Sister cities of Hanover

Hanover or Hannover (German:  Hannover , [haˈnoːfɐ]), on the river Leine, is the capital of the federal state of Lower Saxony (Niedersachsen), Germany and was once by personal union the family seat of the Hanoverian Kings of Great Britain, under their title as the dukes of Brunswick-Lüneburg (later described as the Elector of Hanover). At the end of the Napoleonic Wars, the Electorate was enlarged to become the capital of the Kingdom of Hanover. In addition to being the capital of Lower Saxony, Hanover was the capital of the administrative area Regierungsbezirk Hannover (Hanover region) until Lower Saxony's administrative regions were disbanded at the beginning of 2005. Since 2001 it is part of the Hanover district (Region Hannover), which is a municipal body made up from the former district (Landkreis Hannover) and city of Hanover (note: although both Region and Landkreis are translated as district they are not the same).

With a population of 509,485 (31 December 2011) the city is a major centre of northern Germany, known for hosting annual commercial trade fairs such as the Hanover Fair and the CeBIT. Every year Hanover hosts the Schützenfest Hannover, the world's largest marksmen's festival, and the Oktoberfest Hannover, the second largest Oktoberfest in the world (beside Oktoberfest of Blumenau). In 2000, Hanover hosted the world fair Expo 2000. The Hanover fairground, due to numerous extensions, especially for the Expo 2000, is the largest in the world. Hanover is also of national importance because of its universities and medical school, its international airport, and its large zoo. The city is also a major crossing point of railway lines and highways (Autobahnen), connecting European main lines in east-west-direction (Berlin - Ruhr area) and north-south-direction (Hamburg - Munich et al.).
