The Strandzha dialect is a dialect of the Bulgarian language, member of the Rup or Southeastern Bulgarian dialects. The present range of the dialect includes the Bulgarian part of Strandzha. In the past, the dialect was spoken on a much larger territory and extended far down into Eastern Thrace, now in Turkey. Following the Balkan wars, the Bulgarian population there was forced to flee to Bulgaria, settling mostly in the regions of Burgas and Varna in eastern Bulgaria.
