The Black Adder is the first series of the BBC sitcom Blackadder, written by Richard Curtis and Rowan Atkinson, directed by Martin Shardlow and produced by John Lloyd. The series was originally aired on BBC One from 15 June 1983 to 20 July 1983, and was a joint production with the Australian Seven Network. Set in 1485 at the end of the British Middle Ages, the series is written as a secret history which contends that King Richard III won the Battle of Bosworth Field, only to be unintentionally assassinated, and is succeeded by Richard IV, one of the Princes in the Tower. The series follows the exploits of Richard IV's unfavoured second son Edmund in his various attempts to increase his standing with his father and in the final episode his quest to overthrow him. Conceived while Atkinson and Curtis were working on Not the Nine O'Clock News, the series covers a number of medieval issues in Britain in a humorous and often anachronistic manner - witchcraft, Royal succession, European relations, the Crusades and the conflict between the Crown and the Church. The filming of the series was highly ambitious, with a large cast and much location shooting. The series also features Shakespearean dialogue, often adapted for comic effect.
After arriving late for the Battle of Bosworth Field, Edmund kills King Richard III (whom he thinks is stealing his horse) and secures the crown for his father.
With his father away at the Crusades, Edmund comes up with a plan to prove his brother is illegitimate, thus making him Prince Regent.
Edmund is appointed to the post of Archbishop of Canterbury after the king has the last one killed.
The King decides that Edmund should marry a Spanish Princess, who Edmund finds unattractive, in order to secure a treaty between Spain and England which will allow an invasion of France.
Percy and Baldrick are to be burned at the stake with Edmund, when he is accused of being a witch.
After the King takes away Edmund's title of Duke, he recruits the 6 most evil men in the land to take the crown by force.
