  Two world wars and an economic depression dominated the first half of the 20th century. The First World War was fought between 1914 and 1918. It started when Archduke Franz Ferdinand of Austria was assassinated by the Yugoslav nationalist Gavrilo Princip. Most European nations were drawn into the war, which was fought between the Entente Powers (France, Belgium, Serbia, Portugal, Russia, the United Kingdom, and later Italy, Greece, Romania, and the United States) and the Central Powers (Austria-Hungary, Germany, Bulgaria, and the Ottoman Empire). The war left more than 16 million civilians and military dead. Over 60 million European soldiers were mobilised from 1914 to 1918.
  
  Russia was plunged into the Russian Revolution, which threw down the Tsarist monarchy and replaced it with the communist Soviet Union, leading also to the independence of many former Russian governorates, such as Finland, Estonia, Latvia and Lithuania, as new European countries. Austria-Hungary and the Ottoman Empire collapsed and broke up into separate nations, and many other nations had their borders redrawn. The Treaty of Versailles, which officially ended the First World War in 1919, was harsh towards Germany, upon whom it placed full responsibility for the war and imposed heavy sanctions. Excess deaths in Russia over the course of the First World War and the Russian Civil War (including the postwar famine) amounted to a combined total of 18 million. In 1932–1933, under Stalin 's leadership, confiscations of grain by the Soviet authorities contributed to the second Soviet famine which caused millions of deaths; surviving kulaks were persecuted and many sent to Gulags to do forced labour. Stalin was also responsible for the Great Purge of 1937–38 in which the NKVD executed 681,692 people; millions of people were deported and exiled to remote areas of the Soviet Union.
  
  The social revolutions sweeping through Russia also affected other European nations following The Great War: in 1919, with the Weimar Republic in Germany and the First Austrian Republic; in 1922, with Mussolini 's one-party fascist government in the Kingdom of Italy and in Atatürk 's Turkish Republic, adopting the Western alphabet and state secularism.Economic instability, caused in part by debts incurred in the First World War and 'loans' to Germany played havoc in Europe in the late 1920s and 1930s. This, and the Wall Street Crash of 1929, brought about the worldwide Great Depression. Helped by the economic crisis, social instability and the threat of communism, fascist movements developed throughout Europe placing Adolf Hitler in power of what became Nazi Germany.
  
  In 1933, Hitler became the leader of Germany and began to work towards his goal of building Greater Germany. Germany re-expanded and took back the Saarland and Rhineland in 1935 and 1936. In 1938, Austria became a part of Germany following the Anschluss. Following the Munich Agreement signed by Germany, France, the United Kingdom, and Italy, later in 1938 Germany annexed the Sudetenland, which was a part of Czechoslovakia inhabited by ethnic Germans. In early 1939, the remainder of Czechoslovakia was split into the Protectorate of Bohemia and Moravia, controlled by Germany and the Slovak Republic. At the time, the United Kingdom and France preferred a policy of appeasement.
  
  With tensions mounting between Germany and Poland over the future of Danzig, the Germans turned to the Soviets and signed the Molotov–Ribbentrop Pact, which allowed the Soviets to invade the Baltic states and parts of Poland and Romania. Germany invaded Poland on 1 September 1939, prompting France and the United Kingdom to declare war on Germany on 3 September, opening the European Theatre of the Second World War. The Soviet invasion of Poland started on 17 September and Poland fell soon thereafter. On 24 September, the Soviet Union attacked the Baltic countries and, on 30 November, Finland, the latter of which was followed by the devastating Winter War for the Red Army. The British hoped to land at Narvik and send troops to aid Finland, but their primary objective in the landing was to encircle Germany and cut the Germans off from Scandinavian resources. Around the same time, Germany moved troops into Denmark. The Phoney War continued.
  
  In May 1940, Germany attacked France through the Low Countries. France capitulated in June 1940. By August, Germany had begun a bombing offensive against the United Kingdom but failed to convince the Britons to give up. In 1941, Germany invaded the Soviet Union in Operation Barbarossa. On 7 December 1941 Japan 's attack on Pearl Harbor drew the United States into the conflict as allies of the British Empire, and other allied forces.
  
  After the staggering Battle of Stalingrad in 1943, the German offensive in the Soviet Union turned into a continual fallback. The Battle of Kursk, which involved the largest tank battle in history, was the last major German offensive on the Eastern Front. In June 1944, British and American forces invaded France in the D-Day landings, opening a new front against Germany. Berlin finally fell in 1945, ending the Second World War in Europe. The war was the largest and most destructive in human history, with 60 million dead across the world. More than 40 million people in Europe had died as a result of the Second World War, including between 11 and 17 million people who perished during the Holocaust. The Soviet Union lost around 27 million people (mostly civilians) during the war, about half of all Second World War casualties. By the end of the Second World War, Europe had more than 40 million refugees. Several post-war expulsions in Central and Eastern Europe displaced a total of about 20 million people.
  
  The First World War, and especially the Second World War, diminished the eminence of Western Europe in world affairs. After the Second World War the map of Europe was redrawn at the Yalta Conference and divided into two blocs, the Western countries and the communist Eastern bloc, separated by what was later called by Winston Churchill an " Iron Curtain ". The United States and Western Europe established the NATO alliance and, later, the Soviet Union and Central Europe established the Warsaw Pact. Particular hot spots after the Second World War were Berlin and Trieste, whereby the Free Territory of Trieste, founded in 1947 with the UN, was dissolved in 1954 and 1975, respectively. The Berlin blockade in 1948 and 1949 and the construction of the Berlin Wall in 1961 were one of the great international crises of the Cold War.
  
  The two new superpowers, the United States and the Soviet Union, became locked in a fifty-year-long Cold War, centred on nuclear proliferation. At the same time decolonisation, which had already started after the First World War, gradually resulted in the independence of most of the European colonies in Asia and Africa.
  
  In the 1980s the reforms of Mikhail Gorbachev and the Solidarity movement in Poland weakened the previously rigid communist system. The opening of the Iron Curtain at the Pan-European Picnic then set in motion a peaceful chain reaction, at the end of which the Eastern bloc, the Warsaw Pact and other communist states collapsed, and the Cold War ended. Germany was reunited, after the symbolic fall of the Berlin Wall in 1989 and the maps of Central and Eastern Europe were redrawn once more. This made old previously interrupted cultural and economic relationships possible, and previously isolated cities such as Berlin, Prague, Vienna, Budapest and Trieste were now again in the centre of Europe.
  
  European integration also grew after the Second World War. In 1949 the Council of Europe was founded, following a speech by Sir Winston Churchill, with the idea of unifying Europe to achieve common goals. It includes all European states except for Belarus, Russia, and Vatican City. The Treaty of Rome in 1957 established the European Economic Community between six Western European states with the goal of a unified economic policy and common market. In 1967 the EEC, European Coal and Steel Community, and Euratom formed the European Community, which in 1993 became the European Union. The EU established a parliament, court and central bank, and introduced the euro as a unified currency. Between 2004 and 2013, more Central European countries began joining, expanding the EU to 28 European countries and once more making Europe a major economical and political centre of power. However, the United Kingdom withdrew from the EU on 31 January 2020, as a result of a June 2016 referendum on EU membership. The Russo-Ukrainian conflict, which has been ongoing since 2014, steeply escalated when Russia launched a full-scale invasion of Ukraine on 24 February 2022, marking the largest humanitarian and refugee crisis in Europe since the Second World War and the Yugoslav Wars.
