The origins of feminism in Brazil trace back to the 19th century. During the Empire of Brazil, some jurists attempted to legalize women's suffrage, with or without the consent of the husband. Later, the republican constitution of 1891 did not exclude women from voting, because they were not considered individuals who could have rights. That made some women request, without success, their inclusion among the voters. The 1891 constitution initially had a clause that gave women the right to vote, but it was abolished in its last version because the idea that politics was not an honorable activity for women prevailed.

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.
