Alberti and Juan José Castelli, all three of Italian descent, were part of the May Revolution and the Primera Junta. The Italian community had already grown to such an extent that in 1836 the Kingdom of Piedmont-Sardinia sent an ambassador, Baron Picolet d'Hermilion. However, the stream of Italian immigration to Argentina became a mass phenomenon only from 1880 to 1920, during the Great European immigration wave to Argentina, peaking between 1900 and 1914, about two million settled from 1880 to 1920, and just 1 million from 1900 to 1914. A small number of Italo-Albanians have also emigrated to Argentina from Southern Italy. In 1887, Italians accounted for 60.4% of all immigration to Argentina, then there was a decrease as the percentage of Spanish immigration increased. The effect of Italian immigration to Argentina was important for the constitution of Argentine society. In Argentina there are influences of Italian culture that are still evident today. Outside of Italy, Argentina is the country with the highest percentage of Italians, and the one with the greatest examples of Italian culture. In 1914, Buenos Aires alone had more than 300,000 Italian-born inhabitants, representing 25% of the total population. The Italian immigrants were primarily male, aged between 14 and 50 and more than 50% literate; in terms of occupations, 78.7% in the active population were agricultural workers or unskilled laborers, 10.7% artisans, and only 3.7% worked in commerce or as professionals. The outbreak of World War I and the rise of fascism in Italy caused a rapid fall in immigration to Argentina, with a slight revival in 1923 to 1927 but eventually stopped during the Great Depression and the Second World War. After the end of the war, from 1946 to 1957, another massive wave of Italians moved to Argentina, this time numbering about 380,000. A small number of Istrian Italians and Dalmatian Italians emigrated to Argentina during the Istrian-Dalmatian exodus, leaving their homelands, which were lost to Italy and annexed to Yugoslavia after the Treaty of Peace with Italy, 1947. The substantial recovery allowed by the Italian economic miracle of the 1950s and 1960s eventually caused the era of Italian diaspora abroad to end, and in the following decades, Italy became a country with net immigration. As of 2016, 527,570 Italian citizens still lived in Argentina. In 2011, it was estimated that at least 25 million Argentines (62.5% of the country's population) have some degree
