What happened on April 8th? Major events in history
1525 – Treaty of Krakow and the birth of Prince Prussia
This is one of those moments that changed the map of Europe for centuries. King Sigismund I Old and Grand Master Albrecht Hohenzollern signed the Treaty of Krakow, ending the Prussian War and transforming the Prussian branch of the Teutonic Order into the secular, lenne Duchy of Prussia. The decision to secularize the Order was revolutionary – for the first time the great master paid tribute to Lenna to the Polish king as a secular prince. It is from this principality that power will grow over time, which will unite Germany and drag Europe into war three times.
1794 – Bartosz Głowacki receives the bulawa of the Ensign
A few days after the legendary Battle of Racławice, Tadeusz Kościuszko faced a unique task: to honour the heroes who fought the co-syndership against the Russian army. On 8 April, he appointed the peasant Bartosz Głowacki as the ensign of the grenadier regiment of Kraków. It was not just a gesture – it was a political and symbolic breach of state barriers in Poland. Głowacki, a simple cosynier, became an officer, which in the realities of the 18th century Republic was a real social revolution.
1861 – Massacre on Castle Square in Warsaw
That day in Warsaw's history was written in blood. During a demonstration in Castle Square, protesting the dissolution of the Municipal Delegation and the Agricultural Society, the Russian military opened fire on defenseless crowds. Over a hundred people died, several hundred were injured. This dramatic event became one of the sparks that ignited the January uprising two years later. Today, this massacre reminds us of how much Poles paid for every manifestation of freedom in the time of the partition.
1911 — Discovery of superconductiveness
On April 8, 1911, Dutch physicist Heike Kamerlingh-Onnes made a discovery that more than a hundred years later still fuels some of the world's most important technologies. He recorded the phenomenon of superconductiveness – a complete loss of electrical resistance in mercury chilled to extremely low temperature. For this discovery he received the Nobel Prize. Today, superconductivity is the foundation of MRI magnetic resonance, particle accelerators and, perhaps, the future of energy. It all started that day.
1919 – Establishment of AGH Academy in Kraków
Just a few months after Poland regained its independence, the reborn state took on building the foundations of modern science and industry. On 8 April 1919, the AGH University of Science and Technology was established in Kraków – a university that was to educate staff for Polish mining and metallurgy. Today AGH is one of the largest and best technical universities in Poland, employing thousands of scientists and educating tens of thousands of students. This historical calendar shows how quickly the young state wanted to catch up with civilization.
1940 – ORP "Earl" sinks "Rio de Janeiro"
In one of the bravest episodes of the Polish Navy during World War II, the Polish submarine ORP "Orzeł" sank in Norwegian waters a German transport ship "Rio de Janeiro", carrying on board Wermacht soldiers. About 200 of nearly 380 people on board died. This event was of great intelligence significance – it revealed that Germany was preparing an invasion of Norway, although the Allies failed to draw the right conclusions in time. The ORP "Orzeł" has been recorded in history as one of the symbols of the valor of Poles in a foreign country.
1973 – Death of Pablo Picasso
On April 8, 1973, the world of art lost one of its greatest Titans. Pablo Picasso, a Spaniard who revolutionized the painting of the 20th century, co-writer of cubism and author of "Guernica", left at the age of 91. He left more than 20,000 works – paintings, sculptures, ceramics and graphics. He was an artist who, throughout his life, refused to remain in one style, constantly redefining the boundaries of art. His death closed a certain era, although Picasso's influence on contemporary art continues to this day.
2005 – John Paul II funeral and opening of Wilson Square metro station
On the same day, April 8, 2005, Poland and the whole world experienced two very different moments, but in some way connected. The funeral of John Paul II, one of the most influential popes in the history of the Catholic Church, a Pole who changed the fate of Central Europe, was held in the Vatican. At the same time, Wilson Square Metro Station opened in Warsaw. Two symbols of two epochs, two faces of Poland – a spiritual and modernizing metropolis.
2022 – Rocket attack at the station in Kramatorsk
What happened that day in recent history still hurts and doesn't let you forget yourself. On 8 April 2022, during a full-scale Russian invasion of Ukraine, a Russian missile attack struck a railway station in Kramatorsk, through which civilians evacuated. 59 people died, more than 100 were injured. Among the victims were women and children waiting for evacuation trains. This day in history has become one of the most shocking symbols of war crimes committed during this invasion.
