Poland, which had not been an independent country for some time at that point, was recreated by the Allies in the Treaty of Versailles at the end of World War I in 1918. (PROSE: Timewyrm: Exodus) The Nazis saw it as a state created in a draconian treaty in order to punish the Germans. Many Germans lived in Poland (AUDIO: Just War) Prior to World War II, Adolf Hitler defied the Versailles Treaty by reoccupying the Rhineland. Winston Churchill thus grew fearful of Hitler's plans for Czechoslovakia, Poland and, in time, all of Europe. (PROSE: Players)

Before the outbreak of the war in September 1939, the Soviet Union signed a non-aggression pact with Nazi Germany. (AUDIO: An Eye For Murder) The pact stipulated that Poland be split between Germany and the USSR. Hitler hoped this would keep the Soviets off Germany's back but fully intended to attack them eventually. (PROSE: Timewyrm: Exodus)

When Germany invaded the country on 1 September 1939, an event which was recorded by the Matrix as being a part of the Web of Time, (AUDIO: Neverland) they effectively started the War. The Soviet Union also participated in the invasion, as per their previous agreement with Hitler. (PROSE: Timewyrm: Exodus) The invasion lasted a month. Brigadier Kraus gained a reputation during the invasion as the Butcher of Krakow. (PROSE: Illegal Alien) On 3 September 1939, the United Kingdom and Germany entered into a state of war because Adolf Hitler's Nazi government did not withdraw his troops from Poland.

21st century
In the 21st century, Poland joined the European Union (AUDIO: The Curse of the Fugue) and many Poles emigrated to the United Kingdom (TV: Day One) – like Trepper, who worked at the ATMOS factory (TV: The Sontaran Stratagem) or the family of Matteusz Andrzejewski, a student at the Coal Hill Academy. (TV: For Tonight We Might Die)

At some point in the 21st century, Poland was in economic crisis. Cities like Elbląg and Kalisz faced vast unemployment, with many people having limited access to such basic commodities as fresh water, food and petrol. Many Poles sought work in Eurozone countries such as the United Kingdom as illegal immigrants. Some of them, like Stefan Radek, were kidnapped and experimented upon by Alex Marlowe who tried to genetically engineer a new strain of Krynoid. (AUDIO: Hothouse)

In the 22nd century, the Wronsdehj conquered Poland, along with the Czech Republic, Austria, Germany, Italy and France. They were eventually defeated by the Fourth Doctor and Romana I. (PROSE: Life from Lifelessness)
