Hamburg-Altona (DE)
Altona is the westernmost urban borough (Bezirk) of the German city state of Hamburg, on the right bank of the Elbe river. From 1640 to 1864 Altona was under the administration of the Danish monarchy. Altona was an independent borough until 1937. In 2016 the population was 270,263.
In 1871 Altona became a part of the German Empire. In the same year the town was hit by cholera, with a minimum of 16 casualties in Altona.[4]
During the Weimar era following World War I, the town of Altona was disturbed by major labor strikes and street disorders. Inflation in Germany was a major problem. In 1923 Max Brauer, the mayor of Altona, directed that town personnel should be paid in part with gas meter tokens, as the tokens did not lose value from inflation. The most notable event at that time was the Altona Bloody Sunday (German: Altonaer Blutsonntag) on 17 July 1932, when several people were shot by the police force which was providing security for a demonstration by Nazi groups. After police raids and a special court, on 1 August 1933, Bruno Tesch and others were found guilty and put to death by beheading with a hand-held axe. In the 1990s, the Federal Republic of Germany reversed the convictions of Tesch and the other men who were put to death, clearing their names.
In 1938 The Greater Hamburg Act removed Altona from the Free State of Prussia in 1937 and merged it (and several surrounding towns) with the Free and Hanseatic City of Hamburg.
