Recently, women’s presence on top boards of directors has significantly increased, challenging the long standing of male-led corporate elites. In light of the still-developing literature, this article provides a century-long examination of women’s entry into the Spanish corporate elite, offering several original contributions. In addition to its pioneering input into the country’s historiography, the work uses a holistic model to introduce a comparative European approach. Moreover, it empirically examines the significant yet previously unexplored impact of elite training institutions on the advancement of female directors as well as their arrival through a national holding company and their presence in leading publicly traded companies. Findings showed four distinct stages in their trajectory: discriminatory exclusion, during the first third of the twentieth century; exceptional inclusion, with early positions in their family-owned firms; gradual incorporation, with increased political representation and expanded academic access in the latter decades of the last century; and promotion, supported by twenty-first-century political strategies, while still revealing the handicap of women’s delayed entry into the corporate network.
