal, a magnificent metropolis with stone buildings, palaces, and Baroque churches. However, around 9:40 am, the earth suddenly trembled with extraordinary force. The first earthquake lasted about three and a half minutes, enough to collapse major buildings and bury thousands of people under the rubble.
The tremors were followed by two smaller aftershocks, but the damage was already too severe. Churches filled with congregations collapsed, crushing those who were praying. Fires began to spread from the fallen kitchens, and within a few hours, a massive fire engulfed the city, destroying what remained.
Death Waves from the Atlantic Ocean
It was not just the earthquake that caused deaths. About 40 minutes after the first tremor, the seawater in the port of Lisbon receded suddenly, exposing the muddy seabed. People who survived the earthquake went down to the port area to find out what was happening. However, they did not realize that this was a sign of a greater danger.
Suddenly, a tsunami wave up to 6 to 12 meters high hit the coast of Lisbon, sweeping away thousands of people who had gathered on the cliffs. The waves also destroyed ships in the harbor and caused flooding in low-lying areas. This tsunami not only affected Portugal but also reached the coasts of Spain, North Africa, and even as far as the Caribbean, showing how powerful the energy released by the earthquake was.
Destruction and Surprising Death Toll
Lisbon, which was once one of the richest cities in Europe, was almost completely destroyed. It is estimated that between 30,000 and 50,000 people perished, out of a population of around 200,000. Legendary buildings such as the Ribeira Palace, the Royal Library, and many historic churches were destroyed. The prolonged fires for several days destroyed documents, artworks, and invaluable cultural treasures.
This disaster did not only affect the poor but also the nobility and royal family living in the palace. King José I and his family survived because they were outside the city at the time of the event. However, the trauma experienced by the king caused him to refuse to live in a walled building and instead built a tent on the hill of Ajuda.
Intellectual Revolution: Philosophy, Science, and Religion
The 1755 Lisbon earthquake became a turning point in European intellectual history. Before this disaster, many believed that the world was governed by a good God and that natural disasters were punishments for human sins. However, the devastating destruction of Lisbon, especially on a holy day, raised great doubts.
Famous philosopher Voltaire wrote the poem "Poème sur le désastre de Lisbonne" and later the novel "Candide," mocking Leibniz's idea that "everything is for the best in the best of all possible worlds." Instead, Voltaire questioned: why would a good God allow such suffering?
In the field of science, this earthquake spurred the development of modern seismology. Immanuel Kant, then a young philosopher, wrote several essays on earthquakes, suggesting the theory that earthquakes were caused by the movement of gases within the earth. This became the basis for scientific research on geological phenomena.
Rebuilding Lisbon: The Birth of Modern Urban Planning
After the disaster, the Portuguese Prime Minister, the Marquis of Pombal, took over leadership and implemented a revolutionary rebuilding plan. He ordered the construction of earthquake-resistant buildings with flexible wooden structures known as "gaiola pombalina." Streets in the Baixa Pombalina area were designed to be wider and straighter, and a modern drainage system was introduced.
This was one of the first examples of urban planning that considered the risk of natural disasters. Pombal also led a detailed investigation into all parishes about the effects of the earthquake, which was considered the first scientific study on earthquakes in history. This data helped future scientists understand earthquake and tsunami patterns.
Legacy and Lessons for the World
The 1755 Lisbon earthquake was not just a national tragedy; it was a global event that changed the way humans understood nature, God, and society. It showed that natural disasters are the result of the interaction between natural hazards and human vulnerability. At that time, weak buildings and lack of early warning systems caused large-scale deaths. Now, these lessons continue to guide us in building more resilient communities.
Today, Lisbon is a beautiful modern city, but its dark history remains etched in every corner. Monuments and museums remind us that nature can be both a friend and an enemy. Natural disasters cannot be avoided, but their impact can be reduced through preparation, science, and international cooperation. The Lisbon tragedy is an eternal reminder that we must always respect the power of nature and be ready to face the unexpected.
