To prevent such a state of affairs, Marx advised working men of all countries to unite and to fight for a number of political and economic measures which he had enumerated in a Manifesto in the year 1848, the year of the last great European revolution.
These views of course were very unpopular with the governments of Europe, many countries, especially Prussia, passed severe laws against the Socialists and policemen were ordered to break up the Socialist meetings and to arrest the speakers. But that sort of persecution never does any good. Martyrs are the best possible advertisements for an unpopular cause. In Europe the number of socialists steadily increased and it was soon clear that the Socialists did not contemplate a violent revolution but were using their increasing power in the different Parliaments to promote the interests of the labouring classes. Socialists were even called upon to act as Cabinet Ministers, and they co-operated with progressive Catholics and Protestants to undo the damage that had been caused by the Industrial Revolution and to bring about a fairer division of the many benefits which had followed the introduction of machinery and the increased production of wealth.
