Inferno Earth Accessed via a power accident at the Inferno Project , the Third Doctor discovered a parallel universe where Great Britain was a republic governed by a fascist regime . Although some details were known about the history of this world , the Third Doctor personally experienced it only in the environs of its version of the Inferno Project . The Third Doctor described it as a " parallel space - time continuum " ( TV : " Inferno " ) whereas the Seventh Doctor called it an alternate timeline . ( PROSE : " " ) History . Creation . The Sixth Doctor believed the Inferno universe had only diverged from the primary reality about fifty years before he entered it , circa the 1970s . ( PROSE : " The Quantum Archangel " ) , although no incarnation of the Doctor was present when Marianne Kyle confirmed that the first known divergence was in the 19th century . When his conversation with his third incarnation ' s persona revealed the identity of this world ' s dictator , the Seventh Doctor wondered if the Timewyrm had any part in creating this timeline as part of her efforts to weaken him . ( PROSE : " " ) Another account speculated that the Inferno universe was the original timeline and the prime universe was a divergent timeline created by the Great Intelligence . ( PROSE : " Night of the Intelligence " ) . 19th century . The Confederate States of America won the American Civil War during the 1860s . In the war ' s aftermath , the American Confederation was established . ( PROSE : " The Face of the Enemy " ) 20th century . Joseph Stalin was the leader of White Russia ( PROSE : " The Face of the Enemy " ) and few Bolsheviks survived the Russian Civil War . ( PROSE : " The Schizoid Earth " ) Professor Edward Travers died in Tibet in 1935 , before ever seeing the Yeti . John Mackay survived the trip and later worked for the British Army . ( PROSE : " The Schizoid Earth " ) The Second World War never happened since Europe was divided into allied British and Russian spheres of influence , which were able to intimidate Adolf Hitler into backing down from his sabre - rattling . Meanwhile in Asia , the Japan ese successfully built their Asian Co - Prosperity Sphere . ( PROSE : " The Face of the Enemy " ) As a result of no war occurring , no equivalent of the Wellington bomber existed in this timeline and biplanes remained the standard fighters of the Republican Air Force into the early 1940s . ( PROSE : " The Schizoid Earth " ) The British Royal Family were executed for undisclosed reasons at an unknown date prior to 1943 . Brigade Leader Alastair Lethbridge - Stewart spoke about their deaths with relish . ( TV : " Inferno " ) After the execution of the Royal Family successive presidents drifted toward fascist ideology . ( PROSE : " The Schizoid Earth " ) In the 1950s , British military forces were allowed to establish bases in Germany and had weapon trades with Russia . The government was increasingly draconian and paranoid about spies coming in from America , Russia , or the Co - Prosperity Sphere - which was referred to as " the Chinese " in 1959 . No equivalent of the Korean War had happened . ( PROSE : " The Schizoid Earth " ) This world ' s James Lethbridge - Stewart would later suggest that it was the lack of a Second World War against Nazi Germany that had caused this : the British people had no recent warning of what could happen if they started giving up their freedoms and had no need or desire to fight for them . ( PROSE : " Night of the Intelligence " ) The Republic was surprised when the Alistair Gordon Lethbridge - Stewart of the regular Earth ' s 1969 accidentally ended up in their 1959 . They suspected him of being a spy and interrogated him for four months . By the time he ' d left , they ' d become aware of a third alternate Earth using their world as a staging ground to send warnings through time and the Republican Security Forces was proposed to deal with scientific threats . ( PROSE : " The Schizoid Earth " ) Shortly after its founding the RSF fought the Bannermen in Wales , where they reverse - engineered the alien technology . ( PROSE : " The Face of the Enemy " ) In the increasingly fascistic Republic , Elizabeth Shaw chose to join the Army instead of pursuing a scientific career after she left university and John Benton was trained to be harsh and sadistic . ( TV : " Inferno " ) Gordon Lethbridge - Stewart had become president by the late 1960s , disposing of even the pretence of liberal democracy . He even resorted to forcibly drugging the young people who had joined a state youth organisation called the Republic Youth Army in order to impose his will on them . James Lethbridge - Stewart was alienated by his father ' s thirst for power and used Axos material to get himself and his family out of this reality . ( PROSE : " Night of the Intelligence " ) The Great Intelligence launched an attack on Britain in this timeline as well . Koschei , here having not become the Master , saved the world from the Intelligence but was then captured , tortured , and pumped for information for years by the Security Forces . ( PROSE : " The Face of the Enemy " ) At some point , this universe ' s Doctor arrived on Earth . He took over the Republic of Great Britain and became its Leader . ( PROSE : " " ) He may have been responsible for some of the technological advances . ( PROSE : " The Face of the Enemy " ) Propaganda images of the Doctor abounded , including on posters with the slogan " UNITY IS STRENGTH " . ( TV : " Inferno " ) Near the end of the alternate Doctor ' s rule , in the 1970 s , the world was effectively ruled by the Conclave , a parallel of the United Nations Security Council , made up of the five main continents . The Conclave were based at Copernicus moon base to protect the delegates from attack and to intimidate subversive groups and enemy nations such as Australia . The reasoning was since the Moon could be seen from all parts of the civilised world it would serve as a reminder that the Conclave was watching . The powers were Russia , India , the American Confederation , the Asian Co - Prosperity Sphere , and Britain ( representing Europe ) . ( PROSE : " The Face of the Enemy " ) A parallel of UNIT was known as the European Axis Military Corps . ( PROSE : " Still Lives " ) In 1970 , the RSF were a parallels of contemporary British UNIT members : Brigade Leader Lethbridge - Stewart , Platoon Under Leader John Benton , and Section Leader Elizabeth Shaw , the latter having entered the military in this world . Eric Stahlman was carrying out a more advanced version of the Inferno Project . Australian Greg Sutton was a political prisoner in Britain , forced to assist Stahlman ' s project . ( TV : " Inferno " ) Shortly after the Doctor ' s unplanned arrival in this universe , an accident at Stahlman ' s project devastated the entire surface of the planet within thirty - nine hours . ( TV : " Inferno " ) The only survivors were those in bunkers , space station s and on the Moon . This world ' s Doctor was killed when the fallout from the disaster at Eastchester destroyed London . ( PROSE : " The Face of the Enemy " ) The Doctor had recognised the Leader ' s face was one of the regenerations he could have chosen at the trial . He would be haunted afterwards by the knowledge of what his alternate self had done . ( PROSE : " " ) While the Doctor and Jo were visiting Peladon , the surviving leaders of this Earth started to cross over to the Doctor ' s world . They planned to kill and replace their counterparts , but UNIT ( reluctantly working with the Master ) thwarted the plot . The Master allowed Marianne Kyle to escape , hoping she would cause trouble for the Doctor some day . ( PROSE : " The Face of the Enemy " )
