The Basque witch trials of the 17th century represents the last serious attempt at rooting out witchcraft from Navarre by the Spanish Inquisition, after a series of episodes erupting during all the 16th century following the end of main military operations in the conquest of Iberian Navarre, until 1524. The trial of the Basque witches began in January 1609 at Logroño, near Navarre, bordering on Basque territory.
