Today in 1422, Henry the Sixth became the King of England at the ripe old age of eight months when his 35-year-old father, Henry the Fifth, died unexpectedly.
A quick biography from Wikipedia:
Henry VI (6 December 1421 – 21 May 1471) was King of England from 1422 to 1461 and again from 1470 to 1471, and disputed King of France from 1422 to 1453. Until 1437, his realm was governed by regents. Contemporaneous accounts described him as peaceful and pious. His periods of insanity and his inherent benevolence eventually led to his own downfall, the collapse of the House of Lancaster, and the rise of the House of York.
An interesting note from Wikipedia:
Unlike murderers of lesser fame, there is no waxwork figure of Jack the Ripper at Madame Tussauds' Chamber of Horrors, in accordance with their policy of not modelling persons whose likeness is unknown. He is instead depicted as a shadow. In 2006, Jack the Ripper was selected by BBC History magazine and its readers as the worst Briton in history.
The last one I'm going to mention is perhaps the most famous. In 1997 Princess Diana was killed in a car accident in Paris. A lot of controversy has surrounded the accident and Diana's death, but it was determined in court in 2008 that the drunken driver was solely to blame.
