In the 1970s and 1980s, feminist historians began focusing attention on a much-neglected topic in social and economic history and the history of the family in Latin America—women’s property rights and their evolution. Single women and widows have always had almost the same property rights as men; up until the last quarter of the 20th century, it was married women’s property rights that differed from men’s, largely to women’s disadvantage. The extent of this disadvantage has been widely debated, with much of the literature demonstrating that married women had considerable economic agency, certainly a role not strictly confined to the private sphere. The first part of this essay focuses on women’s property rights, how the legal frameworks differed in colonial Spanish and Portuguese America, and the extent to which these may have varied in practice across the Spanish Empire. This variation becomes more visible as the different countries enacted their own civil codes in the 19th century, and then embarked on a process of reform toward legal gender equality in the 20th century. The emergence of the interdisciplinary field of women/gender in development in the 1970s and 1980s also drew social scientists from across disciplines to the study of gender inequality in the ownership of assets and wealth. Much of this literature focuses on specific assets, such as land or businesses or financial assets, and on how gender inequality in their ownership might condition other outcomes for women. This focus on women’s economic empowerment became more explicit in the 1990s with the development of household bargaining power models, which drew attention to how women’s access to resources, such as assets or income, conditioned their agency or role in household decision-making, and in turn, their capabilities. Hence, in the second part of this essay we turn to the literature—both quantitative and qualitative, historical and contemporary—on women’s ownership of specific assets, their relative wealth, and why it matters.
