In 1983, decades before the #MeToo movement, Marco Antônio Heredia Viveros made two attempts to kill his wife, Maria da Penha. Using a gun, his first attack left Ms. da Penha paraplegic. Afterwards, Mr. Viveros electrocuted and attempted to drown her, though he was unsuccessful. After facing domestic abuse for 23 years, Ms. da Penha reported her husband to the police, and her case inspired the 2006 “Maria da Penha Law,” sanctioned by then-President Luiz Inácio Lula da Silva, imposing stricter punishments for violent acts against women.
In 2015, then-President Dilma Rousseff approved the “Femicide Law,” which classed the killing of women on account of their gender as a heinous crime.
