Neukölln (German: [nɔʏˈkœln] ; officially abbreviated Neuk), is one of the twelve boroughs of Berlin. It is located south-east of Berlin's center and stretches from the inner city southward to the border with Brandenburg, encompassing the eponymous quarter of Neukölln in the north, and the southern quarters of Britz, Gropiusstadt, Buckow and Rudow.
The borough was constituted in 1920, when the Greater Berlin Act came into effect. After World War II, Neukölln was part of the American sector during the Allied occupation of the city, and of West Berlin from 1949 until German reunification in 1990. Since the late 1950s, it has been characterised by one of the highest shares of immigrant residents in Berlin, especially in its urbanized and industrialized northern regions. An influx of students and artists since the mid-2000s has led to gentrification.
