The idea of the “mamma italiana” is one of the most widespread and recognizable stereotypes in perceptions of Italian national character both within and beyond Italy. This figure makes frequent appearances in jokes and other forms of popular culture, but it has also been seen as shaping the lived experience of modern-day Italians of both sexes, as well as influencing perceptions of Italy in the wider world. This interdisciplinary collection examines the invented tradition of mammismo but also contextualizes it by discussing other, often contrasting, ways in which the role of mothers, and the mother-son relationship, have been understood and represented in culture and society over the last century and a half, both in Italy and in its diaspora.
