For more than a hundred years, people in countries around the world have marked the 14th day of February as a time for lovers to give each other gifts and for children to write cards to each other and eat heart-shaped candy. But Valentine’s Day isn’t the only important event to occur on February 14th. There are many other anniversaries to mark on this day. Here are a few:

1400 – The death of King Richard II: The same English king whose engagement resulted in the first love poem mentioning Valentine’s Day (from court poet Geoffrey Chaucer) dies in prison in Pontefract Castle after his cousin Henry overthrows him. He probably starved to death, although another famous author, William Shakespeare, would portray his death as murder.

1859 – Hello, Oregon: The Oregon Country is admitted to the United States of America as the 33rd state.

1876 – Who invented the telephone? Alexander Graham Bell applied for a patent for his new invention, the telephone. Another inventor, Elisha Gray, applied the same day for a similar device, sparking a long controversy over who invented what first.

1912 – Hello, Arizona: Continuing the statehood tradition that Oregon established, the Territory of Arizona is admitted to the U.S. as the 48th state. Women were granted the right to vote in Arizona the same year, eight years before the rest of the nation.

1929 – The world’s most infamous mob hit: Unknown assailants shoot down seven people in Chicago, IL. Six of the dead are gangsters in the mob of Bugs Moran, an enemy of Al Capone in the business of selling Prohibition bootleg liquor. No one is ever arrested or charged for the crime—but there isn’t much doubt who masterminded it.

1931 – “I am… Dracula”: The most influential vampire movie ever made, and the start of Universal Studio’s famous monsters series, Dracula starring Bela Lugosi, premieres in theaters. Universal cannily uses Valentine’s Day to promote the film as “The Story of the Strangest Passion the World Has Ever Known!”

1961 – The Periodic Table becomes larger: The 103rd chemical element, Lawrencium, was discovered at the University of California. The name comes from the laboratory where it is synthesized, the Lawrence Berkeley National Laboratory.

2005 – Now it’s easy to watch funny animal videos: A group of college students launched a video-sharing website called YouTube.

Even if Valentine’s Day itself isn’t a major holiday for you, February 14th has many reasons to celebrate—unless you are a member of Bugs Moran’s gang or a supporter of Richard II. All of us at [company_name] would like to wish you a happy Valentine’s Day, however, you observe it.
