What happened

The Potsdam Agreement awarded the northern portion of East Prussia, including the city of Königsberg, to the Soviet Union pending a final peace settlement that never occurred; the remainder went to Poland. Most of the prewar German population had already died or fled during the brutal Soviet advance of early 1945; the remnant, reduced by famine and disease under Soviet occupation, was formally expelled to Germany by 1947–48. The territory was renamed Kaliningrad in 1946 and resettled with Soviet citizens, becoming a militarized Russian exclave separated from the rest of the USSR/Russia by Lithuania and Poland.

Parties

The Soviet Union annexed the northern third of East Prussia around Königsberg under the Potsdam Agreement, later formally expelling the remaining German population and resettling the area with Soviet citizens.

Disputed

The permanence of the annexation, never confirmed by a final peace treaty, has periodically been questioned by some Western commentators, though it is broadly accepted in international practice as part of the postwar settlement; Germany does not press territorial claims.

The denominator

The 1939 German census gives roughly 1.1-1.2 million inhabitants for the districts later assigned to the Soviet Union, with Konigsberg itself at 372,000. Most fled or were evacuated ahead of the Red Army in the winter of 1944-45 or died in that flight; between about 100,000 and 140,000 Germans were still present when Soviet administration was established, and these were deported to the Soviet occupation zone of Germany in 1947-48.

The 100,000 counts only the formal expulsions of 1947-48; the far larger flight and evacuation of 1944-45, and the deaths during it, are not in the numerator.

On the death toll

Andreas Kossert puts 100,000-126,000 German civilians in Königsberg at the Soviet capture in April 1945 and finds only around 24,000 still present to be deported in 1947, with hunger accounting for about 75% of deaths, epidemics (chiefly typhus) 2.6% and violence 15%. The wide range reflects that an unknown share left rather than died; Soviet records show 102,407 Germans deported from the oblast to the Soviet zone of Germany between 1947 and 1951.

Documented forms of violence

Starvation and SiegeSexual ViolenceDestruction of Property

Kossert's study of Königsberg under Soviet administration and the wider East Prussian literature document mass starvation and typhus among the trapped civilian population, mass rape by Soviet troops during and after the storming of the city, and the destruction or requisition of German property before the 1947-48 deportations.
