Bochum

Bochum is a city in North Rhine-Westphalia, western Germany. It is located in the Ruhr area and is surrounded by the cities of Essen, Gelsenkirchen, Herne, Castrop-Rauxel, Dortmund, Witten and Hattingen. Bochum dates from the 9th century, when Charlemagne set up a royal court at the junction of two important trade routes. It was first officially mentioned in 1041 by the name Cofbuokheim in a document of the archbishops of Cologne. Originally, it may have meant "Brookhome" or "Bacheim" and later seems to have gained the notorious reputation of "Bookhorn" or "Horn Book". In 1321, Count Engelbert II von der Marck granted Bochum a town charter, but the town remained insignificant until the 19th century, when the coal mining and steel industries emerged in the Ruhr area, leading to the growth of the entire region.
