Blackadder traces the deeply cynical and self-serving lineage of various Edmund Blackadders throughout British history, from the muck of the Middle Ages to the frontline of The Great War.
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 six most evil men in the land to take the crown by force.
