Today in history July 21

  1. 356 BC – The Temple of Artemis at Ephesus, one of the Seven Wonders of the Ancient World, was destroyed by arson.
    The Temple of Artemis was a magnificent structure dedicated to the Greek goddess Artemis, located in the ancient city of Ephesus (modern-day Turkey). It was renowned for its grand scale and ornate sculptures, symbolizing the wealth and artistic achievements of the city. On the night of July 21, 356 BC, a man named Herostratus set fire to the temple in an attempt to achieve eternal fame. Ironically, the temple was destroyed, but Herostratus’s name was condemned to be forgotten, a punishment that was largely ignored by history. The temple was later rebuilt, but the original structure’s destruction marked a significant cultural and religious loss in the ancient world.
  2. 1861 – The First Battle of Bull Run (First Manassas) took place during the American Civil War.
    This was the first major land battle of the American Civil War and shattered the illusion that the conflict would be short and decisive. Union forces under Brigadier General Irvin McDowell engaged Confederate troops led by Brigadier General P.G.T. Beauregard near Manassas, Virginia. The battle was chaotic and marked by inexperience on both sides, but Confederate reinforcements eventually turned the tide. The Union army was forced into a disorganized retreat back to Washington, D.C., causing panic in the North. The Confederate victory boosted Southern morale and made it clear that the war would be longer and more brutal than initially expected.
  3. 1944 – The Battle of Guam began during World War II as American forces launched an assault to recapture the island from Japanese occupation.
    Guam, a strategically important island in the Pacific, had been under Japanese control since 1941. On July 21, 1944, American troops, primarily from the 3rd Marine Division, landed on the beaches of Guam in a massive amphibious assault. The battle was fierce and involved intense jungle warfare, with the Japanese defenders putting up strong resistance. After several weeks of fighting, American forces succeeded in liberating the island. The capture of Guam provided the Allies with a vital base for air operations and further assaults in the Pacific theater.
  4. 1969 – Apollo 11 astronauts Neil Armstrong and Buzz Aldrin became the first humans to walk on the Moon.
    Following the historic lunar landing on July 20, Neil Armstrong stepped onto the Moon’s surface, followed by Buzz Aldrin on July 21. Armstrong’s famous words, “That’s one small step for man, one giant leap for mankind,” marked a monumental achievement in human exploration. The astronauts spent about two and a half hours outside the lunar module collecting samples and conducting experiments. This event fulfilled President John F. Kennedy’s goal of landing a man on the Moon by the end of the 1960s. The Apollo 11 mission demonstrated the technological prowess of the United States during the Cold War space race.
  5. 356 AD – According to legend, the birth of Alexander the Great coincided with a significant event.
    Alexander the Great was born in Pella, the ancient capital of Macedonia, on July 21, 356 BC (some sources cite this date). His birth was said to be accompanied by omens and portents, such as the burning of the Temple of Artemis on the same day. Alexander would grow up to become one of history’s greatest military leaders, conquering a vast empire stretching from Greece to Egypt and into India. His tactics and leadership profoundly influenced military strategy and culture for centuries. The coincidence of his birth with the destruction of the temple was often interpreted as symbolic of the passing of an old era and the beginning of a new one under his reign.
  6. 1925 – The Scopes Trial began in Dayton, Tennessee.
    Also known as the “Monkey Trial,” this was a landmark legal case about the teaching of evolution in public schools. John T. Scopes, a high school teacher, was accused of violating Tennessee’s Butler Act by teaching Charles Darwin’s theory of evolution. The trial attracted national attention, pitting modernist and creationist views against each other. Clarence Darrow defended Scopes, while William Jennings Bryan argued for the prosecution. Although Scopes was found guilty and fined, the trial sparked a nationwide debate on science, religion, and education.
  7. 1947 – The United States Air Force was established as a separate branch of the U.S. military.
    Prior to this, air combat units were part of the U.S. Army Air Forces. The National Security Act of 1947 created the Air Force to address the increasing importance of air power in modern warfare. This change recognized the strategic necessity of air superiority and independent command structure. The establishment of the Air Force marked a significant reorganization of the U.S. military in the early Cold War period. The new branch would go on to play critical roles in Korean War, Vietnam War, and beyond.
  8. 1962 – The Mariner 1 spacecraft was launched by NASA but failed shortly after launch.
    Mariner 1 was intended to be the first spacecraft to fly by Venus and gather scientific data about the planet. However, shortly after liftoff, a guidance system malfunction caused the rocket to veer off course. The range safety officer ordered the destruction of the vehicle to prevent it from endangering populated areas. The failure was later attributed to a missing hyphen in the guidance computer’s code, highlighting the importance of precision in programming. Despite this setback, the Mariner program continued and successfully sent other probes to Venus and Mars.
  9. 1983 – Pioneer 10 became the first spacecraft to leave the solar system.
    Launched in 1972, Pioneer 10 was designed to study Jupiter and the outer solar system. After completing its primary mission, it continued traveling outward, sending back data as it ventured further into interstellar space. On July 21, 1983, it crossed beyond the orbit of Neptune, which was then considered the edge of the solar system. This marked a milestone in human space exploration, as Pioneer 10 became the first human-made object to enter interstellar space. Though contact was lost in 2003, the spacecraft’s journey paved the way for future deep-space missions.
  10. 2007 – The Treaty of Lisbon was signed by EU member states to reform the European Union’s structure.
    The treaty aimed to improve the efficiency and democratic legitimacy of the EU following the expansion to 27 member countries. It introduced changes such as a permanent President of the European Council and a new High Representative for Foreign Affairs. The treaty also streamlined decision-making processes and expanded the powers of the European Parliament. Signed on July 21, 2007, the treaty required ratification by all member states before coming into force in 2009. It remains a cornerstone of the EU’s legal and institutional framework.
