Bund der Vertriebenen
Steinbach joined the German Federation of Expellees in 1994. In May 1998 she was elected President of the organization, and was re-elected in 2000, 2002, 2004, 2006, 2008 and 2010. The Federation of Expellees claims to have 1.3 million members. This figure was disputed in January 2010 by the German news service DDP, which reported an actual membership of 550,000.
