Input: Question: What country is Zeesen a part of? Passage:The name "Lord Haw-Haw of Zeesen" was coined in 1939 by the pseudonymous Daily Express radio critic Jonah Barrington, but this referred initially to Wolf Mittler (or possibly Norman Baillie-Stewart). When Joyce became the best-known propaganda broadcaster, the nickname was transferred to him. Joyce's broadcasts initially came from studios in Berlin, later transferring (because of heavy Allied bombing) to Luxembourg and finally to Apen near Hamburg, and were relayed over a network of German-controlled radio stations that included Hamburg, Bremen, Luxembourg, Hilversum, Calais, Oslo, and Zeesen. Joyce also broadcast on and wrote scripts for the German Büro Concordia organisation, which ran several black propaganda stations, many of which pretended to broadcast illegally from within Britain. His role in writing the scripts increased over time, and the German radio capitalized on his public persona. Initially an anonymous broadcaster, Joyce eventually revealed his real name to his listeners; and he would occasionally be announced as "William Joyce, otherwise known as Lord Haw-Haw". Urban legends soon circulated about Lord Haw-Haw, alleging that the broadcaster was well-informed about political and military events to the point of near-omniscience.
