Bertha Maria Júlia Lutz was a Brazilian zoologist, politician, and diplomat. Lutz became a leading figure in both the Pan American feminist movement and human rights movement. She was instrumental in gaining women's suffrage in Brazil and represented her country at the United Nations Conference on International Organization, signing her name to the United Nations Charter and championing the inclusion of Article 8 in the Charter. In addition to her political work, she was a naturalist at the National Museum of Brazil, specializing in poison dart frogs. She has four frog species and two lizard species named after her.

Women's societal roles in Brazil have been heavily impacted by the patriarchal traditions of Iberian culture, which holds women subordinate to men in familial and community relationships. The Iberian Peninsula, which is made up of Spain, Portugal and Andorra, has traditionally been the cultural and military frontier between Christianity and Islam, developing a strong tradition for military conquest and male dominance. Patriarchal traditions were readily transferred from the Iberian Peninsula to Latin America through the encomienda system that fostered economic dependence among women and indigenous peoples in Brazil. As the largest Roman Catholic nation in the world, religion has also had a significant impact on the perception of women in Brazil, though over the past century the Brazilian government has increasingly broken with the Catholic Church in regard to issues related to reproductive rights.
