Nuño Freire de Andrade, o Mao
Nuño Freire de Andrade, called the Bad (el Malo), was a Galician noble of the late Middle Ages, born around 1374. He held wide lordships in the kingdom of Galicia. His harsh rule so enraged his vassals that in 1431 they banded together as the Mad Brotherhood, the first Irmandiño revolt.
Led by the hidalgo Roi Xordo, the rising spread across the bishoprics of Lugo, Mondoñedo and Santiago. Nuño died in 1431, the year of the rising, and was succeeded by his son Pedro Fernández de Andrade II.
