The Federation of Expellees or Bund der Vertriebenen (BdV) is a non-profit organization formed on 27 October 1957 to represent the interests of German nationals of all ethnicities and foreign ethnic Germans (usually naturalised as German nationals after 1949) who either fled their homes in parts of Central and Eastern Europe, or were forcibly expelled following World War II, and their families.
Since 2014 the president of the Federation has been Bernd Fabritius, a Christian Social Union in Bavaria politician.
It is estimated that in the aftermath of World War II between 13 and 16 million ethnic Germans fled or were expelled from parts of Central and Eastern Europe, including the former eastern territories of Germany (parts of present-day Poland), the Czech Republic, Slovakia, Slovenia, Hungary, Croatia, Serbia (mostly from the Vojvodina region), the Kaliningrad Oblast of Russia (formerly the northern part of East Prussia), Lithuania, Romania and other East European countries.
The Federation of Expellees was formed on 27 October 1957. Before its founding, the Bund der Heimatvertriebenen (League of Expellees and Deprived of Rights), formed in 1950, represented the interests of displaced German expellees.
