Selected Events
Dutch East India Company Founded
In the early 17th century, the Dutch Republic sought to challenge Portuguese and Spanish dominance in the lucrative Asian spice trade amid its ongoing struggle for independence from Spain. Several smaller trading ventures had already explored routes to the East Indies, but competition and high risks prompted consolidation. On March 20, 1602, the States General of the Netherlands granted a 21-year charter merging these companies into the Vereenigde Oostindische Compagnie, or VOC. The new entity received monopoly rights on Dutch trade east of the Cape of Good Hope, along with authority to wage war, negotiate treaties, and establish colonies. Shares were sold publicly, creating one of the world's first joint-stock companies with tradable ownership on the Amsterdam exchange. The VOC quickly built a vast network of trading posts and naval power that dominated European commerce with Asia for decades.
Why it matters: The VOC pioneered the corporate structure still used by modern multinationals and financed Dutch global expansion that reshaped trade routes and colonial empires in Asia. Its model influenced subsequent companies like the English East India Company and established precedents for state-backed commercial imperialism lasting into the 19th century.
Napoleon Enters Paris to Begin Hundred Days
Following his abdication in 1814 and exile to Elba, Napoleon Bonaparte escaped in late February 1815 with a small force and landed near Cannes on March 1. As he marched north, French troops sent to oppose him defected en masse, swelling his ranks dramatically. King Louis XVIII fled the capital on March 13. On March 20, Napoleon arrived in Paris amid jubilant crowds and reclaimed power, launching the period known as the Hundred Days. He immediately began reorganizing the government and army while promising constitutional reforms to broaden support. European powers, already gathered at the Congress of Vienna, swiftly formed a new coalition against him.
Why it matters: The return triggered the final coalition war that ended at Waterloo in June, leading to Napoleon's second abdication and permanent exile on Saint Helena. It reshaped the post-Napoleonic European order through the Congress of Vienna settlements and reinforced the principle of monarchical restoration across the continent.
Uncle Tom's Cabin Published as Novel
Harriet Beecher Stowe, an American author and abolitionist, had serialized her antislavery story in the National Era newspaper starting in 1851. Drawing on real accounts of enslaved people's experiences and the Fugitive Slave Act's injustices, she crafted a narrative centered on the devout slave Uncle Tom and other characters facing separation and cruelty. On March 20, 1852, the complete novel appeared in book form from Boston publisher John P. Jewett. It sold hundreds of thousands of copies rapidly in the United States and Britain, becoming a publishing phenomenon second only to the Bible in popularity at the time. The work humanized the suffering under slavery for Northern readers previously ambivalent about the institution.
Why it matters: The novel intensified sectional tensions leading to the American Civil War and helped shift public opinion toward abolitionism. Its cultural impact endured through stage adaptations, translations, and ongoing debates about its portrayals, influencing American literature and civil rights discourse for generations.
Einstein Submits General Theory of Relativity Paper
Albert Einstein had developed special relativity a decade earlier but struggled to extend it to gravity and accelerated frames. Building on mathematical work by colleagues including Marcel Grossmann and David Hilbert, he formulated a geometric theory of gravity using curved spacetime. On March 20, 1916, Einstein submitted the foundational paper "The Foundation of the General Theory of Relativity" to the journal Annalen der Physik. The work presented the Einstein field equations describing how matter and energy curve spacetime, predicting phenomena like gravitational lensing and the bending of starlight during solar eclipses. It marked the culmination of years of intense effort amid World War I disruptions in Europe.
Why it matters: The theory revolutionized physics, replacing Newtonian gravity and enabling predictions confirmed by observations such as the 1919 eclipse expedition. It underpins modern cosmology, GPS technology, and black hole research, fundamentally altering humanity's understanding of the universe's structure.
Aum Shinrikyo Sarin Attack on Tokyo Subway
The Japanese doomsday cult Aum Shinrikyo, led by Shoko Asahara, had been preparing chemical weapons amid apocalyptic beliefs and conflicts with authorities. On the morning of March 20, 1995, during rush hour, five cult members punctured plastic bags containing liquid sarin on multiple Tokyo subway lines. The nerve agent quickly vaporized, killing 14 people and injuring thousands more who suffered respiratory failure and neurological damage. Japanese police launched a massive investigation that led to arrests of cult leaders and members. The attack exposed vulnerabilities in urban infrastructure and prompted global scrutiny of religious extremism and weapons proliferation.
Why it matters: It remains one of the deadliest terrorist attacks using chemical weapons in a major city, spurring international conventions on chemical weapons and domestic security reforms in Japan. The event highlighted risks of non-state actors acquiring weapons of mass destruction and influenced counterterrorism strategies worldwide.
US-Led Coalition Invades Iraq
Tensions had escalated after the September 11 attacks as the United States accused Iraq under Saddam Hussein of possessing weapons of mass destruction and supporting terrorism. A coalition including the UK, Australia, and Poland prepared military action despite lacking full UN Security Council approval. On March 20, 2003, coalition forces launched airstrikes and a ground invasion from Kuwait, rapidly advancing toward Baghdad. Iraqi resistance varied, but major cities fell within weeks. The operation, codenamed Iraqi Freedom, marked the start of a prolonged conflict that toppled the Ba'athist regime.
Why it matters: The invasion led to the removal of Saddam Hussein but sparked years of insurgency, sectarian violence, and debates over intelligence failures and international law. It reshaped Middle East geopolitics, influenced global views on preemptive war, and contributed to long-term instability in Iraq and the broader region.
