Clara Campoamor was a significant figure in the early 20th-century feminist movement in Spain. A lawyer by profession, she dedicated her life to advocating for women's rights, particularly the right to vote. In 1931, as Spain began to draft a new constitution following the proclamation of the Second Spanish Republic, Campoamor seized the opportunity to push for women's inclusion in the legislation. The Constituent Cortes, tasked with creating the new constitution, became a battleground for debates on numerous progressive reforms, including the recognition of women's suffrage.

Clara Campoamor passionately argued before her fellow lawmakers that granting women the right to vote was essential for achieving true democracy and equality in Spain. Her compelling rhetoric and insistence on rational discourse were crucial in swaying opinions among her peers. Despite facing fierce opposition and societal stereotypes that relegated women to domestic roles, her resilience and articulate arguments prevailed. Ultimately, her efforts culminated in the historic achievement of women gaining the right to vote, becoming a vital aspect of the constitution established in 1931.

The inclusion of women's suffrage marked a significant leap forward in Spain's social fabric and was a pivotal moment in the global feminist movement. It not only empowered women but also challenged the deeply entrenched patriarchal norms within Spanish society. Campoamor's success highlighted the potential for legal reforms to drive social change, a lesson that resonates in feminist movements across the world.
