Beylikdüzü is a district in the European suburbs of Istanbul, Turkey, located north of the Sea Of Marmara, south of Esenyurt, east of Büyükçekmece, and west of Avcılar. It is assumed that Beylikdüzü was first settled by Greeks from Byzantion in the second century AD as a farming village. It later became a popular resort for residents of Constantiople in the Byzantine Empire, a status that continued after the Fall of Constantinople to the Ottoman Empire. The region was referred to as "Garden" in the later Ottoman period, and following the foundation of the Turkish Republic was called "Kavaklı," after the large number of poplar trees, a name which was used until 2003. The modern name means "Plains of the Beylik."
The slum districts common in much of Istanbul are rarer in Beylikdüzü, where a survey by the municipal council indicated that 40% of residents have a university degree. Beylikdüzu together with the Ataköy Marina district are now attracting the upper-middle class because of their good infrastructure, and are seeing the construction of new luxury developments. The attraction is also increased by their close proximity to the Istanbul Atatürk Airport. Beylikdüzü is home to the most shopping malls in Istanbul and is considered a heaven for shopping, also referred to as the "AVM cumhuriyeti" (or republic of shopping in English).
