The maiden speech– the first speech given by a newly elected member of parliament (MP)– is a tradition in many parliaments, a personalized rite of passage to political power. As ethnic minority MPs remain relative newcomers, the maiden speech is, for them, even more politically charged. How do ethnic minority MPs represent their identities in this transformative moment? Our data set includes 93 ethnic minority MPs who have held a seat in the Dutch parliament, covering 88 maiden speeches, spanning 11 cycles (1986–2023). The diachronic and intersectional analysis shows that the relation between descriptive, substantive and symbolic representation for historically marginalized groups fluctuates and is influenced by the political environment. The ‘firsts’ of a particular gender/ethnicity intersectional group are less likely to narrate a minority identity than non-firsts. Progressive party ideology influences the extent to which ethnic minority MPs emphasize an (intersectional) minoritized identity. Personal stories and family histories are often used to counter stereotypes, unmute silenced cultures and share values. The focus on the maiden speech as a political narrative sheds light on the blurry lines between substantive, symbolic and descriptive representation. The political narrative is a strategic tool for MPs from historically disadvantaged groups to represent collective identities.
