At the end of the 19th century, Trieste was the largest Slovene city, with more Slovene inhabitants than even Ljubljana.[4] The Austrian census of 1911 recorded 56,845 Slovene speakers,[5] compared to 41,727 in Ljubljana (part of the general Austrian census of 1910). They were the largest ethnic group in 9 of the 19 urban neighbourhoods of Trieste, and represented a majority in 7 of them.[6] The Italian speakers, on the other hand, made up 60.1% of the population in the city center, 38.1% in the suburbs, and 6.0% in the surroundings. They were the largest linguistic group in 10 of the 19 urban neighbourhoods, and represented the majority in 7 of them (including all 6 in the city centre). Of the 11 villages included within the city limits, the Slovene speakers had an overwhelming majority in 10, and the German speakers in one (Miramare).
After being ceded from multiethnic Austria, the Italian nationalist milieus sought to make Trieste a città italianissima, committing a series of attacks led by Black Shirts against Slovene shops, libraries, lawyers' offices, and the central place of the rival community in the Trieste National Hall.[7] Forced Italianization followed, and by the mid-1930s several thousand Slovenes, especially intellectuals from the Trieste region, emigrated to the Kingdom of Yugoslavia and to South America.
Non-Austrian citizens, among them 75% from Italy: 38,597 (16.82%)
