Population of Czechia 1800-2020
A new nation
Following the First World War, the new republic of Czechoslovakia was formed, which included most of present-day Czechia and Slovakia, and smaller parts of their neighboring states. The region inherited a significant portion of its former-empire's industry, and emerged as a formidable and competitive economy in the newly-established Europe. Czechoslovakia was the only democracy in central or Eastern Europe throughout the inter-war years, and its politicians promoted relatively inclusive and progressive policies which contrasted the political attitudes of the former empire; in spite of this, dissent grew among non-Czechoslovak groups, particularly the German population which was supported by Hitler's Nazi Party. The Munich Agreement of 1938 (or "Munich Betrayal" as it is known in Czechia) saw Czechoslovakia's western allies allow Germany to annex the German-speaking Sudetenland region of Czechoslovakia, in order to prevent Hitler from launching a full-scale military invasion. Other non-Czech regions were also quick to secede or be annexed by neighboring countries, and Germany completely annexed Bohemia (which had lost much of its defensive capabilities with the loss of Sudetenland) less than a year after the Munich Agreement. It is estimated that Czechoslovakia suffered almost 350,000 fatalities during the war, and approximately eighty percent of these were Jews murdered during the Holocaust.Between 1940 and 1947, the population of present-day Czechia dropped from 11.2 million people to below 8.8 million; while a significant portion of this decline was made up by the fatalities suffered during the war and Holocaust, the largest decline was a result of the mass-expulsion of ethnic Germans in 1945 and 1946. It is estimated that as many as 800,000 Germans were forcefully expelled from the Czech lands in the summer of 1945, and several thousand died during these mass expulsions. Almost 2.5 million Germans were removed from Czechoslovakia in the 18 months after the war, as part of the Beneš decrees, which continue to be a controversial topic in Czechia to this day.
