TITLE: Seven Remarkable Moments in History - September 28

1. 48 BCE - Pompey the Great Is Assassinated

On September 28, 48 BCE, one of Rome's most celebrated generals met a tragic and ignoble end on the shores of Egypt. Pompey the Great, who had once been part of the First Triumvirate alongside Julius Caesar and Marcus Crassus, fled to Egypt after his devastating defeat at the Battle of Pharsalus. Seeking refuge with the young Pharaoh Ptolemy XIII, Pompey expected to find an ally.

Instead, Ptolemy's advisors calculated that Caesar's favor was more valuable than Pompey's gratitude. As Pompey's boat approached the shore, he was stabbed to death by men who had once served under him. When Caesar arrived in Egypt days later, he was presented with Pompey's severed head—a gesture meant to please but which reportedly moved Caesar to tears. This assassination marked a turning point in Roman history, effectively ending the Republic's last hope for a return to shared power and paving the way for Caesar's unchallenged dominance.

2. 1066 - William the Conqueror Lands in England

September 28, 1066 stands as one of the most consequential dates in English history. On this day, William, Duke of Normandy, landed at Pevensey Bay on England's southern coast with an invasion force of approximately 7,000 soldiers and cavalry. This landing set in motion the Norman Conquest, which would fundamentally transform England's language, culture, government, and social structure.

William had come to claim the English throne, which he believed had been promised to him by the late King Edward the Confessor. King Harold II, who had taken the crown, was forced to march his exhausted army south after just defeating a Norwegian invasion at Stamford Bridge. The two forces would meet at the Battle of Hastings on October 14, where Harold would fall and William would earn his epithet "the Conqueror." The Norman Conquest introduced feudalism, reshaped the English language with thousands of French words, and established a dynasty that would rule for generations.

3. 1542 - Juan Rodríguez Cabrillo Discovers California

On September 28, 1542, Spanish explorer Juan Rodríguez Cabrillo became the first European to set foot on what is now the west coast of the United States. Landing at a bay he named San Miguel (present-day San Diego), Cabrillo claimed the land for Spain and began a northward expedition that would map much of the California coastline.

Cabrillo, a Portuguese-born navigator sailing under the Spanish flag, was searching for the mythical Strait of Anián—a supposed water route connecting the Pacific and Atlantic oceans. Though he never found this passage, his voyage opened European awareness to the vast California territory. Cabrillo would die from complications of an injury suffered during the expedition in January 1543, but his legacy endures. California celebrates Cabrillo Day each September 28, and Cabrillo National Monument in San Diego commemorates his historic landing.

4. 1928 - Alexander Fleming Discovers Penicillin

September 28, 1928 marks one of medicine's most fortunate accidents. Scottish bacteriologist Alexander Fleming, returning to his laboratory at St. Mary's Hospital in London after a vacation, noticed something unusual in a petri dish he had left by an open window. A mold had contaminated his staphylococcus culture, but rather than simply discarding the ruined sample, Fleming observed that bacteria were not growing near the mold.

This serendipitous discovery would eventually revolutionize medicine. Fleming identified the mold as Penicillium notatum and named the antibacterial substance it produced "penicillin." Though it would take over a decade for Howard Florey and Ernst Boris Chain to develop methods for mass production, penicillin became the world's first widely-used antibiotic. It saved countless lives during World War II and earned Fleming, Florey, and Chain the 1945 Nobel Prize in Physiology or Medicine. This chance observation fundamentally changed how humanity fights infectious disease.

5. 1850 - The U.S. Navy Abolishes Flogging

On September 28, 1850, the United States Congress passed legislation abolishing the practice of flogging as punishment in the U.S. Navy. This reform marked a significant humanitarian milestone in American military history and came after decades of advocacy by reformers who considered the practice barbaric and counterproductive.

The movement to end naval flogging gained tremendous momentum from Herman Melville's semi-autobiographical novel "White-Jacket," published earlier that same year, which graphically described the brutality of shipboard flogging. The book galvanized public opinion and congressional action. While some naval officers argued that flogging was essential for maintaining discipline at sea, reformers countered that it degraded sailors and undermined rather than enhanced their loyalty and performance. The abolition represented a broader shift in attitudes toward punishment and human dignity that would influence military and civilian institutions throughout the following decades.

6. 1924 - First Round-the-World Flight Completed

September 28, 1924 witnessed a remarkable aviation achievement when two U.S. Army Air Service Douglas World Cruisers completed the first aerial circumnavigation of the globe. The aircraft, named "Chicago" and "New Orleans," touched down in Seattle, Washington, completing a journey of approximately 27,553 miles that had taken 175 days.

The expedition had begun on April 6, 1924, when four aircraft departed Seattle. The journey was fraught with challenges—mechanical failures, crashes, harsh weather, and the loss of two of the original aircraft along the way. Pilots and crews battled ice, fog, tropical heat, and primitive landing facilities as they hopped across the Pacific, through Asia, across Europe, over the Atlantic, and back across North America. The successful completion of this flight demonstrated aviation's potential for long-distance travel and international connection, capturing imaginations worldwide and paving the way for the future of global air travel.

7. 1978 - Pope John Paul I Dies Mysteriously

On September 28, 1978, Pope John Paul I was found dead in his bed, just 33 days after his election to the papacy—one of the shortest reigns in papal history. The sudden death of the 65-year-old pontiff, who had appeared in good health and good spirits, shocked the Catholic world and gave rise to enduring questions and conspiracy theories.

Known as "the Smiling Pope" for his warm, approachable demeanor, John Paul I had signaled his intent to reform the Vatican Bank and address other institutional concerns. The official cause of death was listed as a heart attack, but the Vatican's handling of the investigation—including the absence of an autopsy—fueled speculation that has persisted for decades. Some theorized foul play related to his reform agenda, while others attributed his death to the enormous stress of the position. His brief pontificate and mysterious death made him one of the most intriguing figures in modern Church history.


Reflecting on History's Tapestry

Looking at these seven events spanning over two millennia, we see how a single day on the calendar connects emperors and explorers, scientists and sailors, conquerors and popes. September 28 has witnessed endings and beginnings, accidents and assassinations, discoveries that saved millions and deaths that sparked mysteries.

History reminds us that we are part of an ongoing story. The decisions made on days like this one—whether by a young Egyptian pharaoh, a curious Scottish scientist, or a reform-minded pope—ripple forward through time to shape our present. As we mark another September 28, we add our own small chapters to this endless narrative, connected across centuries by the simple turning of the calendar.
