One of these problems was the fact that she was illiterate. Juana was unable to read or write and these two skills would have been very useful to her. In fact, she couldn't even sign her name in legal documents and instead marked a cross on them. Briones was a very successful business owner, rancher, and Curandera, who even trained her own nephew. She did everything from being a midwife to treating small pox. She was able to defy the boundaries sexism posed at that time. She even owned 5 rancheros during her life, which were run by Indian slaves. In 1850 Juana's ownership of her land was put into question because California was admitted into the United States. The U.S. took away the land of many Californios, but Juana defended her land using friends such as Maximo Martinez to defend her in the U.S. Land Commission Hearings. One of Juana's properties, which she inherited after her former husband died was in San Fransisco. The case for claim to this land went all of the way to the United States Supreme Court who decided the land truly belonged to Juana. Juana Briones de Miranda faced many hardships though out her life but found a way to fight brought every single one of them. She had an abusing alcoholic husband, was illiterate, faced sexism, and had to battle the United States token her land after California was admitted into the U.S.
Juana died on December 3rd, 1889, living to be 87 years
