When the Treaty of Berlin guaranteed Turkish property rights and restored southern Bulgaria to the Sultan's sovereignty at least 80,000 of the 150,000 Turkish émigrés had returned by September 1878. This caused enormous problems including housing the returning Turks whose property had been taken over by Bulgarians or destroyed. In September local authorities ordered that any houses taken over by Bulgarians were to be restored to their former owners on the latter's demand, whilst other returning Turks were given Tatar or Circassian land.
