We study a new driving factor of women's inclusion in politics: the economic empowerment of their mothers. We evaluate Swedish microdata on politicians and their parents over fifty years. The results demonstrate a strong intergenerational dynamic from mothers to daughters. Female politicians come from households where their mother is more likely to be employed, earns more in the labour market, and earns a larger share of household earnings. This pattern was strong among parliamentarians in the 1970s and 1980s when female numerical representation increased rapidly in Sweden but is not present in national politics after the introduction of gender quotas in the early 1990s or in local politics.
