The modern period of the kingdom of Galicia began with the murder or defeat of some of the most powerful Galician lords, such as Pedro Álvarez de Sotomayor, called Pedro Madruga, and Rodrigo Henriquez Osorio, at the hands of the Castilian armies sent to Galicia between the years 1480 and 1486. Isabella I of Castile, considered a usurper by many Galician nobles, eradicated all armed resistance and definitively established the royal power of the Castilian monarchy. Fearing a general revolt, the monarchs ordered the banishing of the rest of the great lords like Pedro de Bolaño, Diego de Andrade or Lope Sánchez de Moscoso, among others.
