Başakşehir
Başakşehir is a municipality and district of Istanbul Province, Turkey. Its area is 107 km2, and its population is 514,900 (2022). It is in the European part of Istanbul.

History 
Former name of the area was Azatlık. The area specialized in providing gunpowder to the Ottoman army. Later a farm was established in place of Azatlık; the farm was known as Resneli farm referring to Resneli Niyazi, a military officer from Resen, North Macedonia (then a part of Ottoman Empire), who was a hero of Young Turk Revolution in 1908.

In 2008 the district Başakşehir was created from parts of the districts Küçükçekmece, Esenler and Büyükçekmece. The urban part of the new district, 10 neighbourhoods, was established as a municipality. At the 2013 Turkish local government reorganisation, the rural part of the district was integrated into the municipality, the villages becoming neighbourhoods.
