isolated populations. Starting in the very early Middle Ages, the area was mostly ruled by the County of Tyrol or the Bishopric of Brixen, both belonging to the realms of the Austrian Habsburg rulers. The area of Cadore was under the rule of the Republic of Venice. During the period of the Holy Roman Empire of the German Nation and, after 1804, the Austrian Empire, the Ladins underwent a process of Germanization. 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. Following the end of World War II, the Gruber-De Gasperi Agreement of 1946 between Austria and Italy introduced a level of autonomy for Trentino and South Tyrol but did not include any provisions for the Ladin language. Only in the second autonomy statute for South Tyrol in 1972 was Ladin recognized as a partially official language. Status Ladin is officially recognised in Trentino and South Tyrol by provincial and national law. Italy signed the European Charter for Regional or Minority Languages of 1991, but it has not ratified it so far. The charter calls for minority rights to be respected and minority languages, to which Ladin belongs, to be appropriately protected and promoted. Starting in the 1990s, the Italian parliament and provincial assembly have passed laws and regulations protecting the Ladin language and culture. A cultural institute was founded to safeguard and educate in the language and culture. School curricula were adapted in order to teach in Ladin, and street signs are being changed to bilingual. Ladin is also recognized as a protected language in the Province of Belluno in Veneto region pursuant to the Standards for Protection of Historic Language Minorities Act No. 482 (1999). In comparison with South Tyrol and Trentino, the wishes of the Ladins have barely been addressed by the regional government. In a popular referendum in October 2007, the
