The city has traditionally been a pole of attraction, and was a major centre for refugees from various ethnic backgrounds who immigrated to Anatolia from the Balkans during the loss of the Ottoman territories in Europe between the late 19th and early 20th centuries. The most recent arrival of Balkan Turks took place between the 1940s and 1990s, when the People's Republic of Bulgaria expelled approximately 150,000 Bulgarian Turks to Turkey. About one-third of these 150,000 Bulgarian Turkish refugees eventually settled in Bursa (especially in the Hürriyet neighborhood). With the construction of new industrial zones in the period between 1980 and 2000, many people from the eastern provinces of Turkey came and settled in Bursa.
