 From 1933 to 1945, political interference from the Nazi regime limited and ultimately closed most Waldorf schools in Europe, with the exception of the British, Swiss, and some Dutch schools.The affected schools were reopened after the Second World War, though those in Soviet-dominated Eastern Germany were closed again a few years later by the Communist German Democratic Republic government.In North America, the number of Waldorf schools increased from nine in the United States and one in Canada in 1967 to around 200 in the United States and over 20 in Canada as of 2014.
