ories were set up there to take advantage of the excellent Midlands infrastructure and the availability of large seams of cheap coal for fuel. Another typical boom town is Trieste in Italy.

At the beginning of the First World War, the former fishing village with a deep-water port, which used to be small but geographically centrally located, was the third largest city of the Habsburg monarchy.
