At the end of the nineteenth century, when pope Leo XIII issued the encyclical 'Rerum
Novarum', Maastricht too had already a long tradition of welfare care. For instance, there were
the house 'the twelve Apostles' for old men, and the Saint Vincent organisation with the 'ladies
of Charity'. But now, things would be tackled in a more systematic way. And this should be done
without delay, because the printer Willem Vliegen intended to propagate Socialism in the town.
Catholic leaders like monseigneur Rutten organised the Catholic emancipation of the workers. Then the workers
district Blauwdorp (Blue Village) was built.
