History
In 1938, Nazi Germany occupied Czechoslovakia. British Prime Minister Neville Chamberlain headed a conference intended to solve the resulting crisis but it proved ineffectual. (PROSE: Illegal Alien) In 1939, Hitler listed Czechoslovakia as one of the countries he had taken. (PROSE: Timewyrm: Exodus) In 1941, Nazi Colonel Oskar Steinmann claimed the occupation was welcomed because of the strength and unity offered by Fascism. (PROSE: Just War)

After her defection from the Soviet Union to the United Kingdom in 1958, the Czech scientist Nadia Červenka provided the Sen-Gen Facility with a neuro-chemical hallucinogen developed using a yellow fungus which was discovered in the Tunguska crater.

It was under the influence of the Soviet Union until 1989, when average people successfully campaigned for democratic rule. According to the Eleventh Doctor, the Czech communist government resigned between November and December 1989. The Doctor, Amy Pond and Rory Williams were present in Prague in November 1989 to witness the last gasps of that oppressive regime.

The Doctor claimed, however, that the fall of communism in Czechoslovakia was not at a fixed point in time, and so the time travelling trio had a genuine part to play in the success of democracy in the country in 1989.

In June 1990, free democratic elections were held in Czechoslovakia. (COMIC: The Broken Man)
