In the aftermath of the Hungarian Revolution of 1956, 200,000 Hungarians fled to Austria as refugees. Many of these Hungarians would go on to live in Canada, the United States and Australia. Mass arrests and denunciations continued for months after the end of the revolution. Hundreds of Hungarians were executed by the communist authorities. Hundreds more were deported to the Soviet Union, many without evidence. The Hungarians who fled after the revolution, built strong communities in the west. They built churches, schools and community centres to keep their Hungarian heritage alive.
