After the end of World War I in 1918, Italy annexed the southern part of Tyrol, including the Ladin areas. The Italian nationalist movement of the 19th and 20th centuries regarded Ladin as an "Italian dialect", a notion rejected by various Ladin exponents and associations, despite their having been counted as Italians by the Austrian authorities as well. The programme of Italianization, professed by fascists such as Ettore Tolomei and Benito Mussolini, added further pressure on the Ladin communities to subordinate their identities to Italian. This included changing Ladin place names into the Italian pronunciation according to Tolomei's "Prontuario dei nomi locali dell'Alto Adige".
