Greater Berlin Act in the context of "Boroughs and localities of Berlin"

Berlin is divided into boroughs or administrative districts (Verwaltungsbezirke). In Berlin, the term is officially shortened to Bezirke (districts). The boroughs are further divided into quarters (Ortsteile). These smaller localities are officially recognised, but have no administrative bodies of their own. Quarters and many of their subunits, the neighborhoods (Ortslagen), typically have strong identities that sometimes predate their inclusion into the modern boundaries of Berlin. Both the boroughs and the quarters function differently to other subdivisions in Germany due to Berlin's dual status as an independent city (kreisfreie Stadt) as well as a federated state of Germany (Land) in its own right.

Since 2001, Berlin has been made up of twelve boroughs, each with its own administrative body. However, because Berlin is a single municipality (Einheitsgemeinde), its boroughs have limited power, acting only as agencies of Berlin's state and city governments as laid out in the Greater Berlin Act of 1920. The boroughs are financially dependent on state donations, as they neither possess any taxation power nor own any property. This is in contrast to municipalities and counties in other German states, which are territorial corporations (Gebietskörperschaften) with autonomous functions and property.

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.

The Golden Twenties was a particular vibrant period in the history of Berlin. After the Greater Berlin Act, the city became the third largest municipality in the world and experienced its heyday as a major world city. It was known for its leadership roles in science, the humanities, art, music, film, architecture, higher education, government, diplomacy and industries.
