POTSDAM CONFERENCE TO REDRAW EUROPE’S BORDERS

Berlin Suburb of Potsdam, Germany July 17, 1945

After Nazi Germany’s fuehrer (leader) Adolf Hitler committed sui­cide on April 30, 1945; and after Hitler’s polit­ical suc­ces­sor Reich Presi­dent Grand Admiral Karl Doenitz agreed to the uncon­di­tional sur­render of all German armed forces on May 7 and 8, 1945; and after Gen. Dwight D. Eisen­hower, Supreme Com­man­der Allied Expedi­tionary Force, dis­solved Doenitz’s govern­ment on May 23; and after Allied repre­sen­ta­tives placed German gover­nance under the author­ity of the Allied Mili­tary Occu­pa­tion Govern­ment on June 5, it was time for the world’s top 3 states­men and their chief civil­ian and mil­itary advi­sors to meet face to face to nego­ti­ate a just and lasting peace under which a new Europe could emerge.

That meeting, the third between a U.S. President but the first between Harry S. Tru­man, British Prime Minis­ters Win­ston Chur­chill and his successor Clement Att­lee, and Soviet Pre­mier Joseph Stalin, got under­way on this date, July 17, 1945, in Berlin’s rela­tively undamaged, picture-post­card suburbs of Pots­dam and Babels­berg, tempo­rar­ily absent their local citi­zenry. Among the agenda items pushed by the planners of the Pots­dam Con­fer­ence (code­named Termi­nal) was the estab­lish­ment of a new post­war order that would rectify the defects of the past 3 decades. Since the Big Three’s last meeting in Yalta, Soviet Crimea, 5 months earlier, Stalin’s armies had over­run the 3 Baltic States, Poland, Czecho­slo­va­kia (today’s Czech Repub­lic and Slo­va­kia), Hun­gary, Roma­nia, Bul­garia, and half of pre­war Germany (Central [now Eastern] Germany, East and West Prussia, Pomer­ania, and Upper and Lower Silesia). The Western Allies had helped expel Hitler’s armies from Norway, Den­mark, the Nether­lands, Bel­gium, and Italy. (France had been liber­ated the year before.) The victors had divided Germany and Austria into 4 occu­pa­tion zones each. Thus Europe was roughly divided longi­tu­dinally through Central Europe, with Western demo­cratic regimes planted in the West and Soviet-style satellite regimes in the East.

Early in their discussions in Potsdam the Big Three faced up to a mili­tary fait accom­pli by accepting the bifur­ca­tion of Europe into West and East. The issue of estab­lishing new national borders in Central and Eastern Europe based largely on ethnic homo­geneity, how­ever, domi­nated what came next, espe­cially as it affected Poland and neigh­boring Germany. Nazi Germany’s annex­a­tions in the East were reversed, and the country’s eastern border was shifted west­wards to the Oder and Neisse Rivers, effec­tively reducing pre­war Germany in size by close to 25 per­cent (see map below), while over 28,000 sq. miles/­72,520 sq. kilo­meters of Eastern Poland were annexed by the Soviet Union, today forming western Lithu­a­nia, Belarus, and Ukraine (not shown in map). German popu­la­tions in newly con­figured Poland, Czecho­slo­va­kia, Hungary, and the Soviet Union were to be expelled from their ancestral homelands “in an orderly and humane manner.”

The orderly and humane expulsion of alien nationals never happened. The crea­tion by the 3 victo­rious powers of eth­nically homo­ge­neous nation states in Central and Eastern Europe, in which every nation state would sup­posedly have and live within defen­sible borders, gave rise to an appalling series of forced popu­la­tion trans­fers and resettle­ments (we know them today as “eth­nic clean­sing”), not just of ethnic Germans, but of Eastern Poles, Hun­garians, Roma­nians, Ukrai­nians, and others who after the war found them­selves out­side the borders of their recon­figured home states. The largest single ethnic popu­lation up­heaval in Euro­pean his­tory dis­placed more than 20 mil­lion people in total, of which between 12 and 14 mil­lion were German citi­zens and foreign ethnic Germans. During the up­heaval over 2 mil­lion civil­ians, mostly women and chil­dren, died from hunger, dis­ease, and vio­lence; indeed, 10–30 percent of those affected were killed.

