Žižkov is a cadastral district of Prague, Czech Republic. Most of Žižkov lies in the municipal and administrative district of Prague 3, except for very small parts which are in Prague 8 and Prague 10. Prior to 1922, Žižkov was an independent city.
The district is named after Hussite military leader Jan Žižka. It is situated south of Vitkov hill, site of the Battle of Vitkov Hill on 14 July 1420, where Žižka's peasant army decisively defeated the forces of Sigismund, Holy Roman Emperor.
Žižkov was historically a working-class district, and was sometimes referred to as "Red Žižkov", because so many of its inhabitants supported left-wing parties. Before World War II, it had a reputation as a rough area. This reputation spread across the whole former Czechoslovakia and it was still possible to trace it amongst the people many decades later.
