One of the most enduring mysteries is the “curse of Tecumseh,” which originated with the Native American warrior defeated by General William Henry Harrison. Since then, starting with Harrison, who was elected in 1840 and died just 31 days after taking office, almost every U.S. president elected in a year ending in zero has died in office:

Abraham Lincoln (1860) – assassination

James A. Garfield (1880) – assassination

William McKinley (1900) – assassination

Warren G. Harding (1920) – sudden death

Franklin D. Roosevelt (1940) – stroke

John F. Kennedy (1960) – assassination

Ronald Reagan (1980) was assassinated, and George W. Bush (2000) was nearly killed by a terrorist attack. This curse still makes many people shudder, although there is no scientific evidence to confirm the truth.

2. The mysterious death of Zachary Taylor
   President Zachary Taylor, elected in 1848, died suddenly in 1850 after drinking cold water and eating fruit. For decades, there was a theory that he was poisoned because he opposed the expansion of slavery. A 1991 exhumation was carried out to test for toxins – although the results showed low levels of arsenic, the suspicion never went away.
3. John F. Kennedy and the mysterious underground network
   The assassination of JFK in 1963 is perhaps the greatest political mystery of the 20th century. Although Lee Harvey Oswald was charged with firing three shots from the sixth floor of a Dallas bookstore, hundreds of different theories have emerged:

Was there a second shooter?

Was there a CIA involvement?

A connection to the mafia or Cuba? Many related documents have yet to be fully declassified, further raising public skepticism about the real truth.
