After the First World War, despite the fact that its inhabitants were almost entirely German-speaking, South Tyrol was assigned to the Kingdom of Italy by the Treaty of Saint-Germain and the name officially was changed to "Alto Adige". This happened on the basis of the wishes of the Italian irredentists, who considered the Alto Adige as a geographical territory of Italy and based this on the fact that originally the territory had been mostly of "Ladin language" until the fourteenth century. Besides, the fascist government favoured the industrialisation of the province to attract Italian immigrants: as a result of this "Italianisation", today 120,000 people or 23% of the population down from 135,000in 1960 (35%) use Italian as their mother tongue.
