1306: The Murder That Ended the Premysl Dynasty

On 4 August 1306, Bohemian King Wenceslas III was stabbed to death in Olomouc, cutting short the reign of a young ruler who had held the crowns of Hungary, Bohemia, and Poland. He was just 16 years old. His death extinguished the male line of the Premysl dynasty, a royal house that had shaped Central Europe since the ninth century.

With no male heir, the dynasty that had produced kings across three kingdoms collapsed in a single moment of violence. The Luxembourg clan seized Bohemia; the Piasts took Poland. The age of Premyslid rule was over.

1546: Scholar and Printer Etienne Dolet Hanged and Burned for Heresy in Paris

Etienne Dolet, born in Orleans in 1509, was a French scholar, translator and printer whose humanist convictions put him on a collision course with the French Inquisition. Educated at Padua and Toulouse, he built a reputation as a gifted orator and a defiant critic of religious orthodoxy. His publications in Lyon drew the close attention of inquisitorial authorities, and after several periods of imprisonment, the combined forces of the parlement of Paris, the Inquisition, and the Sorbonne secured his conviction for heresy, blasphemy and sedition.

On 3 August 1546, his 37th birthday, Dolet was hanged and burned alongside his books on the Place Maubert in Paris. He is remembered today as a martyr for freedom of speech and freedom of the press.

1807: Aaron Burr on Trial for Plotting the Secession of New England

Aaron Burr, former Vice President of the United States, stood trial beginning 3 August 1807, accused of conspiring to engineer the secession of New England and carve out an independent empire in the American west. The charges grew from years of suspicion surrounding his political ambitions and alleged dealings with foreign powers after his catastrophic fall from grace following the fatal duel with Alexander Hamilton in 1804.

The trial, presided over by Chief Justice John Marshall in Richmond, Virginia, became one of the most closely watched legal proceedings in early American history. Burr was ultimately acquitted on the treason charge, Marshall ruling that the prosecution had failed to prove an overt act of treason as required by the Constitution.

1916: Knighted Diplomat Hanged for Treason After Failed Easter Rising Mission

Sir Roger Casement, the British consul who had been honoured for exposing colonial atrocities in the Congo and Peru, was hanged at Pentonville Prison in London on 3 August 1916. Once celebrated as the 'father of twentieth-century human rights investigations', he had spent the war years seeking German military support for the Easter Rising before being arrested on the Kerry coast just days before the uprising began.

Stripped of his knighthood, he was tried and convicted of high treason. During and after the trial, British intelligence circulated typescripts of private journals, said to be in Casement's hand, that detailed homosexual activity. The material, illegal under the laws of the time, was used to undermine calls for clemency. He was executed at 49, and the authenticity of those diaries has been disputed by scholars ever since.
