The Roots of Equality?: Marital Age Homogamy and Female Agency in Lesotho, 1880-Present

Age homogamy is an established proxy for female empowerment in historical contexts. This study investigates the long-term trajectory of gender relations in Lesotho, a country that today ranks among the highest in Africa for gender equality. We ask: are its characteristically low levels of marital age hypergamy a recent development or a historical feature? Analyzing parish registers from 1880 to 1939 and comparing to contemporary Demographic and Health Surveys (2004–2014), we demonstrate a striking continuity in spousal age gaps and the derived Girlpower-Index over more than a century. After excluding widows, divorcées, and custom marriages to ensure a consistent sample, our analysis of 3,575 historical records reveals distributions and index values nearly identical to those of the 21st century. This finding challenges narratives that attribute contemporary African marriage patterns solely to recent modernization. The persistence of the Girlpower-Index suggests a possible deep-seated pattern of female agency, indicating that the foundations of Lesotho’s modern gender profile may have been established well before the contemporary era. This study underscores the critical importance of historical demographic data for contextualizing contemporary social structures in Africa.