Potsdam Conference aftermath: Germany’s postwar territorial losses

Above: With the stroke of a pen all prewar German terri­tories east of the dark blue north-south Oder-Neisse line—com­prising nearly one quarter (23.8 per­cent) of the coun­try—were severed from those to the west under border changes promul­gated at the Pots­dam Con­fer­ence (July 17 to August 2, 1945). The dark yellow region (called the Poland Admin­is­tra­tive Area by the Soviets) and the gray region encom­passing the port city of Danzig—both regions popu­lated almost exclu­sively by Germans—became part of post­war Poland. The rust-colored remain­der, con­sisting of northern East Prussia with the large German city and ice-free port of Koenigs­berg (now renamed Kalinin­grad), was allo­cated to the Soviet Union as the Kalinin­grad Ob­last of today’s Russia even though it sat in ethni­cally Polish and Lithu­anian terri­tory. Nearly all ethnic Germans in these reshuffled terri­tories of Central and Eastern Europe—esti­mated at roughly 12 mil­lion as of autumn 1944—fled west on foot or by avail­able trans­port or were later forcibly expelled, adding another 2 mil­lion impov­er­ished and dis­placed persons (DPs) to this fran­tic exodus of frightened men, women, and chil­dren. On July 21 at Potsdam Stalin told Truman and Chur­chill: “There are no Germans left [east of the Oder-Neisse].” Truman sought clari­fi­ca­tion: “Where are the nine million Germans?” Stalin shrugged, “They have fled.” Another 7.8 mil­lion DPs in Germany had been invol­un­tary foreign laborers and recently released in­mates from pris­oner of war and death camps. Over 2 mil­lion DPs, mostly women and chil­dren, perished from dis­ease or star­va­tion or were killed in revenge-driven ethnic cleansing (10–30 per­cent) during this mass migra­tion of more than 20 million people, of which 13.5 million were Germans and upwards of 4 mil­lion were Poles uprooted from areas that became parts of the Soviet Socialist Republics of Lithuania, Belorussia (Belarus), and Ukraine. Such was the price of peace.

During the war the Czecho­slo­vak govern­ment-in-exile pursued a 2‑fold policy: (1) restore Czecho­slo­vakia to its pre-1938 (pre-Munich) boun­daries and (2) remove or at least reduce, through a com­bi­nation of minor border recti­fi­ca­tions and popu­la­tion trans­fers, the state’s German and Hun­garian minori­ties in order to restore the terri­torial integ­rity of Czecho­slo­vakia, estab­lish greater national homo­ge­neity, and reduce the poten­tial risk of their becoming fifth colum­nists. Czecho­slo­vak presi­dent Eduard Beneš, in a May 19, 1945, decree labeled the 3 million ethnic Germans and Hun­ga­rians “unre­li­able for the state,” meaning trai­tor­ous citi­zens based on war­time Nazi acti­vi­ties, clearing the way for nation­wide con­fis­ca­tions and expul­sions of people who found themselves on the wrong side of the Czecho­slo­vak border.

The widely expressed urge to create ethni­cally homo­geneous nation states in Central and East­ern Europe was pre­sented as the key rea­son for the offi­cial deci­sions of the 1945 Pots­dam and pre­vious Allied con­fer­ences as well as the resulting expul­sions of alien resi­dents. Presi­dent Frank­lin D. Roose­velt called forced popu­la­tion trans­fer mea­sures “harsh” but accept­able if they were “the only way to main­tain peace” between quar­reling eth­nic­ities. Prime Minis­ter Chur­chill agreed. But the wrinkle was this: With so many national borders shifting or having shifted, to which coun­tries should these refugees and dis­placed per­sons be repa­tri­ated? Was it ever jus­ti­fied, for example, for non- and anti­-com­munist refugees to be repa­tri­ated against their will to coun­tries under Soviet domi­na­tion perhaps to suffer false arrest, arbi­trary imprison­ment, or a worse fate? And what about Jewish sur­vi­vors of the Holocaust? Presi­dent Truman took a cru­cial step of ordering that Jews be iden­ti­fied and regis­tered as Jews, not by their pre­war nation­ality. The cold reality was, first, some Euro­pean states wanted neither the Jews they had nor their Jews to return, and, secondly, Euro­pean Jews had no state of their own to offer them asylum before the state of Israel was estab­lished in May 1948 on ter­mi­na­tion of the British mandate of Palestine.

By the end of the war in Europe an esti­mated 5.6 mil­lion ethnic Germans had fled their homes in the East, up from 3.5 mil­lion in January 1945, often with nothing but the clothes on their back and what they could carry. Poles believed the expul­sion of Germans from post­war Poland would avoid future atro­cities like those the Nazis had in­flicted on their popu­la­tion during the war. Polish autho­ri­ties in exile abroad pro­posed a popu­la­tion trans­fer of Germans as early as 1941. During the war the Polish govern­ment-in-exile and the Czecho­slo­vak govern­ment-in-exile, both located in England, worked toward making this happen as soon as Nazi Germany was defeated. The 1923 Treaty of Lausanne had set such a prece­dent when 1.5 mil­lion ethnic Greeks from Turkey and 500,000 Muslims from Greece had been forcibly removed and resettled.

The post­war Polish and Czecho­slo­vak govern­ments charac­ter­ized the forced exile and con­fis­cation of expellees’ pro­perty as “a just punish­ment for Nazi crimes.”

The expul­sion of ethnic Germans from areas out­side the redrawn borders of post-Nazi Germany created major social dis­rup­tions in the receiving German states (Laender). The states were hard pressed to pro­vide mil­lions of new resi­dents with decent housing, schooling, employ­ment, and finan­cial assis­tance. An esti­mate from the year 2000 suggested that as many as 20 per­cent of Germany’s 80 mil­lion citizens were expellees and their descendants.
