Textile manufacture during the Industrial Revolution in Britain was centred in south Lancashire and the towns on both sides of the Pennines. In Germany it was concentrated in the Wupper Valley, Ruhr Region and Upper Silesia, in Spain it was concentrated in Catalonia while in the United States it was in New England. The main key drivers of the Industrial Revolution were textile manufacturing, iron founding, steam power, oil drilling, the discovery of electricity and its many industrial applications, the telegraph and many others. Railroads, steam boats, the telegraph and other innovations massively increased worker productivity and raised standards of living by greatly reducing time spent during travel, transportation and communications.
