Leipzig is divided into ten boroughs or districts (Stadtbezirke).
The administrative division of Leipzig has been formed over the centuries since the town charter from 1156/70.
From 1889 onwards, many neighbouring municipalities were incorporated into the city of Leipzig to form a city of localities (Stadtteil).
As the city gradually incorporated new localities, its area increased.
After German reunification, the Leipzig authorities carried out a territorial reform in 1992, dividing the city into ten boroughs (Stadtbezirk) comprising 63 localities (Ortsteil).
