About June 4

June 4 has a peculiar habit of marking turning points in human freedom and ingenuity. The day's most joyous leap came in 1784 when Élisabeth Thible, an opera singer, boarded a montgolfière above Lyon and became the first woman to fly in an untethered hot air balloon, reaching an estimated altitude of 1,500 metres. Just a year earlier, the Montgolfier brothers had publicly demonstrated their invention, and Thible's 45-minute flight proved the sky was no longer reserved for men. The spirit of breakthrough continued through the centuries: in 1896, Henry Ford completed and successfully test-drove his first gasoline-powered automobile, the Quadricycle, in a Detroit workshop.

The date also carries profound political weight. In 1919, the U.S. Congress approved the Nineteenth Amendment, guaranteeing women the right to vote, and sent it to the states for ratification. That same year, the first Pulitzer Prizes were awarded, recognizing excellence in biography, history, and journalism. Yet June 4 also remembers painful losses: in 1920, Hungary signed the Treaty of Trianon in Paris, losing 71% of its territory and 63% of its population — a day still observed as Trianon Treaty Day in Romania. Decades later, in 1989, the Tiananmen Square protests were violently suppressed in Beijing, an event now commemorated by international memorials on this date.

Amid the gravity, June 4 offers lighter observances too. It is National Cheese Day, a fitting tribute given that in 1411, King Charles VI of France granted the people of Roquefort-sur-Soulzon a monopoly for ripening their eponymous cheese — a privilege they had practiced for centuries and one that still protects Roquefort today. Tonga celebrates Emancipation Day, marking both the abolition of serfdom in 1862 and full independence from Britain in 1970. And in Finland, the Flag Day of the Finnish Defence Forces honors the birthday of C. G. E. Mannerheim, the marshal who led the nation through its most perilous hours.
