 As a mountain municipality, Rorà was touched by the phenomenon of emigration, in the second half of the nineteenth century (especially towards France and South America, founding the Argentinean town of Alejandra, with whom the Municipality is twinned), and depopulation; unlike other municipalities, however, it was able to combine a poor agricultural economy with a more profitable and industrial activity, until the nineteenth century with the production of lime, and later with the processing of the Luserna stone.During the period of the Resistance, other painful events affected the town, as in general Val Pellice.The fact that at that time Rorà hosted a group of families from the Jewish community of Turin was quite particular.
