March 24 has witnessed moments that altered the course of medicine, politics, diplomacy and human rights. A single date produced a cure for the world’s deadliest disease, ended a presidency at gunpoint and sent a military alliance to war for the first time in its history. The events below span continents and centuries, each leaving a mark that still resonates today.
Canada Gives Black Citizens the Right to Vote – 1837
Upper Canada became the first British colony to grant Black men the right to vote in 1837. The decision arrived without fanfare but carried genuine constitutional weight. It predated similar rights in many parts of the world, including the United States, by several decades and stood as an early test of what democratic inclusion could actually mean in practice.
The First Long-Distance Telegram in India – 1855
The telegraph line between Agra and Calcutta, stretching over 1,300 kilometres, was formally opened on this day in 1855. It was a milestone in India’s communications history. The line connected two of the subcontinent’s most important cities and demonstrated the remarkable reach of Victorian-era technology.
The Eurydice Goes Down – 1878
HMS Eurydice, a Royal Navy training frigate, capsized and sank off the Isle of Wight in 1878. Around 300 sailors lost their lives. The vessel was caught in a sudden and violent snowstorm while returning from a training voyage to the West Indies. It remains one of Britain’s worst peacetime naval disasters and prompted a formal inquiry into the Navy’s handling of crew safety.
Koch Identifies the Tuberculosis Bacterium – 1882
German physician Robert Koch announced his discovery of Mycobacterium tuberculosis in Berlin in 1882. He identified the specific bacterium responsible for tuberculosis, a disease killing millions at the time. The announcement transformed medicine and firmly established the germ theory of disease. Koch received the Nobel Prize in Physiology or Medicine in 1905, in part for this work.
Mining Tragedy at Franklin, Washington – 1894
Thirty-seven miners were killed in a disaster at the Franklin coal mine in Washington State in 1894. The mine was operated by the Oregon Improvement Company and had a long record of safety complaints. The deaths intensified pressure on American legislators to introduce enforceable mining standards, a debate that would take years to resolve. It was one of the deadliest single mining incidents the Pacific Northwest had seen.
Britain Imposes Direct Rule on Northern Ireland – 1972
The British government suspended the Northern Ireland parliament at Stormont and imposed direct rule from Westminster in 1972. The move came amid escalating violence during the Troubles, following the events of Bloody Sunday in January that year. It was a turning point in British-Irish political relations that would shape the region for decades.
Military Coup Removes Isabel Perón in Argentina – 1976
Argentine President Isabel Martínez de Perón was overthrown in a military coup led by General Jorge Rafael Videla in 1976. The coup ended civilian rule and ushered in one of Latin America’s most brutal dictatorships. Thousands of people disappeared under the regime that followed. The junta remained in power until 1983, leaving a trauma that Argentine society continues to reckon with.
Indian Troops Complete Withdrawal from Sri Lanka – 1990
India’s military presence in Sri Lanka formally ended in 1990. Indian troops had been deployed under a 1987 peace accord to help disarm Tamil militants. The withdrawal concluded a troubled and costly intervention that had claimed over 1,000 Indian lives.
Tornado Kills 250 in Dantan, West Bengal – 1998
A powerful tornado tore through the town of Dantan in West Bengal in 1998. Around 250 people were killed and approximately 3,000 others sustained injuries. Entire neighbourhoods were flattened within minutes. It was among the deadliest tornado events recorded in eastern India and overwhelmed local emergency services for days afterwards.
NATO Launches Air Strikes Against Yugoslavia – 1999
NATO began a 78-day air campaign against Yugoslavia in 1999, targeting Serbian military positions during the Kosovo conflict. It was the first time the alliance had launched a sustained military offensive against a sovereign European nation. The strikes triggered considerable international debate about the limits of humanitarian intervention and reshaped how the world understood the use of collective military force outside a formal UN mandate.
