Transylvania is a historical region in Eastern Europe. Today it is part of Romania. Not much is known about Transylvania's association with the Muggle world, but it does have its own Quidditch team. The Transylvanian National Quidditch team's most glorious hour was during the running for the 1994 Quidditch World Cup, when the team beat the English National Quidditch team 390 to 10. However, they did not make it to the finals that year. It would seem in the wizard world Transylvania is an independent country from Romania.
