Socialism is an ideology that developed as a consequence of the Industrial Revolution. Efficient machine production led to quick profits, which in turn, led to the exploitation of workers. Advocates of socialism spoke about saving the working class from this exploitation; some, like Robert Owen, even attempted to help such people on their own. In his cotton mill in New Lanark, he promoted communal living for poor people and workers. Robert Owen is considered to be the "Father of British Socialism."
