John F. Kennedy is the president that everyone knows. He was a rich man's son, an athlete, a war hero, a ladies' man, an author, a president - his face rendered forever young because the last time Americans saw him, he was riding in a convertible in Dallas, his glamorous wife at his side. Then the bullets struck, and the assassinated president became a legend, the truth of his life obscured by his tragic and untimely death. But JFK had more depth to his character than the magazine covers indicated.

Given how bad some of Rome's emperors were, it's a testament to just how insane and reviled Caligula was that he is still remembered, nearly 2,000 years later, as the epitome of everything that could be wrong with a tyrant. The Romans had high hopes for him after he succeeded Tiberius in AD 37, and by all accounts he was a noble and just ruler during his first few months in power. But after that, he suffered a mysterious illness that apparently rendered him insane. Indeed, the list of Caligula's strange actions is long.

Queen Elizabeth I was one of England's most influential rulers. Hers was an age when the arts, commerce, and trade flourished. It was the epoch of gallantry and great, enduring literature. It was also an age of wars and military conflicts. In the end, Queen Elizabeth I helped change the entire structure of female leadership and would go on to improve upon Henry VIII's successes.

Dred Scott was an unlikely candidate to become the impetus and rallying cry of a brand-new political party in the mid-19th century. He was sold to US Army doctor John Emerson in St. Louis, Missouri. Emerson's commission brought him to the Wisconsin Territory in 1836, which was free territory where slavery was illegal. By 1840, Dred Scott had married another slave of Emerson's, and the couple had a child. Desperate to shake off the yoke of slavery, Scott sued for his freedom in Missouri, arguing that once he had entered free territory he could no longer be a slave.
