April 21: Holidays, Historical Events, Famous Birthdays & Zodiac Sign
According to ancient tradition, Romulus founded the city of Rome on April 21, 753 BC—an event still celebrated today as Natale di Roma.
About April 21
April 21 carries an unmistakable aura of beginnings and pivotal transitions. In ancient Rome, this date was honored with the Parilia festival, celebrating the city's legendary founding by Romulus in 753 BC. That same spirit of foundational change echoed across centuries: in 1509, Henry VIII took the English throne following his father's death, setting the stage for a transformative and tumultuous reign. Nearly three centuries later, King Buddha Yodfa Chulaloke established the city of Rattanakosin—known globally today as Bangkok—on the banks of the Chao Phraya River.
The date also witnessed decisive military turning points. In 1836, Texian forces under Sam Houston secured a stunning victory over General Santa Anna's troops at the Battle of San Jacinto, effectively clinching independence for the Republic of Texas. On a far darker note in 1918, Manfred von Richthofen—the famed World War I flying ace known as the "Red Baron"—was shot down and killed over Vaux-sur-Somme in France. Yet April 21 has also been a day of forward-looking milestones: in 1960, Brazil inaugurated its ambitious new capital, Brasília, officially transferring the seat of government from Rio de Janeiro.
Among the famous figures born on this day, few shine as brightly as Queen Elizabeth II, who arrived in 1926 and would go on to become the longest-reigning British monarch. She shares the date with a remarkable constellation of talent: the beloved Victorian novelist Charlotte Brontë, pioneering Scottish-American naturalist John Muir, and the influential German sociologist Max Weber. From the stage to the screen, entertainers like Iggy Pop, Patti LuPone, Tony Danza, Andie MacDowell, and James McAvoy all blew out their first candles on April 21, making it a truly star-studded birthday.
