Italian irredentism in Nice
Italian irredentism in Nice was the political movement supporting the annexation of the County of Nice to the Kingdom of Italy. According to some Italian nationalists and fascists like Ermanno Amicucci, Italian- and Ligurian-speaking populations of the County of Nice (Italian: Nizza) formed the majority of the county's population until the mid-19th century.
