Rio Branco Law

The Rio Branco law (), also known as the Law of Free Birth ("Lei do Ventre Livre"), named after its champion, Prime Minister José Paranhos, Viscount of Rio Branco, was passed by the Brazilian Parliament on September 28 in 1871. It was intended to provide freedom to all newborn children of slaves, and slaves of the state or crown. Slaveholders of the children's parents were to provide care for the children until the age of 21, or turn them over to the state in return for monetary compensation.
The law was the beginning of an abolition movement in Brazil, but it turned out to be more of a legal loophole than a radical measure. Only a few people were freed under the law, while more than one million people continued to be held as slaves. This law had more of an influence in the northern part of the country, which was leaning toward wage rather than slave labor.
Many of those freed under the Rio Branco law migrated to the north to work for wages on the plantations. The Rio Branco law was the first step toward abolition of slavery in Brazil. It was ultimately abolished on May 13, 1888, with the adoption of the "Lei Áurea".
Commemoration.
28 September is International Safe Abortion Day. The day was first celebrated as a day of action for decriminalization of abortion in Latin America and the Caribbean in 1990 by the Campaña 28 Septiembre. In 2011, the Women's Global Network for Reproductive Rights (WGNRR) declared 28 September as an international day. The date was chosen to commemorate the passing of the Law of Free Birth.
