April 6, 1199 — King Richard I of England dies

Richard I of England is one of its most legendary kings – better known in those legends as either “Richard the Lionheart”, and “Richard Coeur de Lion” – but probably also one of its worst. Of his ten year reign, he spent about six months (and none at all of his last five years) in England. He also spoke no English, despite being born there. He spent most of his reign fighting in the Crusades, and most of the remainder in his assorted French domains.

His death was from a gangrenous wound taken while trying to put down a rebellion in France. He left behind no direct heir, leading to England and France each being ruled by different claimants – his brother John in England (yes, THAT King John) and his nephew (via his other brother Geoffrey) Arthur in France. His legacy was one of warfare and loss, as neither claimant could conquer the entire territory that Richard has inherited.

April 6, 1936 — “Flash Gordon” premieres

Originating from a 1934 comic strip appearing in publications of the King Features Syndicate, Flash Gordon was one of Buck Rogers’ earliest competitors, and far and away his most successful. Flash Gordon was a blonde American hero who, with his love interest Dale Arden and scientist companion Dr Hans Zarkov, is transported to the planet Mongo. Here, Gordon comes into conflict with the dictator, Ming the Merciless, and encounters Ming’s many client states, slowly uniting them into a force that can overthrow the despot.

In 1936, Flash Gordon first his the silver screen. Episode one of a thirteen part serial premiered on April 6, starring Buster Crabbe as the title character. Since that time, there have been numerous sequels and revivals of the character, most notably the 1980 feature film of the same title that attempted to cash in on the popularity of Star Wars.
