Freedonia (planet)

Freedonia was one of the many planets which provided troops for Morbius in his war against the alliance. (PDA: Warmonger)

The Doctor once claimed to William Shakespeare that Martha Jones was a citizen of the nation of "Freedonia", perhaps drawing inspiration for the name from this planet. (DW: The Shakespeare Code)

Behind the scenes
"Freedonia" is a generic name for a plausible-sounding but fictional country, popularised by the Marx Brothers film Duck Soup. Its use in The Shakespeare Code was intended as a reference to Duck Soup.
