The Soviet Red Army captured the city on April 1, 1945. Sopron, as part of Hungary, was ruled by a Socialist government. At this time many factories were built around Sopron. The Socialist government took away a lot of the freedom that people had. In August 1989, in Sopron there was a big protest against the Socialist government, which was called the "Pan-European Picnic". While this was happening more than 200 people who lived in East Germany (which was Socialist) escaped to the West. This was the beginning of a big change for all the Socialist countries of Europe. People who had not been allowed to travel or live in other countries were finally allowed to be free.
