The "Zero-Year Curse"

So, our 9th president William Harrison wasn't exactly on the "Indians' side." He helped lead the US army during the War of 1812. Two of the Indian leaders were Tecumseh and his brother Tenskwatawa, aka "The Prophet."

One day when Tecumseh was away, Harrison attacked his brother's town, leaving Tenskwatawa dead. (The Battle of Tippecanoe)

From Wikipedia: "According to legend, Tecumseh had placed a "curse" on [William] Harrison, claiming that every President to be elected in a year ending with the number zero (which happens every 20 years) would die in office. Harrison, Lincoln (elected 1860), Garfield (elected 1880), McKinley (elected 1900), Harding (elected 1920), Roosevelt (elected 1940), and Kennedy (elected 1960) all died in office, falling prey to the Curse of Tecumseh, sometimes called the "zero-year curse". Ronald Reagan, elected in 1980, broke the curse, although some believe that after the assassination attempt by John Hinckley, Jr., he went into cardiac arrest and was resuscitated. George W. Bush, elected in 2000, has survived so far; his second term of presidency ends on January 20, 2009."
